龙眼疏果方法研究

A study of the method of longan fruit panicle thinning

在疏穗的基础上 ,采用“弧形短截加挖心和扫地”的方法进行龙眼疏果粒 ,收到了极好的效果 :一是速度快 ;二是方法简单 ,容易掌握 ;三是显著地提高了保果率、单株产量、单果重量和固形物含量 ;四是穗形紧凑 ,呈球状 ,美观 ,无残留秃枝梗 ,采收时几乎无需整理 ,大大节约用工。

Basing panicle thinning, longan fruit graines were thinned by a method named “Cutting short in a curve line plus digging center and sweeping the ground” It brought very good results.Firstly, the speed of fruit thinning was very high. Secondly, this method was so simple that everyone could use it easily.Thirdly, raising of fruit-retention rate, yield per tree, individual fruit weight and total soluble solids(TSS) were significant.Fourthly, the fruit panicle was compact,as a ball, no bald branch in it, and needless to repair it after picking, so fruit picking labour could be reduced to large extent
