Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of agricultural production, and more particularly relates to a hole fertilization method and a cutter for fruit trees. BACKGROUND

[0002] Fertilization management of fruit trees plays an important role in the farming operation of orchards in hilly and mountainous areas, which is directly related to the survival life of fruit trees, the yield of orchards, the quality of fruits and the sales price. At present, the fertilization technology for fruit trees mainly includes soil base fertilization, pipe type water and fertilizer integration and atomization spraying.

[0003] As a traditional method, soil base fertilization can use both organic and inorganic fertilizers to improve soil structure, promote the growth of fruit trees and improve the quality of fruits. In comparison, pipe type water and fertilizer integration and atomization spraying mainly use inorganic fertilizers, which are easy to operate and efficient, but long-term use of inorganic fertilizers may lead to soil compaction, affecting the quality indicators such as sugar content and acidity of fruits. In addition, these two methods are easily affected by weather and have a high risk of fertilizer loss. Soil base fertilization can effectively improve the sugar content and overall quality of fruits, and the application process is less affected by environmental factors, with higher efficiency and higher utilization rate of fertilizer absorption by fruit trees. It can be seen that soil base fertilization is an excellent way of fertilization for fruit trees. However, in hilly and mountainous orchards, due to the limitations of terrain and planting methods, soil base fertilization still uses the "shallow pit and ladle irrigation" technology of manual operation, that is, a small ditching machine or excavator is used to dig holes, and then manual watering, fertilization and soil covering are carried out. The small ditching machine or excavator is large in size, and it is difficult to realize root fertilization of fruit trees. Moreover, the depth of the hole is shallow, so this method not only has low mechanization degree, high labor intensity and low efficiency, but also has unsatisfactory fertilization quality.

[0004] Therefore, it is necessary to propose a new hole fertilization scheme for fruit trees. SUMMARY

[0005] The present application is to overcome the problems of poor positioning hole fertilization accuracy, poor flexibility, low hole drilling efficiency and poor fertilization quality of the existing fruit tree fertilization methods.
