Fertilizer production line technology using straw to produce organic fertilizer

Method for making dead leaves organic fertilizer production line:


1. Prepare materials and add bacteria. 1 to 1.5 tons of dried leaves and withered grass, about 2.5 to 3.5 tons of fresh material, (it is best to break up the fallen leaves and withered grass first) with 1 kg of fertilizer starter. The fertilizer and starter should be mixed with rice bran (or corn flour, wheat bran) at a ratio of 1: 5 to 10 before use. The C / N ratio of the fermentation material should be maintained at 25-30. The C / N of the fallen leaves and withered grass is too high, so it should be adjusted. Therefore, one ton of dead grass leaves should be added with one kilogram of urea (or 100 kilograms of livestock and poultry manure).

2. Build materials. The prepared materials should be piled while spreading bacteria. The pile height and volume should not be too short or too small. Requirements: The pile height is 1.5 to 2 meters, the width is 2 meters, and the length is 2 to 4 meters. 3. Regulate moisture. The moisture of the fermentation material should be controlled at 60 to 65%. Moisture judgment: Hold the material tightly with your hand, see the watermark in your fingers, but do not drip. Fermentation is slow with less water, and aeration is poor with more water, which can also cause “septic bacteria” to work and produce odor.

3. Mix well and ventilate. Fertilizer fermentation agent requires good (aerobic) fermentation. During the operation process, the oxygen supply measures should be increased to achieve uniform mixing, diversion and ventilation. Otherwise, anaerobic fermentation will cause odor and affect the effect. At this stage, a compost turning machine can be used for flipping to provide oxygen.

4. Fermentation is complete. Generally after 48 hours of material accumulation, the temperature rises to 50-60 ° C, and on the third day it can reach above 65 ° C. It should be overturned once at this high temperature. Generally, high temperatures above 65 ° C occur twice during the fermentation process. , Overturning twice can complete the fermentation, and normal fermentation can be completed within a week. The material was dark brown, and the temperature began to drop to normal temperature, indicating that the fermentation was complete.
