在各处理组合中,以沿等高线种植、浅耕、净作玉米的经济性状最优,小区产量达21.62千克/40平方米,而顺坡种植、翻耕、净作的经济性状最差,小区产量仅12.78千克/40平方米。收藏指正
4.Abstract: In accordance with the problems in the system of well storing rainfall at present,based on the experiments of artificial simulating rainfall,and assistance with the measures of natural rainfall,the relationships among the surface runoff yield,silt concentration,catching runoff efficiency and the material of surface,slope gradient,rainfall intensity are analysed systematically.Then,the best slope gradient and material of surface are chosen,in condition of which surface rainfall yield is the largest and silt concentration is the smallest.This is a beneficial study for the practical use of the rainwater catchment plot in furture.
文摘:针对当前旱井集雨系统存在的问题，利用人工降雨试验，并辅以天然降雨观测，系统分析了旱井集流区的产流量、含沙率、集流效率与下垫面材料、坡度、降雨强度的关系，进而选出了最优坡度及最优下垫面材料，为今后旱井集流区的应用研究做了有益的探讨。收藏指正
5.The research for soil permeability and surface runoff in Huangjia-Er- cha small watershed in Xiji county, Ningxia, was done by means of arti- ficial precipitation and runoff-plot testing method,which showed that pri- mary factors affecting soil permeability are land utilization, slop, soil moisture, total porosity of soil and rain intensity.
运用人工模拟降雨和径流小区试验方法,研究了宁夏西吉县黄家二岔小流域的土壤渗透性能。 结果表明,影响土壤渗透性能的主要因子是土地利用方式、地面坡度、土壤含水率、土壤总孔隙度和雨强。收藏指正
