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
