小麦配方施肥技术的研究

On Technique of Appling Fertilizer by prescription on Wheat

本文选砂姜黑土和潮土为供试土样，在小麦配方施肥中测定其肥力，结果提示，低肥田施氮肥，砂姜黑土为１８０．５ｋｇ／ｈｍ２、Ｐ２Ｏ５为８２．５ｋｇ／ｈｍ２；潮上的Ｎ为９６．５ｋｇ／ｈｍ２、Ｐ２Ｏ５为９０．０ｋｇ／ｈｍ２．中肥田中，砂姜黑土Ｎ为１３５．０ｈｍ／ｈｍ２、Ｐ２Ｏ５为３５．５ｋｇ／ｈｍ２；期土的Ｎ为１３９．３ｋｍ／ｈｍ２、Ｐ２Ｏ５为９０．０ｋｇ／ｈｍ２．高肥田中，砂姜黑土Ｎ为７８．０ｋｇ／ｈｍ２、Ｐ２Ｏ５为８１．０ｋｇ／ｈｍ２；潮土的Ｎ为１０６．０ｋｇ／ｈｍ２、Ｐ２Ｏ５为７６．５ｋｇ／ｈｍ２．

The paper reports the test of the appling fertilizer by prescription on wheat in the gravel black soil and the aqult soil. In the poor land, nigrogen and phosphorus pentoxide is 180.5kg/hmz, 82.5kg/hm2 in the gravel black soil sespecxively,is 96.5kg/hm2,90.0kg/hm2 in the agult sill respectively.In the genoral land, nitrogen and phosphorus pentoxide is 135.0kg/hm2, 35.5kg/hm2 in the gravet soil respectively,is 139.5kg/hm2,90.0kg/hm2 in the agult soilrespectively.In the fertile land, nitrogen and phosphorus pentoxide is 70.8kg/hm2, 81. 0kg/hm2 in the gravel black soil respecxively,is 106.0kg/hm2,76.5kg/hm2 in the aqult soil respectively.
