种衣剂是指由杀虫剂、杀菌剂、复合微肥、生长调节剂、缓释剂及成膜剂等加工制成的药肥复合型种子包衣新产品。我县自１９９５年引进试验示范以来，累计推广应用面积达５８６７ｈｍ２。结果表明，花生种子采用种衣剂包衣，有利于壮苗、全苗，促进早发，有效地防治主要病虫及鼠害，能显著地增加荚果产量。据多点试验示范结果，较对照增产荚果６４３．５ｋｇ／ｈｍ２，增产率为１５．６％；百果重增５．２ｇ，百仁重增２．６３ｇ，出苗率增７．７个百分点，对苗期蚜虫防效达９０％以上，蝼蛄、金针虫防效极显著。节省工本３４５元／ｈｍ２，增加纯收益２１００元／ｈｍ２以上，投入产出比为１∶１５。
Seed coating agent refers to the new product of compound fertilizer seed coating made of insecticide, bactericide, compound fertilizer, growth regulator, sustained-release agent and film-forming agent. Since the introduction of experimental demonstration in 1995, our county has applied a total area of 5867hm2. The results showed that the peanut seed coating with seed coating is conducive to strong seedlings, seedlings, promote early onset, effectively control the major pests and rodents, can significantly increase the pod yield. According to the results of the multi-point experiment, compared with the control yield pod 643.5kg / hm2, the yield was 15.6%; fruit weight increased 5.2g, 100 Jen weight gain 2.63g, germination rate increased 7.7 percentage points, On the seedling aphids control effect of more than 90%, 蝼 蛄, golden needle insect control effect is extremely significant. Saving 345 yuan / hm2, increase net income of 2100 yuan / hm2 above, input-output ratio of 1:15.
