Description
Technical field
The present invention relates to a kind of technical field of agricultural greenhouse soilless culture, refer to utilize solar energy soil-less cultivation drip irrigation system and control method thereof especially.
Background technology
New world has been opened up in the application that develops into cultivation technique without soil of China's industrialized agriculture.Since reform and opening-up, along with constant development of economy, the improving constantly and development that town and country " vegetable basket project " builds of living standards of the people increases the increasing demand of quality vegetables.Therefore, the protection of vegetables and other economic crops ground area under cultivation enlarges rapidly.The development of plastic tunnel culture underglass is for the high-qualitys of horticultural crops such as vegetables, flowers, economic crops, precocity, high yield with in different regions, Various Seasonal carries out off-season cultivation and created condition.
Yet because the restriction of fixation means such as booth and the high benefit of booth culture underglass, many batches of crop rotations inferior, that carry out science are very difficult.The result of long-term continuous cropping makes the soil-borne disease insect pest serious day by day, forms " continuous cropping in the facility cultivation is hindered ", and further developing of ground cultivation protected in influence; Booth has the more significantly big high yield of soil cultivation also to be very limited on the other hand; Moreover owing to particularly soil pollution of the environmental pollution of following industrial development to bring; Brought very big difficulty for production high-grade, pollution-free vegetable; And in horticultural facilities such as booth, carry out soilless culture, and can carry out in soil such as the serious place of deserted mountain, sandy beach and soil pollution that should not farming on the one hand, avoid and overcome soil continuous cropping hindering.Can give full play to the superiority of facility cultivation and soilless culture on the other hand, produce the product of high-quality, high yield.Therefore, use soilless culture in the facility cultivation and more can bring into play better effect.
Soilless culture is an emerge science technology that on the basis of mineral nutrition of plant research, grows up. it is without natural soil; Use chemical solution (nutrient solution) cultivated plant fully; This nutrient solution can replace natural soil to crop moisture, nutrient, oxygen, temperature to be provided, and makes the crop can normal growth and accomplish its whole life.
At present, cannula type bag cultivating technology is the novel soilless culture system that on the basis that does not occupy cultivated land, grows up, and has to reduce production costs, and simplifies culture technique, improves the distinguishing feature of vegetable yields and quality, more and more receives vast farmers friend's welcome.
Summary of the invention
The present invention utilizes solar electrical energy generation as the energy; In plastic tunnel, be provided with liquid storage tank; Establish the inorganic matrix bag by planting the row of asking, the ratio in three in the inorganic matrix bag is loaded gravel, vermiculite, perlite compound, and anti-sewer is set below the inorganic matrix bag; And communicate with the backflow barrel, the backflow barrel links to each other with liquid storage tank; Lay black plastic drip irrigation pipeline on the inorganic matrix bag both sides of arranging, the drip irrigation mouth is inserted in the inorganic matrix bag; In the inorganic matrix bag, install several humidity sensors additional, be used to detect the humidity of cultivation with inorganic matrix; When the humidity of inorganic matrix bag reaches the following value of a setting; The data that humidity sensor detects are transferred in the processor of single chip computer through A/D converter; Single-chip microcomputer sends instruction according to data and opens electromagnetic switch; Nutrient input is delivered to the drip irrigation pipeline in the electric pump extraction pond on the startup liquid storage tank, by the drip irrigation mouth that is inserted in the inorganic matrix bag root system of plant is carried out automatic dripping irrigation again; When drip irrigation to a certain degree, the humidity of inorganic matrix bag has reached one and has gone up value, the data that humidity sensor detects are transferred in the single-chip microcomputer through A/D converter, single-chip microcomputer sends to instruct and cuts out electromagnetic switch and stop drip irrigation.The nutrient solution of drip irrigation seepage can trickle through the antiseepage ditch below the inorganic matrix bag in the backflow barrel; Again by the backflow barrel liquid storage tank that trickles back; Form benign cycle and utilize again, required nutrient solution fully is provided so promptly for crops, can save the consumption of nutrient solution again.
The present invention from cultivation, growing into each link of gathering can both be according to the needs of crop growth, by Single-chip Controlling monitor, regulation and control and nutrient fluid drip irrigation automated job, thereby have general traditional soil cultivation incomparable superiority.
The present invention can save conventional energy resource in a large number, makes full use of the energy of reproducible solar electrical energy generation as single-chip computer control system and electric pump power, and free use renewable energy resources that can be endless reaches the purpose that reduces production costs.
The present invention is provided with anti-sewer and backflow barrel, can significantly reduce the loss of nutrient solution in the drip irrigation, saves manpower, the saving resource, have pollution-free, the characteristics of energy-saving and environmental protection.
The present invention need not to take agricultural and ploughs, and does not receive the restriction of conditions such as area, space, soil.Can in the place that can't plant such as roof, desert island, saline land, desert, tidal land and soil be extremely barren and the plantation of the plot of severe contamination.
To achieve these goals, technical solution of the present invention is: the first step, and set up photovoltaic row group, batteries, inverter controller to be used to provide electric energy; Second step, establish the inorganic matrix bag by planting the row of asking, the ratio in three in the inorganic matrix bag is loaded gravel, vermiculite, perlite compound; Anti-sewer is set below the inorganic matrix bag; And communicate with the backflow barrel, the backflow barrel links to each other with liquid storage tank, forms the nutrient solution benign cycle and utilizes; The 3rd step was provided with the nutrient solution liquid storage tank in plastic tunnel, lay black plastic drip irrigation pipeline on the inorganic matrix bag both sides of arranging, and the drip irrigation mouth is inserted in the inorganic matrix bag; The 4th step was provided with single-chip microcomputer, A/D converter, in the inorganic matrix bag, installed several humidity sensors additional, was used to detect the humidity of cultivation with inorganic matrix; The 5th step, on the nutrient solution liquid storage tank, electric pump is installed, and before electric pump drip irrigation pipeline, is added fixed filter, be used for filtering the nutrient solution residue, prevent the clogging drip irrigation mouth, the opening and closing that electromagnetic switch is used to control electric pump are set on pipeline; The 6th step; Humidity sensor circuit, electric pump circuit are connected with single-chip microcomputer; When the humidity of inorganic matrix bag reaches one down during value, the data that humidity sensor detects are transferred in the processor of single chip computer through A/D converter, and single-chip microcomputer sends instruction unlatching electromagnetic switch according to data; Nutrient input is delivered to the drip irrigation pipeline in the electric pump extraction pond on the startup liquid storage tank, by the drip irrigation mouth that is inserted in the inorganic matrix bag root system of plant is carried out automatic dripping irrigation; Otherwise, stop drip irrigation.
