本试验对不同类型春小麦品种的茎秆强度进行了研究,结果表明,不同类型春小麦品种间茎秆强度有明显的差异,在不同的发育时期不同类型的品种茎基部的抗折能力有明显的不同,在小麦的开花期,乳熟期,蜡熟期和成熟期,分别对小麦茎秆的强度进行测试,抗旱类型小麦品种的茎秆强度为最强。小麦茎秆的强度与产量有明显的关系,随着小麦茎秆强度的增强,其产量也随之增加,小麦的茎秆强度与产量呈显著正相关,相关系数为0.8986。小麦的茎秆强度强,表明小麦的抗倒伏能力强,适合于密植,为小麦的群体协调发育及创造高产提供有利条件,同时给春小麦超高产、优质栽培及育种提供了科学依据。
In this study, the stalk strength of different types of spring wheat varieties were studied. The results showed that the stalk strength of different types of spring wheat varieties were significantly different. At different developmental stages, the bending strength of different types of stalks was significantly different The wheat stalks were tested for their strength at flowering, milky milking, wax ripening and maturing periods, respectively. The stalk strength of the drought-resistant wheat cultivars was the strongest. Wheat stalk strength and yield have a clear relationship, with the increase of wheat stalk strength, its yield also increases, wheat stalk strength and yield was significantly positively correlated with a correlation coefficient of 0.8986. Strong stalk of wheat, indicating that wheat lodging resistance is strong, suitable for close planting, coordinated development of wheat populations and create high yield to provide favorable conditions, at the same time to spring wheat high yield, high quality cultivation and breeding provide a scientific basis.
