A soil ball bag for covering soil balls in seedling transportation

Abstract

The invention discloses a soil ball bag for covering soil balls in the transportation of seedlings. The part is a long, axially symmetrical figure with narrower ends and the widest middle and upper part. The number of fixed parts and extended parts is at least two. The lower edge of the extension part is sewn on the outer edge of the film part; the upper edge of the fixed part and the extension part is closed and then inserted into the closing rope; the skeleton is composed of a circle and a warp skeleton, the diameter of the circle is slightly smaller than the diameter of the film part, and it is connected with the film part Concentric and sewn on the bottom part, the warp skeleton is sewn on the fixed part along the symmetrical axis of the fixed part, and the lower end of the warp skeleton is provided with a round hole and is flexibly connected to the circle; the tooth chain belt of the zipper is sewn on the fixed part and the extension part Patchwork. The present invention can be used repeatedly, is very convenient to put on and take off, and can be applied to soil balls of various sizes, which is worth popularizing.

Description

technical field [0001] The invention relates to the technical field of a soil ball covering device during seedling transportation, in particular to a soil ball bag for covering soil balls during seedling transportation. Background technique [0002] When the seedlings are transplanted, in order to ensure the survival rate after transplantation, when the seedlings are excavated, the soil around the roots of the seedlings and within a certain depth range are dug out together with the roots of the seedlings to form soil balls. When excavating, the specific size of the soil ball needs to be considered according to the characteristics of the tree species, size, tree age, soil conditions, and economic conditions. Generally speaking, the diameter of the soil ball is 7-10 times the DBH of the tree, and the height of the soil ball depends on the tree species, and generally does not exceed the diameter of the soil ball. For artificially planted large trees, because there are almost n...

Problems solved by technology

In order to prevent the soil balls from loosening during transportation, straw ropes are generally used to bind the soil balls. According to the size of the soil balls, the strength and density of the binding are determined. Straw ropes are divided into single-strand biaxial, double-strand biaxial, etc. Regardless of the binding method, the binding effect can affect the survival rate of the final transplant. Therefore, the technical requirements for binding are high, and the binding process is time-consuming and labor-intensive. When planting, it is necessary to remove the grass rope on the soil ball, which is another time-consuming process. Time-consuming and labor-intensive process, and the removed straw rope cannot be reused, so improvement is urgently needed
