High-efficiency tobacco seedling cultivation method

Abstract

The invention discloses a high-efficiency tobacco seedling cultivation method. The method includes the steps of accurately sowing seeds, applying fertilizer by stages, drawing in a sunshade net during the large-cross period of tobacco to receive sunlight illumination, opening a side film of a greenhouse during a seedling hardening period, spraying rare earth nutrient solution during the large-cross period to ensure nutrient required by tobacco seedlings, keeping timely ventilation to replenish the greenhouse with carbon dioxide so as to meet the requirement of photosynthesis when it is sunny, cutting leaves when the leaves of the tobacco seedlings overlap and are shaded, monitoring sanitary conditions constantly, cleaning and disinfecting the greenhouse and spraying insecticide every half a month, filling a floating disk with basic media, sowing the seeds in holes of the floating disk filled with the basic media, allowing the floating disk to float in a nutrition pool of the greenhouse, applying the fertilizer into water in the nutrition pool, carrying out management on the seedling cultivation process, hardening the seedlings before transplantation and finally directly transplanting the seedlings to a field after the seedlings are hardened. The high-efficiency tobacco seedling cultivation method has the advantages of improving the emergence uniformity of the seedlings, enhancing the root vitality of the tobacco seedlings, promoting the growth and development of the tobacco seedlings, improving the quality of the tobacco seedlings, being beneficial for cultivating the disease-free and strong tobacco seedlings and low in production cost, and improving the strong seedling rate.

Description

technical field [0001] The invention belongs to the technical field of tobacco seedling cultivation, and in particular relates to a method for cultivating tobacco seedlings with high efficiency. Background technique [0002] Tobacco is an important economic crop. The output value per mu and the commodity rate of tobacco are higher than other food crops, so it is deeply loved by tobacco growers, and the planting area is expanding year by year. Cultivating strong seedlings is the prerequisite for high yield of tobacco. The quality of tobacco cultivation is related to the satisfaction among cigarette industrial enterprises, commercial enterprises and consumers. At present, there are many deficiencies in tobacco cultivation, such as high cost, serious waste of resources, chaotic and disordered seedlings at the right age, strong The seedling rate is low. [0003] The traditional method for cultivating strong tobacco seedlings has the problems of messy and irregular tobacco seed...
