| 摘 要： | 为了研究硅肥对水稻产量及抗病性的影响,特选取两种硅肥,采取叶面喷施的方法进行对比试验,结果表明:硅肥叶面喷施可使水稻增产8.9%～12.3%,使鞘腐病发病率降低1.1%～1.3%,叶瘟发病率降低0.3%～2.0%,褐变穗发病率降低0.83%～5.1%,其中隆垦速效硅效果较好,较对照增产12.3%,增效117.65元/667 m2。

| Abstract: | Two silicon fertilizers were applied by foliar spraying to study the effect of silicon on yield and disease resistance of rice.The results showed that the silicon fertilizer raised the yield by 8.9 or 12.3%,lowered leaf blast by 0.3 or 2.0%,and brown ear disease by 0.83 or 5.1%.Available silicon fertilizer Longken had the best yield and benefit increase result. |
