A kind of method of green Flos abelmoschi manihot nursery
One, technical field
A kind of method that the present invention relates to green Flos abelmoschi manihot nursery, belongs to vegetable seedling-raising technique field.
Two, background technology
Green Flos abelmoschi manihot (Abelmoschus esculentus) had another name called Abelmoschus esculentus, Flos abelmoschi manihot, swordweed, for Malvaceae Abelmoschus 1 year
Or herbaceos perennial, its with tender pod for food, because of rich in proteins, carotene, vitamin C, sugar and mineral, flavone,
The multiple nutrients such as free amino acid and bioactive ingredients and enjoy people to favor.Abelmoschus esculentus is now distributed in all over the world, with heat
Band and subtropical zone are the most universal, and the most all there is cultivation China's the South and the North various places.It belongs to short-day plant, the quickest to illumination condition
Sense.China Yangtze River Delta and to the north of area, due to the restriction of the factor such as weather, illumination, Abelmoschus esculentus mainly uses and sets
Execute cultivation mode.Therefore, early spring, low light level weather became the restrictive factor cultivating healthy and strong seedling, used artificial light source regulation and control
The light control measures that breeding and seedling nursing with equipment has necessitated with cultivation.
Light both photosynthesis, or a kind of triggering signal as a kind of energy control, affects the growth of plant and sends out
Educate.Use different wave length light irradiate plant, find plant to ultraviolet light UV-A(320~380 nm), ultraviolet light UV-B(280
~320 nm), blue light (380~500 nm), HONGGUANG (620~700 nm) and far-red light (700~800 nm) especially sensitive.Its
In, blue light plays an important role at aspects such as chlorophyll formation, Development of Chloroplasts and stomatal openings.Facility cultivation utilizes
Artificial light source supplements the deficiency of natural lighting or replaces nature light to have become as the important of environmental Kuznets Curves plant growing and growth
Means.At present, the artificial light source of life-time service mainly has electric filament lamp, fluorescent lamp, high-low pressure sodium vapor lamp, metal halide lamp and dysprosium lamp
Deng, wherein high-pressure mercury lamp and dysprosium lamp are luminous efficiency and the higher light source of effective light compositing efficiency, but its emission spectrum can not
Match with the photosynthesis absorption spectrum of plant, it is impossible to plant irradiation at short distance, inefficient to plant growing light stimulus,
And heat radiation is many, efficiency is low, power consumption is big, cost is high.Therefore, introduce good luminous performance, energy-conservation, heat production is low, life-span length
New type light source, significant to the electric energy improved in botanical seedling culturing facility and space availability ratio, reduction cost.And rare earth is planted
Thing growth lamp is selection proportioning and the utilization utilizing rare-earth trichromatic fluorescent powder, recalls the spectrum needed for applicable plant growing, its
Light efficiency is evenly distributed, and is other twices with wattage electricity-saving lamp, three times of general daylight lamp, and service life is long.In recent years,
The research utilizing artificial light source to carry out environment conditioning plant growing gradually causes the concern of Chinese scholars.Scholar both domestic and external is
Through having carried out the applied research of some relative photo regulating plant growths, its partial results have proven to light to the growth promoter of plant and
Physiological property shows and remarkably promotes effect, but have also discovered different plant species or the photobiology effect of kind generation
There is notable difference.Therefore, in order to screen the artificial light source of applicable green Flos abelmoschi manihot nursery, optimize facility Flos abelmoschi manihot artificial breeding and
Cultivation system, it is necessary to the research in terms of utilizing high-quality artificial light source to carry out lighting environment control technique.
This method explores the method test of a kind of green Flos abelmoschi manihot nursery, establishes the most feasible test method, operation step
Rapid simple, test effect is stable, clear, the most either can obtain well should in scientific research, detection and student test
With.
Three, summary of the invention
Technical problem it is an object of the invention to provide a kind of method of green Flos abelmoschi manihot nursery.
Technical scheme
1, a kind of method of green Flos abelmoschi manihot nursery, comprises the following steps:
1) preparation of seedling: select green Flos abelmoschi manihot seed of the same size, be sown into substrate be the Vermiculitum+peat composed of rotten mosses+Nutrition Soil (1.5V:
In hole tray 1.5V:1V), and hole tray is suspended in the Turnover Box filling water and carries out water planting nursery, after 7-10d cotyledon flattens,
Transplant to be grown to 2-3 sheet true leaf in the nutritive cube that substrate is the Vermiculitum+peat composed of rotten mosses+Nutrition Soil (1.5V: 1.5V:1V);
2) light source processes: be then positioned over by the green Flos abelmoschi manihot seedling with 2-3 sheet true leaf under the rare-earth plant light of bluish red combination 2:8
Cultivate, keep light intensity to be 100 μm ol/ m2S, the photoperiod is 12 h/d, carries out often watering Hoagland ' s nutritional solution
Regulating reason, ambient temperature keeps 24~26 DEG C, and relative humidity is 55%~60%, processes 45 d;
3) light source: the light source of described photo-irradiation treatment is a group rare-earth plant light source, described light intensity is the number by adjusting lamp
Amount controls with the distance of lamp to influences of plant crown, and the described photoperiod uses a timing means to control.
Beneficial effect
A kind of method that the invention provides green Flos abelmoschi manihot nursery.The method for culturing seedlings of the present invention has the advantage that 1) simple to operate,
Effective;2) energy environment protection is saved;3) plant strain growth is the most healthy and the strongest.The inventive method and result are for carrying out and green Flos abelmoschi manihot nursery phase
The Olericulture research and development closed provides new approach and foundation.
