Device for killing insects and sterilizing on surfaces of plant seeds and method thereof

Abstract

The invention relates to a device for killing insects and sterilizing on surfaces of plant seeds and a method thereof. The device comprises a storage bin, a rectifier channel and electro-curtain accelerators, wherein at least two electro-curtain accelerators are distributed on two sides of the rectifier channel. The method comprises the following steps: S1, selecting appropriate processing energyfor the electro-curtain accelerators; S2, irradiating one side of the plant seeds in an irradiation area by virtue of the electro-curtain accelerators; S3, irradiating the other side of the plant seeds in the irradiation area by virtue of the electro-curtain accelerators; S4, storing the irradiated plant seeds. The plant seeds are treated by virtue of high-dose and non-penetrating electron beam characteristics of the electro-curtain accelerators, and the aims of killing insects and sterilizing on the seed surfaces without influencing germination energy and germination rate can be achieved. Thedefects in the traditional seed treatment such as chemical residues, low efficiency, influences on the germination energy and germination rate, difficulty in long-term storage and the like are overcome, and the device can be applied to large-scale cross-regional planting of the seeds without worrying about cross-regional propagation of plant diseases and insect pests.

Description

technical field [0001] The invention relates to a new application in the technical field of electron beam irradiation, in particular to a device and method for killing insects and sterilizing the surface of plant seeds. Background technique [0002] The current mainstream methods of killing insects and sterilizing plant seeds include dry heat method, water immersion method, fumigation method and ultraviolet irradiation method. The dry heat method is to use an oven to dry the seeds at 45°C for a certain period of time in order to kill the germs and parasites on the surface of the seeds. The energy consumption is high, the treatment efficiency is low, and some high temperature resistant bacteria are difficult to kill, and the high temperature for a long time will reduce the germination rate of seeds. The water immersion method is to use straw ash, lime water and other solutions to soak the seeds in order to kill the germs attached to the seeds and achieve the purpose of reduc...

Problems solved by technology

The fumigation method is to use chemical reagents to heat and fumigate in a specific space. The fumigation method can effectively kill a variety of pests. To kill the diseases caused by germs, it is necessary to combine fumigation step by step. Deepening, fumigation reagent residues, and the impact on seed germination rate and germination potential are decreasing, but it still cannot solve the problems of no residue, fumigation tail gas does not pollute the environment, etc.

Ultraviolet irradiation is effective in killing a variety of pathogenic microorganisms. In order to achieve the bactericidal effect, long-term irradiation is required, and the operation rate of equipment is low. Long-term irradiation is prone to thermal effects, which in turn affects the germination potential and germination rate of seeds. Insect infestation is not effective

[0003] At present, there is also a way to enhance the germination rate of seeds through electron beam irradiation, but after irradiation, it will penetrate the epidermis of plant seeds and destroy the internal structure, which will affect the germination rate of seeds; the theoretical penetration thickness of 10MeV electron accelerator is: The density of the irradiated target object is 1g / cm 3 , the effective penetration is 3.96cm
