在新疆土壤中,磷、钾元素比较丰富,氮素与有机质则非常缺乏.这是新疆目前农业生产中急待解决的重要问题之一.为此拟根据有关资料,对此问题及解决途径加以探讨.一、新疆土壤农业化学性质的主要特点新疆耕地土壤农业化学性质的主要特点是:氮素含量甚少,一般耕地土壤含氮量约为0.01—0.1%(干土重%),超过0.15%者甚少.表1为1956—1961年我们在新疆各调查时所采取的耕地土壤分析结果. In Xinjiang soil, phosphorus and potassium are abundant, and nitrogen and organic matter are very scarce, which is one of the most urgent problems to be solved in agricultural production in Xinjiang at present. Therefore, it is proposed to solve this problem according to the relevant data First, the main characteristics of agro-chemical properties of soil in Xinjiang The main characteristics of agro-chemical properties of cultivated land in Xinjiang are: nitrogen content is very small, the average soil nitrogen content of about 0.01-0.1% (dry soil%), more than 0.15 Table 1 shows the results of arable land analysis from 1956 to 1961 during the surveys in Xinjiang.
