摘要
根据1986-2002年逐年无机养分投入量与粮食产量的统计分析表明，随着农田无机养料投入的增加，粮食产量及土壤养分残存量随之提高，探明了无机氮磷钾的直接增产与互作增产的效应，明确了在高产栽培中氮磷兼施，以磷增氮的作用。根据1991-2006年106个点位土壤养分监测结果的聚类分析，将新乡市所辖9县市区的土壤划分为四大土壤养分不同类型区，提出了保持土壤肥力、实行农业可持续发展的建议，从土壤养分平衡状况对新乡市农业生产持续稳定的发展进行了讨论。
The food yield and nutrient residue quantity in soil rised with increase of inorganic fertilizer application quantity according to analyzing the statistical data of application quantity of soil nutrient and crop yield from 1986 to 2002, which indicates that applying N,P and K has the direct and interactive effect on crop yield increase and P fertilizer can improve N fertilizer effect on yield increase in the high yield cultivation. The soil of 9 counties and cities was divided into 4 soil nutrient types by the cluster analysis of soil nutrient monitoring results of 106 sites from 1991 to 2006. The paper puts forward the suggestion for preserving soil fertility and implementing agricultural sustainable development by analyzing the effect of soil nutrient balance condition on sustainable and stable development in agriculture production in Xinxiang city.
