水稻是含硅较多的植物之一,硅是水稻生长发育必需的大量元素。为了探讨水稻施硅肥增产效果,我们从1988年至1991年在黑龙江省红兴隆国营农场管理局和友谊农场十分场,进行了大田施硅增产效果的试验。试验方法试验用硅肥为当地取暖后煤灰渣,pH值8.5～10.5,全量二氧化硅 Rice is one of the more silicon-rich plants, and silicon is a large number of elements necessary for the growth and development of rice. In order to investigate the effect of silicon fertilization on paddy yield, we conducted a field test on the effect of increasing silicon production in the field from 1988 to 1991 at the Hongxinglong State Farm Management Bureau and Youyi Farm in Heilongjiang Province. Test Method Test with silicon fertilizer for the local heating of coal ash residue, pH 8.5 ~ 10.5, the total amount of silica
