Problems solved by technology

Straw contains a large amount of organic matter, nitrogen, phosphorus, potassium and trace elements. It is one of the important organic fertilizer resources for agricultural production. The stored nutrient content is equivalent to a quarter of my country's current chemical fertilizer application. The most abundant and cheapest renewable resources on the earth are not fully utilized due to the increase in index and the transfer of rural labor force. Except some straws are used as feed and paper-making raw materials, most of the plant straws are either burned or discarded, and the utilization rate is ex

Embodiment Construction

[0019] Raw materials are prepared according to the following proportions: 60%wt of plant straw with a water content of 30-35%, 20%wt of edible mushroom residue, 14%wt of cake, 5%wt of calcium magnesium phosphate fertilizer, and 1%wt of cellulolytic bacterial agent. Among them, the plant straw is the mixed straw of corn stalks and cotton stalks, the edible fungus residue is the discarded culture medium after planting Flammulina velutipes, the cake is rapeseed cake, which is a by-product after pressing rapeseed oil, and the cellulose decomposing bacteria agent is the content of the invention Bacteria described in.

[0020] Raw materials are processed according to the following process:

[0021] 1. Grinding plant straw with a moisture content of 30-35% with a straw crusher to obtain material A;

[0022] 2. Remove the film of the edible fungus residue, mash and add the formula amount of calcium, magnesium and phosphorus to obtain material B;

[0023] 3. Pulverize the rapeseed ca...

Abstract

The invention provides a method for producing an organic fertilizer from plant straws by aerobic fermentation. According to the method, the plant straws are used as a major material and appropriate portions of edible fungi residue, seed cake, calcium magnesium phosphate and cellulose decomposition bacteria are added to carry out aerobic fermentation of the mixed compost. By applying modern high-temperature aerobic fermentation of the compost, the method comprises the procedures of pre-treatment of raw materials, high-temperature aerobic fermentation, aging, pulverizing, granulating, drying and screening. The method employs a way of fermentation that is different from the traditional process, specifically, high-temperature aerobic fermentation of the compost, to produce the organic fertilizer.

Description

technical field [0001] The invention belongs to the technical field of organic fertilizers, in particular to a method for producing organic fertilizers by fermenting plant stalks. Background technique [0002] my country is a large agricultural production country, with a large area of ​​crops, and a large amount of crop stalks are produced after the crops are harvested. The annual total output reaches more than 700 million tons and increases at a rate of 1.3%. Straw contains a large amount of organic matter, nitrogen, phosphorus, potassium and trace elements. It is one of the important organic fertilizer resources for agricultural production. The stored nutrient content is equivalent to a quarter of my country's current chemical fertilizer application. The most abundant and cheapest renewable resources on the earth are not fully utilized due to the increase in index and the transfer of rural labor force. Except some straws are used as feed and paper-making raw materials, most...
