以强筋小麦品种洲元9369为试验材料,研究了追施缓释尿素对强筋小麦群体及产量和品质的影响。结果表明,在基施条件相同的情况下,返青期追施127.5 kg/hm~2(按纯氮计)缓释尿素处理与追施150.0kg/hm~2普通尿素处理相比,冬前群体、最大群体及株高等差异不显著;各处理冬前平均茎蘖数为2.97个,小麦个体发育良好;强筋小麦洲元9369的成穗率提高1.2个百分点,产量显著提高(9 364.5 kg/hm~2>9 127.5kg/hm~2),提高了有效穗数和千粒重,对穗粒数的影响不大;对籽粒蛋白质的含量无显著影响,增加了湿面筋含量与面团形成时间,降低了面粉沉降值、面团稳定时间和吸水率。 Taking strong gluten wheat variety Chaoyuan 9369 as experimental material, the effects of topdraft slow release urea on the population and yield and quality of strong gluten wheat were studied. The results showed that under the condition of the same basal conditions, the top-winter population of 127.5 kg / hm ~ 2 (pure nitrogen) sustained-release urea treatment and the upper 150.0 kg / , And the maximum population and plant height were not significant. The average number of stems and tillers per plant before the winter was 2.97 and the individuals of wheat were well developed. The yield of strong gluten wheat Chayuan 9369 increased by 1.2% and the yield was significantly increased (9 364.5 kg / hm ~ 2> 9 127.5kg / hm ~ 2) increased the effective panicle number and 1000-grain weight, but had little effect on the number of grains per spike. There was no significant effect on the grain protein content, increased wet gluten content and dough formation time, Flour settlement, dough stabilization time and water absorption.
