复配种衣剂对豌豆生长及产量的影响

Effects of Compound Seed Coating Agents on Pea Growth and Yield

选用亮盾(杀菌种衣剂)、高巧(杀虫种衣剂,间接防治病毒病)和凯普克(植物生长调节剂)3种药剂进行复配,对甜豌3号、绿宝、宝峰6号和食荚大菜豌1号等4个菜豌豆品种进行种子包衣,根据出苗率、主要农艺性状和产量表现等,研究确定最佳药种比。结果表明,药种比为1∶0.5时,甜豌3号和绿宝出苗受抑制;药种比为1∶7.5时,出苗率、农艺性状和产量无显著变化;药种比为1∶5.0时出苗率最高,幼苗长势最好,平均产量比对照增加20.5%。因此,复配种衣剂处理豌豆种子的最佳配比是:亮盾10mL、高巧20mL和凯普克10mL混匀包衣5.0kg豌豆种子。

Three farm chemicals were chosen and compounded,i.e.Liangdun(seed coating agent for preventing root rot),Gaoqiao(insect repellent for indirectly preventing virus disease)and Kaipuke(promoting plant growth)to screen out the suitable compound seed coating for pea seeds.The seeds of four vegetable pea cultivars,Tianwan 3,Lübao,Baofeng 6 and Shijiadacaiwan 1,were coated with the compound seed coating agents.The suitable ratio of agent and seed would be selected on the basis of performance of seedling rate,important agronomic characters and yield.The results were as follows:when the ratio of agent and seed was 1:0.5,the seedling emergence rates of Tianwan 3 and Lübao were restrained;when the ratio was 1:7.5,there was no significant difference in seedling emergence rate,farm characters and yield compared with the control group;when the ratio was 1:5.0,the seedling emergence rate was the highest with the best seedling quality;the average yield was 20.5%higher than that of the control group.Therefore,the best proportion of coating pea seeds with the compound seed coating agent is the formulation of the mixture of Liangdun 10 mL,Gaoqiao 20 mL and Kaipuke 10 mL for pea seeds 5.0 kg.
