Description
Technical field
The utility model relates to installment agriculture growth field more particularly to heliogreenhouse high yield water-saving cultures, specially
A kind of heliogreenhouse subregion trickle irrigation and carbon dioxide add rich system.
Background technique
2015, the Ministry of Agriculture made《The Ministry of Agriculture is about the implementation meaning for accomplishing fluently agricultural non-point source pollution prevention and treatment assault of fortified positions
See》, be distinctly claimed the year two thousand twenty, realize the target of " it is basic that a control two subtracts three ", explicitly point out water use efficiency to be improved and
Realize the zero growth rate of fertilizer application amount.Facilities vegetable industry in China's is to pursue economic benefit in recent years, the increase irrigation volume of blindness,
It is low to bring water use efficiency, a series of problems, such as quality of vegetable is poor, soil texture is deteriorated.
To improve water use efficiency, deficit irrigation technology is come into being, and this insufficient irrigation mode can give crop
The appropriate arid stimulation of root system reduces transpiration first is that adjusting air cap opening and closing in the plant vegetative growth stage, reduces moisture
Consumption improves water use efficiency, reduces redundancy growth；Second is that promoting the growth of plant root, increase rhizosphere range, improves and plant
Strain is tested and has been explored in the various plants such as cucumber, grape, pimento, tomato, carrot to the utilization efficiency of liquid manure.
Although deficit irrigation plays water-saving result, yield declines.
It proposes the concept of controlled alternate irrigation again later, improves water use efficiency for China's agricultural, maintain punja
Area's agricultural sustainable development provides feasible thinking.But the controlled alternate irrigation technology applied at present still has not
Foot can make certain plant the phenomenon that early ageing occur, and the process of its aging will be faster than the plant of normal irrigation processing, cucumber tool
The present main stem internode elongation of body surface slows down, blade moves back greenish-yellowization is accelerated, Newborn Leaves extension is slow etc.；By counting the whole knot melon phase
Yield data discovery, knot melon latter stage, using existing alternatively drip irrigating handle plant yield be less than normal irrigation processing
Plant, this crop early ageing and underproduction phenomenon generated under controlled alternate irrigation processing, is referred to as controlling and alternately fills
Irrigate " side effect " of technology.
Summary of the invention
In view of the shortcomings of the prior art, the utility model provides a kind of heliogreenhouse subregion trickle irrigations and carbon dioxide to add rich system
System, had not only improved crop yield in heliogreenhouse, but also improve efficiency of water application.
The utility model is achieved by the following technical solution, and provides a kind of heliogreenhouse subregion trickle irrigation and carbon dioxide
Add rich system, including subregion drip irrigation appliance and carbon dioxide enrichment device, the subregion drip irrigation appliance includes being arranged in cultivating bed
In intermediate drip irrigation zone and the intermediate drip irrigation zone two sides and the side drip irrigation zone parallel with intermediate drip irrigation zone, the centre are set
Water dropper on drip irrigation zone is interspersed with the water dropper on the drip irrigation zone of side, and in the water dropper spacing and side drip irrigation zone on intermediate drip irrigation zone
Water dropper spacing it is different；The carbon dioxide enrichment device include the caisson for being connected with outlet pipe, be mounted on it is described go out
Solenoid valve in feed channel, and the time switch being electrically connected with the solenoid valve.
This programme carries out subregion trickle irrigation by using the drip irrigation of three drip irrigation zones, and the water dropper on intermediate drip irrigation zone with
Water dropper on the drip irrigation zone of side is interspersed, and makes water dropper is triangular in shape to be interspersed, and reduces wet between three water dropper on drip irrigation belt
Cutting edge of a knife or a sword overlapping, reduce moisture vertical migration it is too fast caused by leakage, intermediate drip irrigation zone and two sides drip irrigation zone is used alternatingly in when irrigation；
Carbon dioxide is controlled to the indoor discharge of sunlight by setting time switch, it is higher to the controllability of CO2 emissions,
It is combined with the trickle irrigation of subregion, under the premise of irrigation volume is constant, makes cultivated crop yield and water utilization effect in heliogreenhouse
Rate greatly improves.
As optimization, the spacing of water dropper is 15cm on the intermediate drip irrigation zone, and the spacing of water dropper is 30cm on the drip irrigation zone of side,
The spacing of intermediate drip irrigation zone and side drip irrigation zone is 20cm.The spacing setting of this prioritization scheme can make feelings identical in irrigation quantity
Wetting front between lower three water dropper on drip irrigation belt of condition is overlapped minimum, seeps caused by reduction moisture vertical migration is too fast to the greatest extent
Leakage.
Preferably, the caisson includes several carbon dioxide steel cylinders, the gas outlet connection of each carbon dioxide steel cylinder
To the solenoid valve.The air-out apparatus of this preferred embodiment is at low cost, ensure that enough tolerance, avoids frequently replacing.
As optimization, several equally distributed ventholes are offered on the outlet pipe.It can make carbon dioxide gas
In uniform discharge to heliogreenhouse.
Existing alternate irrigation technology can lead to the closing of plant leaf blade air cap, in the influence net photosynthesis speed of lower degree
Transpiration rate is significantly reduced while rate, to achieve the purpose that water-saving.By analyzing existing photosynthetic number it has been found that existing friendship
There is surplus for the plant photochemical energy of irrigation technique processing, superfluous excitation can be scattered and disappeared by the approach of heat dissipation；And it sends out simultaneously
Now reduced using the Net Photosynthetic Rate of the plant of existing alternate irrigation technical treatment（It is reduced by its Net Photosynthetic Rate same
When, stomatal conductance and intercellular CO2Also it reduces simultaneously, it is known that be that stomatal factor limits its Net Photosynthetic Rate）, the reason is that intercellular CO2
Concentration limits the Net Photosynthetic Rate of the plant of alternate irrigation technical treatment and continues to increase, and carbon assimilation process is obstructed, result in
The accumulation of NADPH, ATP ultimately cause non-ring type electron transport chain and are obstructed, and superfluous excitation can must be dissipated by heat dissipation approach
It loses.
The beneficial effects of the utility model are：Air and intercellular CO are improved by carbon dioxide enrichment device2Concentration difference increases
Big intercellular CO2Concentration, compensation is since stomatal resistance increases bring carbon assimilation insufficient raw material, while reducing transpiration rate not
Photosynthetic carbon assimilation is influenced, achievees the purpose that water-saving and yield-increasing；Meanwhile to reduce the ratio of iirigation water source leakage, planted in heliogreenhouse
Drip irrigation technique is used under the conditions of training, more accurately drip irrigation zone setting spacing and water dropper spacing, propose the irrigation mould of subregion trickle irrigation
Formula, cooperation carbon dioxide adds rich measure, under the premise of irrigation volume is constant, makes cultivated crop yield and moisture benefit in heliogreenhouse
It is greatly improved with efficiency.
