Can Peng 'an, Nanchong, Sichuan plant apples?

Apple can be planted in Peng 'an, Nanchong, Sichuan. Apples can adapt to most climates. It is the best choice for apple growth between 35-50 degrees north and south latitude. Apples need 1000- 1600 units of heat and 120- 180 days of frost-free weather. Warm during the day and cold at night, and as much light radiation as possible is the premise to ensure good quality. Apples can resist the frost of MINUS 40 degrees, and are planted in temperate regions all over the world.

One: Apple

Apples. ): It's a deciduous tree. Usually trees can be as high as 15 meters, but cultivated trees are only about 3-5 meters high. The trunk is grayish brown, and the bark has fallen off to some extent. The flowering period of apple trees depends on the local climate, but it is generally concentrated in April-May. Apple is a cross-pollinated plant, and most varieties cannot bear fruit by themselves.

Generally, after the apple is planted, it begins to bear fruit in 2-3 years. Fruit is generally red, but it depends on the variety. The fruit of apple tree is rich in minerals and vitamins and is one of the most commonly eaten fruits. The length of fruit growth period is generally 65-87 days for early-maturing varieties, 90- 133 days for middle-maturing varieties and 137- 168 days for late-maturing varieties. Generally speaking, the life span of planted apples can reach 15-50 years.

Two. distribution range

It is widely cultivated in Liaoning, Hebei, Shanxi, Shandong, Shaanxi, Gansu, Sichuan, Yunnan and Tibet. Suitable for hillside terraces, plain mines and loess hills, with an altitude of 50-2500m. Originated in Europe and Central Asia, it has a long history of cultivation and is cultivated in temperate regions all over the world.

Originated in eastern Turkey, the main varieties come from Begonia (there are hundreds of varieties), one of which is Begonia brevifolia, a short compound leaf variety cultivated to improve fertility. China, the United States and France are the main producers of apples (tons), while France, Italy, the United States and Turkey are the main producers of apples (tons/hectare).

Three: growing habits

Apples can adapt to most climates. It is the best choice for apple growth between 35-50 degrees north and south latitude. Apples need 1000- 1600 units of heat and 120- 180 days of frost-free weather. Warm during the day and cold at night, and as much light radiation as possible is the premise to ensure good quality. Apples can resist the frost of MINUS 40℃, and if the temperature is between -2.2℃ and -3.3℃ during flowering and fruiting, the yield will be affected. Compared with other deciduous crops, apples bloom later. Thereby reducing the probability of suffering from frost. However, for some varieties and regions, the frost effect is more obvious there, so an effective anti-freezing system is necessary. It is most suitable for neutral and well-drained soil with pH value of 6.5.

Four: cultivation techniques

Orchards that did not apply base fertilizer in autumn and winter last year should be applied immediately after thawing (but the effect is not as good as that in autumn). After fertilization, if there are irrigation conditions, water should be poured into the garden once, and shallow hoeing should be done in time to preserve moisture. Dry land orchards should be raked to conserve moisture, then fertilized, and then quickly leveled and patted to conserve moisture. Young and weak trees will be covered with "banded" films to increase temperature and keep moisture, thus promoting the robust growth of trees. The fertilization method is to dig a "ring ditch" or "well ditch" with a width of 50 cm and a depth of 50 cm under the crown projection, and apply all the base fertilizers prepared in autumn and mix them evenly with the soil; Sprinkle all the topdressing (multiple compound fertilizers, urea, etc.). ) in the tree tray, then turn into the soil, rake and pat it flat. Fertilization requirements: First, try not to hurt the root with a diameter of 0.5 cm; Second, the topdressing part of the tree tray should keep a distance of 20-30 cm from the trunk to avoid hurting the trunk.

Five: Pest control

The rough skin of fruit trees often hides many diseases, such as hawthorn spiders, caterpillars, curved leaves, rot and so on. After pruning in winter, the trunk, branches, scissors and saws are mainly inspected for decay from mid-February. Later, it was found that the mixture of Bomei 10 degree stone sulfur was added to the 0/00 times solution of "General Tree Protection", and it was repainted half a month later. It can quickly form a protective film on the affected part of tree diseases and suffocate germs. The method is to apply the emulsion with a brush, and then spray the trunk and branches with 100 times (50kg) emulsion for disinfection, which can prevent the rotten virus from landing on the tree, and the diseased skin infected with dead spores begins to fall off after 30 days. The "tree-protecting general" can also be mixed with various pesticides or foliar fertilizers.
