Description

A kind of sandy land economic forest seedling cultivation device and cultivation method thereof

technical field

The invention relates to the technical field of sandy land greening, in particular to a sandy land economic forest seedling cultivation device and a cultivation method thereof.

Background technique

Land desertification refers to the phenomenon that due to soil erosion, the surface soil loses fine grains and gradually becomes sandy, or due to the invasion of quicksand, land productivity decreases or even loses. In order to protect the ecological environment and prevent soil desertification, poplar is usually planted in sandy areas. The tree is a tree with strong viability.

When planting poplar, it is usually divided into four steps of digging, backfilling, planting and covering soil, while in the prior art, when digging a pit, it is usually carried out with a manual hand-held shovel, which not only requires the use and consumes a lot of labor , and the digging efficiency is also low, so it is not suitable for large-scale planting.

Existing patent (notification number: CN214257120U) has proposed a kind of poplar planting digging device in sandy land, only need start hydraulic cylinder and motor, and the conical digging head rotates and moves downward under the drive of hydraulic cylinder and motor, That is, the digging operation on the ground is completed. This design enhances the automation of digging, reduces the labor loss of manual digging, and effectively improves the work efficiency of digging.

Yet above-mentioned poplar planting digging device in actual application:

1. It can only dig one planting pit in a single operation. In areas with large sandy areas, this method of digging pits is bound to be inefficient and waste a lot of time;

2. Before planting in sandy land, it is necessary to dig out the silt on the soil surface through the equipment until the soil is exposed before digging. Therefore, the partial exposure of the soil is realized after a certain amount of work. However, the excavated by the above-mentioned device The distance between planting pits depends on manual judgment. If the distance is too small, it will affect the normal growth of poplar trees, and if the distance is too large, precious soil resources will be wasted;

3. Digging pits in sand often encounter hard objects such as stones below the ground. The above-mentioned pit digging device cannot provide corresponding protection for the drill bit after encountering hard objects during the digging process, so the service life is relatively short. The number of drill bits required to complete the excavation work of a piece of sandy land is relatively large, which increases the cost.

For this reason, we propose a kind of sandy land economic forest seedling cultivation device and cultivation method thereof to solve the above problems.
