Mesh-bag-transplanted seedling breeding method for maritime pine seedlings

Abstract

The invention relates to a mesh-bag-transplanted seedling breeding method for maritime pine seedlings, which comprises the steps that (1) soil of a seedling breeding region selected for use is disinfected; (2) following air and water permeable mesh bags are selected as seedling breeding containers, wherein the mesh bag comprises a mesh bag body and a mesh bag bottom connected with the mesh bag body, and the areas of meshes on the mesh bag body and the mesh bag bottom are 0.25 to 1 square centimeters; (3) the seedlings are lifted; (4) the seedlings are bagged; (5) the seedlings are colonized; and (6) the seedlings are managed. The method has the advantages that through using the mesh bags woven by nylon and provided with the meshes of appropriate sizes as the transplanting containers, the maritime pine seedlings throughout grow in the mesh bags in the processes from seedling breeding to transplantation and afforestation, processes of transfer and packing are avoided, working procedures of the afforestation are reduced, the efficiency is improved, the seedling transplanting survival rate is increased, and the process of the afforestation becomes simpler, and is more convenient and easier to realize.

Description

technical field [0001] The invention relates to a method for transplanting and cultivating seedlings, in particular to a method for transplanting and cultivating coastal pine seedlings in mesh bags. Background technique [0002] At present, with people's attention to the environment and the improvement of greening requirements, the transplantation of seedlings has become very common, and the transplantation of coastal pine seedlings is particularly common. However, the following problems still exist in the process of transplanting coastal pine seedlings: [0003] First, the traditional method of transplanting pine plant seedlings is simply to dig out the seedlings from the seedling field, leave soil on the root system, wrap them up with a rope and then transport them to the planting site. This method is easy to damage the roots of the seedlings. After causing the seedlings to be transplanted, the survival rate is low or even the transplanting is unsuccessful. [0004] Secon...

AI Technical Summary

Problems solved by technology

[0004] Second, in the traditional pine plant seedling transplanting method, during the transportation process, due to the different specifications of the seedling root soil, the arrangement is not neat, and it is easy to be squeezed, so that the stems, leaves and roots of the seedlings are damaged, resulting in a low survival rate of the seedlings after transplantation. due to unsuccessful transplantation

[0005] Third, there are a variety of mesh bags on the market, because they are not professionally used for transplanting coastal pine seedlings. The design volume of the mesh bags is relatively small and the gaps are relatively small, so the roots of relatively large seedlings cannot pass through the mesh. The gaps in the bag will affect the root development of the coastal pine seedlings, which will easily cause the roots of the coastal pine seedlings to agglomerate, thereby affecting the development of the seedlings, so that the survival rate of the seedlings after transplantation is low or even the transplantation is unsuccessful.

[0006] As can be seen from the above, due to inadequate technical measures, it is easy to cause shortcomings such as unsuccessful transplantation of coastal pine seedlings or low survival rate after transplantation, thereby restricting the progress of afforestation or greening projects

In order to solve the problem of low survival rate in the process of transplanting Maritime pine seedlings caused by traditional methods and net bags in the market, it is necessary to improve the existing method for transplanting Maritime pine seedlings to increase the survival rate of transplantation
