A Simple Mixed Sowing Method for Rice Breeding Small Materials

Abstract

The invention discloses a simple anti-mixing sowing method of small rice breeding materials. The specific method is as follows: (1) material: select materials including degradable paper bags and small breeding materials; (2) preparation of materials: punch holes with multifunctional Pliers punch some through holes on the degradable paper bag; (3) Seed soaking: put the small breeding material into the perforated degradable paper bag, then put the degradable paper bag containing the small breeding material into water for seed soaking; (4) ) Sowing: Before transplanting to the seedling bed, put the degradable paper bags on the leveled seedling bed in order and fix them; there is no need to cover mud and manage them according to the conventional seedling raising method until the seedlings can be transplanted . The invention can frame the seeds within a certain range, avoiding intermixing of seeds due to man-made or environmental changes; and can ensure that the boundaries between varieties are clear, and seedling inspection is fast 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...

Problems solved by technology

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

[0005] (2) Due to the relatively close distance between small breeding materials (referring to rice materials with a small amount of seeding due to subjective or objective reasons, ranging from a few grains to dozens of grains, 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
