氮锌硅肥是一种适用于水稻生产的新型专用肥,含氮10%、锌(ZnSO_2·7H_2O)4%、硅(SiO_2)15%。在大连市经2年20个点16000亩地试验、示范证明,增产效果显著。 1.氮锌硅肥的作用施用氮锌硅肥后,较施等氮区(亩施纯氮5千克)平均增产34.5%,较无肥区增产90%以上。对于有效硅含量不足130ppm的土 Nitrogen, zinc and silicon fertilizer is a new type of special fertilizer suitable for rice production, containing 10% of nitrogen, 4% of zinc (ZnSO 2 · 7H 2 O) and 15% of silicon (SiO 2). After two years in Dalian City, 20 points 16000 acres of land to test demonstrations that a significant increase in yield. 1. The role of zinc-silicon-silicon fertilizer After applying nitrogen-zinc-silicon-silicon fertilizer, the average nitrogen yield increased by 34.5% compared with that of the nitrogen application area (5 kg of Mushu pure nitrogen), yielding an increase of 90% or more compared with the no-fertilizer area. For effective silicon content of less than 130ppm soil
