硅对作物的生理作用和增产效果引起了各国农业科技界的兴趣和重视,日本对作物施硅已有30余年历史,日本、朝鲜及东南亚等国把硅肥列为水稻生产的第四大元素,即氮、磷、钾、硅。我国于80年代起在南方诸省开展了水稻施硅试验示范,同时对油菜、玉米、甘蔗、红薯、柑桔、瓜果类蔬菜也进行了施 The physiological effects of silicon on crops and the effects of increased production have aroused the interest of agricultural science and technology circles in various countries. Japan has applied silicon to crops for more than 30 years. Countries such as Japan, North Korea and Southeast Asia have listed silicon fertilizer as the fourth largest element of rice production , Namely nitrogen, phosphorus, potassium, silicon. Since the 1980s, China has carried out demonstration experiments on rice silicon fertilization in various provinces in the south of the country. At the same time, we also conducted experiments on rapeseed, corn, sugar cane, sweet potato, citrus fruits and vegetables
