Description

Stereo constant temperature seedling box

technical field

The utility model relates to a seedling-raising greenhouse, in particular to a three-dimensional constant-temperature seedling-raising box, which belongs to the technical field of modern agriculture.

Background technique

Greenhouses use the sun's radiant light to maintain the temperature and humidity in closed greenhouses for vegetable cultivation. It is one of the trends in modern high-efficiency agricultural planting and has achieved certain results. However, the current greenhouse basically relies on the natural light energy of the sun for heating. However, due to the continuous change of the intensity of sunlight with the weather, the temperature in the greenhouse cannot be kept within an effective range, causing serious damage to the normal growth of crops in the greenhouse. Certain impacts and even hazards, especially the slow growth of vegetable seedlings, the carbon dioxide required for photosynthesis of vegetables in greenhouses cannot be fully supplied; resulting in slow emergence of vegetables and irregular growth, seriously affecting the quality of vegetables throughout the growth period.

Utility model content

The purpose of this utility model is to overcome the defects existing in the current greenhouses, and provide a method that can replace the vegetable seedling stage of the greenhouse, is not affected by the season, can adjust the carbon dioxide, illuminance and temperature required for the photosynthesis of vegetable seedlings, and has the advantages of fast emergence, growth A three-dimensional constant temperature seedling box for neat and strong seedlings. The three-dimensional constant temperature seedling box also has wide versatility and convenient mobility.

The technical scheme of the utility model is achieved as follows: a three-dimensional constant temperature seedling cultivation box, including a box body constructed of thermal insulation boards, a movable three-dimensional seedling cultivation frame located in the box body, carbon dioxide gas production equipment and a constant temperature heating device. The body is in a sealed state, with a box door on the side, supporting feet on the bottom, and a suspension ring on the top; the carbon dioxide gas production equipment and the constant temperature heating device are independently installed on the outer side of the box, and are passed through the gas supply pipeline and the heating pipeline respectively. And the automatic control system is connected with the box; the movable three-dimensional seedling frame is placed in the box, and each movable three-dimensional seedling frame is provided with multi-layer nutrient solution tanks or pools; wherein each layer of nutrient solution tanks or pools There is a lighting or supplementary light source mechanism on the top, and there are seedling trays arranged in parallel floating in the nutrient solution tank or pool; there are air circulation fans, temperature sensors and carbon dioxide gas concentration sensors in the box space; the temperature sensor and carbon dioxide gas concentration sensor Connect to automatic control system.

Compared with the prior art: the utility model adopts lighting or supplementary light source mechanism, carbon dioxide gas production equipment and constant temperature heating device, uses temperature sensor and carbon dioxide gas concentration feedback information, and is automatically adjusted by the automatic control device to make the carbon dioxide in the seedling box Concentration, illuminance and temperature are finally kept within the environmental range required for vegetable seedling cultivation. The utility model has good thermal insulation and temperature regulation performance, good photosynthesis effect, and neat seedling emergence; it is an ideal three-dimensional constant temperature seedling cultivation box. In addition, the appearance of the utility model can be moved as a whole, and can be used in conjunction with the greenhouse; that is, after the vegetable seedling period is realized by the utility model, it is transplanted into the greenhouse, and the vegetable growth period and maturity period are completed in the greenhouse. After production, the time is alternately staggered, so that vegetables in the greenhouse only have two periods of growth and maturity, which is equivalent to saving one month of growth for the entire greenhouse vegetables.

Detailed ways

Below in conjunction with accompanying drawing and specific embodiment, the utility model is described in further detail:

As shown in Figure 1-2, a three-dimensional constant temperature seedling cultivation box includes a box body (1) constructed of thermal insulation boards, a movable three-dimensional seedling raising frame (2) located in the box body (1), and carbon dioxide gas production equipment (3 ) and a constant temperature heating device, the box (1) is in a sealed state, with a door (4) on the side for the operator to enter and exit, a support foot (5) on the bottom, and a lifting ring for mobile lifting on the top ( 6); the carbon dioxide gas production equipment (3) and the constant temperature heating device are independently installed on the outer side of the box (1), respectively through the gas supply pipeline (7), the heat supply pipeline (8) and the automatic control system and the box The carbon dioxide gas production equipment (3) is a barrel body, and a cylindrical inner cup is fixed by a cover in the barrel. There is a through hole at the bottom of the inner cup, and the upper opening of the inner cup is sealed by the cover. A groove is arranged on the side wall of the inner cup, and a through hole leading to the cup is arranged at the upper end of the groove, and a U-shaped pipe with a downward bending upper end is inserted in the hole. When in use, fill the bucket with dilute sulfuric acid, fill the inner cup with ammonium bicarbonate, put the lid on the bucket and the inner cup to seal, and the reaction gas carbon dioxide is discharged from the gas outlet. A plurality of movable three-dimensional seedling raising frames (2) are placed in the box body (1), and each movable three-dimensional seedling raising frame (2) is provided with multi-layer nutrient solution tanks or pools (9); wherein each layer of nutrient solution A lighting or supplementary light source mechanism (10) is arranged above the tank or pool (9), and there are seedling trays (11) arranged in parallel floating in the nutrient solution tank or pool (9); inside the seedling tray (11) there are neatly arranged Cup-shaped hole filled with nutrient soil. The air circulation fan, temperature sensor and carbon dioxide gas concentration sensor are arranged in the space of the box body (1); the temperature sensor and the carbon dioxide gas concentration sensor are connected to the automatic control system. This embodiment is used in conjunction with the greenhouse; that is, after the vegetable seedling period is realized by the utility model, it is transplanted into the greenhouse, and the vegetable growth period and the maturity period are completed in the greenhouse. After mass production, the time is alternately staggered, so that in the greenhouse Vegetables in the greenhouse only have two periods of growth and maturity, which is equivalent to saving one month of growth for the entire greenhouse vegetables.
