不同播期对小麦产量与品质的影响

Effect of Sowing Date to the Yield and Quality of Wheat

以中优9507和8205两个小麦品种作为材料,分析了不同播期对小麦产量和品质的影响,并进行了产量和品质以及品质间的相关分析。结果表明,随着播期的推迟,供试两品种的千粒重和产量均呈下降趋势,而蛋白质含量和湿面筋含量均呈上升趋势。相关分析表明,千粒重和产量分别与蛋白质含量、湿面筋含量呈负相关,而品质性状如蛋白质含量、湿面筋含量、干面筋含量两两皆为正相关。说明在一定播期范围内,适期早播有助增产,迟播对小麦品质有一定改善,但使产量降低。

Wheat varieties of 9507 and 8205 as superior materials, analysis of the effect of sowing date on the yield and quality, and the correlation between the quality and yield traits were conducted. The results show that with the delay in sowing date for the trial of two varieties of grain weight and production has shown a declining trend. And wet gluten content and protein content were increased. The correlation analysis shows that 1 000 - grain weight and yield were negatively correlated with protein content and wet gluten content, and quality traits such as protein content were positively correlated wet gluten content and dry gluten content. It is concluded that within a certain period of broadcast, suitable early sowing help increase yield and later broadcast is improving wheat quality, but lower output. Therefore this method is not desirable.
