本文通过试验研究,围绕每公顷超1875kg皮棉的高产棉花的密矮群体株型,分析了高产棉花的产量结构,光合效应,成铃时空分布等综合指标及相关关系。讨论了密矮群体株型高产棉花的水肥运筹与生长发育;化学调控与密矮群体株型;促铃描施与开花成铃高峰;库源流等同步栽培技术。提出了增加化控,密矮群体,塑造株型,调整水肥,促进成铃同步栽培体系的核心内容。 In this paper, through comprehensive research on yield-structure, photosynthesis, spatiotemporal distribution of high-yield cotton and other related indicators of high-yielding cotton around Mianyang high-yielding cotton around 1875kg lint per hectare, The strategies of water and fertilizer operation and growth and development of high-yield cotton with plant type and high density in Miya population were discussed. The chemical regulation and the plant type of Mi-dwarf population were also discussed. Proposed to increase the chemical control, Miya population, shape plant type, adjust the water and fertilizer, and promote synchronous cultivation system of bell core content.
