Biological bacterial composite organic fertilizer and preparation method thereof

Abstract

The invention discloses a biological bacterial composite organic fertilizer and a preparation method thereof. The composite organic fertilizer comprises following raw materials in percentage by weight: 10 to 60% of turf soil, 5 to 60% of furfural residue, 4 to 40% of humic acid, 0.1 to 10% of fruit enzyme compounded biological bacteria, and 0.1 to 8% of water absorbing resin. The preparation method comprises following steps: (1) mixing raw materials; (2) carrying out composting fermentation; (3) grinding and sieving; and (4) granulating and packaging. The raw materials cooperate with each other to generate a synergistic effect. The fertilizer increases the output of crops, no chemical fertilizer is used, the cost is reduced, and moreover, the physical properties and fertilizing performanceof soil are improved. During the preparation process, fruit enzyme compounded biological bacteria are added, the nitrogen fixing and growth promoting effects are guaranteed, water absorbing resin isadded to maintain the water and fertilizer of soil; due to added turf soil, furfural residues and humic acid, the contents of elements required for the growth of plants such as nitrogen, phosphorus, potassium, and the like are not less than 5%; and the obtained crops are natural and nutritional.

Description

technical field [0001] The invention relates to the technical field of fertilizer production, and more specifically relates to a biological bacteria compound organic fertilizer and a preparation method thereof. Background technique [0002] At present, growers do not have a clear understanding of land salinization and soil flattening diseases and insect pests. They have developed a habit of relying on chemical fertilizers and pesticides for land cultivation, and the use of animal manure cannot be sterilized. Harmful bacteria in manure cause land diseases The spread of the plant seriously affects the yield and quality of the plant. At the same time, the osmotic loss of different degrees of nitrogen, phosphorus and potassium not only causes crop stress resistance, saline-alkali land, but also causes serious soil compaction, which has already hindered agricultural production and crop yield increase. [0003] Therefore, how to provide a kind of biological bacteria compound or...
