| 摘 要： | 硅是否作物必需的营养元素,目前尚有争论.国外一些研究工作者指出,在缺硅的土壤上施用硅肥,对甘蔗、水稻等作物都有显著的增产效果.日本、朝鲜、斯里兰卡等国的研究者通过一系列的试验证明,在某些水稻土上施用硅肥也是提高水稻产量的必要措施.

| Abstract: | This article deals with silicon supplying levels and the response of rice plant to Si-fertilizer on the major paddy soils derived from red earth in South China.1.The effect of Si-fertilizer is negatively correlated with the content of available silica in soils.It seems that the critical value of available silica in paddy soils derived from red earth on quaternary red clay in the southern China may be lower than that in Japan and gores,but higher than that of Taiwan province in China. |
