Biogas fertilizer is a good fertilizer with slow speed and excellent performance, which can enhance the drought resistance and antifreeze ability of crops and increase the survival rate of seedlings. Since human and animal manure and straw are sealed and fermented, a certain amount of biogas is produced while biogas is produced. The application of biogas fertilizer not only saves the spraying amount of chemical fertilizers and pesticides, but also facilitates the production of green food, but it is necessary to pay attention to the application of biogas fertilizer. The following five points:
Administered immediately after a bogey out of the pool. Strong reducing of biogas, the pools of anaerobic fermentation residues administered immediately after, the soil it will compete with crops for oxygen, seed germination and root development, leading to crop foliage yellowing, wilting. Therefore, after the biogas fertilizer is discharged from the pond, it is generally applied after storage for 5-7 days in the septic tank; the biogas residue and the phosphate fertilizer are mixed in a ratio of 10:1 for 5-7 days, and the effect is better.
Second, avoid direct topdressing biogas manure is not watered. Applying directly to crops without water, especially for chasing seedlings, can cause crop burns. When the biogas fertilizer is used as top dressing, it must be watered first. Generally, the water is half of the biogas slurry.
Three bogey on the soil to spread the fertilizer. For crops applied to dry land, it is advisable to use acupoint application, ditch application, and then cover the soil; apply to the paddy field to spread the field evenly before the slab, and then plow into the bottom layer.
Four avoid excessive application. The amount of biogas fertilizer applied should not be too much, generally less than the application of ordinary pig manure. If blindly applied in large quantities, the crops will be long and the crops will be shaded, resulting in reduced production.
Five bogey is mixed with alkaline fertilizer such as grass ash and lime. Grass wood ash, lime and other alkaline are strong, mixed with biogas fertilizer, will cause loss of nitrogen fertilizer, reduce fertilizer efficiency.
