摘要:

明确各品种在机采棉种植模式下形态、生理及产量因子变化,为长江流域棉花机械化生产中品种选择提供理论基础。通过2018—2019年大田试验,以‘中棉所63F2’(杂交棉品种)低密度(4.5万株/hm2)为对照,研究‘中棉所63F2’和‘中棉所425’(常规早熟棉品种)、‘中棉所50’(常规早熟棉品种)等3个棉花品种在高密度(9.0万株/hm2)机采棉种植模式下的品种生育进程、农艺性状、干物质积累及产量变化。结果表明,各品种在机采棉种植模式下,其叶面积指数、干物质积累量、成铃数及产量均高于对照;‘中棉所63F2’单铃重、籽棉产量高于2个常规早熟棉花品种,但未达显著水平。常规早熟棉品种‘中棉所425’、‘中棉所50’成熟较早、集中成铃,适宜长江流域一年两熟模式下连茬种植。

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.
