Core hint

White Dew grows cabbages in season. Into the seed market, colorful, colorful exquisite packaging, people are dazzled. Packaging is not necessarily a good seed. For farmers, lack of necessary means to detect seeds, how to effectively distinguish the quality and authenticity of seeds through packaging labels?

The Department of seed Science and Engineering of Tianjin Agricultural University has organized college students to collect and investigate the main seed quality and seed packaging in China's vegetable and flower seed market in their hometown with the help of winter vacation. strive to find and analyze the main problems existing in the current vegetable and flower seed market.

Through the investigation, they found that most of the seed packaging labels did not comply with the General principles of crop seed labelling, and there were deficiencies and irregularities; the seeds of some enterprises were only marked with seed category, crop type, business license and origin, and did not mark the production license, quarantine certificate number and business license number; some products did not even mark the seed category. Many treatment agents for coated seeds are toxic substances, but the name, active ingredient and content of the agents are hardly specified or marked on the bags, which may cause accidental harm to some farmers when using such seeds. In addition, the labeling content is not standard; the production date is not marked according to the prescribed format; most seed steel imprints are generally selected at the packaging seal, which is easy to cause unclear identification; some seed enterprises are labelled incomplete and non-standard, using the way of "giving full play to their strengths and avoiding weaknesses". All these may mislead farmers in their choice.

So, what key labels do farmers need to pay attention to when buying vegetable seeds?

Cao Gaoyi, a teacher who organized the student survey, said: "the date of production; the coated seeds should pay attention to the toxic marks of the coating agent; identify famous brands, choose and buy large companies and famous brands, and ensure the quality of seeds." "the pros and cons, authenticity and falsehood of seeds can be distinguished by these tags." Cao Gaoyi said: first of all, it depends on whether the basic contents of the label are fully marked, including crop type, seed category, and variety name; seed producer and operator information, including seed producer and operator name, seed production and operation license number, address of registration place and contact information; quantity index, net content; testing date and quality assurance period; variety suitable planting area and planting season; quarantine certificate number; information code. Secondly, we should also pay attention to whether the seed packaging is relatively old, if the packaging is relatively old, it may be old seeds, we should pay special attention when buying.
