不同拌种剂对花生生长发育及产量的影响

Effect of Different Seed Dressing Agents on Growth and Yield of Peanut

在湖南4个花生主产区,选用4种不同类型的拌种剂适乐时(化学杀菌剂)、丁硫克百威(化学杀虫剂)、甲基硫菌灵(化学杀菌剂)、哈茨木霉(生物抑菌剂)对花生进行拌种试验,测定花生生长发育、病虫害状况、经济产量等因素,以评定不同拌种剂的处理效应。结果表明:拌种处理均有一定的病虫防控、保苗、增产效果,且药剂混配拌种效果大都比单一药剂拌种的好。哈茨木霉和丁硫克百威混合拌种的增产效果最好,达27.7%。

Four different types of seed dressing agents, celest （ chemical fungicides ） , carbosulfan （ chemical pesticides） , thiophanate-methyl （ chemical fungicides） , Trichoderma harzianum （ biological anti-bacterial agent） , were selected for the experiments in four major peanut producing areas of Hunan Province. The status of peanut growth, diseases, pests and economic yield was investigated to assess the effect of differ-ent seed dressing agents on peanut.The results showed that seed dressing with every tested agent had a certain effect on controlling diseases and pests, protecting seedlings, and increasing yield.The mixture of the agents had better effects compared to single one.The mixture of Trichoderma harzianum and carbosulfan had the best yield-increasing effect, which could increase the peanut yield by 27.7%.
