棉花生产传统上惯用早抪、稀植,人工整枝,争取“三桃”,生育期长,病虫危害重,管理繁杂,劳动强度大,投资多,产量不高.为了改革栽培技术,提高棉花单产,几年来,我们和裴村大队科研站,共同进行了棉花高密度化学除草、不中耕试验和大田生产示范,取得了较好的成果。1977年示范种植186亩,平均亩产皮棉114.2斤,其中有14.5亩达168斤。1978年示范种植127亩,平均亩产皮棉131.5斤。较常规种植增产2—3成。前茬油(艹才)平均亩产86斤。高密化除棉田在栽培管理上和常规管理不同,也和过去“万株小棵早打顶”不同。
Cotton is traditionally used as a raw material for early harvesting, sparse planting and artificial pruning for the purpose of “three peaches”, long growth period, heavy pests and diseases, complicated management, heavy labor intensity, heavy investment and low yield. In order to reform cultivation techniques and increase cotton Yield, in recent years, we and Pei Cun brigade station jointly carried out cotton high-density chemical weeding, non-tillage test and field production demonstration and achieved good results. Demonstration planted in 1977 186 acres, an average of 114.2 pounds of lint per mu, of which 14.5 acres up to 168 pounds. Demonstration planted in 1978, 127 acres, an average of 131.5 pounds of lint per mu. 2-3% more than the conventional planting. Before the stubble oil (艹 only) an average of 86 pounds per mu. In addition to high-density cotton fields in the cultivation and management of conventional management is different, but also with the past, “a million small tree early morning topping,” different.
