Annular groove digging-chiseling machine for fertilizing fruit trees and fertilizing method for fruit trees

Abstract

The invention relates to an annular groove digging-chiseling machine for fertilizing fruit trees and a fertilizing method for the fruit trees. The annular groove digging-chiseling machine comprises a tree clamping device, a rack, a digging-chiseling mechanism and a locking screw, wherein a positioning rod extending outwardly in the radial direction of the tree clamping device is arranged outside the tree clamping device; the digging-chiseling mechanism is mounted on the rack; the rack is provided with a through hole; the inner wall of the through hole is provided with a threaded hole; the rack is arranged on the positioning rod through the through hole in a sleeving manner; and the locking screw is screwed in the threaded hole and is connected with the positioning rod. The fertilizing method for the fruit trees comprises the following steps: digging-chiseling annular fertilizing ditches by using an annular groove digging-chiseling machine and then performing quantitative fertilization. By adopting the technical scheme provided by the invention, mechanized equipment can replace manual operation to form the fertilizing ditches, so that the manual labor burden of farmers is reduced and the efficiency of fertilizing by the formers is improved; the digging positions of the fertilizing ditches are accurate, thereby facilitating absorption of the fruit trees on nutrients, promoting growth and development of the fruit trees and improving the fertilizing efficiency in an orchard.

Description

technical field [0001] The invention belongs to the technical field of fruit tree planting, and in particular relates to an annular trench planer and a method for fertilizing fruit trees. Background technique [0002] Fruit trees are perennial plants. After they are planted, they will grow in one place for decades. A large number of branches and fruits will grow every year, which consumes a lot of nutrients in the soil. Production practice has proved that timely application of necessary nutrients to fruit trees is an important measure to improve fruit tree yield and fruit quality; fruit tree fertilization methods mainly include hole fertilization, radial furrow fertilization, ring furrow fertilization, strip furrow fertilization, etc. Among them, the ring-shaped ditch fertilization method is the most widely used. It refers to the fertilization method that takes the tree trunk as the center, excavates a ring-shaped ditch at the outer edge of the vertical projection of the tre...

Production practice has proved that timely application of necessary nutrients to fruit trees is an important measure to improve fruit tree yield and fruit quality; fruit tree fertilization methods mainly include hole fertilization, radial furrow fertilization, ring furrow fertilization, strip furrow fertilization, etc. Among them, the ring-shaped ditch fertilization method is the most widely used. It refers to the fertilization method that takes the tree trunk as the center, excavates a ring-shaped ditch at the outer edge of the vertical projection of the tree crown, and then mixes the fertilizer with the fertilizer suddenly and fills it into the ditch. The fertilization method is especially suitable for use when applying base fertilizer to fruit trees in autumn; for example, the patent document with the publication number "CN103931463A" discloses an integrated fertilization method for fruit trees using waste fungus residues, using decomposed waste fungus residues to fertilize nitrogen Phosphorus and potassium fertilizers are used as base fertilizer for fruit trees. When topdressing fruit trees with nitrogen, phosphorus and potassium fertilizers, use the extract of bacteria residues to apply medium and trace element fertilizers for foliar topdressing, and / or use the extracts of bacteria residues to flush with water during irrigation. The function of topdressing is to spray the extract of fungus residue on the leaves and trunks of fruit trees to improve the stress resistance of crops and reduce the occurrence of diseases. Using the technical scheme of this invention, the process of fertilization is still manual operation, which has low labor efficiency and increases The burden of farmers is unfavorable for large-scale production. Another example is the patent document whose publication number is "CN103858564A", which discloses a fruit tree planer hole and fertilization integrated machine, including a frame, a planer hole mechanism and a fertilization mechanism; The hole mechanism is arranged in the middle part of the frame; the planer hole mechanism includes a driving device, a reduction box, and an auger; the auger is connected with the output shaft of the reduction box at the lower end of the driving device, and the lower end of the auger is equipped with The two detachable blades are fixedly connected by bolts; the driving device and the reduction box are fixed on the base of the frame; , the fertilizing mechanism is located at the front side of the planing hole mechanism; the fertilizing mechanism includes a fertilizer box, a fertilizer quantitative control device and a material guide groove; the fertilizer box is arranged on a frame, and the bottom of the fertilizer box is in contact with the The fertilizer quantitative control device is connected through the tie bars, and the lower outlet of the guide groove is set toward the drill bit. Using the technical solution of the invention, although the mechanization level of the fertilization operation is increased to some extent, the invention reuses the At the same time, because the planing hole mechanism has not achieved complete positioning, the fertilization position is very random. Generally speaking, since the rhizome of the fruit tree is diverged from the trunk, as the age of the fruit tree increases, the rhizome of the fruit tree is also longer. The end of the rhizome is the place with the strongest ability to absorb nutrients. Therefore, when the fertilization position is too random, it often makes the fruit tree unable to fully absorb enough nutrients, which affects the growth of the fruit tree and the yield of the fruit.
