高密度劣质板栗低产果园改造模式的初步研究

A Preliminary Study on the Reconstruction Mode of Low Yield Orchard of High-density Inferior Castanea Mollissma

采用随机区组试验设计法,对高密度劣质板栗低产果园的不同改造模式进行了试验研究,结果表明:高密度劣质板栗低产果园的不同改造模式之间的产量差异极显著,以嫁接换冠+间伐为最佳,板栗园产量高、品质好、经济效益好。

Adopting the experiment design method of randomized block, this article conducts a research on the different reconstruction modes of low yield orchard of high-density inferior Castanea mollissma. The results show that there exist significant differences between the different reconstruction modes. The graft propagating combining with thinning is the best reconstruction mode, which leads to high yield, quality and good economic benefits of the chestnut orchard.
