Wheat seed treatment method for improving seed germination rate

Abstract

A wheat seed treatment method for improving the germination rate of seeds comprises the steps that wheat seeds are screened through a classificator, broken grains, shriveled grains, grass seeds and impurities in the wheat seeds are removed, and insect grains, diseased grains and mildewed grains in the wheat seeds are removed through manual screening; the selected wheat seeds are evenly spread on a reed mat or waterproof cloth at the thickness of 5-7 cm 10-15 days before sowing and aired for 2-3 days under the sun illumination, and the wheat seeds are turned over once every one hour in the seed airing process; wheat seeds are put into hot water at the temperature of 50-55 DEG C and stirred immediately, the water temperature is rapidly reduced to 45 DEG C, the wheat seeds are soaked at the temperature for 3 hours and then fished out, and the wheat seeds are aired after being cooled; wheat seeds soaked at a constant temperature are mixed with a pesticide, sowing is immediately carried out after seed dressing is completed, germs and pests in the seeds can be killed by drying the seeds in the sun, the seeds are dehydrated and shrunk, the permeability of seed coats is enhanced, the germination rate and germination potential of the seeds are improved, after-ripening of the seeds is promoted, and the germination rate of the wheat seeds after sowing is greatly improved.

Description

technical field [0001] The invention relates to the technical field of wheat planting, in particular to a wheat seed treatment method for improving seed germination rate. Background technique [0002] Wheat, as one of the most important food crops in the world, provides basic protein and carbohydrates for human beings. After wheat seeds are sown, they are often affected by factors such as uneven seed quality, diseases and insect pests, and seed dormancy, which make wheat seeds difficult to germinate. , The germination rate is too low, which affects the survival of wheat seedlings. There are often problems such as lack of seedlings, broken ridges, and uneven growth of seedlings. Therefore, how to solve the problem of uneven seed quality, diseases and insect pests, seed dormancy, etc. after sowing wheat seeds. Due to the influence of factors, the germination of wheat seeds is difficult and the germination rate is too low, which affects the survival of wheat seedlings. There ar...

Problems solved by technology

[0004] The present invention aims to overcome the deficiencies of the prior art, and provides a wheat seed treatment method for improving the germination rate of seeds, which can prevent broken grains, insect grains, disease grains, mold grains, etc. in the seeds from being unable to germinate normally by selecting seeds The wheat grains affect the germination rate of the seeds, and can kill the germs and pests in the seeds by drying the seeds, make the seeds lose water and shrink, enhance the permeability of the seed coat, improve the germination rate and germination potential of the seeds, and promote post-ripening. Constant-temperature seed soaking and chemical seed dressing prevent and control wheat from being infested by diseases and insect pests after sowing. The operation is simple, effective and implementable. It can greatly increase the germination rate of wheat seeds after sowing, and effectively solve the problems of uneven seed quality, plant diseases and insect pests, seed dormancy, etc. Due to the influence of factors, it is difficult for wheat seeds to germinate and the germination rate is too low, which affects the survival of wheat seedlings, and problems such as lack of seedlings, broken ridges, and uneven growth of seedlings often occur
