大樱桃3种实用纺锤形树形修剪试验

Test on Three Practical Spindle-shape Tree Pruning of Cherry

于2012年开始,进行了大樱桃变则纺锤形、自由纺锤形、高纺锤形3种树形的修剪试验,供试品种为美早,在栽后第7年调查各树形冠幅、冠高、干粗比、枝类组成,并调查各树形的始果时间、逐年产量。结果表明,3种树形第7年均未进入盛果期,产量均低;其中高纺锤形始果迟,但产量较高,变则纺锤形始果早,但后期产量低于自由纺锤形和高纺锤形。

In 2012,the pruning test of three tree-shaped of spindle-shape,free-spindle-shape and high-spindle-shape was carried out.In the 7th year after planting,the crown width,crown height,trunk thickness ratio and branch composition of each tree were investigated,and the initial fruit time of each tree were investigated and the yield was investigated.The results showed that the yield of the three trees did not enter the full fruit stage in the 7th year,and the yield was lower than that of the free spindle and high spindle,among which the yield of the high spindle was late,but the yield of the spindle was higher,and the yield of the spindle was earlier,but the yield of the later stage was lower than that of the free spindle and the high spindle.
