1974-1975年,我们对冬小麦进行施磷肥试验,结果是:在缺磷地块亩施30-120斤过磷酸钙,增产3.7-16.9％,在这个范围内,用量越大,产量越高。据王亚良种场等11个点试验,氮、磷单施和配合施用,均显著增产。如西陈大队在含磷0.9ppm、含氮12.9ppm的地块,亩施氮吧60斤,比不施的增产17.8％;亩施磷肥70斤的增产68％;氮、磷配合施用的增产92.8％。
From 1974 to 1975, we conducted a phosphate fertilizer test on winter wheat. As a result, 30-120 kg of superphosphate per mu of phosphorus-deficient plots increased yield by 3.7-16.9%. Within this range, the higher the dosage, the higher the yield. According to Wang Ya-liang and other field trials 11 points, nitrogen and phosphorus single application and with the application, were significantly increased. Such as the West Chen brigade phosphorus 0.9ppm, 12.9ppm of nitrogen plots, 60 kg of nitrogen fertilizer Mushu than 17.8% increase in yield; 70 kg of phosphorus fertilizer yield increase of 68%; nitrogen and phosphorus with the application of yield 92.8%.
