Description

technical field

[0001] The invention belongs to the field of seed treatment application technology, in particular to a drought-resistant and water-retaining seed coating agent containing γ-polyglutamic acid and a preparation method thereof. Background technique

[0002] Seed coating agent is a kind of preparation used for seed coating and has film-forming properties. It can not only standardize improved varieties, but also have multiple functions such as plant protection. Its advantages are: (1) It expands and breathes in the soil without being dissolved, so that the seeds can germinate normally, and the pesticides and fertilizers can be released slowly. It can kill underground pests, prevent and control seed germs, increase the germination rate of seeds, and reduce the use of seeds. quantity and improve crop varieties. The seed coating agent is close to the seeds, with concentrated medicinal power and high utilization rate, so it saves medicine, labor and seeds compared wi...
