Most parts of Henan belong to warm temperate and semi-humid monsoon climate, with an average annual temperature of about 65438 05℃. The annual average temperature of chestnut is 10.5~2 1.7℃, so it can be planted. Chestnut is a light-loving tree species. When flowering, the light is sufficient and the air is dry, so it will blossom and bear good fruit. Therefore, chestnut trees should be planted on semi-sunny slopes, sunny slopes or open areas. In order to enhance the light in cultivation practice, the branches in the crown should be properly sparse.

Chestnuts in the north are more drought-resistant and drought-tolerant, while chestnuts in the south are more moisture-resistant and heat-resistant. The annual average temperature suitable for chestnut growth is 10- 15℃, and the temperature in the growing period (April-June-June) is 16-20℃, which is suitable for places where the temperature is not lower than -25℃ in winter.

Although the northern chestnut is drought-resistant, it still has certain requirements for water during its growing period. Proper water supply in new shoots and fruit growth period can improve the quality of new shoots and fruit size; Although southern chestnut is drought-tolerant, it is still necessary to pay attention to drainage and waterlogging prevention in rainy season or during the year. The suitable soil water content of chestnut is 30%-40%. When it exceeds 60%, it is easy to rot. Below 12%, the tree is weak. At 9%, the tree died. Therefore, attention should be paid to irrigation and drainage in cultivation.

Chestnut originated in China, which is one of the earliest famous nuts in China, and its annual output ranks first in the world. Chestnuts in China are of the best quality and rich in nutrition in the world. After frying, its meat is delicate, sweet and delicious, and it is very popular.

Hebei chestnut is rich in resources, and its export volume ranks first in the country.
