Novel organic fertilizer and preparation method thereof

Abstract

The invention relates to the field of fertilizers, and in particular, relates to a novel organic fertilizer and a preparation method thereof. The novel organic fertilizer comprises the raw materials: 10-20% of mushroom dregs, 5-15% of sawdust, 20-30% of bean dregs, 16-25% of plant ash and 25-35% of sheep manure. The preparation method comprises the steps: weighing and mixing the mushroom dregs, the sawdust, the bean dregs, the plant ash and the sheep manure according to the weight ratio, and feeding the mixture into a fermentation tank; and adding a leavening agent, fermenting for three times, feeding into an aging area for aging, and finally crushing and sieving to obtain the novel organic fertilizer. The raw materials are all from waste residues, waste materials and excrement, the cost is low, the effects of environmental protection and resource recycling are achieved, the organic fertilizer with the good effect is produced, resource waste is reduced, and high environmental protection significance and economic significance are achieved. The raw materials are fermented by adopting a three-time fermentation process, thorough decomposition is ensured, and the inactivation rate of roundworm eggs, escherichia coli, grass seeds and infectious microbes is 100%.

Description

technical field [0001] The invention relates to the field of fertilizers, in particular to a novel organic fertilizer and a preparation method thereof. Background technique [0002] Agriculture is the foundation of other industries such as industry and service industry. The rise and fall of agriculture is a major event that directly affects the national economy and people's livelihood. At present, the world is facing severe problems of population increase and environmental degradation. As a large agricultural and populous country, this problem is particularly prominent in China . [0003] With the improvement of the quality of life, people pay more and more attention to the safety of food, and the demand for pollution-free, safe and hygienic green food is increasing day by day. In the production of crops, fertilizer plays a very important role. In recent years, agricultural production basically relies on chemical fertilizers that are conveniently applied and produced indust...

AI Technical Summary

Problems solved by technology

In recent years, agricultural production basically relies on chemical fertilizers that are conveniently applied and produced industrially. As a result, the soil structure is destroyed, the buffer capacity is greatly reduced, and it is easy to cause fertilizer damage; the ecological environment deteriorates, the production potential decreases, and more seriously, the soil and Agricultural products are polluted, agricultural costs increase, and a lot of resources are wasted. This is very different from the country's initiative to develop ecological agriculture and realize pollution-free production.

[0004] At present, the organic fertilizer that most farmers know is farmyard manure in the traditional sense. Although farmyard manure has many advantages, farmers are not willing to use it because of its dirty, smelly and time-consuming production, transportation and application. Different from the formula, in order to save costs, some companies use relatively inferior raw materials containing strong acid and alkali, and even use raw materials containing heavy metals such as sludge and sediment. The organic fertilizer produced by them will not only fail to improve the soil, but will give Soil poses a hazard
