棉花节省型生理定向简化栽培技术的研究

A simple culture method with physiological effect in cotton

节省型生理定向简化栽培技术是针对棉花管理繁琐、投入大、收效低而提出的一套栽培技术,经过多年多点试验证明该技术是可行的。本文主要报道该技术体系下,田间种植密度的研究结果,经差异显著性(a=0.05)分析表明,行距×穴距×每穴株数(1.0m×0.17m×3株)为最佳密度组合,即每667m2 12000株,产量超过了170kg。定向剂处理与对照相比达显著差异水平(a=0.01),说明定向剂起到了生理调控作用。

Pruning of cotton plants requires a lot of labors,and planting cotton has been invested much but produced very little effect.In order to make planting cotton become simple,a new culture method called a simple method with physiological effect in cotton was put foreword and was tested by our experiments.This paper described research results of density with new culture method.Statistic analysis showed row spacing(1 meter)×hill spacing(0.17meter)×seeding numbers per hill,namely,12000 seeding per 667m2,was the m...
