STUDY ON UNDERDRAINAGE OF CATTLE PADDOCK

牛围场排水不足研究

基本信息

项目摘要

Always the paddock soil is mudded by excreta that cows exhausted and the kneading returns an drain are always defective in dairy farmers'paddock now. And, the influence with a badness for cows'health and milking defective drain of the paddock is given.The under drainage was constructed to two dairy farmers'paddocks to do the under drainage improvement of such paddocks in November, 1992.We investigated these two dairy farmers'paddocks as an investigation target for five years before and after construcion about the moisturs content of soil, the three phases of soil, and the static corn penetration of soil.As a result, the moisture content of the paddock soil decreased remarkably after having constructed the under drainage. Moreover, the rate of the gas phase and the rate of the solid phase after constructing the under drainage and the rate of the liquid phase has decreased in the three phases of paddock soil. The improvement of drain in this paddock rose bearing capacity and facilitated walking of cows of ground power of the paddock soil in the paddock. As for the construction of the under drainage to dairy farmers'paddock, it has been understood to be useful for the improvement of the drain of the paddock and to improve cows'life environments according to the result.
奶牛筋疲力尽的排泄物使围场土壤变得浑浊不堪,现在奶农的围场里,捏回排水沟总是有瑕疵的。1992年11月对两个奶农围场进行了地下排水改造,并以此为调查对象,对这两个奶农围场在建设前后5年的土壤含水率、土壤三相、土壤静态玉米入渗情况进行了调查,结果表明,排水后围场土壤含水率显著下降。此外,围场土建造后的气相比率、固相比率和液态比率均有所下降。该围场排水能力的改善,提高了围场土壤的承载能力,方便了奶牛在围场内的走动。根据研究结果,对奶农围场进行地下排水的施工,对改善围场排水,改善奶牛的生活环境有一定的作用。
