摘要
在沈阳地区进行了残茬覆盖的试验,以传统翻耕为对照。结果表明,留茬覆盖与留茬不覆盖均具有明显蓄水保墒作用,可以有效地改善春播期和整个生育期的土壤水分状况,随着玉米的生长和雨季的到来愈发显著;两种处理都可以明显改善玉米农艺性状,提高产量8.98%～11.92%,节约用水5%以上,且可以提高水分利用效率15.81%～18.14%。
Residue cover experiment compared with traditional cultivation was conducted in shengyang,The result show that stubble mulch and stubble without mulch significantly improved the soil water storage capacity,effective improved water moisture during a period of spring sowing and maize growth.Along with growing of maize and rain season coming the advantage was prominent.Both character of maize and yeild were improve.The production had increased 8.98%～11.92%,exceeded 5% on saving water,and increased WUE 15.81～18.14 than traditional cultivation.
