宜昌市新增蔬菜基地土壤肥力状况及培肥措施

摘要

in Yichang city added vegetable base of soil fertility status of analysis results indicates that：Yichang city,now the new vegetable bases soil acidity is more appropriate for vegetable growth,but with lower organic matter content,especially for xiaoting higher soil organic matter content in most of the village,the shop lack general phosphorus,most lacking alkaline nitrogen content,quick~acting potassium content does not equal,and very different,both lack of or very soil and potassium~rich soil.Soil fertility measures for deep soil,break the rice soil plough bottom;applying organic fertilizers,improving its permeation properties;selective planting,achieve the goal of gradually building;guest soil mixed with sand soil improvement,improve soil texture.%对宜昌市新增蔬菜基地的土壤肥力状况作了分析,结果表明：目前宜昌市新增蔬菜基地土壤酸碱度（pH值）较适宜蔬菜的生长,但有机质含量普遍低下,尤其以猇亭高家店村的土壤有机质含量最为缺乏;普遍缺磷,碱解氮含量大部分缺乏,速效钾含量不均等,并且差异极大,既有缺乏或极缺乏的土壤,又有富钾的土壤。提出了土壤的培肥措施：深耕翻地,打破水稻土的犁底层;增施有机肥,改善其通透性能;选择性种植作物,达到逐步培肥地力的目的;利用掺砂客土进行土壤改良,改善土壤的质地。
