机采棉种植模式下不同棉花品种适应性研究
Study on Adaptability of Different Cotton Varieties Under Planting Pattern of Machine-harvested Cotton
摘要
Abstract
The aim of study is to clarify the morphological,physiological and yield changes of each cotton variety under the machine-harvested cotton pattern and provide a theoretical basis for variety selection in mechanized cotton production in the Yangtze River basin.In the field trial from 2018 to 2019,the low density(45000 plants/hm2)of'Zhongmiansuo 63F2'(a hybrid cotton variety)was used as the control treatment,the growth process,agronomic traits,dry matter accumulation and yield changes of'Zhongmian Suo 63F2','Zhongmian Suo 425'(conventional early-maturing cotton variety)and'Zhongmian Suo 50'(conventional early-maturing cotton variety)were studied under high density(90000 plants/hm2)with the planting pattern of machine-harvested cotton.The results showed that the leaf area index,dry matter accumulation,boll number and yield of each variety under the planting pattern of machine-harvested cotton were higher than those of the control treatment.The boll weight and seed cotton yield of'Zhongmiansuo 63F2'were higher than those of the two early maturing cotton varieties,but it didn't reach the significant level.The conventional early-maturing cotton varieties'Zhongminansuo 425'and'Zhongmiansuo 50'matured earlier and concentrated fruiting,which were suitable for the two-harvest-a-year continuous cropping system in the Yangtze River basin.关键词
