多年来的试验结果一致证明,对淮南、淮北的低产麦田实行氮、磷素肥料配合使用的施肥方法,确实能迅速提高小麦产量.肥西县园林公社瘠薄麦田采用氮、磷素肥料配合施用,小麦单产成倍增长.利辛县柳西大队低产麦田采用此法,单产也是成倍增长.这项试验虽因文化大革命而中断,但其增产作用是可以肯定的.现将过去五年多的试验结果,简要综述如下: Test results over the years have consistently proved that the application of nitrogen and phosphorus fertilizers to low-yielding wheat fields in Huainan and Huaibei can indeed increase the yield of wheat rapidly. The barren wheat fields in the garden commune of Feixi County are applied with nitrogen and phosphorus fertilizers, Wheat yield doubled .Lixin CountyLow West Brigade low yield wheat fields using this method, yield is doubled .Although the experiment was interrupted due to the Cultural Revolution, but its role in increasing production is affirmative.Currently over the past five years The test results, a brief summary is as follows:
