Automatic releasing device for trichogramma egg cards and method for releasing trichogramma egg cards by using device

Abstract

The invention belongs to the technical field of a trichogramma egg releasing device and method, and discloses an automatic releasing device for trichogramma egg cards and a method for releasing trichogramma egg cards by using the device. The automatic releasing device is mainly characterized by comprising a base and a frame located above the base, wherein a push plate is arranged above the base, the frame comprises a front stop block, a back stop plate, an upper stop plate and a side door, a temporary card storage cavity is defined between the front stop block and the back stop plate, an oscillating bar is arranged on the frame in the middle of the temporary card storage cavity, alignment blocks are arranged at the lower end of the oscillating bar, and the distance between the lower end ofthe side door to the upper surface of the base is slightly larger than the thickness of trichogramma egg cards. The trichogramma egg cards are sequentially pushed out and released from the lower sideof the side door, the alignment blocks in the middle perform first alignment and second alignment so that the cards cannot get stuck, an unmanned aerial vehicle is used to fly over corn fields or other crops, the trichogramma egg cards are uniformly released in the fields, the labor efficiency is high, and uniform release is realized.

Description

technical field [0001] The invention belongs to the technical field of a Trichogramma egg delivery device and a delivery method, and in particular relates to a Trichogramma egg card automatic delivery device and a method for using the device to deliver Trichogramma egg cards. Background technique [0002] In order to reduce pesticide residues and soil, air and other environmental pollution caused by spraying pesticides, biological control is mainly advocated for pest control at present, which not only reduces the drug residues of agricultural products, improves the quality of agricultural products, but also avoids soil, Environmental pollution such as air. [0003] Trichogramma is an egg parasitoid, which can parasitize the eggs of Lepidoptera pests such as corn borer, armyworm, bar borer, cotton bollworm, Spodoptera litura and cutworm. These are important agricultural pests in our country. Trichogramma The parasitism of these pests can greatly reduce the larvae of these pe...

Problems solved by technology

[0004] At present, the Trichogramma eggs are put into the following two ways: one, artificially put in, the Trichogramma eggs are made into balls or cards, and the staff manually puts the Trichogramma ovum balls or cards into the field. There are the following defects: first, the labor intensity is high and the labor efficiency is low. With the increase of personnel wages, the overall cost will further increase; second, the delivery is uneven. Moreover, due to the influence of corn blocking and feeding angle during the feeding process, the feeding is uneven; third, the construction environment is poor, and the feeding personnel walk back and forth in the corn field, and the ventilation is poor, and the operators are prone to heat stroke

Its two, adopt throwing device to put in; Trichogramma ovum is made into spherical shape, puts spherical Trichogramma ovum into the field by throwing device, because spherical Trichogramma ovum card volume is small, the quantity of Trichogramma ovum is small, making High cost, poor air permeability, and poor living environment for Trichogramma eggs reduce the survival rate of Trichogramma eggs
