摘要
复合苯氧羧酸类物质（CBS）作为新的生化制剂，对杂交水稻制种试验。结果表明：每667m2喷8g赤霉素配合CBS制剂50ml较单喷赤霉素15g（正常用量）增产18．7kg，增12．8％，且节约赤霉素7g；较喷8g赤霉素配合浙农大Ⅱ号100ml增产59．45kg，增60．9％；喷8g赤霉素配合浙农大臣Ⅱ100ml十洞科1号250ml十磷酸二氢钾2509增产20.7kg，增15．2％。如进一步与自己研制的助效剂4号配合还可再增10kg／667m2。
A composite benzoxycarboxylate substance saved as a new biochemical preparationhad been used in cultivation of hybride rice seed production.Aeed-increasing of application of 8g gibberellin+50ml of CBS per 667m2 was 18. 7kg higherthan that of 15g gibberellin and the cortent of gibberellin-saving was 7g,increased 59. 45kg(about 60. 9% )more than that of 8g gibberellin and 100ml Zhelong NO. Ⅱ,and increased 20.7k (about 15. 2% )more than that of 8g gibberellin, 100ml zhelongda No. Ⅱ 25oml DongkeNo. 1 and 250g potassium biphosphate. Application of CBS with assisted acceleration - -reagents NO- 4 showed the best inireasing content about 28. 7kg per 667m2.
