Narcissus prose

How to cultivate daffodils daffodils belong to Amaryllidaceae and Narcissus. Perennial herbaceous flowers. Bulb hypertrophy, egg shape, brown skin. Narcissus is a triploid plant Although its ovaries are enlarged, it is sterile and cannot reproduce sexually. The distribution center of daffodils is in Central Europe, North Africa and the Mediterranean coast. In China, narcissus is cultivated and distributed in warm and humid areas along the southeast coast. Narcissus is cultivated in Zhangzhou, Fujian and Chongming, Shanghai, and also in some parts of mainland China. The phosphorus stem of Zhangzhou Narcissus is plump and beautiful, and it is easy to sprout foot buds, which are even and symmetrical. Buds are mostly multi-flowered daffodils, and there are two varieties: single flower (Jinzhan Yintai) and double flower (Yulinglong). Shanghai Chongming Narcissus is a single-flowered narcissus with small bulb and dense and thin scales, which is not easy to produce foot buds, and the foot buds are not symmetrical and there are few flower buds. Narcissus cultivated in Beijing are mostly hydroponic narcissus, and rarely cultivated in soil. How to select daffodils before planting and see the bulb shape of daffodils is the first step of selection. It is best to choose those with plump and solid appearance, complete brown bulb skin, no buds and no roots (some roots have grown, which cannot exceed 1 cm, but they are stout and short, and cannot be regenerated due to root cutting). The length of the main bud is not more than 3 cm. The flower buds in the main bulbs of narcissus basically grow horizontally and linearly, so there are more oblate bulbs than ordinary bulbs under the same bulb circumference. It is better to have several symmetrical sub-balls around the base of the main bulb, but the more sub-balls, the better. Too many sub-balls compete for the nutrition of the main ball, which leads to the poor growth of the main ball. Then look at the depression of the bulb tray at the bottom of the main bulb to see if there is mud in the depression at the bottom of the bulb. The bulb disc at the bottom is deeply sunken, and the bulb disc is large and muddy, indicating that the bulb is mature. If the bulb disc at the bottom is shallow and small, it means that the cultivation period is not enough, immature and there are few or no flower buds. Watch the color of the ball: the color mentioned above refers to the color of the outer bulb skin outside the main bulb, which should be dark brown and complete and bright. The outer bulb skin is yellow-brown, and the bulb skin is as thin as garlic skin, indicating that the bulb is underdeveloped or has not been planted for a long time, and there are few flower buds, and some even have no flower buds. Some bulbs are not well protected in the process of storage, transportation and movement, and the bulb skin outside the main bulb is seriously damaged, which makes the bare white bulb shrink and discolor, leading to the decline of bulb quality and poor flower bud growth. Weighing: put the narcissus scale ball in the palm of your hand and shake it up and down a few times to measure its weight. Two scales of similar size, the heavier one is better than the lighter one. If there is mud in the depression at the bottom of the scale ball, it is accurate to remove the mud before weighing. In addition, put the scale ball in your hand and squeeze it gently. If you think the balance ball is strong and elastic, so much the better. If the scales with light weight are soft and inelastic, it means serious dehydration, poor growth after hydroponics, few flowers, short flowering period, light fragrance, and even dumb flowers (dumb flowers are daffodils, flower buds are stunted, buds wither and wither, and cannot bloom). Look at the number of piles: the number of piles refers to the number of buds in the bulb. The so-called "pile number" refers to how many narcissus bulbs can be held in a special bamboo basket (the height of the bamboo basket is 3 1cm, the inner diameter of the basket mouth is 28 cm and the inner diameter of the bottom is 27.5 cm). Light bulbs are small, so there are more baskets. 30 bulbs can fill a basket, and such bulbs are called "30 piles"; 20 bulbs can fill a basket, and such bulbs are called "20 piles"; 10 light bulb can fill a basket. Such a light bulb is called "10 pile". 10 bulbs are more expensive because of the small quantity. Now, due to the convenience of transportation and other reasons, bamboo baskets have been gradually replaced by rectangular cartons in recent years, but the size specifications of the cartons are basically the same as those of bamboo baskets, and the number of piles for holding narcissus bulbs is printed on the cartons. At present, the classification of narcissus bulbs is still determined by the traditional pile number. In order to make the classification more accurate and the purchase and sale norms unified and convenient, the relevant departments stipulate that the classification should be based on how many centimeters around the main bulb of narcissus. At present, there are 10 daffodils on the market, and the circumference of the main bulb is more than 25 cm. 24. 1 ~ 25cm is 20 piles; 23. 1~24 cm is 30 piles; 22. 1 ~ 3cm is 40 piles. If some buds of the main bulb protrude and have not left the main bulb, the number of centimeters of the circumference (generally 1 cm) should be appropriately deducted. Some fans want to know the relationship between the number of bulbs and the number of buds of daffodils. Now the narcissus bulbs on the market are all produced in Zhangzhou, and the geographical and climatic conditions are the same. However, there are some differences in planting management technology, fertilization types, planting row spacing, planting time, irrigation amount and many other factors in each flower shop. There are also differences in the number of buds of bulbs with the same pile number, of course, there will be no big difference. Generally speaking, a 50-pile bulb has about 1-2 buds; 40 bulbs have 3~4 flower buds; 30 bulbs have more than 4 flower buds; 20 bulbs have more than 6 flower buds; 10 bulb has more than 8 flower buds. Cultivation management: before planting, peel off the brown dry skin, remove the soil at the bottom of the bulb, clean the dead roots on the root disk with a straight knife, and be careful not to hurt the new root disk during operation. Then let go, which is beneficial to the side-by-side growth of flower buds. Cut a small gap at 1-2 from top to bottom with a blade, taking care not to hurt the flower bud, and then soak the bulb in clear water for 24 hours. Take the bulbs that have been soaked for a day out of the water, gently wash the mucus flowing from the knife wound with clean emery cloth, absorbent cotton or a small brush, put them upright in the shallow basin of narcissus, and then add water, without crossing the root plate. Planting daffodils and raising daffodils with water can grow and develop only by clean water, so the requirements for water quality are higher. The ideal water quality of hydroponic narcissus is unpolluted well water or spring water. Now most people plant daffodils with tap water and raise daffodils with tap water. It is best to put tap water in a clean basin or barrel in the same environment as planting daffodils for 1-2 days, so that the chemicals in tap water can be volatilized or precipitated before use. If there are too many impurities or chemicals in the water, the root tip of narcissus is easy to deteriorate and mold, especially at high temperature, which will seriously affect the growth and development of narcissus. To raise daffodils, we should not only change the basin water regularly every day, but also spray 1-2 times of fresh water on daffodil plants every day. Be careful not to hurt the roots when changing the basin water, sprinkle the old basin water on the ground and keep the environmental humidity. If the local microclimate is too dry, daffodils will not grow well. In the later stage of planting, if the local microclimate is dry, the bud membrane will be dehydrated and dry, and its toughness will increase. At that time, flower buds will be difficult to break when they bloom, often forming "dumb flowers". When the bract membrane outside the bud is not easy to break, it should be broken manually. If the bract membrane outside the bud is broken by hand, the bract membrane cannot be removed at once. The method of removing the bract membrane should be carried out in three times, so that the buds in the bract membrane have an adaptation process, otherwise it will be unfavorable to the growth of the buds. For the first time, use a clean toothpick to make a small hole vertically on the upper bract (but be careful not to touch the bud in the bract), then hold the upper left side of the bract with your left hand and thumb and forefinger, and hold the upper right side of the bract with your right hand, and gently and forcefully expand the vertical opening to about 0.2-0.3 cm. The second operation was carried out 2-3 days after the first operation, and the bract membrane torn outside the flower bud was removed by camera about 1/3. The third time is 2-3 days after the second operation, and the method is the same as above. Then the outer bract membrane of the flower bud is removed by about 1/3, and finally the bract membrane of about 1/3 is left to protect the base of the flower stalk, so that the narcissus can offer flowers on the scheduled flower viewing day. During the flowering period, if the air is too dry, the flowers will be dehydrated and shriveled, and the flowering period will be shortened. The temperature is closely related to the growth rate and flowering time of daffodils. Narcissus likes warm, humid and sunny, avoids high temperature and has certain cold tolerance. In Beijing, potted daffodils should be placed in a sunny cultivation environment, with an average temperature of 10- 15 degrees during the day and a minimum temperature of 5 degrees Celsius at night. It takes about 45 days on New Year's Day and 30 days on Spring Festival (February). During the whole process of narcissus bulbs from hydroponics to flower failure, the ideal temperature is low at both ends and high in the middle. The early stage is the rejuvenation and rooting period, and the temperature should be lower (5- 10), which can inhibit the growth of leaves and is beneficial to rooting; The medium-term temperature should be higher (10- 15) to facilitate the growth of leaves and buds; When the flowering temperature is lower (7- 10), the flowering period can be prolonged by about one week to delay the senescence of flowers. When planting, be careful not to put daffodils near the radiator or by the fire. High temperature will cause leaves and pedicels to grow white, thin and long, leaves to turn yellow and thin, and lose ornamental value. When the weather is clear and the outdoor temperature is above 5 degrees without wind, put the daffodils in the lee of the outdoor sun in the morning and then move them indoors before sunset, which can prevent the leaves and pedicels from growing white, make the daffodils grow short and strong, and improve the ornamental value of the daffodils. Zhangzhou narcissus also pays attention to carving and water conservation, and the bulbs selected have the shapes needed for carving and cultivating the theme. Choose a phosphorus stem ball with big pile head, short and rectangular figure, slightly exposed main buds, full skin color, smooth site, well-balanced foot buds and no new roots at the bottom. If you want to cultivate the exquisite carving skills and beautiful artistic conception of narcissus with unique charm through carving, the key is the proficiency of carving technology and the management of light and temperature during water conservation. Key points of management and maintenance: 1. Planting method: peel off the bulb skin, remove the mud, remove the roots, wash the outer scales, stand upright in a shallow basin and soak them in water until 1/3. Put them in sunny places during the day and move them indoors at night to control the futile growth of leaves. You can change the water 1 time every day when you put it in the basin for the first time, and every day thereafter. Change it once a week. 2. Nutrient solution: Generally, fertilization is not required. If conditions permit, flowers can bloom better with a little nutrient solution with high phosphorus and potassium when flowering. 3. Sunshine: give enough light, put it in the sun during the day and under the lamp at night. This can prevent the stems and leaves from growing white, and make the leaves broad and solid, with thick green leaves and fragrant flowers. 4. Temperature: Narcissus is here. It can bloom in about 45 days, and the flowering period lasts for more than a month. The temperature in the south is high, and it will bloom in about 26 days. 5. Maintenance: Ensure sufficient sunshine for at least 6 hours every day, and pay attention to indoor ventilation. The weather in the north is dry, so we should spray water on daffodils every day. When the bulbs grow new roots of 1-3CM, the plants can be dwarfed after being treated with 5% paclobutrazol for one week. Experience, but in the past, I mainly looked at flowers, and this year I began to look at the roots. The roots of narcissus are milky white, and they grow very densely and can grow very long. Put the narcissus ball into a tall glass bottle, reduce the water level in the bottle with the extension of the root, and keep the root immersed in water for about 2CM, so that the root grows downward with the decrease of the water level, which can be as long as 40-50CM or even longer. Like an old man with a silver beard on his chest. How come? Perennial herbaceous flowers. Bulb hypertrophy, egg shape, brown skin. Narcissus is a triploid plant Although its ovaries are enlarged, it is sterile and cannot reproduce sexually. The distribution center of daffodils is in Central Europe, North Africa and the Mediterranean coast. In China, daffodils are planted in warm and humid areas along the southeast coast, including Zhangzhou in Fujian and Chongming in Shanghai, as well as parts of the mainland. The phosphorus stem of Zhangzhou Narcissus is plump and beautiful, and it is easy to sprout foot buds, which are even and symmetrical. Buds are mostly multi-flowered daffodils, and there are two varieties: single flower (Jinzhan Yintai) and double flower (Yulinglong). Shanghai Chongming Narcissus is a single-flowered narcissus with small bulb and dense and thin scales, which is not easy to produce foot buds, and the foot buds are not symmetrical and there are few flower buds. Narcissus and its planting method I remember one winter vacation, I went to my grandmother's house in the south for the New Year. There is a pot of daffodils in grandma's living room, which is very eye-catching: its roots are immersed in water, spotless, its leaves are green and vivid, and its flowers are beautiful and fragrant. "I also want to raise daffodils." I said to my mother. So, before the Spring Festival last year, my mother asked someone to bring narcissus bulbs from Fujian. This narcissus bulb is not small, with a big tuber in the middle and four small tubers on both sides, which is a bit like a mother pulling four children. On top of the tuber, a small yellow head leaf bud has appeared. I quickly found a transparent glass basin filled with clear water, carefully put the daffodil bulbs in it, and then spread some colorful rain flower stones to make the flower balls stand firmly in the basin. As soon as the narcissus bulb touches the water, it seems that the water awakens a sleeping fairy. Soon, rice-like root buds appeared under the tuber. A few days later, the small root bud grew into a white and tender root. At the same time, the delicate leaves grew up with a cry and proudly looked at my happy eyes. Pieces of sword leaves are tall and straight, thick, and the lower ends of the leaves are green and white. The green leaves grow longer and deeper, and the green at the tip of the leaves is almost flowing out. Ten days later, my eyes are green! I am very happy. I change water for daffodils every day and hold them in the sun, hoping that daffodils will bloom early. About twenty days later, the leaves of daffodils will grow more than a foot high. One day, I was pleasantly surprised to find that in the lush green leaves, flowers and pods grew. They hid in the leaves, and the buds were tightly wrapped inside. Flower pods grow very fast and can jump up a little every day. In a few days, the bud burst out of the flower pod. The bud was green at first, then gradually became lighter in color, and finally became a white bud. The flowers begin to open, the outer petals extend outward, and the inner petals are tightly closed together. For a long time, the whole flower was in full bloom. One, two, three ... Open white petals and spit out yellow stamens like a game. I approached the flowers, and suddenly, I smelled a refreshing fragrance with a little sweetness. Now, daffodils are placed on my desk, with strong vitality. Just a pot of water is enough, but they can produce beautiful flowers, overflow elegant fragrance, bloom in the cold winter when flowers wither, and add green to our lives. It asks less and gives more. Looking at the slender daffodils, I thought a lot. ......
