Multifunctional bio-organic fertilizer and preparation method thereof

Abstract

The invention discloses a multifunctional bio-organic fertilizer and a preparation method thereof, and relates to the technical field of agricultural fertilizers. The multifunctional bio-organic fertilizer is prepared from the following raw materials in parts by weight: 40-60 parts of forestry and agricultural residues, 10-16 parts of active humic acid, 5-15 parts of degreased tea-seed pancake, 0.5-1.5 parts of expanded vermiculite, 0.2-0.8 part of abscisic acid, 0.2-0.8 part of zymophyte, 0.2-0.8 part of beneficial bacterium, 0.2-0.8 part of degrading bacteria, 5-9 parts of urea, 8-12 parts of calcium magnesium phosphate fertilizer, 4-8 parts of potassium sulfate, and 0.5-1.5 parts of medium and trace element. The multifunctional bio-organic fertilizer has the characteristics that the nutritional elements for plant growing are contained; the organic substances are rich; in addition, the contaminated oil can be remediated; the soil structure can be activated; the multifunctional bio-organic fertilizer is applicable to the planting of crops such as rice of southern China, vegetables, watermelon, tobacco, fresh ginger, rape and tea, fruits such as naval orange, grapefruit and pear, garden nursery stock and flowers.

Description

technical field [0001] The invention relates to the technical field of agricultural fertilizers, in particular to a multifunctional bio-organic fertilizer and a preparation method thereof. Background technique [0002] Since the 1970s, my country's agricultural production has used chemical fertilizers for a long time, resulting in soil heavy metal pollution, soil acidification and compaction, soil fertility decline, rampant pests and diseases, and decline in the yield and quality of agricultural products, seriously restricting the sustainable development of my country's agriculture. In recent years, the habits of farmers in my country have undergone good changes in the use of fertilizers, and the proportion of organic fertilizers used in agricultural production has continued to increase. However, the existing organic fertilizers on the market generally have a single function, and do not degrade heavy metals and antibiotics on raw materials such as poultry manure, which leads...

Problems solved by technology

However, the existing organic fertilizers on the market generally have a single function, and do not degrade heavy metals and antibiotics on raw materials such as poultry manure, which leads to further aggravation of heavy metal and antibiotic pollution in the soil, and the nitrogen, phosphorus, and potassium content of the existing organic fertilizers on the market Not high, or lack of trace elements, nutrition is extremely incomplete, it is difficult to meet the nutrition needed for plant growth
