硅肥施用量及时期对寒地水稻产量和品质性状及抗倒性的影响
Effect of Silicon Application Rate and Stage on Yield , Quality and Lodging Resistance of Rice in Cold Region
摘要
Abstract
Taking two silicon fertilizers (SF) of Korean diffusive"Silica Tabs"and Chinese soluble silicon fertil-izer were used to research on effects of silicon application rate and stage on rice yield ,quality and lodging resist-ance in cold region .The random block experiment in rice field was conducted with different application rate and stage of silicon fertilizers .The results showed that application of silicon fertilizers increased rice yield signifi-cantly ,and its optimal amount varied for different varieties .Less application rate of SF resulted in worse yield , while overuse of SF caused loss of yield and low fertilizer efficiency .Therefore ,optimal application rate of SF contributed to increasing panicle numbers ,kernels per panicle ,setting percentage ,grain weight per plant ,de-creasing amylose content and protein content as well as shortening internode length and increasing stem diame-ter .Thus ,the optimal application for rice in cold region should be carried out between the highest tilleringstage to ear differentiation ,especially six kilograms per hectare of "Silica Tabs"silicon fertilizer was optimum .关键词
