Seed dressing agent and preparation method thereof

Abstract

The invention discloses a seed dressing agent which comprises the following components in parts by weight: 0.1-20 parts of Chinese medicinal herb preparation, 1-10 part of polyacrylate and 1-25 parts of fulvic acid, wherein the Chinese medicinal herb preparation is mainly prepared from the following components in parts by weight: 110-540 parts of mandala, 200-400 parts of rhododendron molle, 200-500 parts of indigowoad leaf, 300-600 parts of houttuynia cordata, 10-80 parts of common andrographis herb, 5-30 parts of Chinese honeylocust fruit and 50-150 parts of radix sophorae flavescentis. Theinvention adopts pure traditional Chinese medicine preparations, thereby guaranteeing that the seed dressing agent is environmental friendly, and moreover, due to the effects of the traditional Chinese medicines, the seed dressing agent has good effects of preventing diseases and resisting pests.

Description

technical field [0001] The invention relates to a crop seed dressing agent, especially an environment-friendly seed dressing agent, and a preparation method of the seed dressing agent. Background technique [0002] In modern agricultural production, the seed dressing agent commonly used by farmers is a mixed reagent used to treat the surface of seeds before sowing, in order to achieve one or more purposes such as insect control, disease control, drought resistance, and strong seedlings. Seed dressings contain insecticides or fungicides that can kill insects and prevent diseases. The insecticides or fungicides in the currently used seed dressings are chemical compounds with certain toxicity. Therefore, most seed dressings are harmful to People, animals, and the environment have certain toxic side effects and pollution, and cannot be used in the production of organic food and AA-grade green food. [0003] The seed dressings currently on the market mainly include the following...

Problems solved by technology

[0005] This kind of seed dressing also has a polymer water-absorbing agent as the main component, together with a certain amount of chemically synthesized plant growth regulators, such regulators are generally one or more of naphthalene acetic acid, indole acetic acid, or sodium binitrophenolate. Such as "Rare Earth Drought Resistant Forest and Grass Seed Coating Agent" (application number: 00102140.0), chemically synthesized plant growth regulators are chemically synthesized pesticides, so this type of seed dressing agent is not conducive to large-scale application

[0006] (2) Adding humic acid to a polymer water-retaining agent to form a seed dressing agent, such as "humate compound water-retaining agent and its preparation method" (application number: 200510090363.X), this type of seed dressing agent does not contain environmental protection Type insecticidal and bactericidal ingredients, the function is relatively single, and the production investment of this kind of seed dressing is large

[0007] (3) Seed dressing agents with humic acid (HA) as the main component, such as "Fulvic acid rare earth anti-wheat take-all seed dressing agent and its preparation method" (application number: 200710185460.6), this type of seed dressing Although the anti-drought agent has a certain drought resistance function, it does not contain polymer water-retaining agent components, and the best synergistic anti-drought effect of the two anti-drought components cannot be exerted, and the effect of anti-drought and water retention is limited.

However, this kind of seed dressing agent not only has a complicated production process, but also has high requirements for equipment and workshops, a large investment, and strict storage conditions.

Moreover, because the activity of microorganisms such as fungi has certain requirements on soil moisture, and the soil moisture in northern spring is poor, the effect of this kind of seed dressing is extremely unstable, and it does not have the function of drought resistance.
