Problems solved by technology

In the above two systems, the ultrasonic direction is radiating upwards or facing up and down, which can only make the seeds roll up and down in the liquid without lateral movement, so that the plant seeds cannot get uniform ultrasonic radiation. In addition, there must be a uniform ultrasonic sound field in the container In order to ensure the normal breeding of plant seeds

Abstract

The invention relates to an ultrasound mutation breeding device. A reaction container is arranged on a base and is characterized in that a container cover which is connected in a sealing manner is arranged on the top of a reaction container body; one side wall of the reaction container body is provided with a water inlet and a water outlet arranged above the water inlet; a horizontal ultrasonic transducer set vertical to the central shaft of the reaction container body is arranged at the other side of the reaction container body; a longitudinal ultrasonic transducer set is arranged on the top of the base below the reaction container body; and a sound absorption layer is arranged along the reaction container body and the inner wall of the container cover. Parameters such as ultrasonic power and ultrasonic time of an ultrasonic wave generator are regulated, and temperature in the reaction container body is regulated in real time by applying a temperature control unit, thus exploration on parameters which influence germination of plant seeds is achieved, so that the rate of emergence of the plant seeds is improved, a germination period is shortened, and yield is increased. The ultrasound mutation breeding device disclosed by the invention is novel in structure and easy to operate.

Description

technical field [0001] The invention relates to an ultrasonic mutagenesis breeding device, in particular to a device which uses a water-cooled temperature control device and an acoustic transducer to generate ultrasonic waves to control the temperature of seeds and radiate ultrasonic waves to induce germination. Background technique [0002] The production cycle of plant seeds is long, sensitive to natural climate, and requires strict storage conditions. Therefore, the study of seed germination characteristics helps to reveal the germination characteristics of seeds, and provides guidance for the germination and production of crop seeds in agricultural production. [0003] At present, there are two main methods for studying ultrasonic breeding: [0004] 1. Use the existing ultrasonic generator or ultrasonic breaker as the ultrasonic transmitter to establish an ultrasonic breeding system. The specific method is: soak the pretreated plant seeds into a glass or container fille...
