摘要
渗水膜覆盖比普通膜覆盖具有较好的渗水、保水、保温和增产作用。本试验采用渗水膜覆盖、普通膜覆盖和不覆盖三种处理对谷子进行了研究。结果表明:全生育期内渗水膜覆盖较普通膜覆盖各土层土壤含水量平均增加1个百分点,较对照增加1.05个百分点;渗水膜覆盖较普通膜覆盖平均增温0.94℃,最高增温为1.4℃;与对照相比,渗水膜覆盖平均增温2.92℃,最高增温为4.2℃;采用渗水膜覆盖,谷子产量较普通膜覆盖增加27.7%,较对照增加34.2%。
The performances on soil water, temperature and yields covered by water-osmosis plastic membrane are the best of the three seeding ways. The experiment's results showed that by using water-osmosis plastic membrane the soil moisture content increased 1 percent, the soil average temperature increased 0.94℃ during the whole foxtail millet growth period, and the yield increased 27.7 percent in contrast with covering common plastic membrane. The soil moisture content increased 1.05 percent, the average soil temperature increased 2.92℃, and the yield increased 34.2 percent than that of the CK. The highest amount of soil temperature which was mulched with the water-osmosis plastic membrane increased 1.4℃ and 4. 2℃ than that of the covering common plastic membrane and CK.
