Under Dongjiaoshan Mountain, 20 kilometers away from Wuxi City, Jiangsu Province, an ecological product group integrating production, living and ecological functions, gourmet food, leisure, sightseeing, amusement and science education - Wuxi City Venture Park has injected new vitality into the city: Modern Agricultural Expo Park has become a famous agricultural experience park near and far; high-tech agricultural demonstration park allows people to experience the charm of modern agriculture such as soil-less cultivation and drip irrigation cultivation; in the demonstration area of high-quality rice production, the scale of special agriculture such as pollution-free rice, vegetables and aquatic products has been growing; the demonstration area of famous flower production and green mountains and water make people linger for a long time.
What is surprising is that this was once a quarry for building stones that had been mined for more than 30 years. In 2008, the Wuxi Municipal Bureau of Land and Resources decided to close the quarry and restore it to the local flora. Ecological environment.
"This is to plant trees on the bald rocks!" This was difficult for many companies specializing in environmental restoration business. On the unexcavated half of the mountain, there are not only grasses and shrubs, but also tall trees such as balsam fir, maidenhair, beech and acacia. The slope of the bald rock, on the other hand, is 60 to 90 degrees, with a local counter-slope, and it is difficult to find even a single blade of grass on the slope, except for the occasional gravel. What makes the quarry turn into an ecological product group is the unique technology of Jiangsu Green Rock Ecology Co.
Previously, the treatment and restoration of quarries and mining pits, people generally use engineering measures, or excavation of tree pits planted trees, or brick retaining grid mulch and then greening. Can we use natural methods to restore the natural ecology? To this end, Jiangsu Luyan Ecological Technology Co., Ltd. has successfully developed ecological restoration products called loam-like substrate to replace the mulch in the treatment; meanwhile, it has developed ropes made of plant fibers to replace wire, steel wire or plastic rope to weave soil fixing net. Zhang Bo, general manager of Jiangsu Green Rock Ecological Technology Co., Ltd. introduced that during the construction, the solid soil net was first installed on the steep bald rocks, and then a high-pressure mud pump was used to spray loam-like substrate into the solid soil net, and then seeds of trees, shrubs and grasses were scattered in proportion to the local plant communities. By the next year, "hair" had grown on the original bare stones.
"Using this technique not only restores the environment, but also thickens the soil layer year by year." Zhang Bo pointed to the tree has grown to three or four meters high mountain told reporters, by monitoring, the forest soil layer every year to 0.8 centimeters in the rate of thickening, the highest growth of trees has reached 15 meters. After the use of loam-like substrate technology, the treatment area vegetation and the surrounding original mountain appearance similarity in more than 90%, both soil and water conservation, purification of water bodies and other environmental protection role.
Wuxi City is based on the "ecological mountain", where an ecological product group has been built to create a scenic spot for citizens to enjoy ecological civilization.
