1概况 我国肥料施用总体上还处于以速效性肥料分次施用为主体的施肥阶段,应用缓释性肥料和专用复合肥且采用一次性施肥技术是从根本上解决我国目前施肥方法现状的唯一途径。我国对复合肥的研究虽不算晚,但应用于农业生产却一直呈现徘徊不前的局面。进入九十年代,经各级部门的共同努力,国产复合肥生产工艺日臻完善,产量逐年上升,应用效果日益明显,应用面积也因此不断扩大。
1 Overview Fertilizer application in general is still in the fast-acting fertilizer sub-application as the main fertilizer stage, the use of slow release fertilizer and special fertilizer and the use of disposable fertilization technology is the fundamental solution to the current situation of China’s current fertilization methods the only way . Although the study of compound fertilizer in China is not too late, it has been stagnant for agricultural production. Into the nineties, with the joint efforts of departments at all levels, the domestic compound fertilizer production technology is improving, the output increased year by year, the application effect is increasingly obvious, the application area is also expanding.
