在农作物的产量形成中,土壤肥力起着重要的作用,地力产量所占比例约在70%左右.产量越高,地力产量的比重越大.经过四年研究,获得了用地力产量估测目标产量的回归方程;同时也获得了用有机质、碱解氮和有效磷等三个土壤养分性状估测地力产量的回归方程.应用这两个方程对小麦的目标产量进行估测,结果与实际产量比较符合,可用于测土施肥技术中的施肥推荐模型. In the formation of crop yield, soil fertility plays an important role, and the proportion of geo-productivity is about 70% .The higher the yield, the greater the proportion of geo-production.After four years of research, The regression equations of soil fertility were obtained by using three soil nutrients such as organic matter, available nitrogen and available phosphorus.The estimated yield of wheat was estimated by using these two equations and the results were compared with the actual yield More in line with the fertilization technology can be used for soil fertilization recommendation model.
