Abstract

The utility model discloses an auto-comtrol temp. plastic tunnel, comprising a plastic film, an inner tunnel frame, an inner tunnel plastic film, a plastic barrel, and water. The utility model is characterized in that water is conntained in the plastic barrel, and the plastic barrel is horizontally positioned on two sides of the vegetable sprouts and buried under a bed surface for 1/2 circular diameter. When the sun shines in the daytime, temperature rises in the inner tunnel, and the water automatically stores the heat, making the temperature in the inner tunnel not too high. When the temperature in the inner tunnel drops at night, the water automatically discharges the stored heat, making the temperature in the inner tunnel not too low. The utility model is good for enhancing the ground temperature, and the temperature in the inner tunnel can be controlled among the 15 DEG C-25 DEG C automatically in the day and night. The auto-comtrol temp. plastic tunnel is suitable for the vegetable growth in the inner tunnel.

Description

Auto-comtrol temp. plastic tunel

The utility model relates to the autocontrol temperature plastic tunnel, belongs to the greenhouse, more particularly is to be used for early maturity culture vegetables autocontrol temperature plastic tunnel.

The plastic tunnel of used early maturity culture vegetables because of temperature is low, is lighted stove in the canopy, underground energising heated filament improves the gentle temperature of shed in ground, consumes a large amount of energy, takes a lot of work, the expense height, even now, during because of daylight, temperature of shed sharply rises and reaches more than 30 ℃, and when not having illumination night, temperature of shed sharply drops to again about 7 ℃, temperature of shed drastic change among day and night, and the vegetables in the canopy can't grow, to the early stage supply in vegetables market, cause difficulty and cost an arm and a leg.

The purpose of this utility model is to provide a kind of can avoid above-mentioned weak point, only need investment in a small amount, do not take the energy and saving of labor, make the temperature at day night in the early maturity culture plastic vegetable greenhouse, automatic control is between 15 ℃～25 ℃, to be suitable for the growth of early stage vegetables, supply the market and the dish valency is reduced early.

For achieving the above object, the utility model autocontrol temperature plastic tunnel, form by plastic foil 1, frame 2, interior frame 3, interior canopy plastic foil 4, plastic barrel 6, water 7, be characterized in the plastic barrel 6, water 7 is housed places the both sides of dish seedling 5, and plastic barrel 1/2 garden of dress water directly is embedded under the furrow face, and the furrow face is directly exposed in 1/2 garden, and the canopy cover was encapsulated on the furrow face that buries the plastic barrel that water is housed in interior frame 3 was formed with interior canopy plastic foil 4.

The autocontrol temperature plastic tunnel, have when the illumination temperature of shed raises, automatically heat is stored in the water, does not make temperature of shed too high, when night temperature of shed cross when low, automatically the heat that will be stored in the water is released, do not make temperature of shed low excessively, can be with the temperature in the canopy, automatic control is between 15 ℃～25 ℃, be suitable for the growth of vegetables, alleviate the situation of early stage vegetables strained market supply and reduce price.

Accompanying drawing is the vertical cut-away view of autocontrol temperature plastic tunnel.

Accompanying drawing drawing explanation: frame, 4 interior canopy plastic foils, 5 dish seedlings, 6 plastic barrels, 7 water, 8 soils in 1 plastic foil, 2 frames, 3.

In order to implement preferably, it is as follows with the accompanying drawing to be that embodiment further specifies below:

Frame 2 adopts steel pipes or bamboo to become camber (degree of collapsing is determined as required), in dividing, in, outer three layers, 10cm inserts in ground at interval, and the continuity socket is to needs length.With the thick wide cut plastic foil 1 of 0.05mm, dividing three layers is fixed in respectively on the frame 2, form the long canopy of camber, the two ends of canopy are stayed one, surplus adds plastic foil sealing with the flat pattern frame, whole good furrow face, and (back of the body is built in order to administrative staff's walking in big ridge to tell big micro-ridge, micro-ridge is planted dish), 0.05mm is thick, φ 10cm plastic barrel 6 is got and canopy length together, fills water 7, again with the micro-ridge central longitudinal to and open two ditches, two plastic barrels that water is housed are kept flat and are embedded in the ditch, and make plastic barrel have radius to expose the furrow face, radius is embedded in the soil, and the both sides of burying two plastic barrels respectively stay the space of 20cm, trench digging respectively buries a plastic barrel of adorning water respectively again, and frame 3 in making of φ 6.5 reinforcing bars or bamboo bar makes it become camber 70cm, horizontal collapsing buried four plastic barrels adorning water, be solidly plugged in the furrow face, be arranged in order and insert canopy skeleton in solid the composition, place on the interior frame with the thick plastic foil 4 of 0.04mm, its both sides and two ends are sealed with soil pressure, canopy in forming.Use the same method and be covered with interior canopy in the canopy, during day on daytime illumination, when interior canopy temperature raises, the water that plastic barrel is adorned can store heat automatically, do not make temperature too high, and can very fast raising ground temperature, when nocturnal temperature hanged down, heat stored in the water was emitted automatically, and the temperature in not making in the canopy is low excessively, interior canopy Sino-Japan night temp autocontrolled between 15 ℃～25 ℃, after local temperature rise rises, one side with the space that the dish transplantation of seedlings is stayed in interior canopy of rolling of interior canopy plastic foil 4, press seal is put down on the limit of the interior canopy plastic foil 4 that will roll again, the dish seedling can delay the seedling growth, and the nervous situation that can alleviate early stage vegetables market supply early also can reduce the price of dish.

Claims

1, autocontrol temperature plastic tunnel is made up of plastic foil 1, frame 2, interior frame 3, interior canopy plastic foil 4, plastic barrel 6, water 7, it is characterized in that in the plastic barrel 6, water 7 is housed is flat on dish seedling both sides and is embedded in footpath, 1/2 garden under the furrow face.

2, by the described autocontrol temperature plastic tunnel of claim 1, it is characterized in that said in the interior canopy formed of frame 3 and interior canopy plastic foil 4, cover is enclosed on the furrow face of putting the plastic barrel 6 that buries dress water 7 and dish seedling.
