Description
[technical field]
The present invention relates to luring worm type light sources technical field, specifically, be a kind of lamplight insect lure type holvi glass pipe and
Preparation method.
[background technique]
158,639,000 hectares of the crop planting gross area of China 2009,108,986,000 hectares of the Farming gross area,
88,401,000 hectares of middle cereal total cultivated area, 11,949,000 hectares of beans total cultivated area, the cotton planting gross area 4,952,000 is public
Hectare, 18,414,000 hectares of the vegetable cultivation gross area, 1,849,000 hectares of tea place area, 11,140,000 hectares of orchard area, above-mentioned plantation
Crops more or less all by the threat of insect pest, and at present due to various reasons in face of insect pest threaten when, most of agricultures
Family is all prevented and treated by the way of spraying insecticide.Chemical pesticide once efficiently controlled agricultural evil within a longer period
The harm of worm is made that tremendous contribution for agricultural year stable yields.It is rich and varied however as the continuous development of chemical industry technology
Pesticidal products greatly solves the problems, such as crop pest while, a series of serious problems also generate in succession: (1) long-time service
Pesticide has generated serious side effect, so that the biotic population of resistant gene is become the dominant population of pest, drug resistance is sharply
Rise, chemical pesticide control effect is decreased obviously even invalid.(2) sharp increase of pest resistance to insecticide level, increases making for pesticide
With dosage and frequency, ramp chemical prevention cost；(3) deteriorate agroecological environment, bring soil, water, atmosphere pollution
Etc. a series of environmental issues；(4) due to largely using pesticide, keep the pesticide in soil and in sprinkling bring agricultural product residual
Severe overweight is stayed, the health of the mankind is directly threatened, while restricting agricultural products in China and entering international market, influences National Foreign Trade Balance
Easily.Chemical prevention is the hindering factor that main means administer that insect pest has become China's agricultural sustainable development.
Pest problem how is solved in environmentally friendly manner, while realizing the green non-pollution of agricultural and sideline product? in face of crop
Insect pest, " putting prevention first and combining prevention with control " are the plant protection policies that China adheres to and implements all the time.During prevention and treatment, benefit
Carrying out pest trapping with the taxis (such as the light that becomes, the taste that becomes, taxis etc.) of insect is the Main physical measure taken at present.Wherein,
Using insect phototactic characteristics, i.e., using the difference of its respective sensitive wave length of phototaxis pest, carried out using the light source of specific wavelength
Trapping, is the important component of important a physical control measure and integrated control.Rationally reduce Pesticide use
Number administers the direction that insect pest is contemporary agriculture and forestry sustainable development using physical means such as light traps.
320~400nm of wavelength is that the invisible long wave ultraviolet light of the mankind has the stronger power of trapping to hundreds of pests, in length
In the spectral region of wave ultraviolet light and visible light, spectral region is wider, lures worm type more.A kind of bright lamplight insect lure type of this law
Holvi glass pipe has high transmittance for the ultraviolet light of the wavelength region, can effectively kill a variety of common crops pests,
And it does not cause damages to environment.
