[0002] Rice is the most important food crop in the world, feeding more than half of the world's population. Seed health is an important foundation for the sustainable development of agriculture and food security in the world. Seed germination and seedling establishment are the two most critical stages in the life history of plants. They directly determine the continuation of the plant population. High germination potential and germination rate are the basis for cultivating strong seedlings, and the treatment of seeds before sowing plays a key role in their germination potential and germination rate. However, the current treatment of rice seeds method does not play a rational role; therefore, inventing a treatment method for rice seeds is of great significance to the development of the field of rice cultivation

Abstract

The invention belongs to the technical field of paddy rice planting and particularly relates to a treatment method of paddy rice seeds. The method comprises the following specific steps: firstly, selecting paddy rice seeds with full grains, no worm stings and no mildew or rot, carrying out vapor treatment, taking out the seeds, then immersing the seeds into an acetic acid solution, continuously stirring a mixed solution by a stirrer and taking out filtrate; secondly, putting the paddy rice seeds into a drying baker for drying until the moisture content is 7 to 9 percent, taking out and immersing the paddy rice seeds into a seed soaking agent for soaking, and then introducing ultrasonic waves for carrying out ultrasonic treatment; fishing out a filter reagent, carrying out constant-temperature freezing and taking out; thirdly, carrying out vacuum treatment and microwave drying until the moisture content is 14 to 18 percent. The treatment method of the paddy rice seeds has the advantagesthat the tissue protection ability of the paddy rice seeds is favorably improved, membrane repair is promoted and the sensitivity of a cell membrane to drought stress during development is reduced; in addition, the metabolism intensity of paddy rice cells can be effectively enhanced, the growth of radical buds is promoted and the transport efficiency of materials is improved; besides, the germination rate of the seeds is improved, and the resistance of young seedlings is improved, so that high germination speed, high uniformity and good growth vigor are realized.
