The greenhouse is also called the warm room.It can transmit light, heat preservation (or warm) to cultivate plants facilities.In the seasons that are not suitable for plant growth, you can provide greenhouse fertility and increase yield. It is mostly used for plant cultivation or seedlings such as vegetables, flowers, forests and other plants in low temperature seasons.There are many types of greenhouses, and they can be divided into many types according to different roof materials, lighting materials, shape and heating conditions.
Greenhouse greenhouse principle
The greenhouse is an agricultural building facility that uses light transmittance materials as all or part of the surrounding structure. It has a certain environmental regulation equipment that is used to ensure that crops can grow and develop normally and developing normally.The function of the greenhouse is to create environmental conditions suitable for crop growth and development under the adversity of the natural environment and perform effective production.The solar radiation based on short -wave radiation enters the greenhouse through the greenhouse lighting material to increase the mild temperature of the indoor in the indoor radiation, and the long wave radiation is blocked by the greenhouse materials in the greenhouse, thereby forming the accumulation of indoor calories, making the indoor temperature indoor temperatureImprove, this process is called "greenhouse effect".
Greenhouse greenhouse size
The greenhouse is about 10 meters long and 5 or 6 meters wide.The width of the greenhouse is similar, and the length is much longer.Some more than 100 meters.
What to make money for greenhouses
1. Tulip incense flowers.The seed ball is about 3 pieces, a greenhouse is planted 13000 --15,000, and it can be sold for 10-16 yuan.2. Multi -meat.There are many types and different prices, but the difference can also be 20-40 yuan.3. Vegetables and vegetables.Such as strawberries, after the greenhouse, there are sales in all seasons.Consumer goods, turn around quickly.
Greenhouse greenhouse cost
1. The greenhouse such as sunlight greenhouse is very good. It can make efficient anti -seasonal vegetable production or crop cultivation in the cold winter in the north, so it is also very popular.The good thermal insulation performance and practicality of the sunlight greenhouse benefited from its thick wall structure. The walls are generally soil. We usually cover a layer of non -woven fabric on the outside of the wall, and then spray cement mortar.It looks more beautiful.The standard sunlight greenhouse is generally about 100 meters in length, and the internal front and rear span is generally 10 meters. Excluding the wall part of the solar greenhouse greenhouse, the front room is now mostly structured, sturdy and reliable, covered with anti -flow, anti -aging aging, anti -aging aging, and anti -aging aging.The PO film and quilts for greenhouses are plus a roller.Such a sun-light greenhouse cost is less than 100,000, and the charter of the contract is 40,000 to 50,000.If the configuration is appropriately reduced, the cost of this greenhouse can be lower, about 40,000 per acre of land.Due to the needs of use, the internal and rear spans of this sunlight greenhouse can also be made into 8 meters, 9 meters, 11 meters, 12 meters, or larger. The cost of one acre will be different but not large.
