枣棉间作下不同种植密度对棉花生理特性及产量的影响
Study of Different Planting Patterns on Physiological Characteris tics and Yield of Cotton in the Condition of Jujube and Cotton Intercropping
摘要
Abstract
[ Objective ] The purpose of this program was to study the different planting patterns on physiological characteristics and yield of cotton in the condition of jujube and cotton intercropping in order to screen out appropriate cotton planting density. It was expected to provide theoretical basics for the stereoscopic planting pattern in Southern Xinjiang. [ Method ] The field experiments on the effects of 3 planting densities on the photosynthetic characteristics, dry matter and yield of cotton in the condition of jujube and cotton intercropping were conducted. [ Result]The results indicated that the optimum population density of the cotton is 250 100 plantlets/hm2, under which the photosynthetic rate, the transpiration rate, the canopy structure, canopy apparent photosynthesis, dry matter accumulation and distribution and lint yield of cotton were better than those under other densities. [Conclusion]Compared with the monoculture cotton field, jujube and cotton intercropping pattern affects the growth and development of cotton, but appropriate planting density is able to optimize it.关键词
