摘要
调查分析了湖北省荆州市郊15年生黄花梨(PyruspyrifoliaNakai)的树体状况与适宜负载量的关系。结果表明,在中等管理水平条件下,密植梨树枝组适宜负载量的计算公式为y/kg=1.036x/cm-3.091,主干适宜负载量的计算公式为y/kg=1.602x/cm-12.432(x为枝、干周长,y为产量)。单花序适宜留果量为1～2个。适宜负载量下的叶果比为23 66∶1。
Effects of tree body parameter on suitable crop load of 15-year old Huanghua sand pear( Pyrus pyrifolia Nakai) cultivar were studied in Jingzhou suburban district of Hubei Province. The results showed that in filler plant trees under the mean management level,the calculation formula of fruit-bearing branch group for suitable crop load was y /kg=1.036 x /cm-3.091,the calculation formula of main shaft for suitable crop load was y /kg=1.602 x /cm-12.432( x was circumference of fruit-bearing branch or main shaft, y was suitable crop load). The proper fruit number per-inflorescence was 1～2. The leaf-fruit ratio of suitable crop load was 23.66∶1.
