Background technique
Currently, carrying out nursery using the method for floating seedlings mainly in seedling raising greenhouse in cured tobacco production nursery field.
Floating seedling cultivation of fire-cured tobacco is to float on the foam hole tray (drift disk) equipped with Friendly tobacco seedling raising medium on the water surface, and seed is sowed in matrix,
Tobacco seedlings take root growth in seedling medium, and the method for culturing seedlings of moisture and nutrient can be absorbed from matrix and water bed.
Tobacco seed, which is sprouted, must have sufficient moisture, preference temperature and enough oxygen.Moisture is that seed is sprouted
First factor, temperature are that seed sprouts required second factor.Currently, floating seedling cultivation of fire-cured tobacco technology can satisfy nursery substantially
Demand to moisture, but the temperature source of floating seedlings relies primarily on sunlight at present, passes through the insulation effect of seedling raising greenhouse
Storage temperature.
However, chilling injury is a kind of noninfectious disease on tobacco leaf production.In tobacco in seedling stage, transplanting early stage and crop field
Later growth has the generation for damaging to plants caused by sudden drop in temperature phenomenon, especially with seedling by relatively conventional the phenomenon that damaging to plants caused by sudden drop in temperature.Seedling, can after by injury from low temperature
Inhibit the growth and development of cigarette strain, shortens vegetative growth phase, lead to early blossoming.Different degrees of microthermal climate is encountered in nursery stage, it is right
Emergence and tobacco seedling growth can have an adverse effect, and the low temperature that nursery initial stage occurs causes to be difficult to emerge, even if the tobacco seedlings gone out
Also due to cryogenic freezing is aggrieved.Low temperature is the factor being affected to nursery, young shoot wear break in the seed coat before must have it is higher
Temperature could germinate rapidly.Low temperature has larger impact, but influence of the low temperature degree difference to seedling growth and development to tobacco seedling growth
Degree is variant.In addition, data is shown, when larval rearing water temperature is at 18 DEG C or so, tobacco seedling growth is normal, when pond water temperature exists
At 13 DEG C or so, tobacco seedlings uniformity is reduced, if tobacco seedling growth will be by serious when pond water temperature is in 10 DEG C or less for a long time
It influences, symptoms, the too low temperature such as Lao Miao, the seedling that ossifys, root system jaundice, seedling leaves deformity, jaundice easily occur may cause children
Seedling is dead.
