水稻种衣剂筛选研究

Research on Screening of Rice Seed Coating Agents

药剂拌种技术具有用药量小、防治成本低、对病虫害防效高、对环境友好和一防多治的优点,为了推广水稻拌种技术,实现水稻病虫害防治及减药增效绿色控害的重要举措。本研究通过田间试验,测定了3种混合药剂拌种对水稻秧苗生长情况的影响,研究结果表明,11%氟环·咯·精甲+60%吡虫啉+0.136%赤·吲乙·芸效果最优,对水稻秧苗的分蘖、根长、株高及产量等指标都有明显的提升。

Pharmaceutical seed dressing technology has the advantages of small amount of medicine,low control cost,high control effect on diseases and pests,friendly to the environment and can achieve one prevention and multiple treatment.In order to promote rice seed dressing technology,it is an important measure to achieve green control of rice diseases and pests.In this study,the effects of three kinds of seed mixing agents on the growth of rice seedlings were measured through field experiments.The results showed that 11%fluorocyclo·Roloprid+60%imidacloprid+0.136%red·indin·Yunn had the best effect.The parameters of rice seedling division,root length,plant height and yield were improved.
