Description
Technical field
The utility model belongs to pest biological prevention field, is specifically related to a kind of biological control device of producing green rice.
Background technology
Paddy rice is the main cereal crops of China, in cereal crops, accounts for 26% of total area under cultivation, accounts for 43% of total grain yield.The common insect of the paddy rice of causing harm has kind more than 30.Wherein, some pest species occurs throughout the year, as striped rice borer, paddy stem borer, pink rice borer, rice leaf roller, brown planthopper etc.; Some kind some areas occurs, as rice plant skipper, rice leaf beetles; Some kind is intermittent large generation, as armyworm; The insect for recently importing into having, as rice water weevil.In these insects, most kinds are lepidoptera pest, and they are by eating into stem and stinging food blade and cause serious economic loss.For example, striped rice borer is caused harm with larva moth stem, can cause withered sheath, the withered heart and dead ears, and rice strain effective tiller is reduced, and ripening rate reduces, and thousand kernel weight declines.
For the Infection and damage of Severe pests on paddy rice, chemical pesticide remains the Main Means of current control, and the unreasonable use of agricultural chemicals causes the agricultural chemicals drift of 70%-80% or is lost in non-target organism, soil and waters serious pollution of ecological environment.Along with the continuous lifting of living standards of the people, green consumption idea is progressively rooted in the hearts of the people, and organic rice demand is improved day by day.Therefore, these insects are implemented to green prevention and control, particularly utilizing natural enemy insect to carry out biological control is inexorable trend.
The parasitic wasp of parasitic rice-stem borer ovum and Eggs of The Rice Leaf Roller is mainly Trichogramma and intends two kinds of Australia oophagous trichogrammaes, is directly oophagous trichogrammae ovum card to be sticked on rice leaf and put honeybee method majority, also has ovum card is placed in dixie cup or in plastic bottle.Directly ovum card is sticked on rice leaf, have following shortcoming: easily come off, the honeybee that falls into the water is drowned; Exposed being exposed to the sun and rain, honeybee survival rate is low; Subject to harmful animal invasion and attack, as predations such as bird, batrachia, spiders.Ovum card is put into dixie cup and have following shortcoming: Exposure to Sunlight excess Temperature, the lethality of honeybee is high; The place that chalcid fly does not stop hatching in ovum, must go out and find host immediately; Badly also easily drop as installed; In case of rainy, dixie cup humidity.Be placed on and in plastic bottle, have following shortcoming: Exposure to Sunlight excess Temperature, because oophagous trichogrammae body is few, also easily dead a little less than vitality; Chalcid fly does not stop place equally hatching in ovum; As Rig up error also easily drops.
Summary of the invention
The purpose of this utility model is to provide a kind of oophagous trichogrammae releasing device, places oophagous trichogrammae ovum card in thick bamboo tube, can avoid exposing to the sun and rain, and cost is low, can reuse, and bird, the frog, spider are difficult to enter injury oophagous trichogrammae in thick bamboo tube.
Oophagous trichogrammae releasing device of the present utility model comprises, wherein thick bamboo tube is interior hollow, and thick bamboo tube is vertically fixed on the top of support stick or the side of support stick, is preferably fixed on the side on support stick top, and support stick is in the centre of thick bamboo tube.Thick bamboo tube and support stick can adopt conventional fixed form, as screw, rivet etc.Support stick can be selected the material such as wooden stick, bamboo bar, can be cylinder, cuboid and irregularly shaped etc.
Rice plant of tillering stage, the long 0.8-1.0m of support stick of oophagous trichogrammae releasing device, the long 1.4-1.6m of rice earing stage support stick, the long 24-26cm of thick bamboo tube, diameter 4.5-5cm.
For fear of the oophagous trichogrammae ovum card damage by dragging in releasing device or blow off, middlely to cling with double faced adhesive tape, one side is bonded in thick bamboo tube, and one side is bonded at oophagous trichogrammae card backside.Field placing height preferably exceeds paddy rice 10-20cm.
The method that adopts the utility model trichogramma releases, comprises the steps:
(1) oophagous trichogrammae ovum card is placed in the thick bamboo tube of the utility model oophagous trichogrammae releasing device;
(2) the oophagous trichogrammae releasing device that oophagous trichogrammae ovum card is housed is inserted in rice field, places density and be preferably every mu of 5-10, placement direction is to be advisable with the wind, by plum blossom point layout.
The beneficial effects of the utility model are: (1) raw material are simple, low price, and cost price 2-4 unit, reusable; (2) effect is remarkable: in a. thick bamboo tube, place oophagous trichogrammae ovum card and can avoid exposing to the sun and rain; B. because can be ventilated in thick bamboo tube, thick bamboo tube be thicker, can be by sun direct projection, and temperature-rise ratio dixie cup and plastic bottle are slow; C. chalcid fly hatches in ovum, can temporarily stop, then go out to find host; D. avoid harmful animal, bird, the frog, spider are difficult to enter injury oophagous trichogrammae in thick bamboo tube.E. the field of can not dropping easily, affects control efficiency (3) Parasitism of Trichogramma high.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is Fig. 1 left view.
Wherein label 1 is thick bamboo tube, and 2 is support stick.
Embodiment
Below in conjunction with specific embodiment, utility model is described further.
