雹灾重播条件下不同棉花品种生长发育、产量及品质的差异比较
Comparative study on growth,yield and quality of different cotton varieties under hail disaster reseeding
摘要
Abstract
[Objective]To screen out the cotton varieties suitable for rebroadcasting after hail disaster.[Methods]The post-disaster cotton replanting experiment was carried out in Shaya County,Aksu Prefec-ture,Xinjiang.Five early and mid-maturing upland cotton varieties suitable for post-disaster rescue and disaster relief were selected as test materials to study the differences in quantity,yield and its constituent fac-tors and main fiber quality traits.[Results]Among the tested varieties,Xinluzao 78 had the shortest growth period of 122 d,the plant height was 106.7 cm,the height of the first fruit branch was 22.6 cm,and the first fruit branch was 6.0 knots.Compared with other tested varieties,the distribution was more reasonable,and it was more conducive to the formation of cotton plant yield in the later stage.The seed cotton and lint cotton yields of Xinluzao 78 both reached the highest among the tested varieties,at 5,534.0 kg/hm2 and 2,343.0 kg/hm2 with fine fiber quality.[Conclusion]The comprehensive analysis shows that the tested variety Zhongxinluzao 78 has better comprehensive performance and can be used as a cotton variety suitable for re-broadcasting after hail disaster.关键词
