If the chestnut fruit loses too much water, the sugar content will increase abnormally, and the physiological function will be abnormal, resulting in a decrease in the vitality of the chestnut fruit, a decrease in resistance to various pathogenic bacteria, and a susceptibility to disease, mold, and mildew.

Chestnut (scientific name: Castaneamollissima):

Also known as chestnut, chestnut, chestnut, and chestnut, it is a plant of the genus Castanea in the Fagaceae family. It is native to China and distributed in Vietnam and Taiwan. And in mainland China, it grows in areas with an altitude of 370-2800 meters. It is mostly found in mountains and has been widely cultivated artificially. Chestnuts are rich in nutrients, and their vitamin C content is higher than that of tomatoes and more than ten times that of apples. The minerals in chestnuts are also very comprehensive, including potassium, zinc, iron, etc. Although the content is not as high as hazelnuts, it is still much higher than ordinary fruits such as apples, especially the potassium content is three times higher than that of apples.

Morphological characteristics:

Chestnut is the general name for trees or shrubs in the genus Chestnut of the family Fagaceae (Beechaceae), and there are about 7-9 species. Our country is generally divided into two types, wild chestnut and hybrid improved chestnut. What is commonly grown in our country are improved varieties after cross-culture. They are widely planted in our country because of their large size, sweet taste and strong disease resistance. Chestnuts are native to the temperate regions of the northern hemisphere. Most types of chestnut trees are 20-40 years old. Meter-high drop

Global distribution:

This genus is distributed in Asia, Europe, America and Africa in the northern hemisphere. Among them, the main cultivated species are Chinese chestnut, Xinglong County chestnut, Qianxi chestnut, Houyang chestnut, European chestnut and Japanese chestnut.

American distribution:

American chestnut was originally the main tree species in the eastern United States, and now chestnut tree species also exist in Europe and West Asia.

Growing environment:

Chestnut has a wide range of adaptability to climate and soil conditions. The suitable annual average temperature is 10.5-21.7℃. If the temperature is too high and hibernation is insufficient, it will lead to poor growth and development. If the temperature is too low, the chestnut will easily suffer frost damage. Chestnut likes moist soil, but is afraid of the influence of rain. If there is too much rainfall and the soil accumulates water for a long time, it will easily affect the growth of the root system, especially the mycorrhizae. Therefore, it is not suitable to develop chestnut orchards in low-lying areas prone to waterlogging.

Chestnut is sensitive to soil pH and is suitable for growing on slightly acidic soil with a pH value of 5-6. This is because chestnut trees are high-manganese plants and can activate manganese, calcium, etc. under acidic conditions. ? Nutrient elements are beneficial to the absorption and utilization of chestnuts. ?The Xuzhou area is located on the southern edge of Huangtan Hainan, with an average annual temperature of 13.7-14.1℃ and an annual precipitation of 782-946 mm, which is more suitable for the growth and development of chestnut trees.
