当归麻口病的致病菌为燕麦镰刀菌等真菌。致病菌通过地下害虫、线虫等多种虫害及机械创伤所形成的伤口进行复合侵染,造成麻口病.使当归质量下降、产值降低。近几年,笔者推广了”治虫防病”技术,平均防效达87％以上,特、一等归出品率提高到50％以上,收到了明显的增产增收效果。 选用健壮归苗:选长5—6cm、粗3—5mm,苗顶生长点黄亮,无侧根、无损伤的健壮归苗。可使麻口病发生率降低60％,提前抽苔率降低80％。 合理密植:亩保苗4500—5000株,可使特、一等归出成率达50％以上,亩产200公斤以上,产值千元以 Angelica gingivalis pathogenic bacteria such as Fusarium oat fungi. Pathogenic bacteria through the underground pests, nematodes and other pests and wounds formed by mechanical wounds of the composite infection, resulting in Majie disease .And the quality of Angelica decreased, the output value decreased. In recent years, I promote the “pest control disease prevention” technology, the average prevention effect of more than 87%, special, first-class return rate increased to 50% or more, received a significant effect of increasing production and income. Select robust seedlings: election length 5-6cm, thick 3-5mm, the growth point of yellow seedling Huang Liang, no lateral roots, no damage to the robust seedlings. Can reduce the incidence of sore mouth disease 60%, 80% reduction in the rate of early moss. Reasonable close planting: 4500-5000 acres of seedlings Miao, special, first class deducted into the rate of 50% or more, 200 kilograms per mu or more, the output value of thousands to
