优质强筋小麦品质性状在不同土壤类型上的差异性研究

Study on Differences in Quality Traits of the High-Quality Wheat in Different Soil Types

为了研究优质强筋小麦品质性状在不同土壤类型上的差异,以10个不同基因型优质强筋小麦品种(系)在5种不同土壤类型区的11个地点进行试验。结果表明,优质强筋小麦品质性状在不同土壤类型间的差异性较大,但不同性状的差异表现不一致。蛋白质含量表现为河潮土>棕壤>潮土>砂姜黑土>褐土,湿面筋含量和沉淀值表现为河潮土>棕壤>砂姜黑土>潮土>褐土,但变异系数相对较小,分别为5.80%、5.96%、12.06%;容重、硬度、面团形成时间、断裂时间、公差指数和评价值表现为砂姜黑土最优,褐土、棕壤次之,河潮土最差,容重、硬度变异系数较小为1.27%、6.38%,粉质参数变异较大,变异系数分别为10.08%、14.62%、16.90%、13.30%。

Difference in quality traits of the high-quality wheat in different soil types were studied on the condition of 10 high-quality wheat varieties with different genotypes grown in 5 soil types ( include 11 test sites ). The results shown that high different on quality traits of the high-quality wheat in different soil types, but the CV of traits in different soil types was varied. Protein content was fluvo-aquic soil>brown soil>aquent>sandy black soil>cinnamon, wet gluten content and sedimentation value were fluvo-aquic soil>brown soil>standy black soil>aquent>cinnamon, their CV were 5.80%, 5.96% and 12.06%, respectively; while volume weight, hardness, development time, break time, mechanical tolerance index and valorimeter value indicated that standy black soil was the best, the next were cinnamon soil and brown soil, fluvo-aquic soil was the lowest, the CV of volume weight and hardness were small, 1.27% and 6.38%; the CV of farinograph parameters were large, 10.08%,14.62%, 16.90% and 13.30%, respectively.
