Description

Technical field:

[0001] The invention discloses an orchard organic fertilizer inter-plant spreading machine, belongs to the field of agricultural machinery, and particularly relates to an orchard organic fertilizer application mechanical equipment. Background technology:

[0002] In recent years, the production of green organic food has become a trend. Green fruits can greatly increase the added value. People pay more attention to health and prefer green, safe and pollution-free healthy food. The requirements for the quality of crops are getting higher and higher. The market for organic fertilizers will become larger and larger, and the demand will also increase. The application of organic fertilizers in orchards is in line with the concept of green development, and the construction of organic orchards is also a general trend. The organic fertilizers used in agriculture mainly include compost, manure, straw, fungus residue, green manure and mud fertilizer. If these wastes are not effectively utilized, they will cause great pollution to the environment. However, applying them as organic fertilizers to the fields can not only improve soil structure, increase soil fertility, and increase the output rate of cultivated land, but also reduce the pollution caused by various wastes such as livestock and poultry manure, crop straw, and organic waste from production and life. It is an effective way to achieve sustainable agricultural development.

[0003] In production, the method of applying organic fertilizer is to first dig trenches on both sides of the fruit trees, and then fill the organic fertilizer into the trenches manually and cover them with soil. Manual fertilization is inefficient, labor-intensive, and costly, which binds a large number of laborers, and results in poor fertilization uniformity and low fertilizer utilization rate. With the continuous expansion of orchard planting areas and the continuous improvement of modern planting management techniques, people have higher and higher requirements for mechanized application of organic fertilizers to fruit trees, while my country's orchard fertilization machinery is still imperfect, especially because the mechanical technology for fertilizing the crowns and between plants in orchards is relatively difficult, and the mechanized fertilization in orchards is relatively limited, which is far from meeting the orchard's technical requirements for fertilization machinery. In addition, in terms of machinery for ordinary field fertilization, my country still lacks machinery that can adaptively control fertilization areas and fertilizer amounts of different standards, which requires fertilization machinery to have a certain degree of adaptability and controllability to fertilization techniques of different field standards.

[0004] The invention discloses an orchard organic fertilizer inter-row spreading machine. The device can not only realize the mechanized application of organic fertilizer between the orchard plants and solve the technical difficulty of inter-row fertilization in the orchard, but also can carry out mechanized fertilization with adjustable fertilization area and fertilizer amount on ordinary fields of different standards. The device has the characteristics of high fertilization efficiency, strong adaptability, economy and practicality. The device is suitable for spreading fertilizer in the inter-row area of ​​the orchard or under the crown of the fruit tree to form strips, is particularly suitable for applying solid organic fertilizer in the ditch of the orchard, and is also suitable for large-area fertilizer spreading operations in ordinary crop fields with adjustable fertilizer spreading range. Summary of the invention:
