化肥深施机械化技术是通过机械将化肥按当地农艺要求,施于土壤表层以下6～15cm土层中,此技术是我国“七五”期间开始推广的一项较成熟的节本增效工程技术。目前,此技术主要用于旱田作物。 1.化肥深施的方法 (1)底肥深施。底肥深施机械化技术与土壤耕翻结合起来,目前有两种方法:①边耕翻边将化肥施于犁沟内;②先撒肥后耕翻,在耕地过程中,将地面化肥深翻于犁沟底面 Fertilizer deep mechanized technology is through mechanical fertilizers according to local agricultural requirements, applied to the soil surface layer 6 ~ 15cm below the soil, this technology is China “75 ” period began to promote a more mature cost-effective Engineering Technology. At present, this technology is mainly used for dryland crops. 1. The method of fertilizer application (1) deep application of base fertilizer. At the end of fertilizer application mechanized technology and soil tillage combined, there are two ways: ① edge flanging the fertilizers in the furrows; ② first tillage fertilizer, in the process of arable land, the ground fertilizer deep turn in Furrow bottom
