| 摘 要： | 研究了不同施氮水平及基追比对不同类型小麦籽粒品质的影响。结果表明,强筋小麦和弱筋小麦适宜的施氮范围为150～225 kg/hm2(纯氮)。但强筋小麦和弱筋小麦在施氮水平及氮肥运筹上存在差异,强筋小麦:稳定氮肥用量,在150～225 kg/hm2纯氮范围内提高氮素用量,氮肥后移,减少底氮用量,加大追氮比例有利于提高强筋粉的综合品质,而以施纯氮225 kg/hm2,基肥∶拔节肥∶孕穗肥为4∶5∶1调控效果最好;弱筋小麦:在150～225 kg/hm2纯氮范围内适量减少氮肥用量,增加基肥比例,减少追肥比例,可明显促进弱筋粉综合品质的提高,而以施纯氮150 kg/hm2,基肥∶拔节肥∶孕穗肥为6∶3∶1调控效果最佳。

| Abstract: | The effects of nitrogen rates and dressing ratios on grain quality of strong gluten wheat Zhengmai 9023 and weak gluten wheat Yumai 50 were studied in a field experiment.The results showed that the suitable nitrogen amount for both kinds of wheats ranged fron 150 to 225 kg/ha pure nitrogen according to the soil fertility difference in high-yielding field.However,the nitrogen rates and nitrogen application strategies were different between strong gluten wheats and weak gluten wheats because of their diferent end-use properties.For strong gluten wheats,the nitrogen application strategy was to improve its general quality by increasing the amount of nitrogen within the range of 150-225 kg/ha pure nitrogen,reducing the amount of bottom nitrogen,and strengthening nitrogen proportion of dressing,so about 225 kg/ha of nitrogen was recommended with an application ratio of 4∶5∶1 for bottom,Jointing stage and booting stage. For weak gluten wheats,the nitrogen application strategy was reduce the amount of nitrogen within the range of 150-225 kg/ha pure nitrogen,increase the proportion of bottom and reduceing the proportion of dressing,and about 150 kg/ha of nitrogen was suggested with a nitrogen ratio of 6∶3∶1 for bottom,jointing stage and booting stage. |
