不同摘心处理对密植蟠桃生长和结果的影响

Effect of Different Pinch Treatment on Growth and Setting Fruit of Amygdalus persica var. compressa Cultivated Highly Densed

以3年生密植早露蟠桃为试材，采用夏季修剪中3种不同长度的摘心处理，研究了摘心对其生长和结果的影响，结果表明：3次摘心在25—30cm的处理都可有效控制新梢生长、调控树势和促进成花，也有利于产量和果实综合品质的提高。各处理中以处理山最佳，产量达31935kg／hm^2，树势中庸，品质上等。

In the paper, effect of different pinch treatment on growth and fruit of Amygdalus persica var. compressa cultivated high was studied by using three-year tree. The results showed that treatment of pinching from 20 to 30 could control effectively growth of shoot tipping, modulate tree growth, promote to form flower and be in favor of improving yield and comprehensive quality. Treat Ⅲ was the best, the yield canoe to 31935kg per hm^2, the growth was normal, and quality was super.
