优质的耕地土壤是长期发育或多年培育的结果。除了增加有机质外,在生产上,还必须根据地力的变化,对耕地质量进行动态管理,如运用测土配方施肥,合理轮作换茬,土壤改良调理等多种技术措施,为土壤“增肥”。1.测土配方施肥测土配方施肥是以土壤测试和肥料田间试验为基础,根据作物的需肥特性、土壤的供肥能力和肥料效应,在合理施用有机肥的基础上,确定氮磷钾以及其他中微量元素的合理施肥量及施用方法,以满足作物均衡吸收各种营养,
High-quality arable land is the result of long-term development or years of cultivation. In addition to increasing organic matter, the quality of arable land must also be dynamically managed according to changes in soil fertility. For example, soil testing and fertilizer application, crop rotation and crop improvement, ". 1. Soil Testing and Fertilization Soil Testing and Formula Fertilization is based on soil testing and fertilizer field tests. Based on the fertilizer-needed characteristics of crops, soil fertility and fertilizer effect, on the basis of reasonable application of organic fertilizers, determine the content of NPK And other trace elements in a reasonable amount of fertilizer and application methods to meet the balanced crop absorption of various nutrients,
