Embodiment 1

[0071]Multifunctional double-layer film solar greenhouse suitable for cold regions, such as Figure 1-7 As shown, it includes a first wall 1, a support plate 2, a vertical truss 3, an oblique truss 4, an arch 5, an outer non-drip film 6, an inner non-drip film 7, an electric film roll 8, and a thermal insulation quilt 9. The second wall 10, the color steel sandwich panel 11, the first end wall 12, the first rolling door 13, the second end wall 14, the second rolling door 15, the third rolling door 16, the window 17, the door 18, Exhaust fan 19, planting area 20, multi-functional area 21, and rain cover 22, wherein the first wall body 1 extends along the east and west directions, the support plate 2 is vertically fixed on the top of the first wall body 1, and the vertical truss 3 is located at the second On the south side of a body of wall 1, one end of the diagonal truss 4 is connected to the top of the vertical truss 3, and the other end of the diagonal truss 4 is connected t...

Embodiment 2

[0089] This embodiment is used to investigate the thermal insulation effect of the greenhouse provided in Example 1 in the winter environment in cold regions:

[0090] Test site: Huanzidong Village, Gongzhuling City, Jilin Province, 43°31′23.69″N, 124°47′42.99″E. An ordinary solar greenhouse in Huanzidong Village, Gongzhuling was selected as a control.

[0091] Test method: From November 1, 2017 to March 20, 2018, record the outdoor temperature, the ground temperature of the control greenhouse and the test greenhouse at 6:30 every morning.

[0092] Ground temperature measurement: measure the temperature at a depth of 15 cm in the soil bed of the greenhouse with a thermometer.

[0093] Experimental results: if Figure 8-9 As shown, the solar greenhouse of the present invention can significantly increase the ground temperature inside the greenhouse, and the average temperature in winter is 14.9°C, which is 28.2°C higher than the average outdoor temperature, and the average tem...

Embodiment 3

[0095] This embodiment aims to use the greenhouse provided in embodiment 1 to implement the combination of chicken and fruit and vegetable cultivation and the recycling of straw litter.

[0096] 1. Materials and Methods

[0097] 1.1 Test materials

[0098] The eggplant variety is Longzaqie No. 5.

[0099] The breed of chicken is reed chicken.

[0100] 1.2 Test location

[0101] The experiment was carried out from September 2017 to March 2018 in the double-layer film solar greenhouse (N43°31′8″, E124°47′2″) of Gongzhuling Campus, Jilin Academy of Agricultural Sciences.

[0102] 1.3 Test method

[0103] Two sheds were selected for the test, and the cultivation area of ​​the test shed was planted 134m 2 , multifunctional area per m 2 8 reed chickens were raised, and a total of 1280 were raised. The control greenhouse only planted 134m in the planting area 2 . A 15cm thick corn stalk bedding is spread on the ground of the multi-functional area to absorb chicken excrement ...

Abstract

The invention provides a multifunctional two-layer membrane solar greenhouse suitable for being used in a cold region and a using method thereof. According to the technical scheme, the upper and lowersides of a lagging jack are covered with double-layer non-drip anti-aging film, and the film is fixed on the surrounding wall body and a south side foundation through clamping springs to form an insulating structure similar to 'hollow glass'; a polyphenyl plate is additionally arranged downward on the periphery of a basic structure to significantly reduce the greenhouse through-flow heat generation and soil transverse heat transfer; the top of the greenhouse is additionally provided with a rain shed to reduce the erosion of the environment to an insulating layer and prolong the service life of the insulating layer. On this basis, a multi-functional area is additionally arranged on the north side of a main structure of the greenhouse and cooperates with a planting area in the greenhouse tomake full use of resources such as land resources, bio-heat resources and the like to further improve the greenhouse temperature in autumn and winter and the overall economic benefits. Based on the structural characteristics of the greenhouse, a method for combining cultivation of fruits and vegetables with poultry and a mixed cultivation method of fruits and vegetables and edible fungi are further developed, thereby realizing the complementary advantages of planting and breeding.

Description

technical field [0001] The invention relates to the technical field of facility agriculture, in particular to a multifunctional double-film solar greenhouse suitable for cold regions and a method for using the same. Background technique [0002] Facility agriculture is a facility project that uses artificial technology to change natural light and temperature conditions, create environmental factors that optimize the growth of animals and plants, and enable them to grow around the clock. With the continuous development of facility agriculture, the time and geographical scope of crop cultivation have been significantly expanded. Taking the protected vegetable industry in Jilin Province as an example, by the end of 2017, the area of ​​protected vegetables in the province had reached 1.2 million mu, accounting for 18.3% of the province’s vegetable field area, with an output of about 4 million tons, providing employment for more than 500,000 farmers, and creating output value Ab...
