摘要
为促进晋杂34号的大面积推广,应用单因素随机区组设计的方法,对其进行了不同灌水量对产量性状的影响及其变化规律的研究。结果表明,随着灌水量的增加,高粱的穗长、一级枝梗数、千粒质量及产量均显著或极显著地增加;拔节期100 mm以上的灌水量会与灌浆期灌水量产生产量的叠加效应。回归分析结果表明,穗长呈现对数函数曲线走向,一级枝梗数呈现logistic生长曲线走向,千粒质量、产量呈现对数函数曲线走向。
The effects and change law of yield traits with different irrigation were studied for large scale promotion of Jinza 34 by the method of single factor randomized block design. The results showed that ear length, first branches, 1 000-grain weight and yield of sorghum increased significantly or very significantly with the quantity of irrigation water increased. More than 100 mm of irrigation quantity on the jointing stage with filling stage produced additive effect. Its regression analysis showed that ear length presented a logarithmic function curve trend, the first branches presented a logistic growth curve trend, the 1 000-grain weight and yield presented a logarithmic function curve trend.
