Container seedling cultivation is the use of various containers loaded with cultivation substrate to cultivate seedlings, and the resulting seedlings are container seedlings.
Container seedlings began in the mid-fifties of the twentieth century.
Container seedlings have been widely used in the cultivation of vegetables, flowers, seedlings, ornamental plants, etc., and have become one of the important parts of intensive facility cultivation. At present, many garden nurseries have adopted container seedlings to varying degrees.
The first question is, what are the advantages of container seedlings?
Advantage 1: Make full use of limited seed resources. Especially for genetically improved seeds or rare tree species, due to the limited number of seeds, the use of container seedlings can obtain a higher emergence rate.
Advantage 2: It can improve the survival rate of seedlings transplanted. The container seedlings are transplanted with whole roots and seedlings, and the root system has not been damaged in any way, so the survival rate of transplantation can reach almost 100%.
Employment. Advantage three, container seedlings are not limited by the transplanting season, can extend the transplantation time, and can be transplanted at any time, which is conducive to reasonable arrangement.
Advantage four, container seedlings because of the container, can not occupy a good land when cultivating.
Advantage five, there is no slow seedling period after container seedling transplantation, and the growth is fast
Advantage six, the seedlings cultivated by container seedlings are uniform and neat, suitable for mechanized operation, and effectively improve labor productivity.
Of course, container seedlings also have disadvantages, such as lower seedling yields and higher costs.
The second question is, what are the types of seedling containers?
Seedling containers vary with the change of materials, size, and shape, and are constantly improving. According to the shape, the seedling container can be divided into: simple (tube-shaped), conical (bullet-shaped), square, hexagonal, book-shaped, honeycomb-shaped, nutritional brick and other types.
According to the production materials, seedling containers can be divided into: paper, clay, synthetic fiber, soft and hard plastics, biodegradable plastics, peat, polyethylene foam and other types.
According to the planting method, seedling containers can be divided into two categories: planting containers and non-planting (can be **) containers. Plantable containers are usually paper cups, clay nutrient cups, peat containers, nutrient bricks, nutrient cups, etc. Non-planting containers are generally made of plastic, polyethylene and other materials.
There are several longitudinal prismatic protrusions standing inside the container, and the seedling roots stretch down along the ridge line to prevent the root system from circling in the container.
The third question is, how to configure the soil material of the seedling substrate?
The materials commonly used to prepare the substrate are: peat, vermiculite, perlite, bark powder, understory soil of woods, uncultivated mountain soil, etc., which have the characteristics of loose and breathable, strong water holding capacity and light texture.
