Microwave treatment method for improving germinating ability of crop seeds

Abstract

The invention is suitable for the technical field of plant cultivation, and provides a microwave treatment method for improving the germinating ability of crop seeds. The method comprises the following step: carrying out microwave treatment on seeds 20-90 days before planting of the seeds, wherein the microwave treatment means homogeneous exposure to the seeds by microwave with optional frequency in a range of 2-40 GHz, power flow density of microwave is controlled to be (120-300) mW / cm<2>, and the homogeneous exposure means that nonuniformity of microwave radiation is less than 5 dB / cm<2>. The seeds are treated by microwave, the microwave treatment belongs to a physical method, and does not pollute the outside, the ecological environment can be protected favorably, harmful bacteria of the seeds can be killed effectively, and the seeds are sterilized; disease resistance of the seeds can be improved, and the transportation property of tissue capillary tubes in the seeds is improved; imbibitions of the seeds is facilitated, and a metabolic process from endosperm to embryo in the seeds and a plant culture medium is promoted and accelerated; and enzyme activity and respiration rate are improved, formation and growth ability of seed germination and seedling new organs are improved, and the germinating ability of the seeds is improved.

Description

technical field [0001] The invention belongs to the technical field of plant cultivation, and in particular relates to a microwave treatment method for improving the germination ability of crop seeds. Background technique [0002] In agricultural production, in order to improve seed vigor, break dormancy, and promote germination and seedling growth, seeds are usually treated before sowing, and traditional chemical methods are often used. Chemical treatment of seeds mainly refers to the application of fungicides, insecticides, Inorganic chemical reagents, plant growth regulators, etc. to treat seeds. Although this method has played certain effects on crops in terms of sterilization, disease prevention and disease resistance, and yield increase, it also has many disadvantages. On the one hand, the environmental adaptability of seeds such as disease resistance, cold resistance, and early maturity cannot be improved by chemical treatment, and the growth of rhizobia may also be ...

AI Technical Summary

Problems solved by technology

On the one hand, the environmental adaptability of seeds such as disease resistance, cold resistance, and early maturity cannot be improved by chemical treatment, and the growth of rhizobia may also be inhibited; in addition, with the improvement of people's quality of life and environmental protection awareness, food safety and The demand for organic agriculture has gradually become a national demand. People not only need to solve the problem of having enough to eat, but also need to be able to eat safely and healthily. Traditional chemical treatment methods have brought great negative effects on agricultural production and the natural environment. , can no longer meet the technical needs of the development of modern green and environmentally friendly agriculture
