With the development of modern tobacco agriculture, a large amount of seedling raising greenhouse has been built in national each tobacco leaf producing region in succession, is roasting
Cigarette intensive seedling production provides important facility guarantee.Tobacco workshop floating seedlings have intensive degree high,
Save seedbed；Simplify tobacco seedlings management, improve planting percent；Reduce and transplant the advantage such as recruitment, shortening seedling-slowing stage,
There is wide development and application prospect.But due to, the seasonality of leaf tobacco production, major part cigarette facility purposes
Single, standby time is long, and maintenance cost is high, causes these assets to produce seasonality idle.Cause stealth
Waste.Not only reduce assets utilization efficiency, waste the land resource of preciousness.Do seedling raising greenhouse well to combine
Closing and utilizing, with short production cycle, warp can be cultivated by productive assets facility in comprehensive utilization nursery workshop of suiting measures to local conditions
The Ji flowers of high efficiency and security are high, the low organic vegetable class of agricultural chemicals harm, and can not only make full use of can be through
Battalion's property assets, widen tobacco leaf cooperative society and increase income channel, solve the funds source that nursery workshop renewal of facility is safeguarded
Problem, increases nursery workshop and baking workshop service life and efficiency, owing to flue-cured tobacco booth ground is compact soil
Layer or cement flooring, later use not can use soil, meanwhile, for preventing pest and disease damage to infect tobacco seedlings, right
Extraneous entrance booth material sterilization requires strict, can only introduce the artificial soil not having pest and disease damage to pollute.Crop
Growing in the artificial soil do not have seepage, substantially not having fertilizer loss, flue-cured tobacco seedling-cultivating greenhouse cultivation crop is
Under enclosed environment, extraneous pest and disease damage can be cut off and infect, and the matrix of plant growth is not polluted, and makees
The required moisture of thing growth, from well water or running water, can not use or minimally use agricultural chemicals, not only
The method of cultivation is green, environmental protection, does not produce soil and groundwater source and pollutes.And the organic vegetable cultivated
Class security is high, and agricultural chemicals harm is low, has ensured that edible crowd's is healthy, adds rural area employment, subtracts
Lack land resource waste.Thus utilize flue-cured tobacco booth to carry out arable farming, producing green, environmental protection agricultural production
Product aspect is also that general organic farming facility hardly matches.
