集成型化肥增效剂对水稻群体质量及产量的影响

EFFECTS OF APPLYING INTEGRATED FERTILIZER COMPANION ON POPULATION QUALITY AND GRAIN YIELD IN RICE

在盆栽试验条件下,研究集成型肥料增效剂(IFC)对水稻群体质量及产量的影响。结果表明:施用IFC能扩大高效叶面积,提高冠层叶叶绿素含量和光合强度,促进根系生长,增强花后光合物质生产量,增产增收。在该试验条件下,以每盆施用IFC2～3g效果最佳。

The effects of integrated fertilizer companion (IFC) applying on population quality and grain yield in rice (cv. Shanyou 63) were studied. Application of IFC could enlarge the higheffect leaf area, increase the leaf chlorophyl content, photosynthetic rate and promote root growth. It could increase grain yield. The optimum amount of IFC application was 2～3 g per pot in the experimental condition.
