Introduction:

Vegetable greenhouses usually refers to the solarium, for the planted vegetable greenhouses know that there is a back wall, in the relevant solarium design specifications require between 2-2.5 meters, this design is more conducive to heat preservation, ventilation and heat dissipation. In the actual construction of the height of the crops planted according to the user to determine the height of the space in the shed.

Introduction:

The people who can have such a question, that itself has not been engaged in agricultural production activities or people from other planets. Normally normal adults or say people who are capable of working would be much taller than a meter. Do you ask people to work, but also crawling to work? Obviously it is impossible thing. Vegetable greenhouses are generally planted in the winter is also called anti-seasonal planting, on the greenhouse night insulation requirements are very high, but also ventilation during the day to dissipate heat, to ensure that the fresh air in the greenhouse, to be more conducive to the growth of vegetable greenhouses. A meter high shed can not play any role, at best, the family in the Spring Festival when the use of the kind of simple small film covered shed, in northern China in March-April with the general, mainly to increase the low temperature, usually in a month after the withdrawal, is not considered to be a vegetable greenhouse.

The solar greenhouse south along the bottom foot to the north wall root distance. Span large land utilization rate is high, but not easy to heat preservation; span small easy to heat preservation, land utilization rate is low. General span of 8, 10, 12 meters. Latitude south of the span can be larger, north of the region smaller.

Vegetable greenhouse construction should first ensure that the land leveling, electricity, water, roads and other infrastructure, the basic design of the greenhouse contains greenhouse span, height, slope of the light surface, the height and thickness of the back wall.

The height of the greenhouse is the vertical distance from the ridge to the ground. After the span is determined, the ridge is high, the light roof angle is large, favorable lighting; but too high, unfavorable heat preservation, inconvenient ventilation, generally 3 meters for more. Daylight greenhouse lighting roof slope 23 ° ~

25 ° C is the best, which is commonly used in northern China angle range.

Nowadays, the back wall of most solar greenhouses is a brick wall of 24 centimeters plus 10 centimeters of insulation, with polystyrene boards acting as part of the insulation wall. The height of the rear wall is generally a minimum of 2-2.5 meters can be, but there are special circumstances, that is, in the solar greenhouse planting of fruit trees in the class of the need to raise the height of the rear wall, more than enough space to meet.

Summary:

Vegetable greenhouse internal height to do 2.5-3 meters, more suitable for vegetables is the need to grow, there is enough fresh air. There are also personnel inside planting operations, but also more convenient, in line with human physiology structural science.

Summary:
