Description
Technical field
The present invention relates to pest control technical field, in particular to a kind of greenhouse organic vegetable phyllotreta striolata is prevented
Control method.
Background technique
Phyllotreta striolata category coleoptera, Chrysomelidae pest, abbreviation flea beetle, leaf vegetables of often causing harm, with wild cabbage, flower coconut palm
Based on the brassicaceous vegetables such as dish, Chinese cabbage, tender flower stalk, radish, turnip, rape, but solanaceous vegetables of also causing harm, melon, legume vegetable.Closely
Several years, with the adjustment of pattern of farming and popularizing for facility cultivation, the occurrence injury of phyllotreta striolata aggravated year by year.Yellow knee is jumped
Beetle state has adult, ovum, larva, pupa, directly contributes harm to plant with two worm states of adult and larva.Adult eats leaf, with children
Seedling stage is most heavy；Mainly cause harm bud and green bean in seed-plot.Larva only does harm to dish root, and moth food root skin bites fibrous root broken, blade is made to wilt
It is withered.Killed radish is in many blackspots, and last entire blackening is rotted；The aggrieved blade blackening of Chinese cabbage is dead, and propagates soft rot.
Phyllotreta striolata control method is usually to remove vegetable plot stubble to lose leaf, roots out weeds, and soil is shone in deep ploughing before sowing, and eliminates
Part pupa, adult sprinkling chemical pesticide such as suppression hooligan's missible oil, fenvalerate, fennel artemisin insecticide are prevented and treated, and larva uses enemy hundred
Worm or phoxim liquid irrigating root, or flea beetle larva is infected using entomopathogenic nematode.
Summary of the invention
Technical problem to be solved by the invention is to provide a kind of control method of phyllotreta striolata in greenhouse organic vegetable,
This method can solve the prevention and treatment problem of phyllotreta striolata in greenhouse organic vegetable, while avoid medical treatment phyllotreta striolata institute
The drug resistance of generation avoids destruction of the pesticide to farmland ecological environment and field biological chain, while being greatly reduced greenhouse
The control cost of phyllotreta striolata in organic vegetable production.
Technical scheme is as follows:
The control method of phyllotreta striolata is step 1 in a kind of greenhouse organic vegetable, the clear garden of greenhouse；Step 2, soil rotary tillage；
Step 3 hangs yellow plate；Step 4, high temperature close plastic shed；Step 5, it is aeration-cooling；Step 6 spreads fertilizer over the fields tea bran.
Each step method particularly includes:
Step 1: the clear garden of greenhouse
After the completion of the harvesting of greenhouse organic vegetable, by remaining crop material all in greenhouse, especially remaining root of the crop
The complete liquidations such as portion, weeds go out outside greenhouse, and while clearing up crop material, the yellow knee that can will stay on crop material is jumped
Nail belt goes out greenhouse, while can also take greenhouse out of in the phyllotreta striolata larva of crop root and worm's ovum etc. for hiding, thus greatly
The big insect density for reducing phyllotreta striolata in greenhouse.
Step 2: soil rotary tillage
After the clear garden for carrying out greenhouse, according to required for plantation second stubble crop, it is put into the base manure of corresponding amount, later by using dragging
Machine drawing carries out rotary tillage.The technical key point of rotary tillage is that the depth of rotary tillage must not be lower than 25 centimetres, and the diameter maximum of soil block must not be big
In 1 centimetre, full garden rotary tillage 3 times or more.The original form of soil is changed during rotary tillage, largely destroys yellow knee
The living environment of flea beetle in the soil, the water content of soil reduces especially after rotary tillage, the larva of phyllotreta striolata and worm's ovum meeting
Lead to death due to dehydration.The larva for the phyllotreta striolata that another part was originally hidden in soil layer and worm's ovum, due to rotation
Cultivated effect and be brought to upper soll layer, by being exposed to the sun for sunlight, can also be killed.It is heavy during rotary tillage simultaneously
The rotation that roll repeatedly and the rotary tillage of tractor are arrived is beaten, and the adult, larva and pieces of an egg of part phyllotreta striolata can be killed.Entire rotation
In cultivated process, there is the insect density that further reduced phyllotreta striolata in greenhouse.
Step 3: hanging yellow plate
Before crop-planting, carry out hanging for yellow plate, technical key point is as follows: the density that hangs of yellow plate is 30-50 block/mu, yellow
Plate gauge lattice (20-25) × (20-30) centimetre, hangs 20-30 centimetres of height distance ground, and the place hung is located at greenhouse surrounding,
Apart from 1-1.5 meters of greenhouse side, yellow plate is uniformly hung along four side of greenhouse.The effect for hanging yellow plate, which is that, utilizes phyllotreta striolata
To the taxis of yellow, phyllotreta striolata is traped.There is no blocking for crop in greenhouse at this time, not no phyllotreta striolata yet
Food, yellow plate is high-efficient to the trapping of phyllotreta striolata at this time.
Step 4: high temperature close plastic shed
After having hung yellow plate, whole side films of greenhouse surrounding are put down, while fastening greenhouse door, be imitated using the heat preservation of greenhouse
Fruit, by 24 hours close plastic sheds, the temperature of greenhouse inside middle can achieve 60-70 degrees Celsius, and humidity can be reduced to 30-
40%.Due to the influence of high temperature, the environment of drying, phyllotreta striolata can be hung at this time to the lower region clustering of greenhouse ambient temperature
Whole get well of yellow plate for being located at greenhouse periphery plays the role of trapping to phyllotreta striolata.Simultaneously using under the conditions of 60-70 celsius temperature
Continue 48 hours (72 hours total) again, phyllotreta striolata larva and its worm's ovum largely hidden in the soil can be killed.
Step 5: aeration-cooling
After at least 24 hours close plastic sheds, the side film of greenhouse surrounding is rolled, cooling is aerated to greenhouse, at this time due to big
The temperature on canopy periphery further decreases, and part phyllotreta striolata will continue to migrate to greenhouse periphery, and it is further to can use yellow plate
Trapping.
Step 6: spreading fertilizer over the fields tea bran
Tea bran is also tea seed cake, tea seed cake, and it is a blob of slag of the tea seed after extracting oil, effective component is saponin that particle, which is in puce,
Element can be used as a kind of vegetable source pesticide pesticide.Greenhouse after ventilation, so that it may carry out the preparation before crop is determined, at this time
The amount that 50-75kg/ mus are pressed in greenhouse, uniformly spreads fertilizer over the fields tea bran, utilizes the insecticidal action of tea bran.Crop in greenhouse has been colonized
At later, while by pouring root water, the tea bran impregnated by water can release the ingredient with insecticidal action,
Kill phyllotreta striolata adult, larva and its pieces of an egg hidden in soil.Tea bran can also be used as a kind of organic fertilizer and be simultaneously
The growth of crops provides nutrient required for growth and development.
The invention has the following beneficial effects:
1, system prevents and treats in advance
Phyllotreta striolata control method of the invention is different from common control method, that is, endangers in phyllotreta striolata
It is just prevented and treated after evil.The pest control theory of " relying mainly on prevention, prevention and treatment combines " is truly accomplished.The present invention
Hang that yellow plate → high temperature close plastic shed is → aeration-cooling → to spread fertilizer over the fields a series of prevention and control such as tea bran by the clear garden of greenhouse → soil rotary tillage →
Technical measures, it is just that the insect density of the phyllotreta striolata in greenhouse is near minimum in crops field planting to before in greenhouse, this
Also extremely beneficial condition is created for the prevention and treatment of subsequent phyllotreta striolata.
2, control efficiency is good
It is obtained according to current using effect Data Summary collected, this method is relative to usually using the anti-Yellow River harnessing knee of yellow plate
The way of flea beetle, that is, hanging for yellow plate is carried out again when crop field planting, or after field planting, effect will be got well.And
Relative to usually hanging for yellow plate is carried out again when crop is colonized, or after field planting, yellow plate of the invention uses the time
It is longer.
3, the dangerous height of wind resistance
Phyllotreta striolata control method of the invention belongs to mainly based on physical control, supplemented by botanical pesticide, the two
The technology of the organic vegetable pest control combined makes full use of the clear garden of greenhouse, soil rotary tillage, the manual operation for hanging yellow plate
