节能温室栽培矮甜李修剪方法研究

Shudy of the pruning method of the Dwarfsweet Plum cultivated in the energy saving greenhouse

通过夏季摘心处理和冬剪方法的对比得出:夏季摘心处理生长量大,果树成形早,定植第1、2年夏剪生长量是冬剪的2～3倍,随着树龄的增大,两者生长量差距减少.中、短、花束状果枝比例也随树龄增大比例增加.

Comparing with pinching in summer and pruning in winter. Our conclusion is that Growth of pinching processing in summer is big, fruit tree takes shape earlier. During Planting one or two yeas growth of pruning in summer is two or three times of that in winter.As the tree age is older, disparity among them is decreases. Ratio of the middle, short and bouquected fruit branch is increasing.
