作物对微量元素的需求虽然很少,但微量元素对作物的生长发育来说却是不可缺少的。由于有机肥施用量减少,微量元素不能及时补充,形成了土壤微量元素日益亏损的局面,致使土壤中微量元素可吸收量呈逐年下降趋势,有的甚至出现严重不足,制约了小麦产量的进一步提高。本试验通过分析硫酸锌和硫酸锰在小麦上的应用效果,以期为昭苏县小
Although there is little demand for trace elements in crops, trace elements are indispensable to crop growth and development. Due to the decrease of organic manure application, the trace elements can not be replenished promptly, forming an increasingly deficient situation of soil trace elements. As a result, the trace element absorption in soil shows a declining trend year by year, and some even have serious deficiencies, which restrict the further increase of wheat yield . This experiment by analyzing the application of zinc sulfate and manganese sulfate in wheat, with a view to Zhaosu County small
