Description
Technical Field
The invention relates to the field of tobacco seedling culture, in particular to a tobacco seeding and seedling culture method.
Background
Tobacco, annual or limited perennial herbs, solanaceae. The plant is glandular hair, the petiole is not obvious or becomes a wing-shaped petiole, the seed is round or wide and rectangular, and is tawny; native to south america, there is cultivation around the world. Tobacco is a raw material of the tobacco industry; the high and low output of the tobacco is directly related to the prosperity of the tobacco industry, and the decisive factor of the high and low output of the tobacco is the tobacco seedling culture; the seedling raising and sowing are related to not only whether the quantity of tobacco seedlings is sufficient, but also the thinning workload.
The existing tobacco mainly adopts flow line seeding and foam tray floating seedling. When the tobacco seedlings cultured in this way are transplanted to a field, a longer time for turning green is needed due to the change of the root environment. In addition, before the tobacco seedlings are transplanted, the tobacco seedlings are generally fertilized in the holes, and the seedlings are transplanted, so that the root system is easy to directly contact with the fertilizer, and the risk of burning the seedlings is caused. Therefore, two-stage seedling raising method is popularized in many tobacco areas in recent years, namely seeding is firstly carried out on a floating tray, seedlings are raised, then the seedlings are transferred to a pot tray to be cultured for a period of time and then transplanted to a field; therefore, the green returning of the transplanted tobacco seedlings is fast, and the tobacco seedlings are not harmful to fertilizer, and have the defect of time and labor waste.
