要想找出作物需水规律和建立正确的灌溉制度与灌溉技术,从而达到科学用水,改良土壤,提高单位面积产最的目的,必须进行土壤水分测定,了解土壤中的储水量.如何通过以干土重百分数表示的土壤含水率来计算一亩地的储水量呢?现介绍一个简单的方法,以供参考.B=w×P×H×XB代表土壤储水量(公方/亩),w代表含水率(占干土重的百分率),P代表容最,H代表深
In order to find out the law of crop water demand and establish the correct irrigation system and irrigation technology so as to achieve the purpose of scientific water use, soil improvement and per unit area production, soil moisture measurement must be conducted to understand the amount of water in the soil. Dry soil weight percentage of the soil moisture content to calculate the amount of water per acre it? Here is a simple method for reference. B = w × P × H × XB on behalf of the soil water storage (square / mu) w represents moisture content (% of dry soil weight), P represents the most content, H represents deep
