The invention discloses a
plant pulling and under-membrane
transplanting method for floating tobacco
seedling raising, and relates to the technical field of tobacco planting. The method comprises the following steps: performing field building, preparing
seedling raising plates and
seedling raising substrates, loading the substrates to the plates and performing
sowing, and performing management in a seedling stage to obtain strong seedlings;
transplanting the strong seedlings in the seedling raising plates to tobacco ridges in time and in batches through an under-membrane
transplanting method; and continuing to cultivate remained weak seedlings for 3-5 days, wherein the strong seedlings are tobacco seedlings which have a stem height of 6-10cm and a stem girth of 1-2cm, have 4-5 functional leaves, are subjected to leaf shearing for 1-2 times, are hardened for not less than 10 days, and have a seedling age of 60-70 days. According to the invention, the method for
flue-cured tobacco seedling raising has the advantages of intensification, management normalization, tobacco seedling growth accordance, less diseases and
insect pests, a short tobacco seedling restitution stage, robust tobacco seedlings, simple and convenient transplanting and the like; and tobacco seedling
utilization rate through the under-membrane transplanting method is improved, the seedling restitution stage is effectively shortened, tobacco
plant survival is facilitated, and
flue-cured tobacco
economic benefits are increased.
