小麦精确施氮技术研究

Technique of Precision Nitrogen Fertilizer in Wheat

在低肥力沙壤土上精确施用氮肥可有效增加小麦产量,提高肥料的当季利用率,降低施肥成本。试验结果表明,精确施氮有利于提高小麦单位面积有效穗数和每穗实粒数,使得小麦增产效果显著。

Application of precision nitrogen fertilizer in low fertility sandy loam soil can increase wheat yield, improve fertilizer utilization rate, and reduce the cost of fertilization. The test results show that the precise application of nitrogen fertilizer can improve efficient panicle of wheat unit-acreage and grain number of per panicle, increase the yield of wheat.
