Problems solved by technology

Jian Yongxun et al. (Chinese Forest Diseases and Pests, 2001, No. 4, 5-6, 23) reported "Research on Sampling Methods for Quarantine Inspection and Inspection of Pine Wood Nematode". The method cannot get rid of the "Bellman funnel", so it still takes more than 20 hours to produce results
At various checkpoints, cargo owners and car drivers are extremely reluctant to spend more than a day at the checkpoint, which means huge economic losses
The loss caused by port quarantine due to waiting for the result is even greater...

Embodiment Construction

[0018] The present invention will be further described below in conjunction with embodiment.

[0019] Such as figure 1 As shown, the suction filter cartridge 1 is a galvanized pipe with an inner diameter of 5.5 cm, an outer diameter of 6 cm, and a height of 18 cm. The lower port of the suction filter cartridge is welded with an iron plate to seal the bottom. Drill an aperture and weld on a small section of thin pipe 11, the diameter of thin pipe is advisable to be able to be inserted into pressure-resistant pipe (plastic or hard rubber pipe). The pressure-resistant tube is connected with the vacuum pump, and the upper cylinder mouth of the suction filter cartridge is ground into a blade-like edge 12;

[0020] In order to prevent moisture from entering the vacuum pump during suction filtration, a suction filter bottle filled with silica gel can be connected between the vacuum pump and the suction filter cartridge.

[0021] Saw a section of wood about 3 to 6 cm long from pine ...

Abstract

A high-speed separator for detecting pine nematode is composed of a pumping filter barrel, a sleeve tube and a vacuum pump communicated with the tube on the wall of pumping filter barrel. Its detecting method includes such steps as embedding said pumping filter barrel and sleeve tube in pine wood to be detected, filling water in sleeve tube, pumping water in the pumping filter barrel, and detecting pine nematode by microscope. Its advantage is high speed (20-30 min).

Description

(1) Technical field [0001] The invention relates to a rapid separation device for the pathogenic nematode of pine wood nematode and a detection method thereof. (2) Background technology [0002] The pine wood nematode (Bursaphelenchus xylophilus) causes pine wilt disease, known as "smokeless forest fires" or "pine cancer". Because pine xylophilus reproduces quickly and spreads through vector insects such as longhorns, it quickly spreads and becomes a disaster, causing large areas of pine trees to die quickly. Therefore, prohibiting the movement of wood in the diseased area is one of the main measures to prevent the spread of the disease. In addition, many wooden packaging boxes for imported and exported goods are made of pine wood, which is also the main cause of the disease. In order to prevent the further spread of the disease, checkpoints have been set up on major traffic arteries across the country to intercept diseased pine trees; each port is also closely inspecting ...
