Abstract

The invention discloses a high-phosphorus high-potassium controlled-release fertilizer for peanuts and a preparation method of the high-phosphorus high-potassium controlled-release fertilizer, belonging to the technical field of fertilizers. The high-phosphorus high-potassium controlled-release fertilizer comprises the following raw materials in parts by weight: 20-30 parts of urea, 60-80 parts of diammonium phosphate, 30-40 parts of potassium chloride, 8-10 parts of magnesium ammonium phosphate, 8-10 parts of potassium feldspar, 1-2 parts of boric acid, 1-2 parts of ferrous sulfate, 1-2 parts of manganese sulfate, 1-2 parts of zinc sulfate, 1-2 parts of sodium molybdate, 5-10 parts of traditional Chinese medicine additive, 8-10 parts of gypsum powder and 20-30 parts of urea formaldehyde. When being used, the traditional Chinese medicine additive is decocted to form a traditional Chinese medicine extracting solution by adding water; the urea formaldehyde containing Chinese herb extracts serves as an envelope, and the gypsum powder is adhered outside the envelope; and the other raw materials are wrapped in the envelope. After being fertilized for one time, the high-phosphorus high-potassium controlled-release fertilizer meets the requirements of crops on nutrients such as nitrogen, phosphorus, potassium, calcium and sulfur in the entire growth period. Meanwhile, the high-phosphorus high-potassium controlled-release fertilizer can be used for increasing the setting ratio and the yield by above 15% and meanwhile greatly reducing the occurrence rate of stem rots, root rots and the like of peanuts.

Description

technical field [0001] The invention relates to a high-phosphorus and high-potassium slow-release fertilizer for peanuts and a preparation method thereof, belonging to the technical field of fertilizers. Background technique [0002] Peanut is an important economic crop in my country and one of the main oil varieties of high-quality edible oil. There are many types of fertilizers currently used for peanut cultivation, among which the special fertilizer for peanuts mostly adopts the NPK compound fertilizer available in the market, which is mainly composed of three inorganic elements N, P, and K, which can meet the growth needs of peanuts in a short period of time. However, long-term use will cause the soil aggregate structure to be destroyed, which will easily cause soil compaction and soil hardening, thus affecting the growth of peanuts. At the same time, the utilization rate of nitrogen fertilizer in the current season in my country is only 20% to 35%, the utilization rate...
