国外,特别是日本对硅肥在水稻生产中的作用非常重视,曾作为国家重点研究课题,进行了长达近二十年的研究。大量试验表明:因地制宜地施用硅肥,不仅能进一步提高水稻单位面积产量,而且具有改造某些低产田的良好效果。日本对硅对水稻的某些生理作用也进行了探讨,总结了硅肥制造、使用规律。日本农林省大力推广了硅肥的应用,奖励以矿渣为原料的硅肥生产。这对于日本战后以来大米产量年年提高,达到自给有余起了一定作用。同时,也为大量工业矿渣的利用开辟了新的途经。
Overseas, especially Japan attaches great importance to the role of silicon fertilizer in rice production. As a key national research topic, it has conducted nearly twenty years of research. Numerous experiments show that applying silicon fertilizer according to local conditions not only can further increase yield per unit area of rice, but also has the good effect of transforming some low-yielding fields. Japan also discussed some physiological effects of silicon on rice and summarized the rules of manufacture and use of silicon fertilizer. Japan’s Ministry of Agriculture and Forestry to promote the application of silicon fertilizer to reward the use of slag as raw material silicon fertilizer production. This has played a certain role in increasing the output of rice every year since the war’s end and reaching the level of self-sufficiency. At the same time, it also opens up new avenues for the utilization of a large amount of industrial slag.
