洛阳地区冬小麦保护性耕作节水效应研究

摘要

Through years of testing and data monitoring, different water treatments were set up in measuring pit under the canopy, and the effects of no cover and straw mulch on the water consumption characteristics, yield and water use efficiency of winter wheat were studied. As indicated by the results, the total water consumption amount of no cover and straw mulch differed insignificantly, the straw mulch also produced obvious influence on the yield and water use efficiency of winter wheat.%通过多年试验及数据监测,在防雨棚下的测坑中设置不同的水分处理,研究无覆盖与秸秆覆盖对冬小麦耗水特征、产量以及水分利用效率的影响.结果表明,试验区冬小麦生育期间,覆盖与不覆盖处理间总耗水量差异明显,但不显著；秸秆覆盖对冬小麦产量和水分利用效率也存在明显的影响.
