Standardization of crop irrigation using the agrohydrological characteristics, such as texture, bulk density, soil moisture under the lowest water capacity and wilting moisture is investigated .
用土壤的农业水文学特征，如土壤质地、土壤容量、最低田间含水量和萎蔫下的土壤含水量对作物灌溉的规范化进行了研究。
But even in the best of conditions, it can be difficult to judge how much moisture a plant needs until it shows signs of stress: leaf drop, wilting, brown edges.
但是，即便在最好的情况下，也很难在植物出现了问题(如：掉叶子、打蔫、叶边枯萎)之前判断某个植物需要多少水。
The results were as the following:(1) In semi-arid region of the Loess Plateau, the soil moisture contents of forestland and wasteland were low, near to the wilting humidity.
结果表明：（1）黄土高原半干旱区不同树种林地及荒坡土壤含水量很低，接近于凋萎湿度。
The effects of wilting point, field capacity and initial amount of available soil moisture in root zone on soil moisture were positive.
凋萎湿度、田间持水量、整个根区初始土壤有效含水量对土壤水分影响为正效应；
The effects of wilting point, field capacity and initial amount of available soil moisture in root zone on soil moisture were positive.
凋萎湿度、田间持水量、整个根区初始土壤有效含水量对土壤水分影响为正效应；
