随着我国人民生活水平的提高,畜禽产品需求量在不断增加,生产规模也在不断扩大,特别是城市“菜篮子工程”的实施,我国畜禽养殖业得到迅猛发展。现代化封闭型养殖技术,促使畜禽养殖业向集约化方向发展。目前我国畜禽养殖的集约化程度已发展到相当高的水平,其产生的大量污水、粪便在一些地方成为重要的污染源,甚至成为一些河流、湖泊污染的“元凶”。“猪粪是个宝,庄稼少不了”,曾经是农家肥的畜禽粪便真的成了污染“元凶”吗?在广西兴业县情况完全不是这样。 With the improvement of people’s living standards in our country, the demand for livestock products is on the increase and the scale of production is also constantly expanding. Especially in the implementation of urban “vegetable basket project”, the livestock and poultry farming industry in our country has been developing rapidly. Modern closed culture technology, prompting livestock and poultry farming to the direction of intensive development. At present, the intensity of livestock and poultry farming in our country has developed to a very high level. The large amount of sewage and manure produced in these areas have become an important source of pollution in some places and have even become the “culprit” of some river and lake pollution. “Pig manure is a treasure, and crops are indispensable.” Was the livestock manure that used to be a farm manure really become the “culprit” of pollution? In Xingye County, Guangxi, this is not the case at all.
