Abstract

The utility model discloses a constant temperature floating nursery pond which comprises a water pond (1), a thermal insulation cushion (2) and a base film (3). The thermal insulation cushion (2) is arranged at the bottom of the water pond (1). The base film (3) is arranged at the bottom and the circumference of the water pond (1). A reflective thermal insulation film (6) is arranged on the thermal insulation cushion (2). Heating cables (7) are evenly distributed between the reflective thermal insulation film (6) and the base film (3). In time of raising seedlings, nutrition liquid (4) is put in the nursery pond. A temperature controller and a temperature probe are installed, a seedling raising tray (5) floats on the nutrition liquid (4) of the nursery pond, sprouting, growing, developing and other processes of tobacco seedlings are finished, the tobacco is transplanted to a large field for growth. The nutrition liquid (4) can be evenly heated, heat is reflected by the reflective thermal insulation film at the bottom of the nursery pond to the nutrition liquid in the nursery pond and a constant temperature heating system of the floating nursery pond is high in energy utilization rate, low in energy consumption and particularly suitable for nursing tobacco seedlings.

Description

A kind of constant temperature Flotage seedling raising pool
Technical field
The utility model relates to a kind of seedling nursing device of tobacco leaf seedling, particularly a kind of constant temperature Flotage seedling raising pool.
Background technology
Along with the continuous progress of tobacco leaf seedling technology, nursery pond is also constantly updated thereupon and is regenerated.Growing seedlings of existing tobacco leaf seedling generally all is to adopt Flotage seedling raising pool to grow seedlings, and belongs to soilless culture, and Flotage seedling raising pool forms (as shown in Figure 1) by pond 1, heat keeper 2 and basement membrane 3, and heat keeper 2 is positioned at 1 bottom, pond, and basement membrane 3 is positioned at the bottom in pond 1 and all around.When growing seedlings, nutrient solution 4 is put into nursery pond, will grow seedlings again and float on dish 5 nutrient solutions 4 that float in the nursery pond, finish the processes such as rudiment, growth, growth of tobacco leaf seedling, and then be transplanted to field planting.Because some region winter temperatures differ larger, and the reduction of temperature can cause poor growth even the death of seedling, therefore need to the water temperature of nursery pond be controlled, make water temperature be unlikely to too low.What generally adopt at present is following several mode:
1, indoor heating: by heater the air of nursery pond is heated, thereby reach the purpose of temperature, this mode efficient of heating is low, substantially is not used.
2, soil is heated: heat by the ground under water to nursery pond, thereby indirectly water temperature is controlled, the relatively indoor heating mode of this soil heating mode, capacity usage ratio improves a lot, but owing to adopting indirect temperature adjustment, heat energy has been diffused away greatly, can not carry out maximum utilization to energy.
3, water directly heats: the direct heating water of heat energy, and energy loss is little, and the also employing thermoregulator that has automatically adjusts to temperature, the shortcoming of this mode is that water temp. heating is inhomogeneous, water temperature is high near the heater, and is low away from the water temperature of heater, and the availability of heat energy is still not high.
Summary of the invention
The purpose of this utility model is the above-mentioned deficiency that overcomes prior art, and a kind of temperature of fry nursing pool homogeneous heating that can make is provided, and the constant temperature Flotage seedling raising pool that the availability of heat energy is high, power consumption is few.
The technical solution of the utility model is: a kind of constant temperature Flotage seedling raising pool, be comprised of pond, heat keeper and basement membrane, heat keeper is positioned at basin bottom, and basement membrane is positioned at the bottom in pond and all around, on heat keeper, also have the reflective thermal-insulating film, between reflective thermal-insulating film and basement membrane, be evenly equipped with heating cable.
The further technical scheme of the utility model is: heat keeper adopts thickness greater than 30mm, and density is greater than 20KG/m 3Polyphenylene heat insulation slab.
The utility model further technical scheme is: heating cable adopts the heat accumulating type heating cable.
The utility model is owing to adopting as above design, nutrient solution in the nursery pond can access uniform heating, heat reflects nutrient solution to nursery pond by the reflective thermal-insulating film that is arranged in nursery pond bottom, the energy utilization efficiency of Flotage seedling raising pool constant temperature heating system is high, power consumption is few, is particularly suitable for growing seedlings of tobacco leaf seedling.
Below in conjunction with the drawings and specific embodiments detailed content of the present utility model is further described.
Description of drawings
Fig. 1 is the structural representation of existing Flotage seedling raising pool;
Fig. 2 is structural representation of the present utility model.
Embodiment
As shown in Figure 2: a kind of constant temperature Flotage seedling raising pool, be comprised of pond 1, heat keeper 2 and basement membrane 3, heat keeper 2 is positioned at 1 bottom, pond, and basement membrane 3 is positioned at the bottom in pond 1 and all around, on heat keeper 2, also have reflective thermal-insulating film 6, between reflective thermal-insulating film 6 and basement membrane 3, be evenly equipped with heating cable 7.Heat keeper 2 adopts thickness greater than 30mm, and density is greater than 20KG/m 3Polyphenylene heat insulation slab; Basement membrane 3 is plastic film, and its effect is to prevent oozing out of pond 1 interior nutrient solution 4, and pond 1 outer water penetrates in the pond 1; Heating cable 7 adopts the heat accumulating type heating cable.
Using method of the present utility model and operating process are: when growing seedlings, nutrient solution 4 is put into the utility model nursery pond, install temperature controller and temp probe, to grow seedlings again and float on dish 5 nutrient solutions 4 that float in the utility model nursery pond, finish the process such as rudiment, growth, growth of tobacco leaf seedling, and then be transplanted to field planting.

Claims (3)
