丸化型水稻种衣剂对直播稻生长及产量的影响

Effects of Seed Pelleting Agent XSW-3 on Growth and yield of Direct-seeded Rice

用丸化型种衣剂包衣水稻种子,通过大田直播试验,研究了丸化型水稻种衣剂对水稻生长及产量的影响,并与进口种衣剂进行了比较.结果表明,丸化型种衣剂具有促进直播水稻萌发与生长、提高秧苗综合素质、成秧率及抗逆境能力,有效防治病虫害,增产等作用.与对照相比,包衣处理成秧率、根系活力和脯氨酸含量分别提高17.4%、23.3%和34.8%;对主要病虫害防效达79.1%～97.6%;增产11.4%.其综合效果优于对比试验所用的进口种衣剂.

Effects of seed pelleting agent XSW-3 on growth and yield of direct-seeded rice were studied by means of experiment of field direct-seeding with coated rice seed. Meanwhile its effects were compared with those of a export seed coating agent. The results show that this seed pelleting agent not only could promote seed germination and seedling growth,enhance seedling qualities and adult seedling rate,increase seedling resistance to revese environments, but also could prevent diseases and pests,and enhance yield of direct-seeded rice. The adult seedling rate ,root vigor and proline content of coating treatment increased 17.4%,23.3% and 34.8% compared with uncoated controls, respectively. The prevention rate to main diseases and pests was 79.1%~97.6%.The yield of rice increased by 11.4%. The general effects of this seed pelleting agent were better than those of the export agent used in this experiment.
