| 摘 要： | 本文主要以棉花为试验材料 ,采用稀穴密株种植方式 ,分析了不同滴灌水量条件下 ,水分在土壤中的运移规律 ,结果表明只有灌水量达到每穴 4 0 0 0mL以上时 ,滴灌水才能达到棉花根系集中层 ,对棉花的生长发育起到促进作用 ,低于 4 0 0 0mL/穴的滴灌水 ,水分利用率较低。

| Abstract: | The experiment was conducted on cotton under the condition of central planting in sparce sockets. The pattern of water movement in soil under different drip irrigation volume were studied. The results showed that only when the irrigation volume reached 4 000 ml/per socket, could the water be distributed on the layer where cotton roots concentrated, and thus promote the cotton growth. When the irrigation water volume was below 4 000 ml/per socket, water using efficiency was low. |
