| 摘 要： | 针对水稻田亚铁过量会对水稻产生毒害作用,通过田间小区随机区组试验,研究了施入不同量FeSO4·7H2O对水稻植株性状及产量的影响.结果表明：当试验田中FeSO4·7H2O施入量大于744 kg/hm2时,水稻分蘖期株高和根系生长受到明显抑制.试验田中FeSO4·7H2O施入量的范围进一步明确,为冷浸田改良提供理论基础.

| Abstract: | The rice fields will produce ferrous excess toxicity to rice. the field randomized block experiment, the effects of dif- ferent FeSO4·7H2O fertilizer on properties and yield of rice plant. The results showed that when the experimental field of FeSO4 ·7H2O application amount is greater than 744 kg/hm2 , lower rice plant height decreased in flag leaves of grain filling stage, root growth was inhibited obviously. The range of FeSO4·7H2O fertilizer further clear in the experimental field, pro- vided the theoretical basis for the cold soak field improved. |
