| 摘 要： | 据１９９２－１９９３年大田试验结果，分析了不同时期麦秸覆盖对夏玉米生和发育和产量的影响，结果表明，麦秸覆盖后对夏玉米的产量有一定的影响，在１９９２年的降雨年型下，麦秸覆盖对夏玉米的产量有提高作用，在１９９３年的降雨条件下，麦秸覆盖数量在不超过９．０ｔ／ｈｍ＾２时对夏玉米的产量有提高作用，超过时则出现夏玉米产量低。从大田试验中采集的麦秸样品的水提液发芽试验中得出，麦秸中水溶性毒素物质随着降雨淋入土壤

| Abstract: | Wheat straw mulching effects the yield of corn. The yield of corn mulched with wheat straw increased in 1992, when it was a rainy year. In 1993, when the mulching straw weighed less than 9. 0 tons/ha the yield of corn also increased, while corn yield decreased when the mulching straw weighed over 9. 0 tons/ha.A germinative test was carried out with water extract of wheat straw samples collected from the field, which indicated that the water-soluble toxic substances in wheat straw could get into the soil as washed by rain, and its toxity could last more than 3 months. |
