Abstract
The invention provides a spray seeding matrix which is prepared from main materials and assistant materials. The main materials comprises the following materials by mass: 8-12 parts of soils for planting, 6-9 parts of turfy soils, 1.2-1.8 parts of straws, and 1.2-1.8 parts of attapulgite powder; the assistant materials is mainly composed of polyacrylamide and organic fertilizers. The greening method for saline land adopting the spray seeding matrix comprises: uniformly applying a mixture selected from one or more of desulfurized gypsum, calcium superphosphate, cow dung, and humic acid on the soil surface, forming a simple improvement layer, covering a mixture selected from one or more of furnace ash, wheat bran, sawdust, barks and straws on the simple improvement layer to form a saline-alkaline separating layer, and covering the spray seeding matrix on the saline-alkaline separating layer. The method for saline land greening is simply operated, and the plants in the modified saline land grow fine.
Description
technical field [0001] The invention relates to the field of environmental management, in particular to a spraying substrate and a method for greening saline-alkali land by using the spraying substrate. Background technique [0002] With the rapid economic development of Binhai New Area, the contradiction between the shortage of land resources and the large amount of land used for economic development has become increasingly prominent. Land reclamation is an effective way to expand ports, industrial development space and urban construction land. In recent years, coastal areas have been rapidly expanded to shallow seas and tidal flats. Land reclamation is unstoppable. As the area of land reclamation continues to increase, The dredger reclamation area has become an important land resource for the economic and social development of Binhai New Area. [0003] The land formed by dredging filling, after the completion of infrastructure construction, due to the lag in attracting ...
