硅作为水稻的中量营养元素逐渐被人们所认识。实践证明,硅素可促进水稻生长发育。硅是水稻生长必需营养元素,它能提高根系活力,特别是在生殖生长阶段较明显。施用硅肥的水稻,植株直立挺拔,叶片浓绿刚健,茎基部粗壮坚韧,枯叶减少,活秆成熟,熟期提前2—3天。每穴有效穗数增加1—2穗,空秕率减少2.0—3.5％,结实率提高15—20％,穗粒数增加2—9粒,千粒重增加1.1—8.0％。
Silicon is gradually recognizing as the medium nutrient element of rice. Practice has proved that silicon can promote rice growth and development. Silicon is an essential nutrient for rice growth, which increases root vigor, especially during reproductive growth. Silicate rice plants, plants erect tall and straight, vigorous green leaves thick stem strong sturdy base, dead leaves to reduce the live straw mature, maturity of 2-3 days in advance. The number of effective panicles per ear increased by 1-2 spikes, the rate of cuttings decreased by 2.0-3.5%, the rate of seed setting increased by 15-20%, the number of spikelets increased by 2-9, and the grain weight increased by 1.1-8.0%.
