药剂拌种处理对大麻病虫害的防治

本文研究了利用药剂拌种方法,对大麻病虫害进行综合防治。首先通过药剂筛选试验,选出对大麻出苗率、保苗率、收获株数提高和原茎、纤维增产及防病虫效果优异的药剂组合两个;然后再进行比较试验,对这两个药剂组合防治大麻病虫害效果进行研究。研究结果表明：每公顷用10%甲霜灵（0.75kg）＋48%代森锰锌（0.9kg）＋75%克百威（1.0kg）拌种,对大麻虫害跳甲、螟虫和病害茎腐病、灰霉病的防治效果分别达71.4%、80%和75.0%、58.3%;每公顷用15%多菌灵（1.0kg）＋75%克百威（1.0kg）＋10%福美双（1.2kg）,对大麻虫害跳甲、螟虫和病害茎腐病、灰霉病的防治效果分别达57.1%、60.0%和100%、75.0%。

Seed Dressing with Chemicals to Control Diseases and Pests of Hemp

The method of controlling the diseases and pests of hemp by treating seeds with some fungicide and chemicals was studied comprehensively in this paper.Firstly,two combinations were selected,which performed better on the seedling emergence,survival seedlings rate,harvested plants,stalk and fiber yields,and cotrol efficiency.Secondly,a comparison experiment was made between the two combinations,the results showed that the combination of 10% metalaxyl,48% mancozeb and 75% carbofuran per hectare could have effects by 71.4%,80%,75.0% and 58.3% respectively on controlling flea beetle,borer,stalk rot and botrytis cinerea accordingly,and the combination of 10% metalaxyl,48% mancozeb and 75% carbofuran per hectare could have effects by 57.1%,60.0%,100% and 75.0% respectively on controlling the aboved diseases and pests.
