Watermelon cultivation knowledge

First, choose good varieties.

Watermelon resources in our province are rich, and there are many excellent varieties, such as black-skinned walnut big melon, Maya melon and small melon Huadong No.24 in Huaibei. Thin skin, crisp water and sweet taste. However, attention should be paid to prevent hybrid degeneration of varieties and reduce varieties, yield and quality.

Second, cultivate strong seedlings.

After transplanting the melon seedlings into the field, the seedlings can be delayed quickly, live early and grow early, so that the fruit can bear fruit before the arrival of the mildew and rain season, achieving the goals of early maturity, high yield and high quality. The specific method of raising seedlings is:

1. Build a seedbed. Watermelon seedbed should be built near Gua Tian, with good drainage and irrigation and convenient management. Generally, plastic film arch seedbed is adopted, with a length of 15-20 feet and a width of 2.5-3 feet. After the seedbed is completed, 90% to 800 times of crystal trichlorfon preparation solution is poured at the bottom of the seedbed to kill the pests remaining underground. Where conditions permit, seedlings can be raised in nutrient bowls.

2. Sow and raise seedlings. According to the climate in our province, watermelons are generally planted from late March to mid-April. Before sowing, carefully select seeds, eliminate shriveled grains, insect grains and moldy grains, and choose full seeds. Soak melon seeds in cold water 12 hours before germination, then rinse the dirty things on the surface of seeds with clear water and put them in the germination place. The germination temperature should be kept at 30-32℃, and the humidity should not be too high, so that the hands wrapped with gauze can not squeeze out water. During the germination period, the seeds can be washed no longer. When checking the germination, just change the gauze, usually three or four times, and always keep the surface of the seeds non-sticky and the gauze not yellow, and the seeds can germinate and sow in about two days.

You can sow in sunny days. Before sowing, water is poured into the nutrition bowl, then a germinated seed is placed in the center of each nutrition bowl, the bud tip is placed obliquely downward into the bowl, covered with 2-3 cm thick soil, covered with a film, and the periphery is flattened.

Watermelon cultivation method

1. Land selection and soil preparation: Watermelon fields should be selected with high terrain, open air, good drainage, deep soil layer and fertile soil, preferably sandy loam. Watermelon rotation, continuous cropping is prone to wilt, carbon verticillium wilt and other diseases, affecting the yield and quality of watermelon. Generally, the interval between paddy field rotation and dry land rotation is 3-5 years and 7-8 years respectively.

During soil preparation, furrows are dug to make melon ridges, and decomposed manure or compost is applied to holes under the ridges as base fertilizer, with the dosage of 3000-5000 kg per mu and 30-50 kg of calcium superphosphate. Generally, the border is 5.5 ~ 6 feet wide, and deep ditches are opened around the border and the ridge, and the depth of the ditches is lower than that of planting holes, so as to reduce the groundwater level and facilitate irrigation and drainage, flood control and drought prevention.

2. Transplantation and management:

① Watermelon seedlings usually take 30 days, and two or three pieces can be planted and transplanted in real time. Watermelons in our province are mostly planted in late April or early May. When transplanting, it is best to choose a sunny afternoon, open a hole on the melon ridge, peel off the nutrient bowl of the melon seedlings, put the completely flat nutrient soil into the hole, tightly enclose it with loose and smooth fertile soil, cover it with nutrient soil, and then water it to make it closely combined with each other, taking care not to let the nutrient soil crack on the top of the head.

Field planting, more than 600 small melons and more than 500 large melons per mu, with a row spacing of 5. 5-6 feet, spacing between plants is 65438 0.6-65438 0.8 feet.

② After the seedlings were moved into the field, it was rainy and the temperature was lower than the seedbed. In order to promote early seedling and early planting, field management should be strengthened in time, which is the key to early maturity and high yield.

After the seedlings survive, water them two or three times in sunny days with decomposed dilute human excrement urine, or water them with 0.3% urea aqueous solution, and water one kilogram per plant to make the seedlings strong. When topdressing, combine loosening soil and cultivating soil to keep soil moisture, make it breathe air, promote the root of melon seedlings and grow better.

Watermelon operation

Diuretic action

Because watermelon has diuretic effect, coupled with high water content, the amount of urination will increase after eating watermelon, thus reducing the content of bile pigment and making the stool unobstructed, which has a certain effect on treating jaundice. In addition, the diuretic effect of watermelon can also excrete salt and reduce edema, especially leg edema. Watermelon is a natural leg-beautifying fruit for women whose legs are numb and swollen after sitting in front of the computer for a long time.
