摘要:
盆栽试验结果表明, 在高铁、高锰胁迫下硅对水稻生理特性、生长发育和产量有明显的正效应。 高浓度铁、锰和低浓度硅组合, 水稻根系活力和SOD酶活性最差, 丙二醛(MDA)含量最高。相反, 低浓度铁、锰和高浓度硅处理, 水稻相应的生理指标均高。高硅低铁锰组合和高硅高铁低锰组合, 较对照分别增产 15.2%和 3.4%;高铁、锰组合不施硅肥较对照减产 72.7%;低铁、锰组合不施硅肥较对照减产20.5%;高铁、高锰胁迫下施用硅肥增产 20.5%～ 72.7%, 盆栽条件下硅肥适宜用量(SiO 2 )为 0.3～ 0.6 mg·kg -1 。 田间条件下水稻硅肥的适宜用量为 450～ 900 kg·hm -2 , 平均增产10.7%, 平均增收659 元·hm -2 。
Abstract:
The result of pot experiment showed that silicon had a positive effect on the physiological characteristics, growthand development and yield of rice under the condition of high iron and manganese stress.The indexes of roots activities andthe activity of superoxide dismutase(SOD)were low, but the content of malondialdehyde(MDA)was high in the combinationof high concentration of iron and manganese.On the contrast, the indexes of above mentioned were better than that in thecombination of low concentration of ironand manganese and high concentration of silicon.The yield in the two combinationsof high silicon, low manganese, low iron and high silicon, high iron, low manganese application was increased by 15.2%and3.4%over that of control.The yield in the treatment of high iron and manganese without silicon application was decreasedby 72.7% over that of control.The yield in the treatment of low manganese, low iron and high silicon, high iron, lovo man-ganese without silicon application was decreased by 20.5%over that of control.Under high iron and manganese stress withsilicon application the yield increased by 20.5%～ 72.7%.The appropriate rate of silicon(SiO 2 )application was 0.3～ 0.6mg·kg -1 under the pot experiment condition.While, the appropriate rate of silicon(SiO 2 )application was 450～ 900 kg·hm-2 , the yield increased by 10.7%, the benefits was increased by 659 yuan·hm -2under field experiment condition.
