伊犁地区处于天山西部的山间河谷盆地内,辖八县一市,有土地面积5.7万平方公里,耕地449.19万亩,自然条件优越,是新疆重要的农、林、牧业基地。为了摸清土壤底细,因地制宜地发展农业生产,现对地区土壤有效微量元素的含量及其分布规律进行初步探讨,以期作为因土施肥,合理施用微肥的参考。 一、土壤有效微量元素的含量 微量营养元素是指土壤中含量很低,植物需要量很少的一些化学元素。而有效微量元素的含量通常是判断土壤微量元素供应丰缺的指标。现以自治区土肥站暂定的分级标
Yili region is located in the mountain valley basin in the west of Tianshan, with jurisdiction over eight counties and one city. It has a land area of 57,000 square kilometers and a land area of 4,491,900 mu. It enjoys excellent natural conditions and is an important base of agriculture, forestry and animal husbandry in Xinjiang. In order to find out the soil fineness and develop agricultural production according to the local conditions, the content of soil available trace elements in the area and their distribution are discussed tentatively, which can serve as a reference for fertilizing the soil and using the fertilizer rationally. First, the soil content of trace elements Micro-nutrients is the content of soil is very low, the plant needs a small amount of some chemical elements. The effective content of trace elements is usually to determine the abundance of soil trace elements supply indicators. Now Tucheng Autonomous Region tentative grading
