摘要
根据山西棉区气候特点、当地的土壤肥力基础、生产条件和棉花本身成铃的时空分布规律,经多年试验研究,形成了棉花“密矮”栽培技术体系,取得了显著的增产效应和经济、社会效益。并从气候与棉铃形成关系、棉株成铃时空分布与纤维品质关系以及群体株型与高光效效应关系等方面分析了“密矮”栽培的增产机理。
In this paper, a set of density-dwarf height cultivation technique system in cotton （G hirsutunt L） was established according to the climatic character,local soil fertility, production condition, cotton boll-setting and its distribution law both in time and space in Shanxi cotton production area and mang years＇ experiments. Obvious yield increasing effect and economic and social benefit were achived. Its yield increasing mechanism was analysed through relationship between climate and boll-setting, between boll-setting distribution both in time and space and fiber quatily, plant patterns and high photosynthetic efficiency etc.
