Method for processing plant seed mixture

Abstract

The invention provides a method for processing a plant seed mixture, and belongs to the field of seed processing. After a seed mixture and sand are mixed, vibrated and rubbed, seeds are separated from pectin, and further filtering, separation and washing are performed to obtain seeds. On the basis of a physical mixing vibration method, chemical treatment and fermentation methods in the prior art are avoided, and the seed yield and the seed quality are improved.

Description

technical field [0001] The present invention relates to the field of seed mixture treatment, in particular, to a treatment method of plant seed mixture, more specifically, to a treatment of vegetable or fruit seed mixture, especially to a treatment method of vegetable seed mixture, more particularly A method for treating tomato vegetable seed mixtures, in particular a tomato seed and pectin mixture. Background technique [0002] At present, the processing methods of seed mixture in tomato seed production process mainly include: [0003] (1) Fermentation method, that is, place the seed mixture slurry in the container at 20-35° C. to ferment for 36-48 hours, then wash and separate to obtain seeds. However, in this treatment method, if the treatment temperature is not suitable or improper operation steps occur during the treatment, the seeds will be discolored, for example, the seeds will be browned, and this will also reduce the germination rate; [0004] (2) Acid hydrolysis...

Problems solved by technology

However, in this treatment method, if the treatment temperature is not suitable or improper operation steps occur during the treatment, the seeds will be discolored, for example, the seeds will be browned, and this will also reduce the germination rate;

[0004] (2) Acid hydrolysis method, that is to slowly pour 10ml of industrial hydrochloric acid into 14kg of seed mixture slurry, then stir to make the two fully mixed, after 15 to 30 minutes, rinse with clean water, and separate to obtain the corresponding seeds, However, studies have found that the use of hydrochloric acid in this method can damage the seeds of firm pulp varieties;

[0005] (3) Sodium carbonate extraction method is about to mix the seed mixture slurry with an equal amount of 10% sodium carbonate solution, and rinse it with clear water after placing it at room temperature for 2 days; however, the scope of application of this method is small and can only be used for small Small-scale seed production is not suitable for large-scale applications

[0006] As previously mentioned, the main disadvantage of the existing seed treatment method is: the seeds are easily browned and blackened during treatment; at the same time, the existing seed mixture treatment method may also have an impact on the germination rate of the seeds, so that the seeds Reduced germination

Equally, the use of chemical substances such as acid and alkali not only improves the cost of plant seed mixture treatment, also can make the step of aftertreatment more complicated, also can bring environmental pollution simultaneously, thus shows, in the prior art to the seed mixture The treatment method cannot achieve efficient separation of seeds, nor can it obtain high-quality seeds, and it cannot realize the green environmental protection of the separation process.
