喀什蔬菜基地土壤养分分析与评价

Analysis and Evaluation of Soil Nutrients in Vegetable Base for Kashgr

以南疆喀什地区荒地乡蔬菜基地土壤为研究对象,通过野外调查取样和室内试验的方法,采用全国第二次土壤普查养分分级标准为依据研究土壤中养分分布特征。研究结果表明:有机质平均含量为17.2 g/kg,53.2%的土壤呈缺乏状态;全磷平均含量0.2 g/kg,82.3%的土壤呈极度缺乏状态;碱解氮平均含量40.7 mg/kg,61.4%的土壤呈较缺乏状态;速效磷平均含量8.5 mg/kg,73.3%的土壤呈中等状态;速效钾平均含量177.1 mg/kg,69.5%的土壤呈较丰富状态。

Taking vegetable base soil in southern Xinjiang Kashgar area as the research object,through field investigation and sampling and laboratory test,the method of the second soil census nutrient classification standard based on the research of soil nutrient distribution was used for characteristics. The research results showed that the organic matter content was 17. 2 g / kg on average,53. 2% of the soil was lack of state. Total phosphorus content was 0. 2 g / kg on average,82. 3% of the soil was in extreme lack of state. Alkaline hydrolysis nitrogen content was 40. 7 mg / kg on average,61. 4% of the soil is lack of state. Available p content was 8. 5 mg / kg on average,73. 3% of soil of moderate state. Rapidly- available potassium content was 177. 1 mg / kg on average,69. 5% of the soil was rich.
