淮安市高标准农田养分现状与培肥建议

Soil Nutrient Status and Fertilizer Recommendations for Huai'an High Standard Farmland

为提升淮安市高标准农田的地力,对全市高标准农田的土壤养分状况进行分析研究。结果表明,全市高标准农田土壤养分以中等、较丰富、较缺级别为主,土壤养分总体水平不高,并且近6 a来增幅缓慢;不同类型土壤的养分差异较大。

In order to promote the soil fertility of high standard farmland in Huai＆#39;an city, soil nutrient status of the city＆#39;s high standard farmland were analyzed. The results show that the soil nutrients of the high standard farmland ranges from being medium to being relatively rich and to the level of insufficiency, the overall level of soil nutrient is not high, with a slow increase rate for the past 6 years;and there is a large difference between various soils in nutrients.
