Description

A Greenhouse Saving Seedling System

technical field

The invention relates to the technical field of horticultural cultivation, in particular to a greenhouse-saving seedling raising system.

Background technique

At present, my country is still in a relatively backward state in the application of seedling breeding technology. In the implementation of traditional seedling breeding technology, the growth cycle of seedlings and the corresponding quantity and quality can no longer meet the overall needs of the modern market.

In most cases, some traditional seedling raising techniques will use some containers with relatively small space to raise seedlings. Although this method can save a certain amount of space in the actual use process, the cultivated seedlings themselves are prone to root problems. In this way, in the process of cultivation and growth, the seedlings themselves will be seriously affected. First, the yield of the seedlings will be reduced. Thirdly, the overall quality of the seedlings cannot be effectively guaranteed.

Container seedling raising technology is one of the traditional seedling raising techniques. Container seedling raising technology mainly uses containers to effectively limit the roots of seedlings, which can not only fundamentally improve the overall survival rate of seedlings, but also improve the overall afforestation work. efficiency. During the implementation of the container seedling technology, although it can protect the roots of the seedlings well, it ignores the root quality problems of the seedlings themselves, which will also affect the survival rate of afforestation. In the continuous development, it has become an inevitable development trend to improve the overall quality and level of nursery stock.

At present, the most advanced seedling container technology is non-woven container technology. This technology can effectively adjust the diameter of the container and effectively control the height of the container, which can meet the needs of different types of seedlings during the cultivation process. However, when this method is used to raise seedlings, the root system of the seedlings is easy to penetrate into the lower soil, resulting in very long main roots, few lateral roots and fibrous roots, easy to cause plant damage when transplanting, and low utilization rate of fertilizer and water. Labor and water and fertilizer are wasted.

Therefore, how to provide a seedling cultivation device with high seedling cultivation quality is a technical problem to be solved urgently by those skilled in the art.
