新疆北疆机采棉花铃期栽培管理及适宜气候条件分析

Analysis on Cultivation Management and Suitable Climatic Conditions of Machine Picked Cotton at Boll Stage in Northern Xinjiang

近年来,在全球气候不断变暖的大气候环境影响下,局部极端天气气候事件不断增加,这对新疆北疆棉花的栽培管理提出了更高的要求。通过研究发现,在棉花全生长发育期中,花铃期适宜的气候条件对提高产量和品质影响较大。分析北疆机采棉花铃期的生育特点和栽培管理技术,更加清晰地了解机采棉花铃期对适宜气候条件的具体要求,对提高机采棉的产量和品质有着重要的意义。

In recent years,as the global climate is constantly warming,under the influence of global climate environment,local extreme weather and climate events are increasing,which puts forward higher requirements for cotton cultivation and management in Northern Xinjiang.The results showed that in the whole growth period of cotton,the suitable climatic conditions at flowering and boll stage had a great influence on the improvement of cotton yield and quality.This paper analyzes the growth characteristics and cultivation management technology of cotton boll period of mechanical harvesting in Northern Xinjiang,so as to understand more clearly the specific requirements of machine picked cotton boll period to suitable climatic conditions,which is of great significance to improve the yield and quality of machine picked cotton.
