| 摘 要： | 在石灰性土壤上，通过盆栽试验研究了ＮａＨＣＯ３对耐缺Ｚｎ敏感品种水稻生长和Ｚｎ、Ｆｅ、Ｍｎ、Ｃｕ含量的影响。ＮａＨＣＯ３显著降低Ｚｎ敏感品种地上部和根部的干重，而对耐性品种没影响。ＮａＨＣＯ３减少Ｚｎ敏感品种ＺＮ、Ｆｅ、Ｍｎ的含量，而对耐性品种影响很小，耐性品种和敏感品种的Ｃｕ含量不受ＮａＨＣＯ３的影响。以上结果表明：水稻耐缺Ｚｎ与水稻对土壤中ＮａＨＣＯ３的高忍耐力有关。

| Abstract: | Pot experiments were conducted with a calcareous soil to elucidate the effects of bicarbonate 10 and 20mm) on the uptake of Zn,Fe,Mn and Cu and growth by "Zn-efficient" and "Zn-inefficient" rice cultivers.Bicarbonate decreased shoot and root dry weight of "Zn-inefficient" cultivars but not in "Zn-efficient" cultivars. Bicarbonate significantly decreased concentration of Zn,Feand Mn, in shoots of Zn-inefficient cultivars. But not in Zn-efficient cultivars. The results indicate that Zn-efficient in rice is causally related to high tolerance of plant to elavated bicarbonate concentrations in soil solution. |
