Background

Asparagus is a high-grade vegetable used as both medicine and food, and the global asparagus planting area has a rapid growth trend from the end of the 60 th century. In the global asparagus major country, the total yield of China is first, and China has become a world asparagus major country. Along with the continuous expansion of the planting scale of asparagus in China, higher requirements are put on the yield and quality of the asparagus. The hermaphroditic strain of asparagus directly influences indexes such as yield, resistance, quality and the like through the serious separation of sexual propagation hybrid offspring. In order to maintain the characteristics of excellent plants, tissue culture is often used for cultivating seedlings.

The sugar-free tissue culture of plants is a new technology in tissue culture, uses carbon dioxide to replace sugar as a carbon source of plants, and solves the problems of high pollution rate, poor growth and development of plants, glass seedlings, multiple malformed seedlings and the like in the traditional tissue culture. The stem sections of the asparagus are used as propagation materials to be placed in a culture medium of a tissue culture device, and root is generated in a proper environment controlled manually, and finally the seedling grows. However, in the transitional transplanting process of the asparagus seedling, the asparagus seedling partially dies due to inadaptation to natural environment, and the death rate is too high, so that the breeding cost is increased, and the tissue culture device is required to be adjusted, and the survival rate of the seedling is increased.

In summary, the asparagus tissue culture device has obvious inconvenience and defects, so that improvement is needed.
