Agricultural organic fertilizer and preparation method thereof

Abstract

The invention discloses agricultural organic fertilizer. The agricultural organic fertilizer consists of the following raw materials in percentage by weight: 30-45 parts of fowl manure, 15-25 parts of cow dung, 12-25 parts of pig manure, 10-13 parts of peat soil, 15-20 parts of straw ash, 8-10 parts of sawdust, 2-4 parts of formic acid, 5-8 parts of animal bone meal, 6-8 parts of egg shell powder, 3-5 parts of gypsum powder, 2-4 parts of calcium hydrogen phosphate and 0.5-0.8 part of an EM inoculant. Furthermore, the invention discloses a preparation method of the agricultural organic fertilizer. The agricultural organic fertilizer, compared with the prior art, has the following advantages that the agricultural organic fertilizer overcomes shortcomings of chemical fertilizer and conventional agricultural fertilizer, and realizes comprehensive treatment of waste to turn waste into wealth; and the agricultural organic fertilizer can protect soil. The organic fertilizer preparation method is simple and easy to operate, relatively short in fermentation time, wide in raw material source, low in cost, and quite remarkable in both social benefit and economic benefit.

Description

technical field [0001] The invention relates to the technical field of agricultural fertilizers, in particular to an agricultural organic fertilizer and a preparation method thereof. Background technique [0002] my country is a large agricultural production country. With the high utilization of fertilizers, the requirements for fertilizers are constantly increasing. At present, a large amount of inorganic fertilizers are used, which seriously leads to the increase of harmful substances in crops, poor quality, and incomplete nutrition. Secondly, the soil is prone to Hardening, poor drought resistance, and poor water retention performance, which seriously affects the normal growth of crops and poor economic benefits. [0003] Disposal of domestic waste is one of the keys to environmental protection. The current state of social development is that with the gradual improvement of people's living standards, more and more domestic waste is produced. Citizens require the harmless ...

Problems solved by technology

[0004] Although traditional farm organic fertilizers do not have the disadvantages of inorganic fertilizers, they are piled up in front of and behind houses or on both sides of roads for a long time. The natural fermentation time is long, and it affects environmental sanitation, pollutes the air, causes harmful bacteria to multiply, and is harmful to the health of humans and animals. In addition, farmyard manure is time-consuming and labor-intensive when accumulating manure and fertilizing, and the amount is large, and the variety is single and the nutrients are not complete.
