萎蔫系数 meaning in English
wilted coefficient
wilting coefficient
Examples
- Results showed : ( 1 ) if the proportion of water in the soil is lower than wilting coefficient , and if irrigating water is very little , ( irrigating water is spreading horizontally and vertically ) the relationship between the horizontal width ( x ) and the ? rtical depth ( y ) is remarkable . the equation is y - 0 . 02 12x2 + l . 8546x - 17 . 88 . the related coefficient is r = 0 . 9350
结果表明： （ 1 ）在土壤含水量低于萎蔫系数的干燥条件下，进行微量穴滴灌，滴灌点土壤湿润面直径x与最大垂直面渗透深度y呈显著相关，数学模型为： y = - 0 . 0212x ~ 2 + 1 . 8546x - 17 . 88 ，相关系数r = 0 . 9350 （ 2 ）在微量补水灌溉情况下，只有灌水量大于4000ml /穴，才能使滴灌水渗透到20cm以下土层，达到作物根系集中层，否则水分很难被作物吸收，造成滴灌水的浪费。
