近年来,对施用含枸溶性硅酸盐一类肥料,引起了很大兴趣,日本、朝鲜、斯里兰卡、津巴布韦等研究工作者,通过一系列试验表明,在某些土壤上施用硅钙肥对甘蔗、水稻,玉米、谷子等作物都有显著增产效果。日本、朝鲜对硅钙肥在水稻生产中作用非常重视,已将硅钙肥施用作为水稻增产必要措施。我国从77年开始,南京江西等研究单位对硅钙肥在水稻上施用效果、生理效应、有效施用条件、硅氮、硅磷关系等进行了探讨,试验表明硅钙肥在水稻上增产效果,主要取决于土壤有效硅的含量、土壤性质和施肥水平及其环境条件。
In recent years, the use of a class of fertilizers containing citic acid soluble silicas has aroused great interest in Japan, North Korea, Sri Lanka, Zimbabwe and other researchers, through a series of experiments show that in some soil application of calcium silicate fertilizer on sugarcane , Rice, corn, millet and other crops have a significant increase in yield. Japan and North Korea attach great importance to the role of calcium silicate fertilizers in rice production. The application of calcium silicate fertilizers has been taken as a necessary measure to increase rice production. Since 77, Nanjing, Jiangxi and other research institutes have discussed the application effects, physiological effects, effective application conditions, the relationship between silicon, nitrogen and silicon and phosphorus in the application of calcium and calcium fertilizers on rice. Experiments show that the yield increase of silicon and calcium fertilizers on rice, Mainly depends on the content of soil available silicon, soil properties and fertilization levels and environmental conditions.
