Description

fruit tree support

technical field

The utility model relates to the technical field of agricultural tools, in particular to a fruit tree supporting device.

Background technique

In the past, growers used bamboo poles to support fruit trees, with four columns and cross-arm support, which had the following disadvantages:

1. The use of a large number of bamboo poles will cause environmental damage and indiscriminate logging. The bamboo pole supports have a service life of up to 3 years, and the service life is short, which increases the demand, and the environmental damage will become more and more serious.

2. Bamboo poles are easy to crack and bear limited load. Once broken, it will cause great damage to fruit trees;

3. Bamboo poles are disassembled every year, which consumes a lot of manpower and material resources;

4. The four-column support method supported by bamboo poles is extremely inconvenient for weeding and fertilizing, and it is easy to be cut off by the lawn mower during weeding, which increases the amount of labor and materials;

5. The four-column support method supported by bamboo poles will expose the head of the bamboo poles, which poses a great safety hazard to the planters during the operation, and it is easy to stab the eyes, temples and other important parts.

6. When the fruit trees are irrigated, the ground becomes soft, and the bamboo poles will sag and cause the support to tilt, which will affect the support effect.
