硅、硫、锌、锰肥配施对水稻品质及产量的影响

Effect of Si、 S、 Zn、 Mn fertilizers combined applicationon quality and yield in rice

通过田间和盆栽试验,探讨了水稻在常规施用氮、磷肥基础上,配施硅、硫、锌、锰肥对其品质和产量的影响,试验结果表明配施硅、硫、锌、锰肥对大米碾磨品质、外观品质有一定的改善,并有一定的增产效果。以每公顷配施Si61 1～122 2kg、S30～45kg、Zn3 4kg、Mn4 0kg用量组合效果较佳,硫锌锰、硅锌锰、硅硫锌配施好于其它组合。

the pot and field experiment to study effect of Si、 S、 Zn、 Mn fertilizers combined application on quality and yield in rice, under using normal nitrogen and phosphorus fertilizer.The results showed that combining application Si、 S、 Zn、 Mn fertilizers can improve rice whet qualities, external appearance qualities and increased yield of rice.The good combination was (Si 122.2+S 30～45+Zn 3.4+Mn 4.0) kg/hm^2. S、 Zn、 Mn,Si、 S、 Zn, Si、 S fertilizer combining use are better than other combination.
