Efficient and optimal accelerating germination and bud refining method for wheat seeds

Abstract

The invention discloses an efficient and optimal accelerating germination and bud refining method for wheat seeds. The method comprises the following steps: 1, airing seeds; 2, pretreating the wheat seeds; 3, preparing a germination initiation solution; 4, soaking the seeds with the germination initiation solution; 5, preparing a nutrient soaking solution; 6, soaking the seeds with the nutrient soaking solution; 7, preparing a seed coating agent; 8, treating the wheat seeds with the seed coating agent; 9, performing accelerating germination; 10, disinfecting bud seeds; and 11, refining buds. According to the method disclosed by the invention, seed germination can be accelerated, and the germination rate is improved. In addition, due to repeated pretreatment of the wheat seeds and preparation of the seed soaking solution, the virus resistance, mould resistance, cold resistance, drought endurance and wintering ability of wheat can be obviously improved, so that the wheat seeds are rapidly germinated, early rooting is realized, buds are neat, healthy and strong, the usage amount of seeds can be effectively saved, the cost is reduced, a powerful guarantee is provided for large-scale plantation, and the method has high practical value and excellent application prospects.

Description

technical field [0001] The invention relates to the technical field of wheat breeding, in particular to a method for optimizing the germination and refining of wheat seeds with high efficiency. Background technique [0002] Wheat is the second largest food crop in my country and plays an important role in ensuring national food security. It is necessary to rely on science and technology to greatly increase the yield and quality per unit area in order to meet the needs of population growth and social development. Wheat is a major food crop widely planted in the world, but about 70% of wheat is distributed in arid and semi-arid areas. Drought has a wide and serious impact on wheat. It can simultaneously affect the photosynthesis, respiratory metabolism, water content of wheat. Conditions and changes in various enzymes and other physiological metabolic processes. Therefore, research on wheat drought resistance and drought-resistant wheat breeding have become one of the importa...

Problems solved by technology

However, in many years, due to the limitation of soil and climatic factors or the late harvest period of the previous crop, wheat sowing cannot be carried out in due time.

For example, in many areas without irrigation conditions, the soil moisture is often insufficient during wheat sowing, and conventional sowing cannot make the seeds fully utilize the existing moisture, and it is difficult for wheat to germinate, take root, and emerge; Postpone until the next rainfall, thus delaying the sowing and growth period of wheat, delaying the timely emergence of wheat seedlings, affecting the growth and development of wheat, and reducing the yield of wheat

[0004] In addition, all vigorous seeds that cannot germinate are called dormant seeds. If the dormant seeds are sown into the ground, the emergence rate will be low, resulting in reduced production; wheat seeds generally have a dormancy phenomenon. , the dormancy period of wheat is longer, and there are differences among varieties, and quite a lot of farmers now only know to choose good varieties and apply chemical fertilizers, but they are not clear about the concept of dormancy period. For agricultural production, dormant seeds The germination power is reduced, which will seriously affect the emergence rate in the field
