土壤水分测定方法虽种类繁多,却不够简便和可靠,特别是深层土壤水分测定更难于找到一种合适的方法。近年来有人通过土壤水分模型来计算,作者曾根据农田水量平衡制订了一种计算方法。B.C.BisWas和S.K.Dasgupta(1979)、和(1982)以及(1982)也曾进行过这方面的研究,提出根据某一有代表 Although a wide range of soil moisture determination methods, but not simple and reliable enough, especially in deep soil moisture determination is more difficult to find a suitable method. In recent years, some people calculated by soil moisture model, the author has developed a calculation method according to farmland water balance. B.C.BisWas and S.K.Dasgupta (1979), and (1982) and (1982) have also conducted research in this area, proposed according to a representative
