However, because the existing greenhouses cannot meet the growth needs of eggplants by relying on sunlight alone, and the cost of auxiliary heating is too high, the desire to grow eggplants all year round in areas north of 43° north latitude has not been realized.

Embodiment Construction
[0014] figure 1 , 2 A winter eggplant solar greenhouse in the area north of 43° north latitude is introduced, which consists of a shed surface 1, a shed frame 2, a column 3, a beam 4, a pole 5, a shed cover 6, an insulation quilt 7, and an insulation wall 8. The thermal insulation wall 8 of this solar greenhouse is made of piles of soil, the width at the bottom of the wall is d=4000mm, and the upper and lower deviations are less than 100mm, which is between 3900-4100mm. The width on the wall is 2500mm, and the upper and lower deviation is less than 50mm, between 2450-2550mm. The inner height of the wall is f=1700mm, and the upper and lower deviation is less than 50mm, which is between 1650-1750mm. The span inside the shed is b+c=5500mm, and the up and down deviation is less than 100mm, between 5400-5600mm. The distance between the column and the inner side of the insulation wall is c=1100mm, and the upper and lower deviation is less than 20mm, which is between 1080-1120mm. ...

Abstract
The invention relates to an agricultural facility, in particular to an eggplant solar greenhouse growing in an area north of northern latitude 43 degrees in winter. The eggplant solar greenhouse comprises a shed surface (1), a shed frame (2), upright posts (3), cross beams (4), a shed cover (6), a heat-insulating blanket (7) and a heat-insulating wall (8). The eggplant solar greenhouse is characterized in that: for the heat-insulating wall (8) of the solar greenhouse, the bottom width d is 3,900-4,100mm, the upper width g is 2,450-2,550mm and the inside height f is 1,650-1,750mm; the span inside the shed b plus c is 5,400-5,600mm, the distance c between the upright posts (3) and the inside of the heat-insulating wall (8) is 1,080-1,120mm, the cross beams (4) are supported on the upright posts (3) and the total height e of the upright posts (3) and the cross beams (4) is 2,650-2,750mm; and the shed cover (6) is supported on the cross beams (4); and the inside elevation gamma of the shed cover (6) is 41-42 degrees. Compared with the traditional solar greenhouse, structural parameters of the invention have large change, so that the invention remarkably improves the light-acceptance performance and the heat-insulating capability of the greenhouse, provides adequate conditions for the growth of solanaceous fruit vegetables, in particular eggplants, achieves the goal of continuously producing the eggplants all year round by only depending on sunlight heat source in the area north of northern latitude 43 degrees in winter and remarkably improves the economic benefits.
Description
technical field [0001] The invention relates to an agricultural facility, that is, an eggplant solar greenhouse in winter in the area north of 43° north latitude. Background technique [0002] A solar greenhouse, also called a plastic vegetable greenhouse, is an agricultural facility for growing vegetables in cold seasons. Solar greenhouses are mostly composed of shed surfaces, shed frames, shed covers, insulation walls, and insulation quilts. The size of each part is designed according to the angle of altitude, latitude and sunshine, in order to obtain optimized light receiving conditions. In areas north of 43° north latitude, the temperature in winter is generally between -20-25°C, and vegetable production can only be carried out in greenhouses. At present, the solar greenhouse that is widely used here is the 43-type solar greenhouse. Its main parameters are: the bottom width of the insulation wall is 1.8m, the top width is 1.6m, and the inner wall height is 2.2m. It is ...
