旱地谷子休闲期地膜覆盖垄作效应研究

Effects ot mulch and ridge plant on dayland millet field at fallow stage

摘要: 试验研究结果表明，休闲期地膜覆盖可使春雨秋用，有效增加土壤水分含量，提高谷子出苗率，促进谷子生理代谢，增产28．2% 以上。并讨论了谷子生理变化，为改进旱地谷子栽培技术提供了科学依据。

Abstract: The experimental results show that dryland millet with mulch at the fallow stage can make the spring rainfall used in Autumn．With the method，the moisture content of soil is effectively increased，the rate of seedling emergence of millet raised，the metabolism improved,and the yield increased by 28．2%．The millet physiological changes are discussed，which provided scientific basis for the millet cultivation in dryland．
