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.

Description

technical field [0001] The invention relates to a fertilizer, in particular to a special coated fertilizer for fruit trees; the invention also relates to a manufacturing method of the coated fertilizer. Background technique [0002] Fruit trees are perennial plants, which are usually planted and grow in the same place for many years. They need a large amount of elements, medium and trace elements throughout the growth cycle. This has long been confirmed by theory and practice. The combination of large, medium and trace elements When it is made into a compound (mixed) fertilizer, its efficacy is better than that of simple fertilizers, fertilizers containing only macroelements or fertilizers containing only trace elements, which has also been verified in production. However, even if compound (mixed) fertilizers are used, there are still problems such as large investment, high fertilizer requirements, short fertilizer efficiency, large labor requirements, and unreasonable use o...
