Application of Farmland Productivity Evaluation Results in the Guidance to County Territory Agricultural Production
摘要
Abstract
On the basis of carrying out soil testing and formulated fertilization subsidy programs implementation and using farmland productivity evaluation results for years ,feasible utilization models of farmland productivity evaluation results were put forward:using soil nutrient testing data and field fertilizer experiment data of farmland productivity evaluation results ,the technical index system of soil testing and fertilizer recommendation of grain,vegetables and staple crops were established;farmland productivity evaluation results were also used to put forward suitable planting district ,soil type,soil nutrient,major evaluation factor and modified direction of different crops;using yield regression equation of the technical index system of soil testing and formulated fertilization ,yields of staple crops were estimated.Therefore ,through using the soil available nutrients test data and spatial data from soil fertility evaluation system ,usable range of crops fertilization index system was extended ,operability and intelligent degree were increased;using fertilization mathematical model from the crops fertilization index system ,target yield of crops can be estimated through soil fertility evaluation system,accuracy of evaluation content of soil fertility evaluation system was also improved.关键词
