Description
Technical field
The invention belongs to Environment Controlled Agricultural Facility fields, and in particular to a kind of cultural method and device for preventing fruits and vegetables calcium deficiency.
Background technique
Acalcicosis caused by plant is lacked of proper care due to calcium is one of the most common type physiological disturbance in industrialized agriculture production.It lacks
The feature that calcium disease shows between different plant varieties is also different, and such as the dry combustion method disease that lettuce shows, tomato, the navel of capsicum are rotten
Disease, the brown spot of potato, bitter pit and the black heart of pear of apple etc..Calcium imbalance can cause cell membrane, cell wall structure
With the destruction of function, separate living tissue necrosis, plant blade tip or leaf margin is caused to turn yellow, thus seriously affect the exterior quality of fruits and vegetables,
Mouthfeel and commodity value.Therefore, the regulatory mechanism of calcium ion in plant is studied, the generation of preventive device fruits and vegetables calciprivia is right
It improves fruit-vegetable quality and yield is of great significance.
Summary of the invention
Cause acalcicosis disease because calcium is lacked of proper care for prevention fruits and vegetables, the present invention discloses a kind of cultivation side for preventing fruits and vegetables calcium deficiency
Method and device are lacked by using the high-frequency electric field of the intrinsic potential fluctuation of plant can be caused to regulate and control fruits and vegetables cultivation to prevent fruits and vegetables
Calcium avoids disease, promotes yield.
In order to achieve the above objectives, the present invention adopts the following technical scheme:
A kind of cultural method preventing fruits and vegetables calcium deficiency, to utilize type plant using type plant factor or artificial light in sunlight
It is perpendicular between the earth to generate it by the electrode gauze for the electrode gauze of erection level above the fruits and vegetables cultivated in factory
Straight downward voltage is 15~45kV, the high-frequency electric field that frequency is 0.1~10Hz, the electric field and the intrinsic potential fluctuation frequency of plant
It is similar, the intracorporal calcium ion of plant is regulated and controled by the high-frequency electric field, to prevent fruits and vegetables calcium deficiency.
Further, the voltage of the electric field is preferably 30~45kV, and frequency is preferably 1~10HZ.
A kind of culture apparatus preventing fruits and vegetables calcium deficiency, including a power supply and an electrode gauze；The cathode of the power supply passes through one
Grounding electrode line ground connection, anode connect the electrode gauze；It is equipped between the power supply and the electrode gauze and adjusts the supply frequency
A control device；Excessively several insulators of the electrode wires Netcom are fixed on above cultivated fruits and vegetables, are used to form itself and the earth
Between an equally distributed electric field；The electric field is 15~45kV for a voltage under the adjusting of the control device, frequency is
The high-frequency electric field of 0.1~10Hz, the electric field are similar to the intrinsic potential fluctuation frequency of plant.
Further, for the culture apparatus for sunlight using in type plant factor, the electrode gauze is located at this too
Sunlight is using in type plant factor.
Further, for the culture apparatus for artificial light using in type plant factor, the electrode gauze is located at the people
Artificial light source lower section of the work light using type plant factor, one graphite electrode of the grounding electrode line connection, graphite electrode insertion
In nutrient solution of the artificial light using the nutrition liquid bath of type plant factor.
Further, a metal mesh is equipped between the electrode gauze and the artificial light source.
Electric field used in plant culture is just with electric field strength in the prior art and there are the time promotes plant raw
Long and disease prevention, the advantages of such as using electrostatic field or low frequency electric field, do not make full use of high-frequency electric field, to calcium ion tune
Section effect is poor, and Calcium-ion absorption rate is low, bad to fruit and vegetable physiological regulation venereal disease evil preventive effect, and plant photosynthesis facilitation effect is also unknown
It is aobvious.Compared with prior art, the cultural method use of prevention fruits and vegetables calcium deficiency provided by the invention can cause the intrinsic potential wave of plant
Dynamic high-frequency electric field, to regulate and control calcium ion missing and promote fruits and vegetables yield, fruit and vegetable physiological regulation venereal disease evil preventive effect and cultivation effect
It is excellent.Its principle are as follows: there is low pressure forward direction atmospheric electric field in nature, the ionosphere in earth atmosphere has relative to ground
The positive potential of 360kV, the field strength of Near Ground are about 120Vm-1, also there is the potential difference of 70~80mV inside and outside plant soma.
Tellurian phytomorph structure and growth and development etc. will not only adapt to environment of electric field, and many functions such as nutrient transport, energy turn
Change, information transmitting etc. also need charge movement assist to complete.The direction of electric field change and size are that plant absorbs calcium ion
Key parameter, the current level difference generated under electric field action can change the film potential of cell, not only affects cell membrane
Permeability causes the redistribution of ion in plant, further improves the ability that cell absorbs and operates substance, and then influences to plant
Absorption and transport of the object to ion.Electric field may also regulate and control the absorption and transport of calcium ion by influencing plant transpiration.?
Under electric field action, air is ionized to many free ions and electronics, and the steam in air is by the ion and electronics of high-speed motion
Charge is obtained after collision, and polywater effect occurs under the action of electric field Coulomb force, improves the steam-laden pressure difference of air
(VPD) transpiration of plant is affected in turn, and higher transpiration accelerates absorption of the plant to calcium ion.
The present invention, which is used, regulates and controls the intracorporal calcium ion of plant with the high-frequency electric field of the intrinsic potential fluctuation similar frequencies of plant, in advance
Anti- facility leaf vegetables leads to the generation of acalcicosis due to calciprivia.And type and people are utilized according to different facility types, such as sunlight
Work light utilizes type plant factor, and different culture apparatus is arranged.
