摘　　要：运用修剪技术控制树冠,可以实现妃子笑荔枝高产目标。试验设控冠修剪、常规修剪和不修剪三个处理。连续四年试验结果表明,控冠修剪有效控制冠幅扩展,绿叶层厚,叶绿素含量高,平均单株产量最高,增产显著,为妃子笑荔枝搭架盖膜栽培推广应用提供了理论依据。To control the crown breadth by pruning technology can achieve the goal to increase the yield of Feizixiao litchi. In the experiment, the litchi trees are divided into three groups, which are treated with different techniques of crown-control pruning, conventional pruning and un-trim.The results of the four-year＇s experiment show that, crown-control pruning can control the crown extension effectively with thick leaf layer and high chlorophyll content. The average yield of single plant is the highest and the increase in yield is notable. All these provide theoretical basis to the popularization and application of steel-frame membrane cultivation of Feizixiao litchi.
