A kind of tobacco seedling method
Technical field
The present invention relates to botanical seedling culturing field, and in particular to a kind of tobacco seedling method.
Background technology
Modern installations origin of agriculture, in the 1950's, is the product of modern scientific theory and technology development.Modern times set
The basic theories for applying agricultural is the plant " theory of mineral nutrition " that 19 th Century German scientists propose.Lee J.von in 1842 is than uncommon
Make the report of entitled " Chemical activator is in agricultural and physiology " in AAAS.Hereafter the mineral theory of plant nutrient
Gradually received by people.About in 1851~1856 years, J.-B. Bu Senge with sandy culture study plant mineral nutrition, 1699
Year R.B. Woodward water cultures studied the nutrition of mint.J.von saxophones in 1860, W. Ke Nuopu in
1861 water culture techniques for having established modern age.An other basic technology of modern installations agricultural is American scientist in 1949
F.W.Went proposes the theory of manual simulation's ecological environment.From this, exploration and pursuit day of the people for modern installations agricultural
Tend to become strong strong.
Develop efficient modern installations agricultural for the importance and necessity of China is self-evident, without superfluous words.
But, China's modern installations are agriculture to start late, and the most widely used industry of China's modern installations agricultural is tobacco seedling, flower
Grass cultivating seedlings, growing vegetables, raising rice seedlings, corn nursery etc..The agricultural facilities such as booth, greenhouse, plant factor should be said
The contribution of the popularization and application agriculture stable development current to China it is critical that.
But some crucial technical bottlenecks are faced all the time during the utilization in decades of modern installations agricultural.For example, cigarette
Careless seedling raising greenhouse, the specification of tobacco seedling factory and corresponding configuration are horizontal highests in current facility agriculture field, including temperature
Degree regulations, humidity regulation, Illumination adjusting, nutrition adjustment, but therefore and tobacco seedling effect also do not allow tobacco planting family
It is satisfied.The existing tobacco booth of China (nursery factory) adopts floating seedlings mode, and its loaded down with trivial details, operation of management is more, recruitment is more;
The tobacco growing such as light, temperature, wet, fertile key element is affected significantly by various objective variables, and regulation and control difficulty is big;Emerge irregular, need many
Secondary thinning is filled the gaps with seedlings;Breeding time amplitude of fluctuation is big, wayward transplanting time;Hardening is cumbersome, not easy-regulating, can also damage sometimes
Tobacco seedlings;Especially in terms of tobacco seedlings quality, tobacco root system not enough flourishing, stem is very thin, regularity is not high;Disease hazard rate is higher;
Also seedling stage is long after transplanting.
