摘要:

‘皖西麦0638’是六安市农业科学研究院选育的弱筋小麦新品种,为探究其适播区内高产栽培技术,为其大面积推广进行栽培技术指导,设置了8种氮肥运筹方式,24个小区进行试验。结果表明:采用施氮量为234 kg/hm2、基追比为7:3:3、基肥+返青肥+拔节肥的氮肥运筹方式时,‘皖西麦0638’的株高过高,倒伏面积达到了50.00%;而施氮量为288 kg/hm2、基追比为7:3:3:3、基肥+苗肥+返青肥+拔节肥的氮肥运筹方式会导致‘皖西麦0638’的倒伏比例高达81.67%,其籽粒品质也不符合弱筋小麦标准。采用施氮量180 kg/hm2、基追比为7:3、基肥+返青肥的氮肥运筹方式,可以避免出现大面积倒伏,收获较高的产量,同时可以保证‘皖西麦0638’籽粒较好的弱筋品质。

Abstract:

‘Wanximai 0638’ is a new weak gluten wheat variety bred by Lu’an Academy of Agricultural Sciences. To explore the high-yield cultivation techniques in the suitable sowing area and guide the cultivation of the variety for large-scale promotion, the authors set up 8 kinds of nitrogen fertilizer management methods and carried out experiments in 24 plots. The results showed that under the nitrogen application rate of 234 kg/hm2, and basal/topdressing ratio of 7:3:3 for base fertilizer + striking root fertilizer + jointing fertilizer, the plant height of ‘Wanximai 0638’ was too high and the lodging area reached 50.00%. Under the nitrogen application rate of 288 kg/hm2, and the basal/topdressing ratio of 7:3:3:3 for base fertilizer + seedling fertilizer + striking root fertilizer + jointing fertilizer, the lodging rate of ‘Wanximai 0638’ was 81.67%, and the grain quality of ‘Wanximai 0638’ could not meet the standard of weak gluten wheat. Using the nitrogen application rate of 180 kg/hm2, and basal/topdressing ratio of 7:3 for basal fertilizer + striking root fertilizer, the large area lodging could be avoided, higher yield could be obtained, and the quality of weak gluten in ‘Wanximai 0638’ grains could be guaranteed.
