摘要： 为探索自主研制的2%戊唑醇生物复合种衣剂(BCSA)提高水稻发芽率和生长量的可行性，按不同剂量对水稻种子包衣，并选用39%精甲霜灵·嘧菌酯、600g/L吡虫啉、10.6%戊唑醇·福美双、35%噻虫嗪等悬浮种衣剂分别按药种比1:250、1:250、1:60、1:500为对照，开展了室内试验。结果表明，BCSA最适包衣剂量与发芽温度有关，在20~30℃范围内，温度高，BCSA用量略低，反之，温度低，BCSA用量略高。在20℃时，BCSA和4种对照药剂包衣种子比裸种对照发芽率分别提高5.77%、0.38%、1.53%、-0.39%、3.84%；与4种包衣剂处理和裸种对照相比，BCSA包衣种苗根长分别增长91.85%、154.37%、186.85%、118.09%和67.19%，芽长分别增长52.43%、93.81%、103.50%、50.74%和38.44%。水稻种子播入泥浆时，BCSA的最佳药种比例为1:50，在出苗后第35天，出苗率、地上和地下部分鲜重较裸种对照分别提高7.58%、18.96%、15.07%。

Abstract: To improve the germination rate and growth of rice, home-made 2% tebuconazole biological complex seed-coating agent (BCSA) was used with different doses for coating rice seeds, 4 seed-coating agents, 39% matalaxyl-M azoxystrobin, 600 g/L imidacloprid, 10.6% tebuconazole thiram and 35% thiamethoxam were used with the ratios of the agent to seed weight, 1:250, 1:250, 1:60 and 1:500, respectively, as chemical controls. The results showed that the optimal doses for BCSA were related to germination temperature, namely the higher temperature was, the lower BCSA dose and vice versa between 20-30℃. At 20℃, the germination rate of rice seeds coated with BCSA and the 4 agents were 5.77%, 0.38%, 1.53%, -0.39% and 3.84% higher than that of the naked seed control (NSC). The root of seedlings from BSCA-coated seeds were 91.85%, 154.37%, 186.85%, 118.09% and 67.19% longer, the sprout of those were 52.43%, 93.81%, 103.50%, 50.74% and 38.44% longer than those of the four chemicals and NSC, respectively. The best ratio of BCSA to seeds was 1:50 when rice was seeded in mud. The emergency rate, fresh weights of aerial and underground parts of the seedlings were 7.58%, 18.96% and 15.07% higher than those of NSC at 35 day after seeding.
