通过9年新乡市土壤养分监测，对有机肥与化肥的投入量及农作物产量等有关资料的统计分析，明确了随着耕地养分投入的逐渐增加，农作物产量及土壤养分随之提高，有机肥在培肥土壤持续增产中的重要地位。探明氮、磷肥对作物增产的直接效应与间接效应，在高产栽培中氮磷兼施，以磷增氮的互作增产作用。并从土壤养分盈余量的信息反映，对新乡市农业生产持续稳定发展的前景进行了展望。
Through 9 years of soil nutrient monitoring in Xinxiang City, the statistical analysis of the inputs of organic fertilizer and chemical fertilizer and the yield of crops shows that with the gradual increase of input of cultivated land nutrients and the increase of crop yield and soil nutrients, Soil fertility continued to increase production in an important position. The direct and indirect effects of nitrogen and phosphorus fertilizers on crop yield increase were proved. Both nitrogen and phosphorus were co-applied in high-yielding cultivation, and the interaction between phosphorus and nitrogen increased yield. And from the information of soil nutrient surplus, it reflects the prospect of sustainable and stable development of agricultural production in Xinxiang City.
