The utility model has the advantages of less investment, simple management and quick and robust seedling growth. The utility model is suitable for the small area seedling raising in a peasant family and is also suitable for the industrial seedling raising. According to the test, the utility model has the ideal effects to enhance the vegetable seedling, the tobacco seedling and the paddy rice seedling.

Description

Vegetable cultivating forcing-frame with low temp. and hot-water trough

The utility model relates to a kind of raise seedling in hot bed equipment.

It is the method for quickly breeding thermophilic vegetable in more welcome early spring (or crop) seedling at present that electric seed bed heater is grown seedlings, though this technology has its characteristics, such as convenient management, nursery effect etc., because it is to utilize electric heating to improve soil temperature, thereby it to take electricity bigger, the equipment input is also high; On the other hand, in 1-3 month in early spring, on the occasion of buying the water phase, electric power also is difficult to guarantee again.Moreover electric seed bed heater does not have heat-preserving equipment, and after the power failure, bed temperature is just reduced to conventional ground temperature, so damage to plants caused by sudden drop in temperature sometimes.

The purpose of this utility model provides a kind of warm water of utilization and facilitates the seedling nursing device of educating bed tempertaure.

Above-mentioned purpose is achieved in that and the utlity model has shed, cultivates soil layer and can be covered in the mulch film of cultivating the soil layer surface, have the carriage mechanism of band pore at the cultivation soil layer, cultivate soil layer so that hold up, below cultivating soil layer, be provided with tank, fill warm water in the tank, cultivating soil can absorb from warm water, the heat that gives out, thus keep growing seedlings required soil temperature and humidity; Be filled with the lower adiabator layer of thermal conductivity factor below around tank, reaching, reduce the invalid of warm water heat and scatter and disappear, keep water temperature, more can be for a long time to cultivating the soil layer heat supply.

The carriage mechanism of above-mentioned band pore is by the support of grillage, supporting grillage and place the narrow meshed plastic sheeting for farm use above the grillage to form, cultivates soil layer and places on the narrow meshed plastic sheeting for farm use, because the support effect of grillage, cultivation soil can not fall down.

On the outer surface of above-mentioned adiabator layer, be coated with plastic sheeting for farm use,, can strengthen heat insulation effect because the thermal conductivity factor of plastic sheeting for farm use is very little.

Be mixed with the rice husk material of the pine effect of making in the above-mentioned cultivation soil layer, also kept cultivating and has more air chamber to exist in the soil layer, be convenient to heat energy and be able to the long period storage and stay.

The utility model also can be provided with the leg means that can play the support effect to whole adiabator layer, cultivation soil layer carriage mechanism below adiabator layer, this leg means can be by placing supporting plate and corresponding supporting leg below the adiabator layer to constitute, move supporting leg, promptly realize moving of the whole bed of growing seedlings.

The utility model provides the bed of growing seedlings a kind of brand-new early spring, it is compared with existing electric seed bed heater, has advantages such as reduced investment, simple and convenient management, its cost have only that electric heating grows seedlings 1/10, whole nursery stage also no longer need water, and equipment and materials can also use repeatedly for many years.More valuable is that the utility model can make full use of the industrial waste water of different temperatures, particularly can directly utilize 35-40 ℃ low temperature waste heat water, thereby the seedling cost can be lower.The utility model changed water if adopt at 8 o'clock in the morning, can reach thermophilic 25-30 ℃ scope at 9 o'clock, cooling is just obvious after at 5 o'clock in afternoon, this alternating temperature process can be synchronous with illumination, adapt to fully and when satisfying vegetable seedling and carrying out photosynthesis daytime to the needs of temperature, evening, lower temperature can suppress crop breathing use again, reduce nutrient consumption, the thermoperiod rule that meets crop, the favorable environment and the condition in bed can create effectively that ground temperature is higher, temperature is on the low side so originally grow seedlings cultivation vegetables in early spring (or crop) strong sprouts, the seedling stalwartness of cultivating, growth are rapidly.The utility model is fit to peasant household's small size grows seedlings, and is more suitable for factorial seedling growth.

Further specify the utility model below in conjunction with drawings and Examples.

Embodiment 1

The low-temperature water heating groove of the present embodiment bed of growing seedlings places the soil box (see figure 1), it has little shed 1, cultivates soil layer 2, cultivate and to mix 1/3 the sterilization rice husk (by volume) of having an appointment in the soil layer 2, be rarefaction so that keep cultivating soil, and a large amount of air chambers storage heat energy are arranged in the soil; Have carriage mechanism 3 with the whole cultivation soil layer of support at the cultivation soil layer, carriage mechanism 3 is by the grillage of being made by bamboo matter 4, support 5 and place the narrow meshed plastic sheeting for farm uses 6 above the grillage 4 to form, under cultivating soil layer 2, be provided with tank 7, tank 7 is formed by plastic sheeting for farm use 8 grooving, fill water temperature in the tank 35--75 ℃ warm water 9, below reaching around the tank 7, be filled with by rice husk, the adiabator layer 10 that the straw class constitutes, adiabator layer 10 outer surfaces are coated with plastic sheeting for farm use 11, because agricultural film, the thermal conductivity factor of rice husk is far below soil, so stoped the hot water heat to conduct downwards and all around, again because of sealing, prevented gaseous exchange, so sink structure good heat preservation performance of the present utility model, the spongiosa that heat energy is directly supplied to be added with rice husk is cultivated in the soil, and can be stranded in the soil long period, can also keep the humidity in the soil simultaneously automatically.Around cultivating soil layer 2, be filled with the insulation material 12 that constitutes by straw equally, its outer plastic sheeting for farm use 13 that is coated with; Side at tank 7 has floss hole (not shown), is convenient to change water.14 is mulch film among Fig. 1, is covered in to cultivate the soil layer surface; 15 is big arch shed.

Embodiment 2

The bed of growing seedlings of present embodiment places on the ground for the packaged type bed of growing seedlings.It has as present embodiment 1 all architectural features described in the bed of growing seedlings; different is; present embodiment is provided with the leg means that whole adiabator layer 10 is played the support effect below adiabator layer 10; this leg means is by placing supporting plate 16, pallet supporting leg 17 below the adiabator layer to constitute (see figure 2); on the lateral margin of supporting plate, also be provided with the baffle plate 18 of protection plastic sheeting for farm use 11; during use, move leg means, promptly realize moving of the whole bed of growing seedlings.
