Benefits of matching chemical fertilizer with organic fertilizer
1. According to the experiment, the content of organic matter, ammonifying bacteria, aerobic nitrogen-fixing bacteria and cellulose decomposing bacteria increased by 0.08%-0.11%, 260%, 119% and 600% respectively in the land with chemical fertilizer combined with organic fertilizer for 3 years. two。 The combination of high-yield, high-quality chemical fertilizer and organic fertilizer in medium-and low-yield fields can increase the yield by 10% to 20% compared with the single application of chemical fertilizer, and the grain quality has also been greatly improved. 3. The experiment of reducing the loss of chemical fertilizer shows that the combination of chemical fertilizer and organic fertilizer can not only reduce the redox potential of soil, reduce the nitrification of ammonia, but also reduce the volatilization loss of nitrogen. Generally, the nitrogen use efficiency can be increased by 10% to 15%.

The application of organic fertilizer should be enough.
Compared with traditional composting, biological composting has the advantages of convenient retting, labor-saving, time-saving, low cost, high fertilizer efficiency and so on. The specific operation method is to use roadside, land and abandoned pits to add water, urea and bacteria to wheat and corn stalks in a certain proportion, and then seal them with soil or mud.

Fruit trees should pay attention to the application of organic fertilizer.
1. Organic fertilizers should be combined with chemical fertilizers. At present, more than 90% of organic fertilizers applied in orchards are farm manure. These fertilizers contain a large amount of nitrogen, phosphorus and potassium and a certain amount of medium elements (calcium, magnesium), trace elements (iron, boron, manganese, zinc, copper, etc.) and bioactive substances, which can not only provide comprehensive nutrition for fruit trees.
