Plug seedlings. It is a method of raising seedlings using plastic plugs as containers. The seedling plate is divided into cells, one cell and one strain. When the seedlings grow, the root system and the matrix are intertwined with each other, and the roots and soils are in the shape of a small plug at the big end. Using this new method, it has the advantages of energy saving, labor saving, labor saving, saving soil and seedbed area, saving the use of species, facilitating long-distance transportation, and facilitating the use of standardized nursery management techniques, etc. It is easy to plant and survive, no seedlings, seedling quality. Good, strong growth, high output. Electric hotline nursery. It is a seedling raising method that uses electric currents to pass electric wires to convert electric energy into heat and heat. It has the advantages of rapid and stable soil temperature rise and good temperature increase effect. It can effectively regulate the temperature of roots needed for different stages of seedling raising by means of a temperature control device. It is easy to manage, quick to emerge and neat, and prevents rotting. The shortening of seedling age promotes early maturing and high yield. Winter and spring nursery can be widely used. Grafting seedlings. The technique of grafting the bud or branch of the value object (scion) to an appropriate part of another plant body (rootstock) to join the two into a new plant body. Grafting techniques are used to cultivate seedlings called grafted seedlings. Grafting seedlings can effectively prevent soil-borne diseases such as blight caused by continuous cropping. Grafting seedlings also have the advantages of advanced root systems, strong growth potential, strong resistance to low temperature in the root system, prolonged growth period, and increased output value. At present, the technology is widely used, such as grafting cucumber with black-skin squash and grafting watermelon with squash as rootstock. The group raises seedlings. Under aseptic conditions, the isolated vegetable organ tissue cells or protoplasts are cultured on a medium to promote their division or induction of seedlings, a technique known as vegetable tissue culture. The method of using tissue culture technology to raise seedlings is tissue culture. It has the advantages of rapid propagation and mass production. In addition, there are other effects that can not be achieved by breeding methods, such as the cultivation of virus-free vaccines. Potato virus-free seedlings are cultivated by tissue culture. Soilless seedlings. Without using soil, the method of raising seedlings in a special container with a compounded inorganic nutrient solution is called soilless seedling raising. Soilless seedlings facilitate scientific and systematic management. Breeding seedlings also facilitate long-distance transportation. China Agricultural Network Editor
