新近定名并推广的低酚棉新品种“新陆早三号”在生产上逐渐地显示出其诸多的优势,其种植面积迅速扩大。棉农为挖掘“新陆早三号”的丰产潜力,渴求该品种的栽培技术。为此,笔者对该品种的种植密度和行距进行了研究。 一、试验概况 试验设置在农七师农科所一号地,肥力中等,前茬棉花,生长期田间管理与大田相同。试验采用裂区设计,主因子为密度,设置0.8万株/亩、1.0万株/亩、1.2万株/亩和1.4万株/亩,四个水平;副因子为行距,设置30+60cm宽窄行和70+70cm等行距两个水平。三次重复。小区面积36m~2。
Newly-named and promoted low-phenolic cotton new variety “Xin Lu Zao No. 3” gradually shows its many advantages in production, and its acreage has rapidly expanded. In order to exploit the high yield potential of “Xinluzao 3”, cotton growers are eager for the cultivation techniques of this variety. To this end, the author of the species of planting density and spacing were studied. First, the test profile Test set in the Agricultural Division No. 7 Agricultural One, medium fertility, the former crop of cotton, growing field management and the same field. The experiment adopts split design. The main factor is the density. The density is set at 8,000 plants per mu, 10,000 plants per mu, 12,000 plants per mu and 14,000 plants per mu respectively. Line and 70 + 70cm line spacing two levels. Repeat three times. Area of 36m ~ 2.
