角倍倍园主要生态因子对五倍子产量的影响

Effects of the main ecological factors on gallnut yield

摘要: 树、藓、虫是五倍子生产中必不可少的3要素，倍园中树、藓、虫数量组配状况直接影响五倍子产量。首次运用正交设计方法，研究了倍树密度、植藓面积和春迁蚜挂放量对五倍子产量的影响，对五倍子产量线性效应的大小顺序为挂虫量>倍树密度>植藓面积；3要素间亦存在明显的交互效应。

Abstract: Tree，moss and aphid are three necessary factors to produce gallnut．The composition of their different quantities directly affects the gallnut yield．By using orthogonal combination design，an experiment was carried out to study the effects of sumac，winter host mosses and spring migrant on yield of gallnut．The results showed that gallnut yield is linearly intluenced by the numbers of sumac(Rhus chinensis Mil1．)，area of winter host mosses(Plagiomnium maximoioziiT．Kop)and quantity of spring migrant(Schlechtendalia chinensis )separatly as well as their different combinations．The amount of spring migrant has the largest effect on gallnut yield,followed by the number of sumac and area of winter host mosses．The results may be useful for cultivation of gallnut.
