三唑酮药剂拌种对小麦生长发育及产量的影响效应

Effect of the Wheat Growth Development and the Output by Seed Dressing with Triadimefon Medicament

三唑酮拌种后,随着用药量增加,出苗期推迟;拌种降低了小麦出苗率;出苗期和出苗率均以湿拌影响严重;生产上应推广干拌,加大播量,拌种用药量控制在0.5‰以内.拌种有蹲苗作用,用药量增大蹲苗期延长,湿拌重于干拌.拌种促进了根系生长和植株干物质积累.拌种对产量无明显影响,干拌增加千粒重,湿拌增加亩穗数和穗粒数,实收产量差异不明显.

After seed dressing with Triadimefon, the time of seedling emergence will be postponed with the quantity of medicament increasing; the seed dressing decrease the rate of seedling emergence; the wet seed dressing will gravely affect both the time and the rate of seedling emergence of the wheat; the dry seedling dressing should be popularized in the production, increase the number of seedling, the quantity of seed dressing medicament should be controlled within 0. 5‰. the seed dressing has the action of hardening of seedling, with the increasing of the quantity of medicament, the time of hardening of seedling will be prolonged and the wet seed dressing will has more gravely effect on it than the dry seed dressing. The seed dressing promote the growth of root and the accumulation of the solids. The seed dressing has no remarkable effect on the production, the dry seed dressing will increase thousand grain weights, the wet seed dressing will increase the number of ears a unit of area and the number of seeds an ear, the difference of practically yielding is not remarkable.
