【摘要】 试验以高粱品种为材料,在苗期进行11种元素缺素处理,结果如下:1.形态变化:地上部分,从株高和单株干 物质量缺素处理的均低于完全培养(CK);地下部分、主根长、侧根长和侧根数缺素处理的均低于完全培养(CK)。2.生理指 标:叶绿素含量和光合速率缺素处理均低于完全培养(CK)。更多还原

【Abstract】 The experiment was conducted with 11 kinds of elements deficiency to Gaoliang during shooting period. The results as follows:1, form change the above ground (plant highand single plant dry material )and the under ground (major root long ,branch root long and branch roots number)which controlled by nutritional deficiency soluble were lower than those of complete nutritional soluble.2. Physiological index: Chorophtll content. photosynthetic rate and dry material which controlled by nutritional deficiency soluble were lower than those of complete nutritional soluble also.更多还原
