摘要
通过对永城市18个监测点1500个土样检测数据进行分析,依据河南省耕地土壤养分分级标准,对土壤肥力进行评价,摸清了全市农田N、P、K等养分状况及养分变化,建立了主要农作物的施肥最佳施肥指标。
Based on the analysis of 1500 soil samples from 18 monitoring stations in yongcheng city,soil fertility was evaluated according to the classification standard of farmland soil nutrients in Henan Province.The nutrient sta?tus of farmland N,P,K and its influence on soil nutrients change were found out,and the best fertilization index for main crops was established.
