Convenient anti-mixing sowing method for small rice breeding materials

Abstract

The invention discloses a convenient anti-mixing sowing method for small rice breeding materials. The convenient anti-mixing sowing method specifically comprises the following steps: (1) materials: selecting materials including degradable paper bags and small breeding materials; (2) preparation of materials: punching multiple through holes in the degradable paper bags with multifunctional punchingforceps; (3) seed soaking: placing the small breeding materials in the punched degradable paper bags, and then, placing the degradable paper bags containing the small breeding materials in water forsoaking; and (4) sowing: transplanting the degradable paper bags in front of a rice seedling plate bed surface, placing and fixing the degradable paper bags on the flattened rice seedling bed surfacein order, and carrying out management by a conventional rice seedling raising method without mud covering until seedlings emerge and can be transplanted. By use of the method, seeds can be restrainedin a certain range, and mutual mixing among the seeds due to man-made or environmental changes is avoided; and the boundaries between varieties can be kept clear and seedling check is rapid and accurate.

Description

technical field [0001] The invention relates to the field of planting, in particular to a simple mixed-proof seeding method for small rice breeding materials. Background technique [0002] Rice is one of the most important food crops in my country, and more than 60% of the country's population uses rice as a staple food. Because of this, rice breeding has become an indispensable and important part of my country's agricultural scientific research field, and many agriculture-related universities, scientific research institutes, technology companies or individuals are engaged in such research work. In the process of rice breeding, it is necessary to plant a large number of parent and hybrid offspring materials. Since there are many materials to be planted, the amount of each material to be planted is small, often dozens of plants can be planted, and the sowing amount is slightly higher than the required planting amount. That is, even some materials have only a few grains due t...

AI Technical Summary

Problems solved by technology

[0004] (1) The amount of inserting cards (other markings) is large, cumbersome and time-consuming;

[0005] (2) Due to the relatively close distance between small breeding materials (referring to rice materials with little sowing amount due to subjective or objective reasons, ranging from a few to dozens of seeds, mainly breeding parents and hybrid offspring materials of each generation), When the trowel is moved back and forth, it is easy to shift the seeds, resulting in unclear boundaries between varieties or even mixing, which will make it difficult to identify seedlings in the future;

[0006] (3) A little carelessness when covering the seeds with a trowel may cause the seeds to penetrate deeper into the mud, affecting germination or even failing to germinate;

[0007] (4) Some materials may not germinate, and the number of seeds sown and the number of seedlings may deviate, resulting in difficulty in identifying varieties; etc.

In conclusion, the existing seeding methods for small materials are not only labor-intensive, time-consuming and labor-intensive, but may also lead to mechanical mixing among small materials or misalignment of missing seedling identification, affecting the accurate identification of materials
