Abstract
Disclosed is a chitosan sustained releasing microsphere fertilizer for effective prevention and treatment of tomato fruit cracking. The chitosan sustained releasing microsphere fertilizer is characterized by being prepared from raw materials of chitin, sodium hydroxide, calcium chloride, zinc sulfate, copper phosphate, acetic acid, glycerin monostearate, cyclohexan, folic acid, glutaraldehyde, petroleum ether, isopropanol, soybean straw, maize straw, livestock faeces, river sludge, urea, monopotassium phosphate, sodium dihydrogen phosphate, and an appropriate amount of water. The prepared chitosan sustained releasing microsphere fertilizer has the integrated characteristics of improving yield, being efficient, having long-acting effects, improving fruit quality and improving soil; meanwhile, the chitosan sustained releasing microsphere fertilizer has the advantages of being low in cost, simple in technology, having no residue and no pollution, saving labor and time during construction and the like.
Description
technical field [0001] The invention belongs to the field of pesticides and fertilizers, and in particular relates to a chitosan slow-release microsphere fertilizer for effectively preventing tomato cracking disease and a preparation method thereof. Background technique [0002] The types of fertilizers and pesticides required at each stage of the crop growth process are different. At present, the basal fertilizer is generally used before the land is cultivated, and it is easy to cause diseases and insect pests in the roots during the germination process of the crops, and then spread them in the soil to treat the diseases and insect pests The high-grade medicinal 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, fertilizers and pesticides need to be topdressed, which further increases the labor intensity. [0003] Medicinal fertilizer is a compound agent of pesti...
