How to ferment rapeseed oil residue to make fertilizer? Green ecological agriculture practices
Rapeseed oil is rich in N, P and K elements, and is an excellent organic fertilizer. Now I'm going to teach you how to use vegetable oil residues to make fertilizer. 1. Preparation of raw materials 1. Rapeseed residue 2. Bacterial medium 3. Water. 4。membrane or airtight container.
Second, the production method 1. Put the rapeseed in a clean, dry and ventilated place and let it stand for a week, stir-frying continuously during the process to allow the rapeseed to fully ferment. 2.The vegetable oil residue and microbial strains are mixed according to the prescribed ratio, and under normal circumstances, the appropriate amount of strains is 100:1. 3.Add water, mix well, and maintain a humidity of 60%, which means you can pick up a piece but it won't fall off. 4.Put the mixture in an airtight package, such as a plastic bag or fermenter, and keep it tightly closed to prevent gas intrusion. 5.Fermentation takes place in a suitable environment, usually 1 month. During this process, the fermentation state should be observed from time to time, and if the water temperature is found to be too high or too low, it should be adjusted in time. 6.If there is a strong smell of ammonia in the fertilizer, it means that the fertilizer is fully mature. At this time, the fertilizer should be taken out and dried before it can be used.
3. Application method 1: Rapeseed residue fertilizer is organic fertilizer, which cannot replace chemical fertilizer and needs to be scientifically applied. 2.The dosage depends on the specific land conditions and plant needs, too much dosage can cause root burns or have an adverse effect on the normal growth of the plant. 3.When applying fertilizer, it is necessary to cover the soil well and do not come into direct contact with the root system of the plant, otherwise it will cause root burns. 4.Rapeseed residue fertilizer is suitable for the cultivation of vegetables, flowers and fruit trees, and has a good growth-promoting effect and improves crop yield.
4. Precautions 1. During the production period, it is necessary to try to prevent the production of mold, bacteria and other harmful substances, so as not to adversely affect the quality of production. 2.In the production process, it is necessary to pay attention to the adjustment of temperature and humidity, as high temperature will make the bacteria lose their vitality, and a large number of bacteria will be produced in a humid environment. 3.When applying vegetable oil residue fertilizer, it is necessary not to mix it with chemical fertilizer, otherwise it will affect the effect of fertilizer due to chemical action. 4.Rapeseed fertilizer belongs to the organic fertilizer category, because it is rich in organic matter and microorganisms, it should not be mixed with other chemical agents, so as not to cause the death of harmful bacteria.
