How to use microbial fertilizer rationally
Can be used as basal fertilizer, top dressing, can be applied to the ditch or hole, can also be used for seed dressing, soaking, rooting or foliar spray, depending on the type of bacteria fertilizer.
The agricultural bacterial agent mu is mixed with 2 kg of solid microbial inoculum and 40-60 kg of decomposed organic fertilizer to be used as base fertilizer, top dressing or nursery seedling. The solid microbial preparation and nutrient soil are mixed to make nutrient earthworms, or mixed with dilute mud. Before sowing, roots are sowed; before sowing, seeds are immersed in 10-20-fold dilutions of the bacterial agents or sprayed with diluents to allow the seeds to fully contact the liquid biological agents before sowing; the seedlings are immersed in the roots to dilute 10-20 before transplanting. In the liquid bacterial inoculum, remove immediately, or spray the roots of the seedlings with the above dilution solution; dilute the bacteria to 100 times and then use it for root irrigation or flushing; dilute the bacteria to 500 times as foliar fertilizer.
The compound microbial fertilizer can be used as base fertilizer and top dressing, and the application amount of mu is 10-20 kg; it is diluted 500 times as foliar fertilizer and sprayed according to the product specification.
Bio-organic fertilizer can be used as basal fertilizer and top dressing. When basal fertilizer is used, the application amount of mu is about 100 kg. It is best to apply proper amount of farmyard fertilizer; the amount of topdressing fertilizer is appropriately reduced and applied in 7-10 days in advance of chemical fertilizer, and suitable amount of quantified fertilizer should be applied.
In addition, when the soil N, P, K nutrient content is high or when a large amount of nitrogen, phosphorus and potassium fertilizers are applied, the effects of rhizobia, phosphate-solubilizing bacteria, and potassium-releasing bacteria fertilizers are reduced or even inhibited. For example, excessive application of nitrogen fertilizer can inhibit the activity of rhizobia. , to reduce root nodules nitrogen fixation. Also note that the beneficial microorganisms in the fungus fertilizer are alive, so they must not be mixed with pesticides, fertilizers, and peracids and overbased substances during storage, and should not be mixed with large amounts of chemical fertilizers or acid-alkaline fertilizers. Alkali or drought affects the exertion of bacterial fertilizer.
