How to improve the efficiency of bio-fertilizers. In recent years, bio-fertilizers have received extensive attention. Generally, bio-fertilizers can be used as base fertilizers, top dressings, ditching or acupoints, and can also be used for seed dressing, soaking seeds, roots or leaves. Spraying on the surface, depending on the type of fertilizer. The agricultural fungus type is mixed with 2 kg of solid bacteria and 40-60 kg of decomposed organic fertilizer per mu, and then used as base fertilizer, top dressing or seedling.
The solid bacteria agent and the nutrient soil are mixed to prepare nutrient mash, or mixed with the mud slurry, and the roots are rooted before the seedlings are transplanted; the seeds are immersed in the 10-20 times bacterial agent dilution solution or sprayed with the diluent before sowing. The seed is fully contacted with the liquid biological agent and then sown; before the seedling is transplanted, the root is immersed in a liquid microbial agent diluted 10-20 times, and then immediately taken out, or the root of the seedling is sprayed with the above dilution; the microbial agent is diluted 100 After the double is used for rooting or flushing; the fungicide is diluted 500 times for foliar fertilizer.
The compound microbial fertilizer can be used as base fertilizer and top dressing, and the application amount per acre is 10-20 kg; the fertilizer is diluted 500 times for foliar fertilizer, and sprayed according to the requirements of the product specification. Bio-organic fertilizer can be used as base fertilizer and top dressing. When applying base fertilizer, the application amount per acre is about 100 kg. It is best to apply appropriate amount of farmyard manure; the amount of topdressing fertilizer is appropriately reduced, and it is applied 7 to 10 days earlier than chemical fertilizer, and it should be applied with appropriate fertilizer. .
In addition, when the soil nitrogen, phosphorus, potassium nutrient content is high or a large amount of nitrogen, phosphorus, potassium fertilizer is applied, the effect of rhizobium, phosphate and potassium-dissolving fertilizer is reduced, and even inhibited. For example, excessive application of nitrogen fertilizer inhibits nodule The activity of the bacteria reduces the nitrogen fixation of the nodule.
In addition, note that the beneficial microorganisms in the bacterial fertilizer are alive, so they should not be mixed with pesticides, chemical fertilizers and peracids or over-alkali substances during storage; do not mix with a large amount of chemical fertilizers or acid-alkaline fertilizers; Alkali becomes a drought and the effect of the fertilizer is played.
