Orchard application of biological fertilizer attention

The application of biological bacterial fertilizer in the orchard can improve the utilization rate of fertilizer and reduce the investment cost; on the other hand, it can improve the soil aggregate structure, enhance the beneficial bacteria number and activity of soil microorganisms, improve the soil water storage capacity, and create good root growth for fruit trees. The environment makes the fruit trees grow stronger and the resistance is enhanced.

In the orchard fertilization, some fruit farmers will not rationally apply the biological fertilizer, and the effect is not obvious, and the confidence in using the fertilizer is lost. Two problems should be noticed in the application: First, in the ditch or acupoint to which the biological fertilizer is applied, it is strictly forbidden to directly irrigate the water and fertilizer such as unfertilized human and animal manure; try not to use the biological bacterial fertilizer and the quick-acting nitrogen fertilizer such as urea. And ammonium bicarbonate is mixed and applied to avoid killing the biological bacteria and reducing the fertilizer efficiency. The second is to use when the sensation is good and the temperature is suitable. When the temperature is lower than 5 °C, the biological fertilizer and the organic fertilizer and a large amount of elemental fertilizer compound fertilizer can exert the maximum efficiency.
