比较免耕栽培及常规栽培2种模式下棉花的生育期、农艺性状、产量以及品质之间的差异,结果表明,免耕栽培的各项指标均略低于常规栽培,其中,实收计产籽棉产量比对照低120 kg/hm~2,应用于新疆南疆的大环境下,籽棉按7元/kg计算,免耕设计较对照少收入860元/hm~2,而免耕设计节省了犁地费用555元/hm~2,因此,免耕栽培实际较常规栽培少收入305元/hm~2。
The results showed that the indexes of no-tillage cultivation were all slightly lower than those of conventional cultivation, among which, the actual yield and yield of cotton The seed cotton yield was 120 kg / hm ~ 2 lower than that of the control, which was applied to the environment of southern Xinjiang. The cost per seed cotton was 7 yuan / kg, and the no-till design income was 860 yuan / hm ~ 2 less than that of the control The cost of plowing 555 yuan / hm ~ 2, therefore, the actual cultivation of tillage less than the conventional cultivation of 305 yuan / hm ~ 2.
