Description

technical field [0001] The invention belongs to the technical field of asparagus mutation breeding, in particular to a device and method for asparagus mutation breeding. Background technique [0002] Asparagus is a large-scale marine economic red alga, which belongs to the genus Asparagus of the class of Rhodophyta Gracilaria. The output of asparagus is the second largest in my country's economic seaweed, with an annual output of about 300,000 tons, second only to kelp. my country's asparagus The output and area of ​​vegetables are both the first in the world, and the main cultivation areas are coastal areas such as Fujian, Shandong, and Zhejiang. Asparagus is mainly used for abalone feed, raw material for extracting agar gum, etc. It is also becoming more and more popular as a marine green food. Asparagus is delicious, with high protein content and balanced nutrition. It contains a lot of essential amino acids, various minerals and vitamins. It is a high-quality nutritious ...

AI Technical Summary

Problems solved by technology

At the same time, asparagus polysaccharides and polypeptides also have anti-oxidation, blood pressure-lowering, and tumor-inhibiting effects. When mutagenizing seeds of asparagus, it needs to be mutated by ultraviolet light irradiation, but there are some problems in the current cultivation device: 1. The water surface is easy to reflect ultraviolet rays, resulting in uneven mutagenesis; 2. When cultivating spores, uneven water temperature heating affects spore germination; 3. It is not convenient to extract germinated spores
