Problems solved by technology

[0004] If sufficient numbers of pollinating insects are not attracted, flower pollination of insect-borne crops may not be as ideal
This often results in reduced target crop yields and commodity quality

[0069] Measurement of Release Rate

[0070] The release rate was measured using an analytical balance to weigh 20 identical release devices containing one release device 10 with an accuracy of 0.1 mg. The release device is in contact with the environmental conditions by hanging from steel clips fixed on the chain in the horizontal direction. The release device is weighed periodically until the weight no longer changes.

[0071] A release device containing a thin tubular releaser 10 made of a mixed polymer material with a weight ratio of high-density polyethylene and ethylene-vinyl acetate of 75:25, which is sealed in the releaser 10 to enhance the pollination ability of pollinators The active substance is phenylacetaldehyde (95% by mass), which is used to enhance the pollination ability of pollinators, and the release device is placed at ambient temperature for 110 days to observe the release rate. The release rate changes as Figure 4 shown.

example 2

[0075] The field trials performed on the bee attractant-anethole are as follows:

[0076] The anethole is dispensed by injecting into the cavity of the dispenser 10 during the extrusion molding process. The polymer used was a 50:50 mixture of high-density polyethylene and ethylene-vinyl acetate containing 2% by weight of red organic pigment and 0.5% by weight of benzophenone as a UV stabilizer. The releaser 10 is sealed using an ultrasonic welder. The average wall thickness of the releaser 10 is 1.0 mm, and the length of the releaser 10 is 200 mm. The effective filling amount of the releaser 10 is 250 mg / piece.

Abstract

The invention discloses a device and a method for releasing active substance for enhancing pollination ability of pollinating insects. The device comprises a releaser (10) filled with the active substance for enhancing pollination ability of the pollinating insects. The releaser (10) is made of polymeric materials with the permeability, the active substance for enhancing pollination ability of the pollinating insects seeps through the polymeric materials and is released to surroundings in a gaseous form, so that the pollinating insects are attracted and the pollination ability is enhanced. Since the releaser (10) is filled with the active substance for enhancing pollination ability of the pollinating insects, the pollinating insects can be effectively attracted for insect-vector corps, the pollination activity of the pollinating insects is enhanced, the fruit setting percentage is improved, fruit shape is improved, and the yield and the harvest quality are improved.

Description

technical field [0001] The invention relates to the technical field of crop implements, and more specifically relates to a device and method for releasing active substances that enhance pollination ability of pollinator insects. Background technique [0002] For insect-borne crops, yield and harvest quality are largely dependent on the number and frequency of insects that pollinate the crop, such as bees. [0003] When pollinating insects are active, they may be attracted not only to the crops that are blooming, but also to other plants that are blooming at the same time as the crops. For example, wild plants with no economic value such as cruciferous, leguminous, and compositae can grow under stone fruit trees and bloom at the same time as the fruit trees, and compete with the fruit trees when attracting pollinating insects. When pollinating insects are lured away by wild plants with no economic value, it is difficult to have enough activity to complete the normal pollinat...
