The Status Quo and Countermeasures of the Management and Management of Seed Market in China
2 questions In the seed market, state-owned seed companies, agricultural research institutes, agricultural colleges, and agricultural technology promotion departments rely on a good image in the hearts of farmers to give full play to their advantages and have once led the market in the seed market. However, with the involvement of a large number of collective and individual companies and the large-scale invasion of foreign companies, the competition in the seed market has become increasingly fierce, and the order of operations in the seed market has become chaotic. The counterfeit seeds seriously damaged the interests of the majority of farmers, worsened the relationship between the cadres and the masses, and affected agricultural production and social stability. 2.1 Unclear operating qualifications First, the legal person of the permit did not change with the change of legal person; The second is that the seed license is not annualized or cannot be examined, but it has expired but continues to be used; Third, some seed companies first applied for licenses to obtain bank qualification certificates in the form of joint stocks, fund-raising, and borrowing. With the changes in the market, the share capital, fund-raising and capital resources have been withdrawn. The company has become an empty shell. "; The fourth is borrowing and renting licenses for use by others, leaving little regard to the quality of seed production by others. 2.2 Unauthorized production of seeds 2.2.1 Main crop seeds First, beyond the scope of the permit for seed production licenses, unauthorized production of seeds without the approval of the local agricultural administrative department for the record; Second, there is no seed production license and illegal production of seeds; Third, small-scale seed production, and most of the seeds illegally acquired from others' bases. 2.2.2 Non-essential crop seeds One is the production of fruit seedling seedlings without the seedling production license; The second is that there is no seedling production license or the production license is followed by production of tissue culture seedlings and cutting seedlings. The third is the unlicensed production of vegetable seeds and mushroom strains. 2.3 Seed labels and bags are not standardized The first is to change the seed production date without authorization and change the previous year's Chen species to the new species of the year; The second is to change the varieties that do not sell well in the market into best-selling varieties; Third, there is no seed use instruction and statutory information on the seed label; Fourth, the transparent surface of the seed packaging bag is too small, which is inconvenient for seed buyers and seed managers to watch the seed appearance quality. 2.4 The quality of seed business operators is low The first is that seed managers have poor basic knowledge of agricultural science and poor seed use technology, and they are unable to conduct consulting services. Second, the concept of the legal system is weak, and the type of randomness is large. However, the source and quality of the seeds are asked. The seeds are randomly exchanged between the outlets and the outlets, and the seeds of the company B are sold using the company's seed sales invoice. The third is to confront the inspection of the seeds of sales of unqualified varieties or other illegal seeds, and take covert sales or open an invoice, or even invoicing, to evade inspections. The fourth is to randomly represent the seeds of a number of seed companies, failing to change their business licenses according to regulations and register with the agricultural sector. Nox sensors as one of the important members of SCR system,are composed of sensor probe and Electronic control unit.They are connected by a wire harness to measure the concentration of nitrogen oxides in tail gas and the concetration of oxygen.In practical application,the probe is installed in the tail gas pipeline of the automobile,and the concentration of the tail gas will be fed back to the electronic control unit by theceramic chip in the form of voltage.The heating temperature of the sensor probe is controlled by the electronic control unit.After a series of signal conditioning,the concentration of Nox and oxygen in the pump is finally determined.The electronic control unit communicates with the vehicle control center(ECU) through the CAN,and transmits the measured gas values to the vehicle control center(EUC )in real time,which provides the basisfor SCR injection quantity,so as to reduce the emission of NOx.
