| 摘 要： | 在新疆干旱气候条件下,2009年通过对棉花膜下滴灌进行试验研究,分析了不同灌溉定额和灌水周期对土壤水盐分布及棉花生长的影响。结果表明,灌水周期5d的处理能够达到棉花最适宜的土壤水分范围。在相同的灌水周期下,土壤剖面平均含水量随着灌溉定额的增加而增大。较高灌水频率对根区土壤盐分具有较好的淋洗作用,灌水周期10d的处理,土壤盐分波动变化较大,在生育期内土壤盐分出现累积现象。从节水增产和抑盐方面考虑,灌溉定额3 900m3/hm2,灌水周期为5～7d的灌溉制度适合北疆农业生产。

| Abstract: | Under-plastic-mulch drip irrigation was studied through field experiments in arid areas of Xinjiang in 2009.The influences of various irrigation quotas and frequencies on water-salt distribution and cotton growth were analyzed.The results show that irrigations with a cycle of 5 days achieved the most appropriate moisture condition for cotton growth.With same irrigation quota,soil moisture increased by shortening irrigation cycle time.The higher irrigation frequency effectively reduced the salinity of root a... |
