Organic fertilizer and its preparing process

Abstract

The invention discloses an organic fertilizer and making method, which comprises the following parts: 40-70% poultry manure, 15-30% peanut slag and 15-30% peat. The making method comprises the following steps: (1) blending each raw material evenly; (2) fermenting under 25-30 deg.c for 3-10d; drying.

Description

technical field [0001] The invention relates to an organic fertilizer with high fertilizer efficiency and convenient transportation and fertilization and a preparation method thereof. Background technique [0002] At present, a large amount of chemical fertilizers are used in the cultivation of food crops and economic crops, but long-term use of chemical fertilizers will cause soil compaction and increase in pests and diseases; and the utilization rate of chemical fertilizers is low, energy consumption is high, and the loss is serious, and it will also cause a large amount of vegetables, melons and fruits to exist. Therefore, in order to restore soil fertility and ecology, reduce the use of chemical fertilizers as much as possible, and promote the use of organic fertilizers or compound fertilizers is a common understanding.

Problems solved by technology

[0002] At present, a large amount of chemical fertilizers are used in the cultivation of food crops and economic crops, but long-term use of chemical fertilizers will cause soil compaction and increase in pests and diseases; and the utilization rate of chemical fertilizers is low, energy consumption is high, and the loss is serious, and it will also cause a large amount of vegetables, melons and fruits to exist. Therefore, in order to restore soil fertility and ecology, it is common knowledge to reduce the use of chemical fertilizers and promote the use of organic fertilizers or compound fertilizers.

[0003] Most of the existing organic fertilizers are compound fertilizers composed of adding an appropriate amount of organic matter to chemical fertilizers. The disadvantage is that the total nutrient content of this fertilizer is not high, and the chemical fertilizers contained in these compound fertilizers will still pollute the environment. It will still cause a certain degree of soil compaction, and the fertilizer effect cannot be fully exerted.

Not only that, the price of these compound fertilizers is high, and the investment for farmers is high, and the cost performance is not ideal

[0004] In addition, a large amount of poultry manure is produced every day in poultry breeding factories. If these poultry manures accumulate for a long time, they will not only produce unpleasant odors, but also contain harmful substances such as coliform bacteria and nematodes and pests. Timely treatment will easily breed bacteria and pests, cause environmental pollution, and affect human health. Therefore, today's poultry and livestock manure is a source of pollution that needs to be solved urgently
