发展精准生态农业的基础之一是测土配方施肥,论述选用腐植酸作为测土配方肥有机质的原因及质量指标,水溶性腐植酸只是作物吸收的先决条件,其必备条件是小分子量。同时指出腐植酸活化土壤功能同腐植酸的速效部分的互补关系,否定了凡是腐植酸都可在肥料上使用的观点。
One of the foundations of the development of precision eco-agriculture is soil testing and fertilizer application. The reasons and quality indexes of selecting organic fertilizer for soil testing and fertilizer are discussed. Water-soluble humic acid is only a prerequisite for crop absorption, and its prerequisite is small molecular weight. At the same time pointed out that the humic acid activated soil with humic acid fast-acting part of the complementary relationship, denied that all humic acid can be used in the fertilizer point of view.
