以生物农药为核心基于实时测报的大棚松花菜害虫防控技术研究

Management on the Pests of Greenhouse Cauliflower with Biopesticide Based on Teal-time Monitoring

为明确以生物农药为核心基于实时测报的害虫防控技术对害虫的防控效果,本文在秋冬茬大棚松花菜上对该技术进行了试验研究。结果表明,松花菜害虫主要包括小菜蛾、菜青虫、菜螟、夜蛾类、粉虱、蚜虫、软体动物等,秋冬茬主要是银纹夜蛾、甜菜夜蛾和粉虱。以生物农药为核心基于实时测报的害虫防控技术应用后,与常规防治处理相比,虫株率下降56. 7%,虫口减退率为96. 1%,比常规防治高9.5%。试验处理和常规防治处理亩产量分别为2 680kg、2 656kg,两者无明显差异。试验结果表明,以生物农药为核心基于实时测报的害虫防控技术可以有效地防控大棚松花菜害虫的发生。

In order to evaluate the management on the pests of greenhouse cauliflower with biopesticide based on real-time monitoring,we conducted a field experiment on the greenhouse cauliflower in the autumn of 2017.The results showed that the species of pests on cauliflower mainly included Plutella xylostella,Pieris rapae,Brassica juncea,Spodoptera,Bemisia tabaci,Aphid and mollusk.The main insect pests on autumn-winter cauliflower were Spodoptera litura,Spodoptera exigua and Bemisia tabaci.After the application of this technology,the rate of plants with pest decreased by 56.7%.The amount of insect pests declined 96.1%,which was 9.5%more than the traditional management.The yields of the treatment and the traditional management were 2 680 kg and2 656 kg,respectively.The results indicate that management on the pests of greenhouse cauliflower with biopesticide based on real-time monitoring can effectively prevent and control pests on the greenhouse cauliflower.
