前言一九七九年我们在黑龙江省粘土与砂土土壤上进行了许可喷灌强度与土壤入渗能力的试验。其试验目的,试验方法参看《黑龙江水利科技》一九七九年增刊高歌阳、刘希贤文章。苏联×0.1提出土壤性质、喷水定额、喷灌强度和喷洒雨滴粒径关系方程,即P=m(i~(1/2))e~(0.51)。式中:P——土壤无压入渗指标,它描述土壤性质和前期含水量对土壤入渗能力的影 Preface In 1979, we conducted a trial of permitted sprinkler irrigation intensity and soil infiltration capacity in clay and sandy soils of Heilongjiang Province. The purpose of the test, test methods, see “Heilongjiang Water Conservancy Technology” supplement 1979 Gao Yang, Liu Xixian article. The Soviet Union × 0.1 proposed soil properties, water quota, sprinkler irrigation intensity and spray raindrop particle size equation, namely P = m (i ~ (1/2)) e ~ (0.51). Where: P-- soil infiltration pressure indicator, which describes the nature of soil and water content of the early infiltration of soil
