山西省芦笋主要病虫害及无公害生产关键防控措施

Main Asparagus Diseases and Pests and Key Control Methods of Pollution-free Production in Shanxi Province

芦笋素有"蔬菜之王"的美誉,其作为山西省的一项外向型产业,经济效益良好,但病虫害发生严重,并成逐年扩大趋势。针对山西省芦笋主要病虫害(芦笋茎枯病、枯萎病、根腐病)发病规律以及芦笋木蠹蛾、甜菜夜蛾、斜纹夜蛾的发生规律进行研究,总结出无公害芦笋生产的关键防控措施:主要是一方面加强田间管理、改善现有的管理栽培方法;另一方面以农业、物理、生物防治为主,化学防治为辅,尽量减少化学农药的使用量,控制芦笋病虫害的发生和为害。

Asparagus industry is an important export-oriented industry in Shanxi province with good economic benefit but with pest and disease damage expending year by year. The experiments were conducted to study the regularity of outbreak of asparagus stem blight, blight, purple root rot, cossus, caterpillar, and worm moth and their control measures for pollution-free pro- duction. The results showed that, field management should be strengthened and the cultivation methods should be improved. On the other hand, agricultural, physical and biological controls should be mainly taken supplemented by chemical methods but mini- mizing the chemical pesticides to control asparagus diseases and pests.
