It is preferred to light, and can be cultivated in soil PH4.5~7.5, the average annual temperature is above 10 degrees, the average temperature during the growing period is 16-20 degrees, and the lowest temperature in winter is minus 25 degrees.

Third, how to plant chestnuts in Qianxi?

1. Spring is the period of flower bud differentiation, spring bud germination and flowering of chestnut seedlings. In order to ensure the yield increase and abundance, the management should be strengthened.

2. Watering: spring is the period of concentrated construction of various organs of Chinese chestnut, metabolism and nutrient work is in urgent need of water, irrigation before germination in early spring can promote the formation of female flowers, which is beneficial to the growth of branches. Planted in mountainous and hilly areas, the soil layer is thin and the function of preserving soil moisture is poor, so it is necessary to spray new high-fat film and cover grass to preserve soil moisture in time.

3. Erase buds: when buds germinate, wipe off too many buds in the middle and lower parts of strong branches, leaving 4-5 large buds and 2-3 buds in medium branches. The sprouting is carried out according to the principle of removing, leaving, leaving and sparse.

4. Some branches grow significantly in two years after grafting, which will restrain the growth of other branches and affect the formation of the crown. When the new shoots begin to grow in spring, Huawang 3 must be sprayed in time to make the plant nutrients return and restrain the branches to grow madly. Without artificial topping and shoot killing, plant main shoots, superfluous buds and bystander growth can be suppressed, growth nutrients can be transformed into reproductive nutrients, flower bud differentiation can be promoted, and the quality of pollen fertilization can be improved. More flowering, more fruit setting, prevent fruit drop, promote development.

5. Castration: without artificial control, the share of male and female flowers is generally 20: 50 ∶ 1. Too many male flowers will consume a lot of nutrients and decrease the output value. Therefore, some male inflorescences should be removed when they are 2 cm long, leaving only 3-5 inflorescences at the top of the new shoot, so as to keep the share of male and female flowers at 5 ∶ 1. In addition, the application of potash fertilizer is also beneficial to the overgrowth of male inflorescences.

6. Fertilization: chestnut should be abundant, in addition to the usual application of nitrogen, phosphorus and potassium fertilizer, the key point is to apply Zhuangguotiling, boron fertilizer and zinc fertilizer. Grasp when the female inflorescence appears, spray Zhuangguotiling plus 0.2% borax, 0.2% zinc sulfate mixture, every 7 days, spray 2 times 3 times in succession. Thicken the fruit pedicel and improve the amount of nutrients transported. Prevent falling flowers, falling fruit, cracking fruit, stiff fruit, beautiful fruit shape, good taste.
