通过 3种不同密度的栽培试验 ,初步摸清了吐鲁番地区陆地棉高产田适宜的密度。结果表明 ,该地区以低密度稀植大棵较易高产 ,单株结铃显著增多 ;低密度和高密度的棉花生育期有缩短的倾向 ;棉花生长中后期叶面积增长量最快的是高密度 ,干物质增长量最快的是低密度。 Through three kinds of planting experiments with different densities, the suitable density of Upland cotton high yield field in Turpan was found. The results showed that the planting density of low-density large-sized trees in the area was higher and the number of bolls per plant was significantly increased. The growth of low-density and high-density cotton tended to shorten, and the fastest growth of leaf area in the middle and late stages of cotton was high Density, dry matter growth is the fastest low density.
