番茄的棚室栽培,是北方地区错季生产的基本模式,但由于其连年多茬的种植特点,使得许多病虫发生危害非常严重。为搞好棚室生产,特向广大菜农介绍主要病虫害无公害防治技术如下。 1.温室白粉虱。①黄板诱杀:黄色对白粉虱成虫具有强烈的诱集作用,在棚室内设置长条形黄板(表面涂一层粘油),诱集、粘杀成虫效果显著,一般每667平米设置30～35块为宜。②释放丽蚜小蜂:在白粉虱发生较轻时,可以在棚室内按每株15～20头的量释放丽蚜小蜂,半月1次,连放3次,进行生物防治。
Tomato greenhouse cultivation is the basic pattern of stagnant season production in northern China, but due to its multi-year planting characteristics, many pests and diseases are harmed seriously. To do a good job studio production, especially to the majority of farmers introduced the main pests and diseases pollution prevention and control technologies are as follows. Greenhouse whitefly ① Yellow board trapping and killing: Yellow has a strong trapping effect on adult whitefly adults. In the shed room, a strip of yellow board (coated with a layer of viscous oil) is provided. The effect of trapping and sticking adults is remarkable. Generally, the setting of 30 per 667 square meters ~ 35 is appropriate. ② release aphids bee: when the whitefly occurs lightly, you can release 15 ~ 20 head per plant in the amount of rameweed wasps, once a month, even put 3 times for biological control.
