Abstract
The invention discloses a mobile light supplementing method. By constructing a ropeway and a moving motor on the roof of a greenhouse and putting light supplementing lamps on the ropeway, the light supplementing lamps can move to and fro; a day is divided into two periods of time, i.e. a period A of time and a period B of time, the period A of time is from 8:00 to 16:00, and the period B of time is from 16:00 to 8:00 in the next day; light is not supplemented in the period B of time, the light supplementing lamps start to supplement light in the period A of time when irradiation in the greenhouse is lower than a set value, at the moment, the motor is switched on, and the light supplementing lamps are dragged by the motor to move to and fro at the speed of 0.1m/s to 0.4m/s on the ropeway to supplement light to greenhouse crops; the time interval of supplementing light to the greenhouse crops is one to four minutes. The principle of the mobile light supplementing method is that light is supplemented by utilizing the different demands of the crops on light in the photosynthetic process, i.e., light is supplemented at the stage of light reaction, and is not supplemented at the stage of dark reaction. The mobile light supplementing method can increase the utilization efficiency of the individual lamps in light supplementing and reduce the energy consumption of light supplementing, the investment of light supplementing equipment and the operation cost of greenhouses, and can be applied to supplement light to greenhouse crops.
Description
Technical field
The invention belongs to facilities horticulture cultivation field, be specifically related to chamber crop light filling technology.
Background technology
Current China has become industrialized agriculture big producing country, and area and output are sure to occupy the first in the world.But the illumination in greenhouse is based on natural daylight and availability is lower.The growth relationship of illumination and chamber crop is close, catches luminous energy to greatest extent, gives full play to the photosynthesis potentiality of plant, will be directly connected to the benefit of agricultural production.In recent years, green house is produced and is generally adopted counter-seas on production, because Winter-Spring illumination is weak, causes plant growth slow, yields poorly, be therefore badly in need of carrying out light filling.
Current existing light filling measure normally installs light compensating lamp above greenhouse, starts light compensating lamp carry out light filling to chamber crop by illumination control point.Namely, when warm indoor illumination is lower than certain certain value or a certain scope, open light compensating lamp and carry out light filling.When warm indoor illumination is higher than certain certain value or a certain scope, close light compensating lamp.In greenhouse, first light filling needs to consume a large amount of electric energy, and the light compensating lamp that its secondary installation is a large amount of, each of which increases the operation cost in greenhouse, reduces the economic benefit in greenhouse.
Chamber crop is to the absorption of light, and major part is used for the photosynthesis of crop.The photosynthesis of crop is generally divided into two stages, namely
photoreaction stagewith
cloudy, turbid phase(or carbon stage of reaction);
photoreaction stagemainly
absorb luminous energy, and be unstable chemical energy by the light energy conversion of absorption, releasing oxygen simultaneously; Reaction time is very short, and 1-10 microsecond terminates, and mainly controls by illumination;
cloudy, turbid phase does not need light, and major function iscarbonic acid gas is enzymatically synthesized sugar, and is stable chemical energy by the converts chemical energy of instability, the reaction time is slow, generally needs within 2-6 minute, just can complete, mainly controls by temperature.According in chamber crop photosynthesis
different phaseto the difference of light demand, namely illumination is provided at photoreaction stage, illumination is not provided in cloudy, turbid phase, the present invention proposes a kind of method based on mobile light filling, the several times that the active area of single light compensating lamp expands as traditional light compensation method, reduce equipment investment and the light filling energy consumption of light filling, the energy-saving and emission-reduction for hothouse production provide theoretical foundation and technical support.
Patent application about chamber crop light filling is more, but most research trend is in the research of light compensating apparatus.Such as (application number: 201110450094.9), discloses a kind of supplementary lighting sources that can move left and right in greenhouse to Chinese patent " the supplementing light for greenhouse device that a kind of light source is divided a word with a hyphen at the end of a line "; Chinese patent " a kind of method and apparatus of plant intelligent light filling " (application number: 201010529814.6), disclose a kind of can according to the light compensation method of red, blue light in crop demand adjustment greenhouse and equipment; (application number: 201010585819.0) discloses a kind of light compensation method that can carry out array layout according to the ratio range of the absorption spectrum of plant chlorophyll a, b and chlorophyll a/b ratio to LED lamp mixed to Chinese patent " a kind of hothouse plants cultivation light compensation method ".Chinese patent " Intelligent plant cultivation supplementary lighting method and system " (application number: 201110162508.8) disclose a kind of method according to crop demand gradient light filling and light filling equipment.Above-mentioned patent tends to the research and development of light filling equipment mostly; Chinese patent " the intermittent greenhouse light-supplementing system that a kind of light source is divided a word with a hyphen at the end of a line automatically " (application number: 201110226107.4) disclose a kind of light filling equipment that can move left and right, this patent also tends to the research of light filling equipment, to how carrying out light filling in greenhouse does not relate to.
Summary of the invention
The object of the present invention is to provide a kind of portable light compensation method, to realize meeting chamber crop on the basis of lighting requirements, improve the utilization ratio of single lamp in light filling as far as possible, reduce light filling energy consumption and reduce input, the reduction greenhouse operation cost to light filling equipment.
In order to solve above technical problem, according to the difference to lighting requirements in crop photosynthesis process, devise a kind of light compensation method of light source movement, the concrete technical scheme adopted is as follows:
A kind of portable light compensation method, is characterized in that:
By building slip rope and mobile motor in top of greenhouse, by light filling lamp bracket on slip rope, light compensating lamp can be moved around;
One day is divided into A period and two periods of B period, the A period is 8:00-16:00, the B period is 16:00-second day 8:00;
B period not light filling, in the A period, when radiation value in greenhouse is lower than setting value, described light compensating lamp starts light filling, now described motor is opened, and under the traction of described motor, described light compensating lamp to move around the light filling realized chamber crop with the speed of 0.1-0.4 meter per second on described slip rope; The time interval of described chamber crop light filling is 1-4 minute; Described setting value is set according to crop characteristic by hothouse production person.
Light compensation method provided by the invention, its principle utilizes in crop photosynthesis process to carry out light filling to the difference of light demand.Namely at photoreaction stage light filling, at cloudy, turbid phase not light filling.
the present invention has beneficial effect
The present invention needs light according to photoreaction stage in chamber crop photosynthesis, and cloudy, turbid phase does not need light characteristic, devises a kind of light compensation method of light source movement.Invention increases the utilization ratio of single lamp in light filling, decrease the input of light filling equipment, reduce the energy consumption of light filling.
Embodiment
Below for greenhouse culture cucumber, technical scheme of the present invention is further described in detail.
First set up slip rope and mobile motor in top of greenhouse, light compensating lamp is arranged on slip rope.Remaining liquor collecting device is increased in cultivation system.
