Fertilization mode

1, soil fertilization

Soil fertilization is the main way of artificial fertilization for trees. Organic fertilizer and most inorganic fertilizers (chemical fertilizers) use soil fertilization. Soil fertilization should be applied below the surface of human soil, which is beneficial to root absorption and can also reduce fertilizer loss.

4. Spraying fertilization method

Spread the fertilizer evenly around the trees, and then turn the fertilizer into the soil in late autumn, early winter or early spring with a subsoiling rake. It is suitable for adult trees whose roots have covered the whole garden, but it cannot be used for a long time.

5, fertilization outside the root

Comprises the following steps: spreading or spraying branches, injecting branches and spraying leaves. Foliar spraying is the most commonly used method in production.
