配方施肥技术是取得农作物高产的重要措施。笔者认为,优化配方施肥应包括两个方面,一是配方技术的优化,二是推广途径的优化。近年来,我们应用已建立的计算机管理的土壤肥料信息系统进行了两个优化的初步研究。现将研究结果介绍如下。 一、基本思路 (一)选择有效的服务手段 合理的肥料配方涉及到土壤的理化性状、作物的需肥特性、耕作方法、土壤的投入 Formula fertilization technology is an important measure to obtain high yield of crops. The author believes that optimizing the formula fertilizer should include two aspects, one is the optimization of formulation technology, the second is to promote the optimization of ways. In recent years, we conducted two optimized preliminary studies using the established computer-based Soil and Fertilizer Information System. Now the research results are as follows. First, the basic idea (A) select an effective means of service A reasonable fertilizer formula involves the physical and chemical properties of the soil, the fertilizer needs of the crop, farming methods, soil inputs
