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. ?? His approach is: in the ground around the fruit tree, under the canopy drip line, using artificial or well drilling rig, drill down 4-5 (depending on the size of the crown) diameter of 30 cm, 0.8-1 meters deep hole Then, the branches, leaves, thatch, pig cow dung, crop straw, etc. are filled into the holes. To prevent the mud from filling the hole during rain, cover the hole with stones. Whenever fertilizing, just remove the stone and fertilize it. 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.
