【Abstract】 Experiments of high yield fine quality planting techniques of Castanea mollissima were conducted in such areas as Baoyingzi, Sijiazi, Yongxing and Hemu in Fengcheng city by taking integrated technological measures such as pruning, top application, spraying chemicals and spraying fertilizers on leaves. The results showed that: the measures increased yield of chestnuts by a big margin, and yield of per tree of Hongguang Castanea mollissima and Liaodan 58 Castanea mollissima increased by 7.12kg and 8.85kg, respectively. Yield reached 1 500～5 340kg if planting 750 trees per hectare,increased by 50%～186% compared with control, output value increased by 7 500～26 700 yuan RMB per hectare,effect was extremely significant.更多还原
