In organic matter and the nutritive element contents such as N, P and K.
The foundation for the sustainable control method of green that the present invention is endangered from source prevention and control banana flower thrips is as follows：
1, main prevention and control measure
The theory for following " environment protective plant protecting ", for 4 main periods of Banana Growth（Take out flower bud early period, take out flower bud and young fruit period,
Fruit expanding period and harvesting later stage）, selectively integrate variety adoption, host's isolation, cutting off male flower cluster bagging, clear garden shield bud, body-building cultivation
Training, physics and chemistry lure the control measures such as control, biological control and emergent medication, give full play to their interaction, and assembling is applicable in
In the banana flower thrips green prevention and control method in each growth period, a kind of green endangered from source prevention and control banana flower thrips of structure can be held
Continuous control technology pattern.
（1）Variety adoption
Before banana planting, the anti-thrips harm ability of kind should be fully considered.Such as to the ' William of Fujian hot-zone plantation
This ' 3 kinds of bananas such as banana, red any of several broadleaf plants and dwarf banana carry out field insect resistace identifications, the results showed that, the anti-banana flowers Ji of ' Williams ' banana
The ability of horse harm is most strong, and red any of several broadleaf plants is most weak.Therefore, should according to the banana flower thrips of different regions Jiao Yuan, a situation arises, selection is suitable
The banana pest-resistant cultivar planted with being fated, and cultivate healthy and strong tissue culture any of several broadleaf plants seedling.
（2）Host is isolated
Banana flower thrips is in addition to endangering banana and the various plants such as Cruciferae, Curcurbitaceae, pulse family, Solanaceae, Rutaceae
The common insect pests taken, therefore should avoid planting such flowering plant, or plantation one fixed width banana flowers Ji as possible around Jiao Yuan
The non-host plant of horse makees isolation strip, can both reduce the worm sources quantity of any of several broadleaf plants garden periphery banana flower thrips, can also play attraction and guarantor
Protect the effect of natural enemy.
（3）Cutting off male flower cluster bagging
The elongation growth of bud can not only consume nutrient, but also can attract the feeding of banana flower thrips and oviposition, aggravate banana
The occurring and damage of flower thrips.Therefore, should be in fine day or timely cutting off male flower cluster in afternoon when female is after the flowers are in blossom, and the 7-10 after cutting off male flower cluster
Blue film bagging is used in it in time, reduces worm sources, mitigates the degree that causes harm.
（4）Bud is protected in clear garden
After banana harvesting, the suitable yield inhaled bud and be remarkably improved Banana tree of lower generation is left and taken, ventilation and penetrating light is generally left and taken
Preferable and more sturdy " eight " the word bud of condition, the bud for avoiding staying water sucker, cheating side bud and fruit ear vertical position, after it is liftoff in maternal plant
Face 1.2m or so place tilts and breaks apart by chopping stalk and reject extra suction bud；After staying bud, comprehensive clear garden, cut on the spot broken maternal plant stalk and
Leaf, after spread fertilizer over the fields 35-70kg quick limes per acre or spray other soil sterilants and ploughed deeply, banana flowers in soil can be killed
The pupa of thrips and overwintering worm sources reduce worm sources radix of lower generation, and the partially acidic in energy sweetening of the soil, and the broken any of several broadleaf plants bar in garden
Any of several broadleaf plants leaf is all covered under soil, its abundant retting is allowed to rot, and increases the soil organism.
（5）Healthy culture
On the basis of performing any of several broadleaf plants garden health, rational close planting and intertillage in due course, focuses on soil and go out pupa, fertilizer and water management and immune
Lure anti-Deng work.Before any of several broadleaf plants seed is planted, soil needs to impregnate, teds, sterilizes（35-70kg quick limes are spread fertilizer over the fields per acre or spray other soil
Earth disinfectant）With the processing such as whole furrow, the pupa of banana flower thrips in soil can be killed.During plantation, in due course watering, fertilizing passes through survey
Soil formula, reasonably combined nitrogen phosphoris and potassium fertilizer ratio suitably feed micro- fertilizer, bacterial manure（Taking out flower bud and young fruit period, fruit expanding period recommendation respectively
300-500 times of bacterium solution liquid irrigating root 1-2 times for flowers and fruits is added, every minor tick 10-15 days）And plant activation protein（Before taking out flower bud
Phase recommends 3% 500-1000 times of pouring root of plant activation protein wettable powder or sprays 2-3 times, every minor tick 25-30 days）, promote
While into robust plant growth, activation plant self-defensive system, enhancing plant insect resistace, accelerates bud bract and open, and
Useless bract is divested in time.
（6）Physics and chemistry lures control
1. colour table lures control
Using banana flower thrips to the sensitivity differences of different colours, flower bud and young fruit period are being taken out, is recommending every plant of banana away from flower
Hanging 1 at the about 20cm of flower bud surface lures worm colour table to trap any of several broadleaf plants flower thrips adult, can not only monitor the generation dynamic of the worm, may be used also
It reduces its oviposition and causes harm, efficiently reduce population number, reduce the dosage of chemical pesticide.Experiments have shown that banana flower thrips pair
It is orange most sensitive in yellow；It is orange that worm colour table suspension height is lured to be advisable so that colour table bottom end is concordant with bud shoulder, hang
It is advisable using colour table long side as bottom end, it is best to the field gathering effect of banana flower thrips, it can be used for the monitoring and prevention of the worm.
2. pheromones lure control
Control is lured in conjunction with colour table, addition 1 banana flower thrips pheromones lure of installation is lured on worm colour table at every, and lures worm color
Plate collaboration traps any of several broadleaf plants flower thrips adult, and banana flower thrips field insect population is monitored and controlled, reduces egg laying amount, reduces chemoprevention pressure
Power realizes green insect prevention.
（7）Biological control
Biological control is a kind of pest controlling method safely, effectively, lasting, can greatly reduce the application of chemical pesticide, mainly
Measure is including release, Protect natural enemies and applies biological pesticide.
