A-B1号新型水稻种衣剂研究初报

Preliminary Studies on A New Rice Seed coating Chemicals A B1

本文对杀虫剂 B1用作浸种型水稻种衣剂主剂的可行性作了初步的探讨。室内和田间的试验结果表明 :该剂型用于水稻种子包衣对种子的活力和秧苗的素质不仅无不良的影响 ,反而可以提高种子的活力。促进发芽 ,提高成秧率 ,并能够增强秧苗素质。综合分析得知 ,A- B1号种衣剂处理区种子的发芽势较种衣剂 1号、种衣剂 2号及空白处理的分别提高了 3.33% ,4.6 7%和 0 .33% ,成秧率较其它三个处理区的也分别增加了 4.5 0 %、1.34%和 1.6 7% ;其对水稻苗期主要虫害的综合防效为 91.84%。此外 ,该剂型处理还有一定的增产作用 ,较空白对照区平均理论增产 2 0 .5 5 %。

The feasibility of B1, a new insecticide, acting as main ingredient of seed coating chemicals was primarily studied in this paper. The result showed that A B1 seed coating chemicals had no by side effects on the seed vigor and the quality of rice seeding. On the contrary, it could enhance seed vigor, accelerate the speed of rice seed germination, elevate the rate of rice seeding and build up the quality of rice seeding. According to analyzing, the rate of rice seed germination of seed treatment with A B1 seed coating chemicals, seed coating chemicals type 1, seed coating chemicals type 2 and water(CK) were 95.00%,91.67%,90.33% and 94.67% respectively; the rate of rice seeding were 58.67%,51.47%,57.33%and 57.00% respectively. The result also demonstrated that the integrated control effect of A B1 seed coating chemicals was 91.84% on the major rice insects during the rice seeding. In addition, it had a good effect on rice yield.
