Description
Technical Field
The invention relates to the field of vegetable planting.
Background
Soilless culture refers to a method for cultivating and growing seedlings of crops by using a substrate and the like without using natural soil, is mainly applied to the production of fruits, vegetables or flowers and plants, and is a high-yield high-quality advanced culture technology which saves water, fertilizer and labor. Soilless culture is divided into two categories, namely nutrient solution culture, namely a soilless culture mode using a nutrient solution prepared from water and a chemical fertilizer, and organic soilless culture, namely a culture mode using a clean organic substrate such as turf, organic compost and organic extract without using the nutrient solution. With the scientific and technological progress of research on plant nutrition and resource development and utilization in agricultural ecosystems, we can go from traditional soil cultivation to inorganic nutrient solution soilless cultivation to organic soilless cultivation. At present, the soilless culture substrate culture by using the inorganic nutrient solution is widely applied at home and abroad, which is a mode with the largest popularization area in the soilless culture. The root system of the crop is fixed in an organic or inorganic matrix and is supplied with the crop nutrient solution by a drip irrigation or trickle irrigation method.
And the nutrient solution is if long-time stay in the root of leaf lettuce, can breed the bacterium very easily, and the nutrient solution is deposited in the matrix too for a long time and not change and can make its root system produce rotten easily, so all need circulate in order to guarantee to the nutrition supply equilibrium of leaf lettuce growth usually, but traditional mode all is to irrigate nutrient solution after irrigating etc. nutrient solution and just irrigate once more, perhaps irrigate again a period of time apart, do not circulate the nutrient solution and supply, lead to leaf lettuce nutrient solution easily and draw inhomogeneously, the growing situation is different.
Disclosure of Invention
The invention aims to solve the problem that the nutrient solution of the leaf lettuce is not uniformly drawn due to the fact that the conventional nutrient solution irrigation is not circularly supplied.
In order to achieve the purpose, the temperature control device comprises a temperature control box, a controller, a rack arranged in the temperature control box, a liquid storage tank, a heating sleeve, an elastic air bag fixedly connected to the bottom of the liquid storage tank and positioned in the heating sleeve, a piston rod fixedly connected below the elastic air bag, a piston plate connected to the bottom of the piston rod and a liquid changing channel in sliding connection with the piston rod, wherein the liquid storage tank, the heating sleeve and the elastic air bag are all in sliding connection with the rack; the temperature control box is internally provided with a temperature sensor, the side wall and the top surface of the temperature control box are made of transparent glass, the side wall and the top surface of the temperature control box are both provided with a plurality of ventilation openings, the inner side wall of the temperature control box is connected with a breathing sponge layer, the side wall of the heating sleeve is provided with an air inlet, an air pipe is communicated between the air inlet and the air heater, the heating sleeve is internally provided with an air channel, the air channel divides the side wall of the heating sleeve into an inner wall and an outer wall, the inner wall is provided with a plurality of air outlets communicated with; the temperature sensor and the air heater are controlled by the controller, a culture dish is arranged on the rack on one side of the liquid storage tank, the liquid changing channel comprises three parts, namely a liquid pressing part, a liquid changing part and a connecting part, wherein the liquid pressing part is connected with the piston rod in a sliding mode, the liquid changing part is connected with the culture dish and communicated with the culture dish, the connecting part is connected between the liquid pressing part and the liquid changing part, the liquid pressing part and the liquid changing part are communicated through the connecting part, one side, close to the liquid changing part, of the connecting part is provided with a convex block protruding inwards, and a communicating pipe is.
