Seed certification and seed quality inspection are two key links in quality control

First, what is seed certification

Seed certification is based on the seed certification program, certified by the certification body and certified by the issuance of certification certificates and certification marks to verify that a certain seed lot meets the corresponding regulatory requirements. The seeds produced through the above activities are called certified seeds. A series of activities to confirm the seed quality in three aspects: First, confirm the seed genetic quality (authenticity and breed purity) through a series of process control such as variety, seed field, seed source, field test, clean and not miscellaneous management, and verification. ) Maintaining the status and level of the original breeding of the breeder. Second, monitoring the seed sampling, marking and sealing behavior in accordance with the requirements of the certification scheme. Third, confirming the physical quality of the seed (Clarity) through inspection by the seed quality inspection agency. , Germination rate, etc.) Meet national standards or contract requirements.

The general procedures for certification include: certification must be approved by the national or provincial certification; certification of certified seed production enterprises must report the production area and base; the certification unit must conduct inspection of all seed fields during production; certification supervision agencies should be certified seed production Field inspection is conducted during the critical period of the process, and a field inspection report is issued. The certification testing agency conducts batch, sampling, and inspection of all certified seeds that are listed on the market for inspections of purity, cleanliness, and moisture indexes, and a test report is issued. The certification body issues certified seeds based on the results reported by the monitoring agency. label.

Second, what is the quality inspection of seeds?

Seed quality testing is the process of quality identification of seeds using sensory and instrumental methods. It is the key to ensure seed quality (seed quality). Grass seed testing includes the authenticity of seeds, purity, germination rate, clarity, other plants. Seed number, viability, 1000-grain weight, seed moisture, seed variety identification and seed health test, etc. The grass seed test is divided into two parts: field test and indoor test. Field test is sampling and analysis in the fields of the farmland, mainly including test seeds. Factuality and species purity, pest infestation rate, mixed degree of weeds and different crops, and fertility, with species purity as the main inspection item. Indoor inspection is after the seed is harvested and threshed, and the samples are taken at the site or warehouse until the sales sowing. The test includes the germination rate, the degree of clarity of the seeds, the number of seeds of other plants, the viability, the grain weight, the seed moisture, etc. The main steps of the seed inspection can be divided into sampling, inspection, and inspection reports. Over the years, the grass seed quality control in China The focus was on the inspection of seed quality, and the establishment and publication of the national standard “Forage Seed Inspection Regulations” was established and established. The ministerial and provincial grass seed testing and testing centers carry out special operations to provide reliable guarantees for grass seed quality control.

Third, seed certification and seed quality inspection are important methods for seed quality control

The experience of foreign forage seed quality control shows that seed certification and seed quality inspection are important methods for seed quality control. Seed certification mainly controls the seed quality from the whole process of seed production, focusing on the control of the authenticity of the seed; It is an important measure of quality control in process control, focusing on the inspection of germination rate, cleanliness and viability, and other quality traits. Seed testing can only solve problems such as the degree of clarity, moisture, germination rate, and the actual seed in the seed quality accident. The purity problem has the greatest impact. Purity testing requires a growing season, often without the identification results on the day. Once problems are found, the period is too late. If seed quality certification methods are followed, strict control of seeds during the prenatal, mid-production, and post-natal processes is adopted. Purity in order to achieve the purpose of ensuring the quality of seeds, so that we can solve the passive situation of our country's seed inspection. In addition, the work of seed quality certification is conducive to international seed trade activities. China's pasture seeds must go abroad, must and internationally specified seed production methods In order to be recognized by the world.

At present, China has issued industry standards for the implementation of the "Forage and Turfgrass Seed Certification Regulations." However, grass seed certification has not yet been fully implemented. It is far from being in line with international standards, seriously affecting the foreign trade of China's grass seeds and restricting the grass seed industry. development of.

The implementation and promotion of seed certification is the only way for the industrialization, modernization and internationalization of our country's forage seed industry. In the face of the current situation of pasturage seed industrialization, in addition to strengthening seed quality inspection, it is also necessary to carry out seed certification work to promote the sustainability of the grass seed industry. development of.
