Analysis of Environmental Factors of Tobacco Seed Germination

Tobacco seeds look small. The seeds of common tobacco (such as flue-cured tobacco, oriental tobacco, burley tobacco, etc.) are about 0.65 to 0.80 mm in length and 0.45 to 0.55 mm in width. Although the seeds of yellow tobacco are larger than the seeds of ordinary tobacco, its weight is only Three times the weight of common tobacco seeds. Compared with the large-grained seeds of some crops such as wheat, corn and soybeans, the body contains less nutrients.

Although the seeds of tobacco seeds are relatively small, the so-called sparrows are small and well-organized. Small seeds also need germination. Only germination has a certain degree of difficulty. The germination of tobacco seeds has a certain relationship with the morphology, dormancy, longevity and external environment of the seeds. Which with the temperature, moisture, light intensity, oxygen, the greatest impact. As for the seed's own factors, we can use the appropriate seed testing equipment to delete the seeds, there are seed hair dryer, seed cleanness table and so on. The external environmental factors can be obtained by giving different environmental parameters and then comparing them to obtain the final result. Among them, we can use small weather stations to determine some environmental factors, including temperature, humidity, illuminance, wind speed, and many other environmental parameters. The hand-held meteorological station obtains the corresponding data measurement by connecting a plurality of sensors. It is because of the hand-held weather stations that we can better measure the germination of tobacco seeds in a timely manner and make corresponding adjustments.
