| 摘 要： | 试验研究了锌肥不同施用量对盐碱土水稻产量性状和产量的影响。结果表明:施用锌肥对水稻前期生长作用不明显,对水稻后期的生长发育及产量性状和产量的影响显著。在本试验条件下,每盆施锌肥0.4 g处理组水稻产量最高,比对照高23.0%,比每盆0.8 g处理组水稻产量高17.2%。每盆施锌肥0.2~0.6 g各处理组水稻产量均高于对照,差异均极显著(P<0.01);每盆施锌肥0.8 g处理组水稻的有效穗数降低,穗子变小,实粒数减少,产量降低。 |

| Abstract: | The effect of Zn fertilizer on rice yield and yield characters was studied in salinized soil.The result showed that Zn fertilizer significantly affects rice growth,yield and yield characters at the late growth phase rather than at the early growth phase.Under the test conditions,the highest yield comes from treatment B(0.4 g/dish),23.0% higher than that of ck and 17.2% higher than that of treatment D(0.8 g/dish).Yield of treatments A and C(0.2 g/dish,0.6 g/dish) was also higher than ck,and the difference is extremely significant(P<0.01).In treatment D(0.8 g/dish),available ear,seed number and yield decreased. |
