In recent years, the use of black light lamp on fishing more and more, not only can provide animal feed, saving commercial feed for fish, reduced cost of fish, for farmers to increase efficiency; But also prevent the pest damage to crops, so fish pond to install a black light can have the effect of 'kill two birds with one stone'. To introduce the following installation and usage of black light lamp:
a black light is a kind of special light, the ultraviolet light emitted by the lamp harmless to people and fish, just small intensity, low intensity of illumination, so the light of the lamp is called 'black light'. The experiment proved that many insects ( Most of agricultural pests) In 3000 ~ 4000 angstrom wavelength ultraviolet ray is the most sensitive, has the largest phototropism, and a black light emitting wavelength at around 3600, so it is a kind of decoys insects ideal light source.
a black light to lure has a variety of insects, including grain, cotton, oil, fruit and other major pests, such as corn borer, cotton bollworm, mole, armyworm, dung beetles, red aphids, cutworms, heart etc.
if the installation of black light lamp in the aquarium, and set the collision on light facilities, insects can touch fall in the aquarium. Can supply feed to its left, already so can kill agricultural pests, again receive the double effect of fish farming, extermination.
a, equipment: a black light from the ac power, black light lamp and accessories, cover, block board, lamp and so on several parts. Black light lamp shape and structure of the same as the common fluorescent tube, just bulb fluorescent powder coating by different. Currently using the black book of pipe, which has two kinds of 20 and 40 watts. A black light fittings including rectifier, relays, and switches. Accessories specifications shall be the same with the specifications of the black light lamp. Cover is to prevent the black light lamp water equipment and accessories, should be at the top of the tube and its accessories. Gear worm plate glass and other hard transparent what are available, and its length is the same as the tube length, each lamp available in insect board 3 - 4. Fixtures are available wood, bamboo, iron tripod.
2, installation and the installation of a black light principle is safe, economic, convenient and effective. A black light can be in the centre of the pool, if the surface is bigger, can be in ( Turtle class) Where centralized, fish or often active area, respectively, set up a few, fish feed on insects. Don't distance appropriate to the height of the black light lamp, the water is too high, so as not to affect the trap effect; Also cannot too low, to avoid damaged tubes when fish predation. Also can take in a black light upon a general electric method, improve the efficiency of trap. Trap efficiency can be improved 0. 7 ~ 3. 2 times.
3, using a black light. Trap black light lamp, the effect is related to climatic conditions, no rain, no wind [ Or have the breeze) Under the condition of lure is more; When the heavy rain or strong wind induced is very few. According to the weather situation should determine whether to turn on the light. Therefore, the conditional Fang Yingquan night lights.
