实行棉花留叶枝简化栽培 ,应选择棉花营养生长较旺盛的品种类型 ,根据品种的生长发育特性以及当地的土壤肥力水平 ,适当降低密度 ,利用叶枝 ,结合适度化控可达到高产、优质的目的。试验结果表明 ,采用留叶枝简化栽培的适宜密度应比常规栽培的密度降低 5 %～ 10 % The implementation of the cotton leaf twigs simplified cultivation should choose the type of cotton vegetative growth is exuberant species, according to the growth and development of varieties and local soil fertility levels, appropriate to reduce the density, the use of leaflets, combined with moderate chemical control can achieve high yield, high quality purposes. The results showed that the appropriate density of leaf-leaved cultivation should be reduced by 5% -10% compared with that of conventional cultivation
