According to the modern nursery concept, good seedling containers and substrates are the key factors for cultivating seedlings. Seedlings that are difficult to penetrate such as plastic bags and hard plastic pipes are used as a container, and clay is used as a substrate to raise seedlings. The seedlings in the seedlings are bound to have abnormal root development. The abnormal root system of the seedlings will lead to the anchorage of the trees, the small space for absorbing water and nutrients, resulting in slow growth and poor resistance. The overall consequence is that the old man tree is caused. If the container is not properly selected, the consequence may be that the afforestation fails. Nowadays, monomers, easily penetrated, easily decomposed, and not recycled have become the mainstream of nursery containers.
Why is the survival rate of light-weight non-woven fabric container seedlings high, and the growth of trees is obviously better than that of plastic container seedlings? He said that the light-matrix non-woven container seedlings have no rooting phenomenon, and they also form a strange effect: once the seedlings are in the soil, they will grow directly, avoiding the seedling stage. If the seedlings have callus formed by air cutting, then After entering the soil, there will be explosive rooting, and the aerial part will be directly long. This is not possible with other types of containers so far. These expose the outer wall of the container and form the root segment of the callus, and the interior continuously supplies nutrients, forming a physiological state ready to be released. In the new concept of seedlings, this root callus is more advantageous than the formation of complex roots.
