Seeds are special, basic and irreplaceable agricultural production materials. The quality of seeds has a great impact on agricultural production and is directly related to the healthy development of agriculture and the immediate interests of farmers. At present, it is the season in which farmers purchase hybrid rice seeds. In order to allow the majority of farmers' friends to avoid losses caused by the purchase of counterfeit seeds when purchasing rice seeds, please note the following: 1. Pay attention to the purchase of seeds from the formal channels. Hybrid rice seeds belong to special franchised special commodities and only have seed business licenses, business licenses, entrustment sales agreements, county seed station registration certificates, and there are fixed business sites to operate seeds. In order to prevent the purchase of counterfeit seeds, do not buy seeds in the hands of individual farmers, and do not follow blindly and buy new so-called high-yield varieties that have not been tested and demonstrated locally. The seeds purchased must be certified by the Provincial Crop Variety Approval Committee. Second, pay attention to the purchase of seeds must be small package seeds. At present, hybrid rice seeds sold at various points of sales in our county have adopted a composite plastic packaging bag with a seed brand, seed name and hybrid combination, a production license number, a plant quarantine certificate number, and a business license. Certificate number, business unit address, contact phone number, etc.; Seed bags are filled with basic information such as seeds in the label (seed details, cultivation points), seed disinfection drugs. The seeds of this small package have passed inspection, have good storage conditions, have high germination rates, are not easily mixed, and are easy to store. Third, pay attention to understand the characteristics of the seed (combination). Before purchasing the seed, it is necessary to carefully read the description of the variety and consult the cultivation techniques of the rice seeds to understand the reproductive characteristics of the variety, including: high yield, quality (rice quality), disease resistance, adaptability, and stress resistance. Select the hybrid seeds that are suitable for your growing conditions. Fourth, pay attention to see the seed quality Seed quality four indicators: purity, clarity, germination rate, moisture. Qualified seeds are visually pleasing to the naked eye and the embryos are enriched. When embryos are planted by hand, the embryos are moistened with green color, sounded loudly with a tooth bite, the seed section is smooth, the clarity is high, and impurities are less than 2%. Put in your hands, smell and smell. For example, if the seed is dark in color, it is white, grayish or grayish blue. After the bite is broken, the section is not neat. If the impurity is more than 3%, there is strange smell. It is best not to buy it. V. Pay attention to requests for seed sales invoices. When purchasing hybrid rice seeds, it is necessary to ask the business unit for a seed sales invoice stamped with a seal of the unit, and allow the operator to specify the details of the seeds purchased, such as the seed name, quantity, date, and amount. After the seed is used, the original bags and invoices are kept well. Once the seed is found to be problematic, it is necessary to promptly find the original species-selling unit to negotiate, or complain to the seed management station, the county consumer association and other departments, so that the relevant staff can visit the site and write a written report.
