以水稻品种扬粳4227为材料,研究新型水稻机插秧专用拌种剂在机插秧育秧上的应用效果。结果表明:新型机插秧专用拌种剂处理与空白对照相比,发芽率提高至96%以上,在生物量干质量、根系盘根力关键指标方面,新型机插秧专用拌种剂1号处理可达到0.82 g/10株、12.6 N,远超空白对照的0.58 g/10株、8.9 N,达显著差异。与市售普通机插秧拌种剂相比较,新型机插秧专用拌种剂优势突出,能够有效延缓超秧龄问题,增加秧龄弹性。使用新型水稻机插秧专用拌种剂拌种在育秧阶段无任何毒害或抑制作用。
The rice variety Yangjing 4227 was used as material to study the application effects of the new rice seedling planting seed dressing on seedling transplanting. The results showed that compared with the blank control, the germination rate of the new seedling-specific seed dressing increased to more than 96%. In terms of the biomass dry mass and the key indicators of root packing capacity, the new seedling-specific seed dressing treatment No. 1 Reached 0.82 g / 10 strains, 12.6 N, much higher than the blank control of 0.58 g / 10 strains, 8.9 N, a significant difference. Compared with the common seedling planting agent commercially available, the new special seedling agent for seedling planting has outstanding advantages, which can effectively delay the problem of the super seedling age and increase the elasticity of the seedling age. The use of a new rice seedling seed dressing for seed dressing in the seedling stage without any poison or inhibition.
