采用田间试验方法,研究了灌水处理对不同筋型小麦籽粒灌浆特征的影响。结果表明,在各处理下不同筋型小麦籽粒灌浆过程呈“S”型变化趋势,并用Logistic方程进行模拟,不同筋型小麦灌浆特征参数受灌水处理的影响不同。灌二水比一水提高了临优145和临优2018籽粒各项灌浆参数,临优145各灌浆参数的变异系数大于临优2018。灌二水处理中,临优145越冬、拔节水平均灌浆速率最高,临优2018越冬、孕穗水平均灌浆速率最高。临优145和临优2018的粒重与最大灌浆速率出现的时间和渐增期时间分别达极显著与显著水平。因此,生产中可延长渐增期持续时间对增加粒重非常重要。
Field experiment was used to study the effect of irrigation on grain filling characteristics of different gluten wheat. The results showed that under different treatments, the grain filling process of different gluten wheat was the trend of “S ” and was simulated by Logistic equation. The different filling parameters of different gluten wheat were affected by irrigation. Irrigation with irrigation water increased the grain filling parameters of Linyou 145 and Linyou 2018, and the coefficient of variation of Lining 145 was higher than that of Linyou 2018. Irrigation water treatment, Linyou 145 overwintering, jointing the highest average filling rate, Linyou 2018 winter, booting rate of the highest filling rate. The grain weight and the maximum filling rate of Linyou 145 and Linyou 2018 reached the extremely significant and significant levels respectively. Therefore, prolonging the duration of ascent in production is very important for increasing grain weight.
