摘　　要：【目的】研究硅钙钾镁肥用量对四川平原地区水稻长势、产量生长及对养分吸收利用的影响,为四川单季稻种植上合理施用提供参考。【方法】通过稻田小区试验,研究不同硅钙钾镁肥用量对水稻长势、产量及氮、磷、钾吸收利用的影响。【结果】结果表明,在四川平原水稻生产中,常规施肥基础上,增施硅钙钾镁肥处理的株高增加0.18~3.81cm,穗粒数增加4.60~16.20粒;硅钙钾镁肥施用量在600kg/hm^(2)时可提高水稻产量3.58%。增施硅钙钾镁肥600~900kg/hm^(2)可促进水稻秸秆及稻谷对氮、磷的吸收利用。【结论】综合产量及氮、磷、钾的吸收利用结果,硅钙钾镁肥的施用量以600kg/hm^(2)在四川平原水稻生产中效果最好。【Objective】The effects of different amounts of fertilizer of silicon,calcium,potassium and magnesium on rice growth,yield and nutrient utilization in Sichuan Plain were studied,which provided a reference for the rational application of single cropping rice in Sichuan.【Method】The effects of different amounts of fertilizer of silicon,calcium,potassium and magnesium on rice growth,yield and nutrient utilization of nitrogen,phosphorus and potassium through a paddy field experimentin were studied.【Result】The results showed that in rice production in the Sichuan Plain,on the basis of conventional fertilization,the plant height increased by 0.18-3.81cm,and the number of grains per panicle increased by 4.60-16.20 grains,and the amount of fertilizer of silicon calcium potassium magnesium applied was 600kg/hm^(2) can increase rice yield by 3.58%.Increasing application of 600-900kg/hm^(2) of fertilizer of silicon,calcium,potassium and magnesium can promote the utilization of nitrogen and phosphorus by rice straw and rice.【Conclusion】The application rate of 600kg/hm^(2) of fertilizer of silicon,calcium,potassium and magnesium has the best effect in rice production in Sichuan Plain.
