Description
Technical field
The present invention relates to insect pest of the plant Prevention Technique fields, and in particular to a kind of thrips preventing control method of tobacco in seedling stage.
Background technique
China's yield of tobacco accounts for about the 30% of Gross World Product, is the big tobacco producing country of the first in the world, even more state tax revenue
One of important sources.The pest species of tobacco are various, very harmful to tobacco leaf production, according to investigations, China's tobacco pest and disease damage
Generation in rising year by year trend.The main disease of tobacco has bacterial wilt, rust, balck shank, tomato spotted wilt etc., insect pest master
There are cigarette aphid, oriental tobacco budworm, thrips, Bemisia tabaci, prodenia litura etc..Currently, long-term largely using caused by chemical pesticide " 3R "
(Residue, Resistance, Resurgence) problem is more and more prominent, and green prevention and control is anti-by comprehensive physical prevention and control, biology
Control and using measures such as efficiently low biological agents, to achieve the purpose that control harmful organism, have green, safety, can
The features such as continuing.As people are to the pay attention to day by day of own health and living environment, to tobacco disease
Insect pest carries out extensive concern of the safe and pollution-free green prevention and control by whole world various countries.
Thrips (Thrips) is the general designation of Thysanoptera Thysanoptera insect, many pests of Thripidae Thripidae
It is a kind of important pests of crops in world wide, it is widely distributed in China.Frankliniella occidentalis Frankliniella
The pests such as occidentalis, onion thrips Thrips tabaci, growing point, blade and the floral organ of the tobacco that can not only directly cause harm,
Can also high efficiency propagate the various plants such as tomato spotted wilt (TSWV) virus.2017-2018 investigation shows thrips main harm
The seedling stage and florescence of tobacco, the single plant worm amount that is averaged of entire seedling stage be up to 0.34, and prunes since tobacco has to bind at the florescence
Farming operations, therefore, seedling stage are the main period and best period of tobacco thrips prevention and treatment.In recent years, thrips on seedling stage tobacco
The extent of injury and damaging range have the tendency that further up, the gradually attention by tobacco plant protection personnel, but control method
Still to spray based on chemical pesticide, but because its reproduction speed is fast, generation overlap is serious, therefore drug resistance generates fast, is not achieved pre-
The control efficiency of phase, and chemical pesticide control is also easy to produce environmental pollution and pesticide residue.
Summary of the invention
For above situation, the present invention provides a kind of thrips preventing control method of tobacco in seedling stage.
A kind of technical solution of the present invention: thrips preventing control method of tobacco in seedling stage, comprising:
S1 pretreatment: selecting to seedbed and its prevention and treatment of surrounding enviroment thrips；Select to seedbed construction it is leeward on the sunny side and on
At air port, and thrips prevention and treatment is carried out to seedbed ambient enviroment；
S2 seedling management: after tobacco emergence, in the seeding stage, 1 glass of Predatory Mites mixture is put in every square metre of seed plate center,
The Predatory Mites mixture is wheat bran containing carrier and the 50ml mixture for substituting prey amblyseius cucumeris oudeman, 1 thrips of monitoring in every 3 days
Population density 1 above-mentioned predation is uniformly spread fertilizer over the fields in tobacco seedlings when thrips population density is more than 1 head/plant when lower than 2 heads/plant
Mite mixture, spreading fertilizer over the fields concentration is 2000/m2；When thrips population density is more than 2 heads/plant, an absorbability is sprayed in time and is killed
Worm agent puts 1 glass of Predatory Mites mixture in every square metre of seed plate center immediately after spraying again.
Further, in step S1, the prevention and treatment of surrounding enviroment thrips includes: the removing of thrips host plant and chemical prevention；
The host plant of thrips, the host plant especially to bloom, if there is kind are not planted within the scope of 50 meters of seedbed surrounding
It plants, sows first 10 days and pulled out in tobacco；For the plant in the range of surrounding 50-100 meters of seedbed, emerge first 10 days in tobacco
A chemical prevention is carried out for thrips.
Further, in step S1, the host plant of the thrips includes beggar-ticks, capsicum, eggplant, flowers.
Further, in step S1, the chemical prevention refers to, sprays imidacloprid, Acetamiprid and effective cypermethrin class
Efficiently low chemical pesticide.
Further, in step S1, seedling shed group's surrounding close proximity to ground of all seedling growth greenhouse compositions covers wide one meter or more
Black or silver-colored black plastic film.
Further, in step S2, the Predatory Mites mixture includes 10-15g wheat bran and 1500-2500 Predatory Mites.
Further, in step S2, the Predatory Mites mixture includes 12.5g wheat bran and 2000 Predatory Mites.
Further, in step S2, the systemic insecticide is the 3000-5000 of the imidacloprid soluble concentrate of 200g/L
Times liquid.
The present invention compared with prior art the utility model has the advantages that
(1) thrips of tobacco in seedling stage is prevented and treated by the amblyseius cucumeris oudeman that screening different times discharge various concentration, and then right
The tomato spotted wilt of thrips and its propagation plays the role of source control.
(2) usage amount that tobacco leaf planting produces upper chemical pesticide is reduced, the pesticide residue in tobacco leaf is reduced, protection tobacco field is raw
State environment provides reliable technical guarantee for Sustainable Development of Tobacco Leaf.
(3) the more traditional chemical prevention and control method effect of control method of the invention is more preferable and environmentally friendly, pollutes small.
