水稻硅营养与硅肥应用效果研究进展

The Research Development of Silicon Nutrition and Fertilizer Application in Rice

硅是水稻生长发育所需要的有益元素,对水稻的产量和品质等方面有着重要的影响。在此,根据水稻硅营养和硅肥应用研究现状,从土壤供硅能力与补硅原因、水稻植株吸硅特性、施硅的生理效应、施硅对水稻生产的影响等方面论述了水稻硅营养和硅肥应用效果研究进展,进而表明了硅素在水稻营养中的重要作用。

Silicon is one of useful nutritional ingredients for growth of rice and has important influence on yield and quality of it. Analyzing current situation of studying silicon nutrition and fertilizer, this paper summaries the research works on capacity for supply silicon of soil and reasons to add silicon, silicon uptake properties of rice, physiological effects of silicon fertilizer, impacts of silicon on rice production, and these indicate silicon play an important role in rice nutrition.
