田间试验研究轻壤质潮土氮肥基追比对冬小麦产量和品质的影响。结果表明:供试麦田氮肥施用的基追比例以4:6为宜,追肥氮在拔节期施用,可获最高小麦子粒产量。基追比不同对小麦品质也有较大影响,在基追比5～6:5～4的范围内,籽粒蛋白质含量、产量、湿面筋、沉淀值均相对较高。生育期氮素积累量对蛋白质含量与产量有显著的影响。
Effect of Dressing Ratio of Nitrogen and Topper of Nitrogen at Different Loess Plateau on the Yield and Quality of Winter Wheat in Field. The results showed that the ratio of base to chai to nitrogen application in the tested wheat field was 4: 6, and topdressing nitrogen application at the jointing stage could yield the highest yield of wheat grain. Chai than the different have a greater impact on the quality of wheat, grain-chai than in the range of 5 ~ 6: 5 ~ 4, grain protein content, yield, wet gluten, sedimentation value is relatively high. The nitrogen accumulation during the growth period had a significant effect on the protein content and yield.
