Problems solved by technology

In recent years, there are also records of seed coating agents synthesized by biological bacteria, alkaloids and flavonoid glycosides in my country, but their efficacy is reduced due to the influence of temperature and humidity, so they cannot be widely used in production

Embodiment 1-3

[0024] Prepare the seed dressing:

[0025] a, get the raw material according to the ratio listed in Table 1, crush through a 35 mesh sieve and cut into 2 cm long sections for subsequent use.

[0026] b. Take 1 part of the raw material prepared in the step a by weight and mix it with 20 parts of water, put it into a cooking tank and heat it under reduced pressure until the liquid boils, and then heat-preserve and extract for one hour, filter, discard the residue, and take the extract for subsequent use;

[0027] c. Pack the extract into a concentration tank and concentrate to saturation to obtain a concentrate;

[0028] D, in the concentrated solution that step c obtains, slowly add the 1% mass percent concentration of concentrated solution weight ratio and be 37% hydrochloric acid, the molybdic acid of 0.1% and the mass percent concentration of 0.2% are phosphoric acid, stir, then be warming up to liquid boiling , keep warm for 40 minutes, stir once every 20 minutes, stop th...

Abstract

The invention discloses a seed-dressing agent as well as a preparation method and application thereof. The seed-dressing agent comprises effective ingredients extracted from anemone vitifolia, radix sophorae flavescentis, golden cypress, folium artemisiae argyi, angelica sinensis and thunder god vines. The seed-dressing agent is simple in component, convenient to use, free from pollution and residue on grain and economic crop seeds, and low in toxicity to people and livestock and has the effects of mouse preventing, insecticide, sterilization and crop nourishing; the preparation method is simple, the flow is easy to control, the operation is convenient and easy, the yield of effective ingredients of materials is high, the components of the seed-dressing agent are stable, and the seed-dressing agent is easy to store and use. The invention also provides a using method of the seed-dressing agent. In the method, seeds are mixed with the seed-dressing agent after the agent is diluted, and the application is convenient.

Description

technical field [0001] The invention relates to a seed dressing agent, in particular to a plant raw material seed dressing agent, a preparation method and application technology of the seed dressing agent. Background technique [0002] According to the statistics of the Food and Agriculture Organization of the United Nations in the late 1980s, the grain and economic crops in the world caused the shortage or loss of up to 20%-50% of the field due to the seeds being attacked by rodents, diseases and insect pests, forcing the world to produce seed coatings and seed dressings every year. The annual output of pesticides or seed soaking agents reaches 500,000-800,000 tons, which are mainly chemical pesticides. Their main raw materials are synthesized from chemical pesticides with high toxicity, high toxicity and long residual period, and they made certain contributions to agricultural production during 1980-2006. At the beginning of the 21st century, when the highly toxic, highly...
