Problems solved by technology

[0004] The separation accuracy of the currently used seed processing machinery and equipment is not high, and the removal effect on seeds with small differences in density is not ideal, especially for hybrid rice seeds that germinate on the ear and germinate on the ear with small differences in specific gravity, and split glumes, and are infected with ear rot. Diseased corn seeds cannot be effectively removed and a method with higher separation accuracy is required

Abstract

The present invention belongs to the field of agricultural automation technology, and specifically relates to a device and method for removing deteriorated seeds with a liquid specific gravity method. A method for removing deteriorated seeds with the liquid specific gravity method comprises the following steps: preparing specific gravity liquid, selecting seeds and centrifugal dewatering. The method in the present invention removes the seeds with poor quality by using specific gravity difference of seeds with different plumpness, and improves the seed germination rate and planting percent. After soaking and sprouting, the selected seeds have no rejuvenation period and grow lustily and uniformly. Most of the pathogenic bacteria carried on the seed surface are killed and removed with the property of the solvent of containing anionic surfactant and antibacterial agent so as to mitigate seedling disease. With obvious effect of the calcium ions in the solvent for delaying seed aging, a stable biological membrane is formed by combining the phospholipid molecules on the cell membrane, the activity of the related pectinase is reduced, the seeding aging and cold damage are mitigated, and the storage time is longer.

Description

technical field [0001] The invention belongs to the technical field of agricultural automation, and in particular relates to a device and a method for removing deteriorated seeds by a liquid specific gravity method. Background technique [0002] The seeds of crops such as rice and corn are affected by high temperature, excessive rain, and pest damage during the production and circulation process, resulting in deteriorated seeds. Normal seeds will also produce deteriorated seeds due to adverse changes in temperature and humidity or long-term storage during storage. The removal effect of deteriorating seeds directly affects the commercial quality of seeds. Seeds with unqualified quality indicators cause quality disputes in seed production bases, and complaints from farmers purchasing seeds are common occurrences, causing huge economic losses to seed companies and consumers and even affecting the development of agricultural production. [0003] At present, the method of remov...
