摘要
近年来,随着我国奶牛养殖数量和规模的不断扩大,大量的粪尿作为肥料被广泛的施用在农田里,奶牛正常的生理活动产生的大量气体(CO2和CH4)也被排放到了空气中,但是反刍动物生产中排放的这些废物却对土壤、空气和水造成了日益严重的污染,其中粪、尿和气体中的碳、氮、磷、钾元素引起的环境污染问题更是不容忽视。本文就以上存在的问题综述了奶牛生产中碳、氮、磷和钾对环境的污染,并从营养和饲养管理上提出相应的减排技术措施。
With the increasing of diary cows number in China, in cows production large quantities of the manure and urine as fertilizer are widely applied in the fields, and a great deal of the gases （CO2 and CH4）which are produced by normal physiological activities in dairy cows release in the air, but the waste has increasingly serious pollution to soil, air and water . And the elements carbon（C）,nitrogen, phosphorus （P）,and potassium （K） in the waste cause inevitable environmental destruction. The paper is a summary about pollution way of C, N, P, and K in ruminant production and how to reducing these components not to pollute environment, and for the emission reduction of C, N, P, and K, the paper suggest improving corresponding nutrient management measures accordingly.
