本文研究的内容可分为两个方面,一是不同群体中产量结构各因素间相互影响的研究,二是对有关产量因素空间分布规律的研究。其目的是通过研究,探讨不同群体的适宜结构及其有关产量性状空间分布的优劣部位,为提高棉花产最与增进品质,提供比较确切的理论依据。一、材料与方法试验地土质为两合土,肥力较高,播前
The content of this paper can be divided into two aspects. One is the research on the interaction between the various factors in the output structure of different groups, and the other is the research on the spatial distribution of the yield factors. The purpose of this study is to provide a more exact theoretical basis for improving the optimum and quality of cotton production by studying and studying the appropriate structure and spatial distribution of yield traits for different groups. First, materials and methods Experimental soil for the two combined soil, higher fertility, before sowing
