棉花具有无限生长习性,其株型和大小可因品种和栽培条件的不同而出现显著差异。采用以化学调控为主的多种栽培措施,能有效地调节棉花的株型和大小,从而塑造出理想的高产群体结构,达到优质、高产、高效的目的。 1.选择品种。应选择株型紧凑、结铃集中或株型和结铃部位相对紧凑的品种。 2.增加密度。采用株型栽培技术后,棉花株型较为紧凑,减少了遮光影响,因此应适当加大密度,靠群体夺高产。一般要求春棉每亩4000～5000株,夏棉
Cotton has an infinite growth habit, its plant type and size may vary significantly due to different varieties and cultivation conditions. The use of a variety of chemical control-based cultivation measures can effectively adjust the cotton plant type and size, so as to create the ideal high-yield population structure, to achieve high-quality, high yield, high efficiency. Choose a variety Should choose a compact plant type, boll concentration or plant type and boll sites relatively compact varieties. Increase the density. Plant-type cultivation techniques, the cotton plant type is more compact, reducing the impact of shading, it should be appropriate to increase the density, by the group to win high yield. General requirements spring cotton 4000 ~ 5000 plants per acre, summer cotton
