Description

A kind of method that adopts the rare-earth plant growth lamp to carry out the Radish Sprouts indoor production

Technical field

A kind of method that adopts the rare-earth plant growth lamp to carry out the Radish Sprouts indoor production, belong to biological technical field.

Background technology

The light source of Radish Sprouts production and application mainly relies on sunshine at present, utilizes the rare earth artificial light source to there is not yet report at the indoor culture Radish Sprouts.

Only affect the most important envirment factor of plant growth, plant is accepted the variation of light quality, light intensity and light application time by light receptor, the aspects such as regulation and control are grown, morphogenesis, photosynthesis and metabolism.Along with the progress of science and technology and the fast development of agricultural and biological industry, plant has broken through the restriction of simple dependence sunshine to the utilization of efficient light, artificial light source replaces or the deficiency of supplementing lamp has become environment and controls the important means of growth and development of plants.Artificial light source in agricultural and biological field use mainly contains fluorescent lamp, incandescent lamp, sodium vapor lamp and dysprosium lamp etc. for a long time, wherein high-pressure mercury lamp and dysprosium lamp are luminous efficiency and the higher light source of efficient light combined coefficient, but power consumption is large, emission spectrum can not match with the photosynthesis absorption spectrum of plant well, does light filling efficiency low; And produce a lot of thermal radiation, and can not approach irradiation to plant, not high to plant growth light stimulus efficiency, do artificial light source cost very high.Therefore, introduce that energy-conservation, good luminous performance, quantity of heat production are low, the new type light source of long service life, to improving utilization rate of electrical in plant factor and space availability ratio, reduction power consumption cost is significant.

The rare-earth plant growth lamp is selection proportioning and the utilization that utilizes rare-earth trichromatic fluorescent powder, mediates and is fit to the required spectrum of plant growth.The light efficiency of this light irradiation is uniformly distributed, and light efficiency is other twice with the wattage electricity-saving lamp, is three times of general fluorescent lamp, and long service life.Therefore, the artificial light source that utilizes the characteristic of property of rare-earth plant growth lamp to develop plants to need will improve its optical energy utilization efficiency greatly.

Summary of the invention

The object of the present invention is to provide a kind of method that adopts the rare-earth plant growth lamp to carry out the Radish Sprouts indoor production, the present invention both can be used for the production of Radish Sprouts, also can be used for the scientific research of Radish Sprouts.

Technical scheme

A kind of method that adopts the rare-earth plant growth lamp to carry out the Radish Sprouts indoor production comprises following content:

1. presoaking and germinating: seed will select purity, cleanliness good, and germination rate is high, full seed.First carry out prior to seeding seed and clean, reject the seed of damaging by worms, breaking residual, lopsided, rotten, flat grain, special granule and germinateed., for promoting seed sprouting, also need to soak seed.First with the clean clear water of 28-30 ℃, seed is eluriated 2-3 time, radish is soaked 6-8 hour.Seed soaking is eluriated 2-3 time again with seed after finishing, and drains excessive moisture.First plastics seedling dish is sterilized with limewash or bleaching powder before sowing, then with clear water, wash down, then at paving layer 2-3 old newspaper or the blotting paper of trying to get to the heart of a matter, radish seed can be sowed.Require during planting seed to sow seeds evenly,, so that the growth of bud seedling is neat, sows above complete rear seedling-cultivating tray and cover again wet gunny sheet or old newspaper.Seeding quantity is determined according to kind.After the vernalization sowing is complete, the seedling dish is stacked together, fold dish vernalization.Germination temperature keeps 24-26 ℃, and humidity is 65-75%, and during the vernalization of folded dish, spray water 2-3 every day, and the water yield is not excessive, in order to avoid rotten bud.Water the water yield matrix be moistening to spray in rear seedling dish, a little minim water of paper is advisable in the seedling dish.Should carry out once the transposing of seedling dish position up and down in water spray, make seedling dish planting environment of living in as far as possible evenly, promote the bud seedling neatly to grow.Under normal operation, can finish vernalization about 4 days.After 5-6 days, cotyledon flattens.

2. light treatment: the radish seedling after cotyledon is flattened is positioned under the rare-earth plant growth lamp of blue red combined light B:R=15:85 and cultivated 15 days.

3. the condition of light treatment: light intensity is set to 2800 lux, and the photoperiod is 12 hours, 25 ± 1 ℃ of cultivation temperature, and humidity remains on 70 ± 5%.

4. control method:

1. the light source of described light treatment is a group rare-earth plant lamp;

2. described light intensity is to control to the distance of influences of plant crown by quantity and the lamp of adjusting lamp;

3. the described photoperiod adopts a timing means to control.

5. radish seed is the tank radish.

Beneficial effect

A kind of method that adopts the rare-earth plant growth lamp to carry out the Radish Sprouts indoor production has the following advantages: 1) simple to operate, effective; 2) save energy environment protection; 3) plant strain growth is healthy and strong fast.The inventive method and result provide reliable technical scheme for the Radish Sprouts indoor production, and also the Olericulture research for bud seedling dish provides new research platform.
