Chestnut is a plant of Castanea in Fagaceae, which is native to China and distributed in Viet Nam, Taiwan Province and Chinese mainland. It grows at an altitude of 370-2800 meters, which is more common in mountainous areas. It has been widely cultivated artificially.
Chestnuts are rich in nutrition, and the content of vitamin C is even higher than that of tomatoes, which is ten times that of apples. The minerals in chestnuts are also comprehensive, including potassium, zinc and iron. Although the content is not as high as hazelnut, it is still much higher than that of ordinary fruits such as apples, especially the potassium content is three times higher than that of apples.
Chestnut has a wide range of adaptation to climate and soil conditions. The suitable annual average temperature is 65438 0.5—265438 0.7℃. Too high temperature and insufficient hibernation will lead to poor growth and development, and too low temperature will easily cause freezing damage to chestnut.
Chestnuts like it? Wet soil, but afraid? The influence of rain and waterlogging, if there is too much rainfall, the soil will accumulate water for a long time, which will easily affect the growth of roots, especially mycorrhiza. Therefore, it is not suitable to develop chestnut orchards in low-lying and waterlogged areas.
Chestnut, right? Soil PH value is sensitive, and it is suitable to grow in slightly acidic soil with pH value of 5-6. This is because chestnut is a high manganese plant, which can activate manganese and calcium under acidic conditions? Nutrient elements are beneficial to the absorption and utilization of chestnut. ? Xuzhou area is located in the southern margin of Huangtan Lake, with an annual average temperature of13.7-14.1℃ and an annual precipitation of 782-946 mm, which is suitable for the growth and development of chestnut trees.
