用盆栽的方法,分别使用7.5%戊唑·克百威、15%克·酮·福美双、15%甲柳·福美双3种不同种衣剂对郑单958玉米种子进行包衣处理,研究不同种衣剂以及不同药种配比浓度对玉米种子出苗率及苗期生长发育的影响。结果表明,克·酮·福美双对玉米种子的出苗率促进效果最好,甲柳·福美双对玉米种子出苗率的促进效果不如克·酮·福美双,但戊唑·克百威对玉米种子出苗率有明显的抑制作用。克·酮·福美双和甲柳·福美双处理的玉米种子的株高、苗粗、根条数、单株鲜质量、干质量随浓度的降低有增高趋势,对玉米的生长
The method of pot experiment was used to coat Zhengdan 958 maize seeds with three different kinds of seed coating agents, 7.5% pentoxifylline, 15% ketones, thiram and 15% Effect of Different Seed Coatings and Different Kinds of Proportion of Different Drugs on Seed Germination Rate and Growth and Development of Maize Seedling. The results showed that kefone-thiram had the best promoting effect on the germination rate of maize seeds, and the effect of promoting the germination rate of maize seeds was not as good as that of kefone-thiram. Seed germination rate was significantly inhibited. The plant height, seedling number, root number, fresh weight per plant and dry weight of corn, treated with ketones · thiram and a willow · Fumei increased with the decrease of the concentration,
