通过近几年对十三师3种主要土壤类型(砂土地、壤土地、新垦区)的常量元素含量进行测定,结果表明:当地棉田的土壤养分含量丰缺不一,差异较大,砂土地棉田缺氮状况较普遍;壤土地氮、磷都比较缺乏;新垦区缺氮缺磷情况比较严重。 In recent years, the thirteen division of the three main soil types (sandy land, loamy land, reclamation area) of the major elements were determined, the results showed that: the local cotton soil nutrient abundance varies widely, the difference between sand Nitrogen deficiency is more common in cotton fields; N and P in the loam soil are relatively scarce; N and P deficiency in the newly reclaimed land is more serious.
