Embodiment 1

[0022] figure 1 with figure 2 It is the circular multifunctional greenhouse described in Example 1. The greenhouse includes a greenhouse body 4, and the greenhouse body 4 is divided into upper and lower layers. The upper greenhouse includes a back wall and a film support. The bottom end of the back wall is fixed on the lower greenhouse, and the top is connected with a film support. The other end of the film support extends to the front of the back wall and is fixed on the lower greenhouse. The lighting surface of the bracket is covered with a transparent plastic film, and steel brackets are provided on both sides of the back wall, and the angle between the back wall and the horizontal direction is not less than 15°. By setting a certain included angle, the area of ​​the shaded area behind the back wall under sunlight can be reduced, thereby reducing the distance between rows of greenhouses and making full use of the planting land. Since the angle of sunlight irradiation in...

Embodiment 2

[0027] image 3 It is the circulation multifunctional greenhouse described in embodiment 2. The difference from Embodiment 1 is that the heat pump in this embodiment only includes the air source heat pump 3 , and the air source heat pump 3 is fixed on the top of the greenhouse body 4 .

[0028] Others are with embodiment 1.

Embodiment 3

[0030] Figure 4 It is the circulation multifunctional greenhouse described in embodiment 3. The difference from Embodiment 1 is that the heat pump in this embodiment only includes the water source heat pump 11, and the water source heat pump 11 is fixed in the greenhouse.

[0031] Others are with embodiment 1.

Abstract

The invention relates to a greenhouse planting technology, in particular to a circulation multifunctional greenhouse which comprises a greenhouse body, wherein the greenhouse body is internally provided with a heat pump; the soil under the greenhouse body is internally provided with a methane pond and a reservoir; the methane pond is internally provided with a methane tank and a hot water coil pipe wound outside the methane tank; an insulating layer is filled outside the methane tank; the reservoir is internally provided with a heat accumulation water tank which is externally provided with an insulating layer; the heat accumulation water tank is provided with three sets of circulating water pipes, wherein the first set of circulating pipe is connected with a cooling device arranged in the greenhouse; a water inlet of the second set of circulating pipe is communicated with a water outlet of the heat pump, and a water outlet of the second set of circulating pipe is communicated with a water inlet of the heat pump; a water inlet of the third set of circulating pipe is communicated with a water outlet of the hot water coil pipe, and a water outlet of the third set of circulating pipe is communicated with a water inlet of the hot water coil pipe; a gas outlet of the methane tank is connected with a methane lamp which is fixed in the greenhouse; and the top of the greenhouse body is provided with a light supplement lamp.

Description

technical field [0001] The invention relates to a greenhouse planting technology, in particular to a circular multifunctional greenhouse. Background technique [0002] At present, in many areas of our country, various vegetables are cultivated in greenhouses, and greenhouse cultivation has become an important part of modern agriculture. In order to enable the normal growth of crops, the temperature in the greenhouse should preferably be kept within 25-30°C. However, in the actual planting process, due to the closed structure of agricultural settings such as solar greenhouse plastic greenhouses, the water vapor generated by soil evaporation and plant transpiration inside is limited in a limited space, which will increase the air humidity in the greenhouse. increase, and cause the temperature in the greenhouse to be too high. Especially in summer, maintaining excessively high temperature and air humidity for a long time will not only damage the plants, but also easily induce...
