一、技术运用1.栽培密度沙湾县金沟河镇2009～2010年引进1膜8行滴灌栽培技术,棉花种植模式由1膜4行改为1膜8行,667米2种植密度由1.0万～1.2万株提高到1.8万～2.4万株,是一般普通宽膜植棉密度的1.5倍,在中低产田充分发挥了“以密取胜”的优势,依靠坚实的群体,最大限度挖掘棉花群体综合生产潜力,在同等投入基础上,获得30%～50%增产效果,实践证明,采用“以密取胜”的高密度栽培技术,依靠增加密度,提高棉花单位面积株数、总铃数是常规栽培技术的优化组合,效果明显。
First, the use of technology 1. Cultivation density Jinwanhe Town, Shawan County from 2009 to 2010 introduced a film 8-drip irrigation technology, cotton planting patterns from 1 film 4 lines to a film 8 lines, 667 m 2 planting density from 1.0 10,000 to 12,000 to 18,000 to 24,000 strains, which is 1.5 times of the normal broad-leaved cotton-planting density, giving full play to the advantage of “winning by density” in low-yielding fields and relying on a solid group to maximize Excavating the potential of comprehensive production of cotton groups, on the basis of the same input, 30% ~ 50% yield increase effect, practice has proved that the use of “to win by winning ” high density cultivation techniques, by increasing the density and increase the number of cotton per unit area, total Bell number is the optimal combination of conventional cultivation techniques, the effect is obvious.
