水稻施用硅肥试验表明，氮磷硅肥配合施用比单施氮肥生育期提前3d,分蘖率提高86．5％，增产19．4％；比氮磷肥配合施用生育期提前4d，分蘖率提高115．5％，增产10．6％；比氮硅肥配合施用生育期提前1d，分蘖率提高70．5％，增产6．0％。
The experiment of applying silicon fertilizer to rice showed that the ratio of tillering increased by 86.5% and the yield increased by 19.4% compared with that of the single application of nitrogen and phosphorus fertilizers three days earlier than the single application of nitrogen fertilizers. The growth rate of tillers increased by 115% .5% and 10.6% respectively. Compared with nitrogen and silicon fertilizer, the tillering rate increased by 70.5% and the yield increased by 6.0% when the growth period was 1 day ahead of schedule.
