Abstract

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 Prefecture, 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 factors 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 rebroadcasting after hail disaster.

摘要：

【目的】 筛选出适宜新疆南疆雹灾后重播的棉花品种。【方法】 在新疆阿克苏地区沙雅县设置灾后棉花重播试验,选取适宜灾后重播的 5 个早中熟陆地棉品种为材料,比较各参试品种在生育进程、主要农艺性状、干物质积累量、产量及其构成因素与主要纤维品质性状上的差异。【结果】 新陆早78号的生育期最短,为122 d;株高为 106.7 cm、果枝始节高度为22.6 cm、始果枝节位为 6.0节;在干物质积累与分配上较其它参试品种更为合理,更加有利于棉株后期产量形成;新陆早78号的籽棉和皮棉产量在参试品种中均达到最高,分别为5 534.0、2 343.0 kg/hm²;纤维品质表现较好。【结论】 参试品种中新陆早 78 号综合表现较优,可以作为雹灾后重播的棉花品种。
