板栗低产大树落冠嫁接技术

Technology of Crown Grafting of Low-yielding Chestnut Trees

板栗实生大树由于树体高大,结果部位外移,产量低,效益差,操作不安全。可通过落冠嫁接,采用多头、多位嫁接,加强夏、秋季管理,保证下一年结果、丰产。实现树体矮化、改劣换优、丰产稳产、安全高效。

Chinese chestnut has the characteristics of large tree,high body height,outward movement of fruit part,low yield,poor efficiency and unsafe operation.Through crown grafting,adopting multiple heads,multiple married,plus strong summer,autumn management,to ensure the next year fruit,abundant production.The realization of the tree body dwarf,change for the better,rich and stable production,safety and high efficiency.
