采用盆栽试验的方法研究硅磷肥对水稻生物学性状、产量以及植株氮硅磷含量的影响。结果表明:硅肥可促进水稻体内的N、P向籽实的转移,虽然茎杆、叶片和稻壳中N、P的含量与不施硅肥相比有所降低,但由于产量增加,吸收量依然增加。硅、磷共同施用,由于促进了养分的吸收以及养分在作物体内的分配,故显著的提高了水稻的各项生物指标,增加了产量。 Pot experiments were conducted to study the effects of Si / P fertilizers on the biological characters, yield and N, P content of rice plants. The results showed that silicon fertilizer could promote the N and P translocation to rice seedlings. Although N, P content in stems, leaves and rice husk decreased compared with no silicon fertilizers, due to the increase of yield, Still increase. Silicon, phosphorus co-application, due to promote the absorption of nutrients and nutrients in the distribution of crops, it significantly increased the biological indicators of rice, increased yield.
