Castanea mollissima has been adapted to the high temperature and high humidity ecological environment for a long time, and it is better to use local wild or semi-cultivated chestnut (Castanea mollissima) as rootstock for grafting propagation. Castanea henryi can be used as rootstock, but the grafted seedlings grow vigorously, and improper control after planting is easy to delay the fruiting period. Li Mao, as a rootstock, is short and adaptable, but its affinity is poor when grafting.
Moreover, the growth and development in the later stage are poor, the degradation phenomenon is serious, the tree is weak, and the pests and diseases are serious. In addition, Japanese chestnut, American chestnut and European chestnut could not be used as rootstocks of China chestnut because of the differences in ecological conditions and species.
Chestnut is suitable to grow on sandy loam with more organic matter and good ventilation, which is beneficial to root growth and the production of a large number of mycorrhiza. It does not grow well in the soil with high viscosity, poor ventilation and poor drainage (easy to accumulate water) in rainy season. Chestnut is sensitive to soil pH, the suitable pH range is 4-7, and the most suitable is slightly acidic soil of 5-6. Weathered soil in limestone mountain area is mostly alkaline, which is not suitable for developing chestnut. Granite and gneiss weathered soil is slightly acidic and breathable, which is suitable for chestnut growth.
