芽苗是地上部只有一只接芽的“半成苗”。利用芽苗大田定植,具有下述优点:体积小,运输方便;育苗时间短,可当年育苗,当年建园,缩短育苗周期;根冠比例大,根系相对发达,地上部消耗少。因而定植后成活率高,生长快,成形早,可塑性大,易育成丰产树形。南汇县在桃树生产上大面积应用芽苗定植,已有20多年历史,1985年又采用芽苗定植,一年建成桃园15000亩。获得了很好的经济效益和社会效益。采用芽苗定植时,除注意加强肥水管理外,还要注意以下几点:
Sprouts shoots are only one of the ground above the “half-seedlings.” The use of bud seedling field planting, has the following advantages: small size, easy transportation; seedling time is short, the year seedlings, the park was built to shorten the breeding cycle; root and shoot a large proportion of relatively developed roots, shoots less consumption. Thus high survival rate after planting, fast growth, early forming, plasticity, easy to fertile tree. Nanhui County peach tree production in a large area of application of sprouts, more than 20 years of history, 1985 and the use of sprouts planted a year to build 15,000 acres of Taoyuan. Obtained a very good economic and social benefits. Sprout seedlings planted, in addition to pay attention to strengthening fertilizer and water management, but also pay attention to the following points:
