种植方式与密度对油后棉生育特性及产量构成的影响
Effects of Planting Density and Planting Mode on Cotton Growth Characteristics and Yield Components of Cotton after Rape
摘要
Abstract
To improve cotton oil two crops production.and to realize the reasonable combination of differnt cotton plan-tiong pattern and the density,in 2013 at four sites of Hunan province a research has been conducted on the influence of planting density and planting ways on the characteristics and output of cotton growth.The result showed that different ways of planting and different planting density will have no significant interaction effects.Among different cultivation ways,the nutrition pot seeding transplanting has the highest yield,lowest dierect seeding,but there was no significant difference.Under the same planing pattern,with the increment of density,fruit branch number and number of bolls per plant decreased.While yield of seed cotton in unit area increased.Under the same density,growth duration of direct see-ding cotton was shortest,number of bolls per plant of nutrition pot seedling were highest,fruit branch number of floating seeding were most,effects of different treatment on boll weight,lint percentage,lingt index,seed index were not signifi-cant.Plant height of direct seeding were highest the cotton output of direct seeding of high density is equal to that of nu-trition pot seeding medium density and float seeding of high density.The research indicates that three planting ways are suitable for cotton cultivation in Hunan,there were no significant diferences between different ways of planting production. Direct seeding daily output is the highest,floating production the minimum.Increasing planting density will be conductive to improve cotton production,which will provide theoretical basis for promoting simplified cultivation in cotton fileld.关键词
