| 摘 要： | 通过对123个不同水稻品种在纯水、5种大量元素和5种大量元素+8种微量元素3个处理条件下的发芽势、发芽率、出苗率等11项生理指标变化情况进行了试验研究,结果表明:加入8种微量元素,水稻苗期的平均株高、平均根数、平均单株总根长、单株干重、单株鲜重、单株苗干重、去苗后籽粒干重和种子贮藏物质利用率等8项生理指标都得到极显著的提高,说明8种微量元素对水稻幼苗的生长作用极其明显,而且微量元素有促进种子内部营养转化,加快幼苗生长的作用。

| Abstract: | An experiment was conducted to test the sprouting potential,sprouting rate and emergence rate of 123 rice varieties treated with pure water,five major elements and five major elements plus eight trace elements.The results showed that the treatment with eight trace elements could increase eight physiological traits significantly involving mean seedling height,mean roots,mean total root length,dry weight per seedling,fresh weight per seedling,dry seed weight after removing seedling,and utilization efficiency ... |
