A liquid culture method for wheat seedlings

Abstract

The invention discloses a liquid culture method of wheat seedlings and belongs to the technical field of plant seedling culture. The method comprises the steps that seed selection, clean water soaking, seed soaking sterilization, constant temperature seed soaking, accelerating germination, secondary seed selection, seed arrangement, seedling hastening, seedling picking and seedling growing. In the method, in the process from seed soaking to seedling transplanting, multiple times of seed and seedling optimizing and filtering are performed, solid substrate cultivation is changed into liquid cultivation, the problems of missing seedlings and more abnormal seedlings occurring during solid substrate cultivation can be avoided, the growing uniformity of test materials can be guaranteed during seedling transplanting, and the principle that the single variant is controlled in the experiment design can be well matched. After seedling hastening, enough constantly grown seedlings with high purity can be obtained by one time and used for follow-up test, and the difficulties that the test materials grow not uniform, the malformed seedlings are too many and the seedling growth is weak caused due to the fact that wheat seeds are sowed directly can be eliminated.

Description

technical field [0001] The invention relates to the technical field of plant seedling cultivation, in particular to a method for cultivating wheat seedlings through liquid culture. Background technique [0002] In the current wheat seedling breeding experiments, researchers generally can only strictly control the seed selection process, that is, select seeds that are completely consistent in size, color, and plumpness, hoping to cultivate wheat seedlings with uniform growth or small differences , try to ensure the uniformity and accuracy of the test material selection, and facilitate the follow-up test design and sample acquisition; however, when using traditional solid substrates for seedling cultivation, due to the characteristics that wheat seedlings are not suitable for moving in solid substrates, and taking into account the consideration of culture density, Unable to remove deformed and weak seedlings in time, resulting in lack of seedlings, more deformed seedlings and ...

Problems solved by technology

[0002] In the current wheat seedling breeding experiments, researchers generally can only strictly control the seed selection process, that is, select seeds that are completely consistent in size, color, and plumpness, hoping to cultivate wheat seedlings with uniform growth or small differences , try to ensure the uniformity and accuracy of the test material selection, and facilitate the follow-up test design and sample acquisition; however, when using traditional solid substrates for seedling cultivation, due to the characteristics that wheat seedlings are not suitable for moving in solid substrates, and taking into account the consideration of culture density, It is also impossible to remove deformed and weak seedlings in time, resulting in the lack of seedlings, more deformed seedlings, and inconsistent growth. It is difficult to solve the problem, which affects the progress of the test, and even directly leads to the failure of the test.
