Medical Planting Agricultural Greenhouse With Blackout Curtain
The history of greenhouse development
Israel, which has limited arable land and extremely low rainfall, is the pioneer of greenhouses. As early as the 1970s, due to the limitations of the country’s natural resources, Israel also relied heavily on imports for agricultural products. After that, Israel adjusted its crop planting structure, reduced the planting of food crops that required high land resources, and actively developed greenhouses. Technology, the planting of flowers, vegetables and fruits with high output value has greatly improved the situation of agricultural production. Since the 1970s, Israel’s greenhouse technology has realized intelligence and automation. A greenhouse is about 4000 square meters. The whole process from planting to harvesting is controlled by computer. Basically, no manpower is required. Moreover, drip irrigation technology is introduced into the greenhouse system. Increased the output of flowers, vegetables and other crops.
Through the vigorous development of efficient and intensive modern facility gardening, Israel has created a miracle of desert agriculture: agricultural output has increased by 12 times, agricultural water consumption has only increased by 3 times, land output value per unit area has tripled, and water output value per unit has increased 5 times. The number of support for a full-time agricultural worker rose from 17 to 113. On this basis, through the use of intelligent water and fertilizer integration, recycling water and other facilities gardening technology measures, not only can save about 30%-40% of water and chemical fertilizers than ordinary facility planting, but also the precision fertilization of micro-drip irrigation also makes the yield of agricultural products significant. Promote. The yields of cotton, citrus, and tomatoes in facility gardening are all top in the world. It is said that the yield of tomatoes per unit is nearly 10 times that of the facilities planted in our country.
Market momentum to promote the development of greenhouses
With the improvement of living standards, consumers in the city all like to eat off-season dishes, and they are willing to enjoy the treatment of their favorite dishes throughout the year. The traditional supply of melons, fruits and vegetables is planted and harvested according to the season, just like flooding during the flood season. It will not come until the flood season. In the past, in the north, in the cold winter, the outdoor temperature was very low and vegetables could not grow. There are only radishes and cabbage in the fields, besides, all the people can eat are potatoes. Summer vegetables such as tomatoes, cucumbers, and eggplants cannot grow.
