The specific method of drilling is: under the drip line of the base canopy around the base of the fruit tree, drill the vertical drilling rig with 4-5 diameter holes of 30 cm and depth of 0.8-1.0 m, then the leaves and thatch , cattle pig pen dung, crop straw, etc. are filled into the hole. In order to prevent the mud from filling the hole when it rains, the hole can be covered with stones, and each time the fertilizer is applied, the stone can be fertilized only by removing the stone. The drilling time should be carried out during the winter dormancy period of the fruit trees. If you apply fertilizer, after applying fertilizer, cover 10 cm of soil on the hole to prevent loss of fat.

Fruit tree drilling and fertilization method
Conventional fruit tree fertilization uses fertilization methods for excavating annular grooves or radiation ditch. This method takes more time and damages the roots of fruit trees. In recent years, some fruit farmers have adopted methods of drilling and fertilizing around the base of fruit trees. It is convenient and flexible, saves labor, has less damage to fruit trees, and has less fat loss. It can also make full use of a large amount of human and animal excrement in rural areas, with low cost, good effect and reduced environmental pollution. In addition, drilling and fertilizing can accumulate rainwater, which is beneficial to the drought resistance of mountain orchards. Generally, the hole is drilled once for 2-3 years, and the tree crown of the consequence tree is enlarged and drilled separately.
