New technology for making organic fertilizer by straw
2024-08-06 14:01:14
As we all know, crop straw can produce ecological organic fertilizer, which has attracted the attention of many researchers. China's crop straw resources are very rich, and the development and utilization of this resource has broad prospects. In recent years, the researchers of Baoding Tianyuan Fertilizer Research Institute have made great efforts to improve the straw fertilizer to a new level by using the combination of physical, chemical and biological technologies. From straw crushing to fermenting into ecological organic fertilizer, only 2 In the week, he is a national leader in straw fertilizer technology. The specific operating procedures are as follows:
1. Selection of fertilizer sites. The fertilizer-making site should choose a flat roof, a house near the water source, an idle house, a field or a roadside. In the winter, you should choose the leeward sun.
2. Preparation of fertilizer materials. (1) Crop straw 100% (corn straw should be coarsely crushed, wheat straw can be used directly). (2) Kendall Green special fast fermenting agent 0.1%. (3) Cottonseed cake or bean cake powder 1%-2% (no cottonseed cake, bean cake powder can be replaced by human feces with 0.5%-1% or 10%-20% urea).
3. Technical points of fertilizer production. (1) Drinking feet: It means that the crop straw must be thoroughly poured with water. Fresh crop straws may be watered or not watered depending on their wet and dryness. (2) Mix well: Mix the cake powder with the special fast fermenting agent first, and then spread it evenly on the surface of the straw after the water is poured. Use a spade and other tools to turn over the mix and stack them into strips that are 2 meters wide and 1 meter high. (3) Cover tight: In order to keep water, protect fertilizer, keep warm, and prevent rain, the evenly mixed straw should be covered with plastic cloth immediately.
4. The process of straw septicization. The change from the temperature of the straw stack can be roughly divided into the following stages: (1) the warming stage. That is, from the normal temperature to the temperature of about 50 ° C, generally only one day. (2) High temperature stage. That is, from 50 ° C to 70 ° C stage, generally only 2 days. (3) Cooling stage. That is, after 1-2 weeks of continuous high temperature, the temperature is lowered. At this time, the straw fertilizer production process is basically completed, and it can be directly used in various crops as a base fertilizer when dried or not dried.
