Manufacturing process and technology of organic fertilizer for processing straw
Straw is one of the raw materials in the production of organic fertilizer, which is different from the manufacturing of NPK fertilizer and the treatment of livestock manure. There are special requirements and characteristics when straw is treated by organic fertilizer manufacturing process, which needs composting processing. Production technology of organic fertilizer for processing straw 1. Traditional straw composting The traditional straw composting technology has the advantages of long fermentation time, poor fermentation effect and simple equipment, which is suitable for small-scale application. The method of straw fermentation is as follows: firstly, the straw is crushed with a pulverizer, but not excessively crushed, and the factors such as moisture, carbon nitrogen ratio and pH value are adjusted. The optimum ratio of carbon to nitrogen is 25:1. Therefore, adjusting the ratio of carbon and nitrogen in composting materials is an effective measure to accelerate the matur...
