【摘要】 试验以东农415水稻品种为材料,在苗期间进行11种元素缺素处理,结果如下:1、形态变化:地上部分从叶片总数、分蘖数和株高缺素处理的均低于完全培养(CK);地下部分总根数、根长、单根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、光合速率及干物质量全部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 rice varieties - DongNong415 during shooting period. The results as follows:1, form change the above ground (total leaves number, tillering number and plant high)and the under ground (branch root number, total roots number , root long)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
