Special organic-inorganic compound fertilizer for peanut and preparation method thereof

Abstract

The invention discloses a special organic-inorganic compound fertilizer for peanut. The special organic-inorganic compound fertilizer for peanut comprises the raw materials in parts by weight as follows: 80-110 parts of urea, 25-50 parts of urea-ammonium chloride, 35-55 parts of diammonium phosphate, 390-460 parts of calcium magnesium phosphate fertilizer, 50-120 parts of potassium chloride, 150-300 parts of brown coal, 20-30 parts of ammonium bicarbonate, 30-50 parts of nitrohumic acid, 17-26 parts of zinc-amino acid chelate, 8-12 parts of borax, 1-2 parts of ammonium molybdate, 18-24 parts of adhesive, 20-40 parts of porous inorganic matter and 30-60 parts of filler. The fertilizer is prepared by effectively mixing the organic fertilizer and the inorganic fertilizer, the fertilizer is used for effectively raising the content of the protein and the fatty acid in the peanut kernel and effectively raising the yield of the peanut, the ratio is reasonable and the nutrition is complete for raising the oil content of the peanut and improving the crop quality.

Description

technical field [0001] The invention relates to the technical field of fertilizers, in particular to a special organic-inorganic compound fertilizer for peanuts and a preparation method thereof. Background technique [0002] Peanut is an economic crop, which occupies an important position in our country's national economy. It is the main source of food oil for our people, the main source of plant protein for human beings, an important raw material for the food and pharmaceutical industries, and an important agricultural product for my country's export earnings. For a long time, the agricultural production practice has shown that peanuts use too much nitrogen fertilizer, the growth is vigorous but the yield is low, the single pome fruit is more, the double pome fruit is less, and the yield is low. Therefore, the production of peanut special fertilizer will become the main fertilizer that will provide high peanut yield. It is not only the product of scientific experiments accu...

AI Technical Summary

Problems solved by technology

However, judging from the development status of my country's agricultural fertilization, there are still the following problems to be solved urgently: First, most of the agricultural fertilizers are still based on general-purpose formulas such as nitrogen-phosphorus-potassium 15-15-15, with the same amount of nitrogen, phosphorus and potassium. It is impossible to apply the same nitrogen, phosphorus and potassium to crops, resulting in a lack of certain nutrients and a waste of certain nutrients

[0005] In view of the unreasonable ratio of nitrogen, phosphorus and potassium that still exists in the special fertilizer for peanuts, appropriate amount of trace elements are not added, and the reasonable combination of nitrogen, phosphorus, potassium, calcium and trace elements is ignored, which cannot meet the requirements of peanuts for major nutrients , resulting in a serious imbalance of soil nutrients, leading to poor nutrient supply in various stages of peanut growth and development, not only difficult to increase yield, poor quality and taste of peanut pulp, lower oil content, and a series of problems that do not meet the requirements of balanced fertilization and formula fertilization, etc.
