Abstract
The invention discloses a method for restraining plant vain growth through an LED lamp. The method is implemented by using the LED red light to carry out multipoint interruption to the dark period of the plant growth every 1 to 4 hours; the used light intensity is 10 to 200 Mu mol/m<2>*s<-1>, and the lighting time is 5 to 20 minutes. The method for restraining plant vain growth through the LED red light has the advantages that the problem that young seedling vain growth is easily caused by poor lighting environment and hot and humid environment for growing seedlings in a facility greenhouse is solved; therefore, compared with the conventional method that the vain growth is restrained through a plant growth regulator, the method provided by the invention suits the purpose of develop green organic agriculture on one hand and provides a theoretical basis for the industrialized seedling production and the development of a plant factory on the other hand.
Description
1 technical field
The invention belongs to illuminating product in the application of agriculture field, relate to the control of plant excessive growth problem, particularly a kind of method for suppress vegetable seedling excessive growth in the Greenhouse by the LED lamp.
2 background technologies
Facility cultivation is a kind of controlled agricultural, claims again environment conditioning agricultural, can alleviate to some extent or prevent that disastrous weather and adverse environment condition are to the harm of agricultural production under the open country working condition.China is the country of world's facility cultivation area maximum, and Protected Production of Vegetables has become pillar industry in many provinces and cities agricultural and the main path of farmer richness.
Luminous environment in the facility has significant impact to the growth of vegetables, and regulating luminous environment is the most important condition that realizes high yield and high quality.Along with the development of modern agriculture, grow seedlings already through becoming the new industry of the vigor of having much.The low-cost high-quality seedling of large-scale production is the research emphasis of nursery industry, also is the important goal of modern seedling growing process.Because the morphogenesis of seedling is an irreversible process, the healthy and strong degree of the seedling of cultivating will directly affect growing of plant, and closely related with the yield and quality of crop.Because protected crop is off-season cultivation, and winter, light application time was short, plastic film and Insulation cause illumination wretched insufficiency in the booth.Such as the moon, rain, snow, greasy weather gas, or south China is cloudy and drizzly for days on end, plum rain season, lacks optical phenomenon in greenhouse, the booth more serious, and intensity of illumination and light application time are obviously not enough, are easy to cause seedling excessive growth.
The artificial light source that uses at agriculture field for a long time mainly contains high-pressure mercury lamp, fluorescent lamp, metal halid lamp, incandescent lamp etc., and the outstanding shortcoming of these light sources is that energy consumption is large, operating cost is high, and energy consumption cost accounts for 50%～60% of whole operating costs.And novel artificial light source led spectrum is narrower, compact conformation, and its cold light source characteristic makes it can the irradiation at short distance plant, thereby the light source that can be used as the cultivation of high density stereoscopic frame improves land utilization rate.Along with the raising of LED production technology and the continuous decline of price thereof, LED is used in agricultural production more and more widely.
And the method for tradition by plant growth regulator suppresses excessive growth and we and develops the green organic agricultural purpose and disagree, therefore utilizing LED light control technique to cultivate strong sprout is energy-saving and environmental protecting, economical and effective and simple and easy to do new method, has outstanding advantage.
3 summary of the invention
The problem that the present invention solves is to provide a kind of facilities vegetable to grow seedlings to suppress the method for seedling excessive growth, regulate and control establishing of seedling morphology by LED light, for factorial seedling growth production and plant factor's development provide theoretical foundation.It not only matches with the development green organic agricultural, and is energy-saving and environmental protecting, economical and effective and simple and easy to do new method.
This invention is to be achieved through the following technical solutions:
A kind of method that suppresses plant excessive growth by the LED lamp, the method be by with LED ruddiness with dark phase of plant growth according to interrupting to realize every 1～4 hour multiple spot, the use light intensity is 10～200umol/m
2S
-1, light application time is 5min～20min.
Described LED lamp is panel light, is mainly made by LED red light chips and aluminium alloy extrusions, and LED red light wavelength scope is between 600～700nm, and maximum absorption wavelength is near 660nm.
Described multiple spot interrupts, light intensity and light application time can realize by control system.
Compared with prior art, the present invention has following useful technique effect:
1, the method that suppresses plant excessive growth by the LED lamp provided by the invention has overcome conventional method and uses plant growth regulator to the drawback that plant has side effects, and uses up the regulating plant morphological development, meets the thinking of development of green agriculture.
2, this LED panel light light quality provided by the invention is pure, energy-saving and environmental protecting, and manufacture craft is simple.
3, the method for this inhibition plant provided by the invention excessive growth can realize under low light quantity condition, and is economical and practical.
4 description of drawings
Fig. 1 is the structural representation of LED lamp of the present invention, is comprised of 1-LED red light chips, 2-aluminium alloy extrusions and 3-control system etc.
