Coated fertilizer for fruit trees and mfg. method

Abstract

This invention relates to a kind of coated fertilizer specially for fruit trees, which comprises 25~35 shares of urea, 20~30 shares of calcium superphosphate, 23~33 shares of fertilizer of calcium and magnesium phosphate, 6~9 shares of potassium sulphate, 0.7~1.8 shares of ferrite sulphate, 0.7~1.8 shares of borax, 0.7~1.8 shares of manganese sulphate, 0.7~1.8 shares of copper sulphate, 0.2~3 shares of zincum sulphate, 0.7~1.8 shares of ammonium molybdate and paraffin coating materials weighing 4~10% of the total mass of the raw materials above mentioned. For preparation, copper sulphate, ferrite sulphate, zincum sulphate and manganese sulphate are pulverized. Half of the fertilizer of calcium and magnesium phosphate is mixed copper sulphate, ferrite sulphate, borax and manganese and stirred, and the rest raw materials are then mixed and stirred. The homogeneously stirred materials are spindly particles due to a ball-like mechanism and paraffin weighing 4~10% of the fertilizer is melted and used for coating with a coating machine. This invention has the advantages of low fertilizer cost, long fertility persistence, simple production and small investment. The fertility can be effective for as long as one year and by continuous fertilization for two to three years, no fertility shortage will be observed even if stopping fertilization in the following year.

AI Technical Summary

Benefits of technology

This patented technology allows for multiple element coatings on different types of fertils with specific nutrients needed by plants like fruits or vegetables during their growing period without stopping any further use over an entire season due to lacking certain chemicals at once. These elements help improve crop yields while also increasing its overall healthiness through reducing nitrogen loss from soil erosion caused by excessive water usage. Overall, these technical benefits make farmers more efficient ways to produce high-quality crops.

Problems solved by technology

Technological Problem: Compounds like fruits have difficulty growing within certain areas due to their limited nutrients needed during different stages of development. These complex mixtures can be difficult to store over time without losing important components from surrounding environments. Additionally, these compositions may contain harmful substances causing environmental concerns when released on land after being applied onto crops. Therefore, finding ways to improve the performance of existing chemicals while reducing costs associated with producing them remains an issue.
