Problems solved by technology
[0003] At present, the promotion of blended fertilizers is very prosperous in the world. It is characterized by high fertilizer efficiency, low price, and strong pertinence. In Japan, there is one fertilizer distribution station within a radius of 50 kilometers, and each fertilizer distribution station has as many as eight There are more than one hundred formulas; and although the technology of soil testing and formula fertilization has been popularized in my country for a long time, the actual situation is "push and cannot be opened"; the reason is that farmers do not know the characteristics of chemical fertilizers, let alone the law of fertilizer needs of crops, so it is difficult to produce and prepare blended fertilizers

The invention discloses a formula of coconut tree special-purpose mixed fertilizer prepared by matching of calcium-magnesia-phosphate powder and fertilizer sources such as single superphosphate particles and urea. According to a coconut tree fertilization requirement rule, calcium-magnesia-phosphate fertilizer powder and fertilizer sources such as single superphosphate particles and urea are matched so that a calcium-magnesia-phosphate film is formed on surface of the particle and thus deliquescence of single superphosphate and urea because of direct contact is prevented. After being used in soil, the coconut tree special-purpose mixed fertilizer has effects of reducing phosphorus immobilization and slowly releasing nitrogen. The calcium-magnesia-phosphate fertilizer contains medium trace elements necessary for crop growth and is ideal multi-element compound fertilizer. A preparation method of the coconut tree special-purpose mixed fertilizer comprises matching 0.9-1.1 parts of high-quality calcium-magnesia phosphate fertilizer powder with 3.4-3.6 parts of urea, 0.4-0.6 parts of monoammonium phosphate, 2.4-2.6 parts of single superphosphate particles and 2.4-2.6 parts of potassium chloride, carrying out dry-mixing stirring and carrying out split charging by bags. The coconut tree special-purpose mixed fertilizer can be marketed and be used for production. The coconut tree special-purpose mixed fertilizer contains 39% of the total nitrogen, phosphorus and potassium nutrients and has a nitrogen-phosphorus-potassium ratio of 16: 8: 15.
Description
[0001] design field [0002] The invention relates to the field of soil testing formula fertilization and chemical fertilizers, in particular to a special blend fertilizer formula for coconut trees produced by using calcium magnesium phosphorus powder compatible with granule common calcium and other fertilizer sources. Background technique [0003] At present, the promotion of blended fertilizers is very prosperous in the world. It is characterized by high fertilizer efficiency, low price, and strong pertinence. In Japan, there is one fertilizer distribution station within a radius of 50 kilometers, and each fertilizer distribution station has as many as eight There are more than one hundred formulas; and although the technology of soil testing and formula fertilization has been popularized in my country for a long time, the actual situation is "push and cannot be opened"; the reason is that farmers do not know the characteristics of chemical fertilizers, let alone the law of fe...
