无土栽培不用天然土壤就可以种植作物。它可以在沙漠、石山等一切不适宜于一般农业耕作的地区进行。但它必须将植物需要的13种元素都配制成营养液,对作物进行正确的灌溉,才能生长良好,配制的营养液全部是无机的。现在世界上的农业是向有机生态方面发展,这里介绍无土栽培专用有机肥的生产方法。 现代有机肥生产,与传统用人粪尿直接灌溉蔬菜等作物不同,后者容易有病虫害。全国各地都有许多大型养鸡场,几万只、几十万只甚至百万只的鸡场
Soilless cultivation crops can be planted without natural soil. It can be done in areas such as deserts and rock hills that are not suitable for general farming. But it must be the plant needs 13 kinds of elements are formulated into nutrient solution, the right crop irrigation, to grow well, all prepared nutrient solution is inorganic. Nowadays agriculture in the world is developing towards organic ecology. Here we introduce the production method of organic fertilizer for soilless cultivation. Modern organic fertilizer production, unlike the traditional irrigation of vegetables and other crops with human excrement, which is prone to pests and diseases. There are many large chicken farms throughout the country, tens of thousands, hundreds of thousands or even millions of chicken farms
