Embodiment Construction

[0013] The present invention will be further described in detail below in conjunction with specific embodiments and experiments.

[0014] During specific implementation, this method is that the straw coal matrix made from flue-cured tobacco straw is used instead of the traditional matrix to fill in the holes of the seedling tray for seedling cultivation, and the seedlings are raised in moist conditions between the sowing and the growth of the tobacco seedlings to the big cross stage. To the seedling stage, the method of floating seedlings is adopted. Wherein, the straw coal matrix prepared from the flue-cured tobacco straw is specifically prepared by the following method: first, the flue-cured tobacco straw is used as a raw material, and carbonized for about 12 hours under the condition of isolating air and hypoxia, so that the straw biomass is decomposed , the straw coal that forms biomass carbon has a calorific value between 15956.60-17620.71 kJ / kg, an ash content of about 1...

Abstract

The invention discloses a cured tobacco seedling culturing method, which is characterized in that: straw coal substrates made of cured tobacco straws instead of the conventional substrate are filled into holes on a seed tray for seedling culturing; in a period lasting from sowing to the growth of tobacco seedlings to seedlings with 3-4 leaves, seedling culturing on moist trays is adopted; and seedling culturing in floating trays is adopted from the stage of 3-4 leaves to a seedling period. Compared with the prior art, the method has the advantages of low cost, good seedling culturing effect, shorter seedling culturing time and capability of recycling waste cured tobacco straws.

Description

technical field [0001] The invention relates to seedling raising technology, in particular to a flue-cured tobacco seedling raising method. Background technique [0002] Flue-cured tobacco is an annual herb belonging to the family Solanaceae. To improve the quality of flue-cured tobacco, the cultivation of flue-cured tobacco seedlings is a more important key. [0003] At present, in the field of flue-cured tobacco seedling cultivation, flue-cured tobacco floating seedling cultivation, wet seedling cultivation and sand cultivation technology are the main technical means of tobacco seedling cultivation in the country. Among them, the rapid development of these three seedling technologies benefits from the advancement and practicability of the technology itself. At the same time, certain limitations have also been exposed in practice. For example: the formula of conventional substrates is complex; the cost of conventional substrates is high; the ecological environment is dest...
