| 摘 要： | 运用水量平衡法计算得出河西走廊中部甘肃省临泽县棉花耗水量为675.5mm,并应采取“5水”或“6水”灌溉,以提高水分利用效率。棉花栽培应推行矮、密、早结合的地膜植棉技术,选用特早熟及早熟陆地棉品种,双株双层高产栽培皮棉产量比对照平均提高74.1％,最高可提高83.1％。

| Abstract: | The water consumption of cotton on Linze County in the Hexi Corridor Region was studied by water equilibrium method. The water consumption is 675. 5mm. 5 or 6 times of irrigation should be applied for promoting water use efficiency. The growing techniques of cotton with plastic film-cover include shon plant, close planting and early seeding. Special early-maturing varieties of upland cotton should be selected. Yield of lint cotton by the cultural method of two plants per bunch with one tall and one short is raised by 74. 1 % in mean yield and by 83.1 % in maximal yield compared with that by local traditionally cultural method. |
