First, the depth is shallow: most of the hairy roots of the fruit trees grow in the soil about 20-30cm, do not apply too deep when fertilizing, too deep fertilizer infiltration loss, reduce fertilizer efficiency, the depth of fertilization is about 30cm Improve the utilization rate of fertilizers.
Second, the pile is diversified: When fertilizing, it can be used to make annular fertilization, radiation ditch or oblique application, fertilizer should be dispersed, do not concentrate, if the fertilization is too concentrated, burn root hair. Weak tree potential, scattered fertilization mainly increases the absorption rate of roots and improves the utilization rate of fertilizer.
Third, the near is far: As we all know, after the fruit trees have expired, a large number of hairy roots are distributed on the outer edge of the canopy projection. When fertilizing, it is necessary to stay away from the middle pole 1 meter away. To call the roots to find fat, do not fatten the roots.
4. Rejuvenation is familiar: in the grassroots service, most members are found. The farmer directly applies the farmer's fertilizer that has not been matured to the orchard. This raw fertilizer has a ripening process in the soil and produces a large amount of heat. And the harmful gas brakes the root hairs of the hairy roots, so the more the raw fertilizer is applied, the weaker the tree. When using farmyard manure, it can be used after it has been matured.
V. Remixing into a single: When using farmyard manure, many members and fruit farmers mix the grass and ash together and apply them to the orchard. The acid-base reaction reduces the fertilizer efficiency. It is extremely unscientific. Therefore, the plant ash can only be applied alone, but not mixed. .
Sixth, the change of inorganic fertilizer to organic biological fertilizer: In recent years, fruit farmers use inorganic fertilizer in large quantities, the soil aggregate structure is destroyed, and the utilization rate of fertilizer is particularly low. Therefore, the preferred three-dimensional organic and inorganic biological bacterial fertilizer, this fertilizer is comprehensive in nutrition, can play a role in improving the soil and improving fertilizer efficiency.
