不同土壤肥力下强筋小麦适宜施氮量的研究

Study on optimum amount of nitrogen for strong gluten wheat under different soil fertility conditions

在高肥和中肥地力条件下 ,研究了不同施氮量对强筋小麦济南 17号的籽粒品质和产量的影响 ,根据品质、籽粒产量、蛋白质产量、籽粒产量氮素生产效率和蛋白质产量氮素生产效率综合分析 ,在高肥和中肥土壤条件下 ,济南 17号高产、优质、高效的施氮量分别为每 6 6 6 7m2 12～ 16kg和 12kg。

Effects of different amounts of nitrogen on grain quality and yield for strong gluten wheat were studied under high and moderate soil fertility conditions According to quality, grain yield,protein yield,nitrogen producing efficiency of grain yield and nitrogen producing efficiency of protein yield,the optimum amount of nitrogen for wheat variety Jinan17 are 180～240kg and 180kg per hectare respectively
