Description

A kind of scissors that improves the cutting efficiency of plant cuttings

technical field

The utility model relates to the field of plant cuttings, in particular to a pair of scissors for improving the pruning efficiency of plant cuttings.

Background technique

Seedlings are an important part of the planting industry, so efficient seedling breeding technology is an important basis for ensuring the current agricultural development. At present, the more common seedling propagation techniques include seed propagation, cutting seedling cultivation, tissue culture, division propagation, etc. Relatively speaking, cutting seedling cultivation is a method of seedling cultivation with simple operation, low cost and high reproduction efficiency, especially in forestry. , fruit trees, flowers and other fields are most widely used.

The initial step of cutting seedlings is the selection and treatment of cuttings, which is generally completed by scissors, including cutting branches from the female parent, segmenting branches, trimming incisions and leaves, etc. The overall steps are many and waste time, which greatly affects the process of seedling cultivation efficiency. In general, in order to improve the survival rate and rooting quality of seedlings, the branches are often cut into cuttings with a flat mouth at the top and a beveled mouth at the bottom; then the leaves at the lower 1/2-2/3 of the branches are cut off to form the final cuttings. Usually, for longer internodes, that is, when the number of leaves in the lower 1/2-2/3 is small, it is generally completed by cutting off one by one, while for shorter internodes, that is, the lower 1/2-2/3 When the number of leaves in the 3 places is large and dense, generally place the scissors in a position relatively parallel to the cuttings, and cut close to the cuticle epidermis, and cut off the leaves at the lower 1/2-2/3 of the cuttings in this direction each time, and then rotate Use the above method to cut the cuttings in the other direction. Therefore, in the process of leaf pruning, each cutting needs to be cut at least 3 times to complete the removal of all the leaves in the lower 1/2-2/3. At present, the scissors used for cutting seedlings in the market are ordinary scissors or branch shears. Each operation can only complete one cutting step, and there is no special scissors for improving work efficiency. As the level of science and technology continues to improve, the degree of agricultural mechanization is also increasing. As far as cutting seedlings are concerned, steps such as disinfection, soil preparation, and cuttings can be gradually completed by machinery, and work efficiency is also improving. Higher and more delicate, it cannot be replaced by machinery in a short period of time, and still needs to be completed by manual operation. Therefore, it is urgent to find tools and usage methods that can improve work efficiency.

The information disclosed in this background section is only intended to increase the understanding of the general background of the present invention, and should not be considered as an acknowledgment or in any form to imply that the information constitutes the prior art already known to those skilled in the art.
