轻壤质潮土氮肥基追比对小麦产量与品质的影响

Effect of Base to dressing Ratio of Nitrogen Fertilizer on Wheat Yield and Quality in Light - loamy Chao Soil

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。

The effect of base to dressing ratio of nitrogen fertilizer on yield and quality of wheat was studied through a field trial in the light - loany Chao (Aquic cambisols) Soil. The result showed that in the given field, the suitable ratio of base to dressing for nitrogen fertilizer should be 4:6 to get the highest grain yield, and the dressing nitrogen shauld be applied at jointing stage. The base to dressing ratio of nitrogen was 5-6:5-4. The amount of nitrogen accumulation in wheat plant was also associated with the yield and quality of protein in wheat grains.
