科学施肥是发展高产高效农业的重要技术措施,探索各种生产条件下的经济最佳施肥量不仅能最大限度地提高产投效益,而且可避免施肥过量和不同肥料元素比例失调所造成的相对过剩,从而减少资源浪费和化肥流失对农业环境的污染,有效地保持和提高土壤肥力,促进农业的持续稳定发展。肥料效应函数法是探索最佳施肥量的重要田间试验方法之一,虽然该法设备试验小区较多,调查、处
Scientific fertilization is an important technical measure to develop high-yield and high-efficiency agriculture. It is not only possible to maximize the economic benefits of production but also to avoid the excess of fertilizer and the relative surplus caused by the imbalance of different fertilizer elements under various production conditions So as to reduce the waste of resources and the pollution of agricultural environment caused by the loss of chemical fertilizers and effectively maintain and improve soil fertility and promote the sustainable and stable development of agriculture. Fertilizer effect function method is to explore the best fertilization of an important field test method, although the law equipment test plot more investigation, office
