Embodiment 1

[0013] Take 3% of yeast, 1% of lactic acid bacteria, 0.5% of protein and water, and cultivate it under anaerobic conditions for 5 days, keeping the temperature at 35°C-40°C to prepare the fermentation medium. Spray 5000kg of crop stalks with 10kg of fermentation culture solution and soak in water for 24-36h; first lay a layer of pond silt layer in the bottom of the fermentation tank with a thickness of 10-20cm; lay the first layer of 5000kg of crop stalks and spray 100kg of lime water; Pave the second layer of fine soil 2500kg and the third layer of manure 1000kg, cover the outer layer with mud without ventilation; turn the pile once every 5-10 days, spray 100kg of fermentation culture solution, and cover the outer layer with mud for 5-10 days.

Abstract

The invention relates to a crop straw fertilizer preparation method which is characterized by mainly involving 60% of crop straw, 10% of animal manure, and 30% of fine soil. The particular preparation method comprises the following steps: spraying a fermentation culture solution on crop straw, soaking the crop straw in water for 24-36 hours; firstly laying a pond sludge layer with a thickness of 10-20 cm on the bottom of a fermentation pool, then laying a first layer of 60% of the crop straw, spraying a little lime water, laying a second layer of 30% of fine soil and a third layer of 10% of animal manure, covering the outer layer with sludge in an air-tight manner for sealing; pile-turning every 5-10 days, spraying the fermentation culture solution, and covering the outer layer with sludge in an air-tight manner for sealing for 5-10 days. The method of the invention has the advantages that waste straw is used reasonably, the water-logged composting period and the pile-turning frequency are reduced, few nutritive elements are lost, and the components of crop straw are brought into full play.

Description

technical field [0001] The invention relates to a fertilizer retting method, in particular to a method for making fertilizer from crop stalks. technical background [0002] Crop straw is rich in nitrogen, phosphorus, potassium, calcium, magnesium and organic matter, etc. It is a multi-purpose renewable biological resource, especially suitable for retting, and the fertilizer has comprehensive nutrition. It is a cheap and effective organic fertilizer in rural areas. Material. At present, the traditional composting method takes a long time, and the number of times of turning over is relatively frequent, and the method of using strain fermentation is relatively high in cost and loses more nutrients. Contents of the invention [0003] The present invention provides a method for making fertilizer from crop stalks, which solves the above disadvantages and reduces the composting cycle and the number of turning times. [0004] A method for making fertilizer from crop stalks, char...
