盲目施肥、过量施肥现象在我国农村一直普遍存在,严重影响了耕地综合生产能力的提高,也制约着粮食增产、农民增收、农业增效和环境保护。摸清耕地土壤的养分状况、肥力状况、土壤退化状况、地力状况和耕地综合生产能力的状况,对提高农业综合生产能力,促进粮食增产、农民增收、农业增效具有重要意义,对于提高粮食单产、降低生产成本、提高肥料利用率、减少肥料浪费、保护农业生态环境、保证农产品质量安全、实现农业可持续发展具有深远影响。
Blind fertilization and excessive fertilization have been ubiquitous in our country’s rural areas, which has seriously affected the improvement of comprehensive productive capacity of cultivated land and also constrained the increase of grain output, peasants’ income, agricultural efficiency and environmental protection. To find out the status of soil nutrients, soil fertility, soil degradation, soil conditions and comprehensive productivity of cultivated land is important to improve the comprehensive productivity of agriculture and promote the increase of grain output, farmers’ income and agricultural efficiency. It is of great significance to improve the grain yield , Reduce production costs, improve fertilizer utilization, reduce fertilizer waste, protect the ecological environment of agriculture, ensure the quality and safety of agricultural products, and achieve sustainable development of agriculture have far-reaching impact.
