Special slow-release fertilizer for stephania epigaea and preparation method thereof

Abstract

The invention discloses a special slow-release fertilizer for stephania epigaea and a preparation method thereof. The slow-release fertilizer comprises the following raw materials in parts by weight: 50 to 80 parts of urea, 40 to 50 parts of potassium phosphate, 30 to 45 parts of potassium dihydrogen phosphate, 5 to 15 parts of magnesium sulfate, 2 to 3 parts of zinc sulfate, 4 to 6 parts of sodium selenite, 3 to 5 parts of borax, 1 to 2 parts of ammonium molybdate, 4 to 7 parts of calcium superphosphate, 10 to 15 parts of tea bran, 20 to 30 parts of bagasse, 10 to 20 parts of expanded vermiculite, 15 to 20 parts of a coating agent and 0.1 to 0.5 part of a plant growth regulator, wherein the coating agent is montmorillonite and starch; the plant growth regulator is one or freely proportional mixture of two of sodium nitrophenolate and diethyl aminoethyl hexanoate. The slow-release fertilizer for the stephania epigaea has the advantages of complete nutrition, good slow-release effect, high utilization rate, low cost, simple preparation, no environmental pollution and the like, as well as good economic benefits; the yield of the stephania epigaea can be remarkably improved, the alkaloid content can be increased, and the large-scale production of the stephania epigaea can be well promoted.

Problems solved by technology

[0003] Because the ground is not happy to grow in limestone areas, between fences or rocky hills and thorny bushes, the nutrients in the soil are less, and it mainly depends on natural growth, resulting in slow growth, low product yield and quality.

At present, when the planting area is not allowed to be fertilized,
