摘　　要：通过对棉花不同密度和打顶时期两项栽培措施的试验研究,得出在温宿县于7月21日左右打顶,以分层分批的打顶方式最能获得高产。在中等肥力条件下,6行30万株/hm2比4行20万株h/m2产量高。Studiesd on cotton planting measures of different densities and top - cutting stages, the results show that mid-fertility cotton filed is better by high - density planting, and the effect of increase production is more prominent by top - cutting on July 21th by layers and stages.
