Description
Technical field
The invention belongs to industrialized agriculture production fields, and in particular to the cultural method of romaine lettuce in a kind of plant factor.
Background technology
Plant factor is a kind of new and effective facilities horticulture production model, not by or seldom restricted by natural conditions, be
Generally acknowledged industrialized agriculture superlative degree developing stage in the world.It passes through illumination in intelligence control system control facility, temperature, wet
Degree, CO2The environmental elements such as concentration and nutrient solution create suitable condition for growth and development of plants, and efficient production are combined to count
It draws, and realization crop anniversary continuous production (Liu Wenke etc., 2014, illuminating engineering journal, 25 (4):50–53).
Plant factor can be divided into artificial light type plant factor, sun light type plant factor and too according to illumination source
Sunlight and artificial light and with three kinds of type plant factor.Artificial light type plant factor is mainly used for the shorter leaf vegetables vegetable of growth cycle
The production of dish, wherein romaine lettuce are one of Main Cultivation vegetables.Layer stereo high-density planting is used in artificial light type plant factor
Pattern improves land utilization ratio, increases yield, but high planting density also brings some drawbacks, in influences of plant crown lower part
Outer foil causes illumination insufficient due to being blocked by top vane and surrounding plant, it may appear that photosynthetic rate reduction, blade
The phenomenon that aging shifts to an earlier date.The phenomenon not only seriously affects romaine lettuce yield, but also needs to remove aging siphonal lobe before listing, and also increases
The input of manpower and time are added.How to improve romaine lettuce plant siphonal lobe luminous environment, delay siphonal lobe aging, reduces waste leaf loss amount,
It is the active demand of vast production grower.The solution of the problem can improve romaine lettuce yield, and then increase artificial light type plant work
The output capacity and economic benefit of factory push the popularization and development of artificial light type plant factor.
Invention content
Goal of the invention：Present invention aims at the cultural method for providing romaine lettuce in a kind of plant factor, to existing artificial
Light cultural method is improved, and using by the way of the light filling of plant bottom, improves the luminous environment of romaine lettuce siphonal lobe, it is net to improve siphonal lobe
Photosynthetic rate, Delaying Leaf-Senescence process reduce waste leaf loss amount, to increase romaine lettuce yield.
Technical solution：The cultural method of romaine lettuce in plant factor of the present invention, including：
(1) Pregermination and seedling breeding；
(2) it will be cultivated on the romaine lettuce seedling replanting to the cultivating stand of plant factor cultivated, 14~21 before culture
It carries out top light photograph, and the top light of resynchronisation progress later is shone and bottom light filling, bottom light filling harvest after 10~17 days；
Wherein, the direction of illumination that top light is shone is to be irradiated from romaine lettuce top to bottom；When the light filling of bottom, the irradiation side of illumination
To be irradiated from romaine lettuce bottom to top, intensity of illumination is 30~40 μm of olm-2·s-1, light application time is 12~16h/ days.
In step (1), seeding and seedling raising will be carried out after romaine lettuce presprouting of seeds, rearing condition is that intensity of illumination is 340~350 μ

The intensity of illumination that the top light is shone is 200~300 μm of olm-2·s-1, light application time is 12~16hd-1；
Preferably, intensity of illumination is 200 μm of olm-2·s-1, light application time 16hd-1。
The temperature of the culture is 20~25 DEG C, and relative humidity is 60~65%, CO2A concentration of 800~1000 μm of ol
mol-1；Preferably, the temperature of the culture is 20~22 DEG C, CO2A concentration of 1000 μm of olmol-1。
In the present invention, the blade of whole strain romaine lettuce plant is divided into 6 layers from outer layer to internal layer, wherein from the 1st of outside number
Belong to siphonal lobe to the 8th leaf, the 9th to the 18th leaf belongs to internal lobe, and every layer of blade includes 2-3 piece leaves.
Compared with prior art, beneficial effects of the present invention are：
1, waste leaf loss late is reduced, commodity leaf-making quantity is improved.Using the method for the present invention plant is carried out in the Growth of Lettuce later stage
The upward light filling in bottom can improve the Net Photosynthetic Rate of siphonal lobe, effectively delay outer senescence of leaves, reduce waste leaf loss late 5.7%,
Improve yield 17.9%.
2, scale, standardized production are easily achieved.It, can be direct since LED is light, small, easy to install, fever is few
On the field planting plate of romaine lettuce in cultivation system, according to production grower's demand, light is automatically adjusted using intelligent control system
The open and close in source, to realize scale, standardized production.
3, environmentally protective.The LED of use has many advantages, such as efficient, energy-saving and environmental protection, long lifespan, and entire light filling process is to ring
It does not pollute, is safe in border.
4, bottom light filling is carried out with top light according to synchronous, first, for the ease of management, second is that due to artificial light type plant work
The principal light source of factory is artificial light source, and energy consumption and economic input are larger, but it uses and is completely closed form production, not certainly by the external world
The influence of right photoperiod, therefore can select to open illumination (the idle electricity consumption period electricity charge are cheap) in the idle electricity consumption period, it is maximum
Limit reduces electric cost, and then increases economic benefit.
