Abstract

The invention relates to a chitosan sustained release microsphere fertilizer loaded with thiophanate-methyl for tomatoes, which is characterized by being prepared from the following raw materials: chitin, sodium hydroxide, thiophanate-methyl, propiconazole, acetone, sodium dodecyl benzene sulfonate, acetic acid, polyethylene glycol diglycidyl ether, cyclohexane, epoxy chloropropane, glutaraldehyde, petroleum ether, isopropyl alcohol, lithopone, coal ash, attapulgite, plant ash, potassium pyrophosphate, sodium alga acid, hexamethylene diisocyanate, triethylene diamine, human and animal excreta, urea, monocalcium phosphate, zinc sulfate, and appropriate amount of water. The fertilizer prepared by the invention integrates increased production, high efficiency, long effect, quality improvement, and soil improvement into a whole, and has the advantages of low cost, simple process, no residue, no pollution, labor and time saving when being applied, and the like.

Description

technical field [0001] The invention belongs to the field of pesticides and fertilizers, in particular to a thiophanate-methyl-loaded chitosan slow-release microsphere fertilizer for tomatoes and a preparation method thereof. Background technique [0002] Different types of fertilizers and pesticides are required at each stage of the growth process of crops. At present, basal fertilizers are generally applied before land cultivation, while diseases and insect pests are easily generated in the roots during the germination process of crops, and then they are spread in the soil to treat them. The powder not only increases the labor intensity, but also causes certain damage to the roots of the crops; in the second growth period such as jointing and grouting, topdressing fertilizers and pesticides are required, which further increases the labor intensity. [0003] Medicated fertilizer is a compound of pesticides and fertilizers produced by mixing pesticides and fertilizers in a c...
