摘要
为了准确掌握测土配方施肥田块氮、磷、钾肥不同配方施肥对陈仓区冬小麦生长及产量的影响,进行了陈仓区冬小麦肥料利用率试验.试验结果表明,在小麦主产区,施入纯氮13 kg/667 m2、五氧化二磷7 kg/667 m2,氧化钾3 kg/667 m2,总体小麦越冬期、拔节期、收获期生长健壮,表现较好.尤其在小麦抗条锈病、抗倒伏性方面,氮磷钾区较无氮区、无磷区田块能力强.
Abstract
In order to accurately understand the effects of different formulations of nitrogen,and to further understand the nitrogen,phosphorus and potassium fertilizer uptake and fertilizer utilization rate of wheat plants and grains,the fertilizer utilization rate exper-iment of winter wheat in Chencang District was carried out.The results showed that in the main wheat producing areas,13 kg/667 m2 of pure nitrogen,7 kg/667 m2 of phosphorus pentoxide and 3 kg/667 m2 of potassium oxide were applied,and the overall wheat growth was robust during the overwintering period,jointing period and harvest period.Especially in the resistance to stripe rust and lodging of wheat,the field capacity of N,P,K region is stronger than that of N,P,K and P free region.
