Problems solved by technology

At present, film covering agents on the market, such as the invention patent application of Chinese Patent Application No. 200610010590.1, disclose a soil film forming agent, which is prepared by using polyacrylic acid aqueous solution, wood acetic acid and water to improve the water retention performance of soil , to maintain the ground temperature, but it cannot solve the problem of covering the seedling trays, the strength is not enough during transportation, and there are many damages caused by upside down
For another example, all kinds of seed coating film-forming agents on the market are not suitable for the overall film covering of seedling trays.

Abstract

The invention discloses a film coating agent for a seedling tray. The film coating agent is prepared by using 1-1.2 kg of film forming components, 15-25g of auxiliary components and 10-12kg of water, wherein the film forming components are any one or more of potassium fulvic acid, modified starch and carboxymethylcellulose; and the auxiliary components are any one or more of copper sulfate water solution, 80% Bordeaux mixture wettable powder and 75% chlorothalonil wettable powder. The film coating agent for the seedling tray has the advantages the process is simple, the component proportions are reasonable, the film coating agent is convenient to use, the problem of sealing the seedling tray can be effectively solved, the insect pests can be prevented and the moisture is preserved.

Description

Technical field: [0001] The invention relates to the technical field of agricultural medicaments, in particular to a film coating agent for seedling trays and its preparation and use methods. Background technique: [0002] Breeding floating tray is commonly called as seedling tray, and it is foam product, and is rectangular, is provided with some apertures on it, and packs matrix (being soil) and seed in aperture, is used for seedling raising operation. This method of raising seedlings is one of the commonly used methods at present. After the current seedling trays are filled with substrate and sown, long-distance transportation cannot be realized. Even if mechanical automation lines such as tray loading and seeding are formed, the produced seedling trays will cause the substrate and seeds in the trays to scatter due to long-distance transportation bumps. Then after entering the seedling raising stage, problems such as uneven emergence and hole seedlings have been caused, w...
