一般NPK大量元素在作物产出的贡献率在0%-80%,中量元素贡献率在10%-20%,生物肥贡献率在0%-20%,可见矿物质肥是最基本的,其作用不可替代。从美、欧洲等地区的经验来看,他们对于肥料的使用是基测土配方,中国的这条路还会很长。如果中国希望正确使用氮磷钾,就需要依靠精准农业,通过对土壤的分析了解作物的生长情况,从而确定肥料、农药的使用量。
The contribution rate of general NPK elements in crop output is 0% -80%, the contribution rate of middle element is 10% -20%, and the contribution rate of bio-fertilizer is 0% -20%. It can be seen that mineral fertilizer is the most basic, Its role can not be replaced. From the experience of the United States, Europe and other regions, their use of fertilizers is based on soil testing and the road to China will be long. If China wants to properly use N, P and K, it needs to rely on precision agriculture to understand the crop growth through soil analysis to determine the amount of fertilizer and pesticide use.
