摘要: 对6个自选棉花(Gossypium spp)早熟新品系进行了品比筛选试验。结果表明,棉花新品系H8010和H208在早熟性、丰产性、纤维品质、农艺性状上均表现出适宜机械化收获的指标要求;筛选出品系H8010的适宜种植密度为60 000~67 500株/hm2,在该种植密度条件下,子棉和皮棉产量均为最高,具有较好的推广应用潜力。

关键词: 机采棉(Gossypium spp), 早熟, 新品系, 密度

Abstract: Through the screening test of six self-selected cotton early maturing lines, the results showed that the new lines of cotton (Gosavwim spp) H8010 and H208 showed suitable mechanized harvest in early maturity, high yield, fiber quality and agronomic traits. The suitable planting density of the new lines of cotton H8010 is 60 000~67 500 plants/hm2. Under this planting density condition, the seed and lint yield are the highest, which has good potential for popularization and application.

Key words: machine picking cotton (Gossypium spp), early maturing, new line, density
