摘要
采用有机硅喷涂、拍光压实及自然坡面3种集流措施收集雨水,研究在不同集流措施下种植带内水分动态变化,以及对作物生长发育的影响。结果表明,有机硅喷涂措施在作物生长季节能大大提高种植带内的土壤含水量和集水量。
The effects of catchments methods on water potential and growth of crop planted in sloping fields were studied in loess plateau of shannxi povince. The different way to rainwater catchments, for example spraying the new-type macromolecule organic silicon on the tamped slope surface, the tamped slope surface and the nature slope surface, under the slope, to determine soil water and growth of crop at timing. The experiments showed that the compacted surface soil slope with organic silicon chemical treatment catched much rainwater harvesting , to promote the crop growth. The mass was 1.1 times as the compacted surface soil slope, was 1. 5 times as the nature slope.
