| 摘 要： | 该文以浦江县近10a作物种植结构变化为基础,以农户农业生产调查为样本数据,运用TechnoGIN模型对浦江县近十年的经济作用养分投入情况分析,对照经典试验数据得出经济作物养分投入已严重过剩,仅浦江县2006年水果、蔬菜和苗木的养分过剩量分别占浦江县该年氮肥、磷肥总投入量的35.2%和28.6%,养分利用效率均低于20%。因此,如何规范经济作物的农业养分投入不仅是减少生产成本增加农业经济效益的重要途径,更是减少农业面源污染的的迫切需要。

| Abstract: | Based on the crop nutrient input of Pujiang county in recent ten years,regarding farmer investigations as samples,with means of TechnoGIN model,contrasting with classical testing data,the nutrient inputs of many kinds of land use types were analyzed.The results showed that there was a serious surplus of nutrient input of economic crops. The ratio of superfluous nutrient of fruit,vegetable and seedling and total amount of nitrogen and phosphate was 35.2% and 28.6%in Pujiang county in 2006.Nutrient use effici... |
