小麦/玉米间作是河西绿洲灌区主要间作模式,但传统间作和套种需水量大,使该地区水资源紧张.2010年在甘肃河西走廊石羊河绿洲灌区进行大田试验,研究传统小麦秸秆焚烧、秸秆翻还和秸秆立茬3种留茬方式对小麦/玉米间作作物籽粒产量、水分利用效率(WUE)和经济效益的影响.结果表明:与焚烧和翻还的籽粒产量相比,立茬小麦单作分别增加7.2%和5.1%,立茬小麦间作分别增加6.2%和5.1%,立茬玉米单作分别增加4.7%和2.5%,立茬玉米间作分别增加7.2%和3.3%;与焚烧和翻还的WUE相比,立茬小麦单作分别增加20.4%和16.2%,立茬小麦间作分别增加17.9%和14.6%,立茬玉米单作分别增加16.7%和10.9%,立茬玉米间作分别增加11.8%和17.0%.就单作小麦、单作玉米和小麦/玉米平均值而言,焚烧、翻还、立茬处理的纯收益分别为10946、11471和13454元·hm-2.从籽粒产量、水分利用效率和纯收益等方面考虑,立茬种植方式为甘肃省河西绿洲灌区小麦/玉米最佳种植模式. Wheat / corn intercropping is the main intercropping mode in Hexi Oasis irrigated area, but the water demand of traditional intercropping and interplanting is large, which makes the area very tense.In 2010, a field experiment was conducted in Shiyanghe Oasis Irrigation Area of ​​Hexi Corridor in Gansu Province to study the effects of traditional wheat straw burning, (WUE) and economic benefit of intercropping wheat / maize crops.The results showed that compared with the grain yield of incineration and reversion, Increased by 7.2% and 5.1%, respectively, with the increase of 6.2% and 5.1% respectively for stubble wheat intercropping, 4.7% and 2.5% for stubble corn and 7.2% and 3.3% for stubble corn respectively; Compared with WUE, the wheat single crop increased 20.4% and 16.2% respectively, the wheat intercropping increased 17.9% and 14.6% respectively, the standing crop increased 16.7% and 10.9% respectively, 11.8% and 17.0%, respectively.The net profits of incineration, reversion and stubble treatment were respectively 10946, 11471 and 13454 yuan · hm-2 for single crop of wheat, single crop of corn and average wheat / , Water use efficiency and net income considerations, legislation Planting way in wheat / corn Optimal planting pattern of Hexi oasis irrigation.
