板栗嫩枝嫁接是繁育优种苗木和改造低产劣种树的一项新技术。该项技术易掌握,与普通硬枝嫁接比较,具有投资少,工效高的优点。我们经3年(1990～1992年)田间嫁接试验,成活率达90％以上。现将嫁接方法介绍如下: (一)嫁接时期 5月下旬至6月上旬为嫁接适期,此期嫁接成活率高,生长量大。如嫁接过早, Chestnut shoot grafting is a new technology for breeding elite seedlings and for transforming low-yielding inferior trees. The technology is easy to grasp, compared with ordinary grafting, with less investment, high efficiency advantages. After three years (1990 ~ 1992) field grafting experiments, we have a survival rate of more than 90%. Grafting methods are introduced as follows: (a) grafting period from late May to early June for grafting suitable period, this period of graft survival rate, growth. Such as early grafting,
