据近年国内外关于农作物对硅素需要的研究表明,硅对于农作物来说也是一种极重要的肥料。尤其是禾本科植物,不仅植株的构成需要硅,而且在生长各阶段的生理过程中也很需要硅。如水稻,其茎、叶中含 SiO_2(二氧化硅)达13～18%。硅肥充足,植株生长茂盛,色绿叶挺似剑,利于接受更多的阳光,促进光合作用与物质积累,降低叶面水份蒸发量,促进生育、提高品质,增产幅度可达10～18%,并增加植株抗倒伏和抗病的能力,据对比试验,发病率可减少30～40%。又据浙江省农业厅1990年对全省水田有效硅含量的全面定点普查,全省有80%以上的水田缺硅,补
According to recent studies on the demand of silicon in crops in China and abroad, silicon is also an extremely important fertilizer for crops. Especially grasses, not only the composition of the plant requires silicon, but also the need for silicon in the physiological processes at all stages of growth. Such as rice, its stems, leaves containing SiO_2 (silica) up to 13 ~ 18%. Silicone adequate, lush plants, green leaves like sword, which will help to receive more sunlight, promote photosynthesis and material accumulation, reduce leaf water evaporation, promote fertility, improve quality, increase rate of up to 10 to 18% , And increase plant lodging and disease resistance, according to the comparative test, the incidence can be reduced by 30 to 40%. According to the Zhejiang Provincial Department of Agriculture in 1990 on the effective paddy field of the province’s full-scale routine census, the province has more than 80% of paddy lack of silicon, fill
