Seedling strengthening nutrient solution for bletilla tissue culture seedling, nutrient composition and seedling strengthening method

Abstract

The invention relates to the technical field of agriculture, in particular to a seedling strengthening nutrient solution for a bletilla tissue culture seedling, a nutrient composition and a seedling strengthening method. According to the nutrient solution, the growth and weight gaining of the bletilla tissue Seedling strengthening culture seedling root can be facilitated, and therefore the stress-resist ability of the bletilla tissue culture seedling can be enhanced. The survival rate of transplanting of the bletilla tissue culture seedling can be obviously improved, the production cycle is shortened, and the cost is saved. According to the seedling strengthening method for the bletilla tissue culture seedling, by adopting the nutrient solution for the bletilla tissue culture seedling, the survival rate of transplanting of the tissue culture seedling can be improved, the production cycle is shortened, the yield and the land utilization rate can be improved indirectly, and the cost is saved.

Description

technical field [0001] The invention relates to the field of agricultural technology, in particular to a nutrient solution, a nutrient composition and a method for growing bletilla striata tissue cultured seedlings. Background technique [0002] The seeds of Bletilla striata are very small, like powder without endosperm, and only a few cells constitute the immature embryo. It is extremely difficult to germinate and grow under natural conditions, and the cultivation of seedlings is relatively difficult. Traditional cultivation and reproduction mainly rely on division propagation, but the division reproduction cycle is long, the reproduction efficiency is low, and the consumption of seeds is large, it is difficult to meet the needs of mass cultivation. [0003] Soilless culture is a method of cultivating plants with other substances without soil, including hydroponics, mist (air) cultivation, matrix cultivation, etc. In the mid-19th century, W. Knop and others invented this m...

Problems solved by technology

[0004] It is difficult for Bletilla striata to rely on ramet propagation to meet the needs of mass cultivation. Tissue culture technology can quickly reproduce a large number of seedlings, which is far faster and more efficient than ramet propagation. However, experiments have proved that the survival rate of Bletilla striata test-tube seedlings obtained through tissue culture technology is very low. This problem not only occurs in Bletilla striata tissue culture seedlings, but also in other plants. The reason is that researchers generally focus on obtaining regenerated seedlings through tissue culture technology, and how to make them complete a complete life after obtaining regenerated seedlings. The history has not done too much research and attention. The present invention aims to study the technology of Bletilla striata tissue cultured seedlings for strong seedlings. The survival rate of Bletilla striata tissue cultured seedlings transplanted to the field for strong seedlings is significantly improved, and the stress resistance is obvious, thereby reducing It reduces the cost and difficulty of field management and has promotional value
