复混肥和硅肥在水稻上已得到广泛应用 ,增产增收作用明显。但这两种肥料合成的硅复肥应用较少 ,为此我们在江口等乡镇进行水稻施用硅复肥试验 ,均取得一定效果。1硅复肥的增产作用为探索硅复肥对水稻生长的影响 ,我们特研制了总有效成分含量为 2 8%的硅复肥 ,即Ｎ∶Ｐ∶Ｋ∶Ｓ Fertilizer and silicon fertilizer in rice has been widely used, the effect of increasing production and income significantly. However, these two kinds of fertilizer synthesis of silicon compound fertilizer less, for which we in the estuary and other township rice application of silicon compound fertilizer test, have achieved some results. 1 silicon compound fertilizer production To explore the impact of silicon compound fertilizer on rice growth, we developed a total effective content of 28% of the compound fertilizer, namely N: P: K: S
