硅肥是一种新型肥料,被国际土壤界列为继氮、磷、钾之后的第四大元素肥料。“杂交水稻之父”———中国工程院院士袁隆平对硅肥在杂交水稻中的增产作用给予了充分肯定。有专家指出,只有“氮磷钾+硅”平衡施肥,才能达到优质高产。我国硅肥的使用情况我国上世纪70年代中期开始研究硅肥,80年代后期才实现工业化生产。近几年来,我国在河南、山东、浙江、安徽、湖北、广西、海南、河北、四川等省区对喜硅作物和缺硅土壤施用硅肥,其增产 Silica fertilizer is a new type of fertilizer, which is listed as the fourth largest elemental fertilizer in the world after nitrogen, phosphorus and potassium. “Father of hybrid rice ” --- Yuan Longping, academician of Chinese Academy of Engineering fully affirmed the increasing effect of silicon fertilizer in hybrid rice. Some experts pointed out that only “NPK + silicon” balanced fertilization, in order to achieve high quality and high yield. China’s use of silicon fertilizer China’s mid-70s of last century began to study the silicon fertilizer, the late 1980s to achieve industrialized production. In recent years, China has applied silicon fertilizer to hi-silicon crops and silicon-deficient soils in Henan, Shandong, Zhejiang, Anhui, Hubei, Guangxi, Hainan, Hebei and Sichuan provinces,
