一、前言 随着三高农业的发展,农民对科学种田有了充分认识,肥料生产也显得更加重要。根据土壤中各种营养元素的丰缺状况和农作物需肥规律进行配方施肥,是发达国家的施肥方法。各地土壤差异较大,各种作物的需肥比例不同,这就要求复混肥的生产方法也不同。目前,国内的低含量复合肥(N、P、K总量小于30％)和进口复合肥(N:P:K=15:15:15)均不能很好地适应配方施肥的要求。为了使测
I. Introduction With the development of the three high agricultural areas, farmers have fully recognized the scientific farming and fertilizer production is even more important. According to the abundance and shortage of various nutrients in the soil and crop fertilizer requirements of the formula fertilization, fertilization methods in developed countries. Large differences in soil around the various crops need to be different proportions of fertilizer, which requires the production of compound fertilizer is also different. At present, the domestic low-content compound fertilizers (N, P, K total less than 30%) and imported compound fertilizers (N: P: K = 15:15:15) are not well adapted to the requirements of the formula fertilization. In order to make measurements
