Evolution Characteristics of Main Agronomic Traits,Yield and Quality of Early and Middle Ripe Cotton Varieties in Regional Trial of Xinjiang from 2011 to 2020
摘要
Abstract
The evolution characteristics of agronomic traits,yield and quality of early and middle ripe cotton varieties in regional trial of Xinjiang from 2011 to 2020 were comprehensively analyzed.The results showed that the growth period,node of first fruit branch,number of fruit branches and seed finger of test varieties in Xinjiang cotton area were significantly decreased with the year,and the pre-frost flower rate was significantly increased with the year.Boll number per plant,total boll number,boll weight,seed cotton per unit yield,lint per unit yield and lint per unit yield before frost were significantly increased with the year,and only the lint percentage fluctuated slightly and showed a decreasing trend.The fiber length,uniformity,fiber strength,yellow degree and spinning consistent index were significantly increased with the age.The Micronaire decreased and was in the normal range,and the fiber elongation and reflectance were significantly decreased.In short,in the past 10 years,the growth period of early and middle maturing cotton varieties in Xinjiang was shortened.Plant height was stable around 75 cm,and yield was increased.Micronaire was moderate,and fiber quality was significantly improved,which could meet the requirements of machine-picked cotton variety characteristics.关键词
