摘    要:针对目前农业生产中存在的施肥增产效应下降问题,研究了磷肥用量对冬小麦养分、氮磷钾和干物质积累及产量的影响,以期为高产高效施肥提供依据.在黄土高原旱地进行田间试验,设不施磷,施磷P2O5 50kg/hm2(不足)、P2O5 100 kg/hm2(适量)和P2O5 150 kg/hm2(高量)4个水平,在不同生长期采样测定...

Abstract:In order to explain the phenomenon of the decrease of crop yield-increasing effects caused by over fertilizer application commonly existing in present agricultural production in China,this paper focused on the effects of P rates on N,P,K and dry matter accumulation and grain yield of winter wheat.A field experiment was carried out with winter wheat as test crop and at P rates of 0,50(deficient),100(optimum) and 150(excessive) P2O5 kg/hm2.The aboveground part of the crop was sampled at different stages to es...
Keywords:P rates  winter wheat  yield  water  nitrogen  phosphorus  potassium
