Fertilization in orchards is one of the key measures to seize high yields, and it must be conducted 2-3 times a year. The fertilization of fruit trees is generally based on the method of excavation of annular grooves or radial grooves, which not only takes more time, but also causes greater damage to the roots of fruit trees. The “drilling†fertilization method explored by Liu Yangjun, a professional householder of fruit trees in Kaijiang County, has proved through years of experiments that this method has less damage to tree roots, saves time and labor, is easy to use, and has a small loss of fertilizer, and can also be used in large quantities. It is more effective to accumulate rainwater, which is very beneficial to the drought and security of mountain orchards. The general drilling can be used for sustainable fertilization for two years. After the crown of the consequence tree is expanded in 3 years, it is drilled again.
The practice is: on the ground around the fruit tree, under the canopy dripping line, using artificial or well drilling rig, drill 4-5 holes (according to the size of the canopy) vertically and drill the hole with a diameter of 30 cm and a depth of 0.8-1 m. , deciduous, thatch, swine manure, crop straw, etc. are filled into the hole.
In order to prevent the soil from filling the hole during the rain, the stone can be used to cover the hole. Every time fertilizing, only the stones need to be removed to fertilize. It should be noted that drilling is best done during the dormant period of fruit trees. If topdressing chemical fertilizers, apply 10 cm thick garden soil after fertilization to prevent fertilizers from evaporating.
