Method for planting energy grass or ornamental grass on coastal saline and alkaline land

Abstract

The invention belongs to the field of coastal saline and alkaline land soil amelioration, and particularly relates to a method for planting energy grass or ornamental grass on coastal saline and alkaline land. The main improvement part of the method disclosed by the invention is that in an energy grass and ornamental grass plantation process, a compound biological ameliorant prepared by mixing vegetable waste, biochar and polypeptide preparations is added into a plantation hole. According to the method disclosed by the invention, since the compound biological ameliorant prepared by mixing thevegetable waste, the biochar and the polypeptide preparations is added into the coastal saline and alkaline land, a microenvironment around the coastal saline and alkaline land can be effectively improved so as to accelerate plant to grow and develop; the physicochemical properties of the coastal saline and alkaline land can be improved, volume weight is lowered, field water-holding capacity, total porosity and capillary porosity are improved, and meanwhile, the content of organic carbon is accelerated to improve; and soil microbial florae and ecological balance thereof can be improved, a soilgranular structure is accelerated to improve, and the soil fertility of the coastal saline and alkaline land is effectively improved.

Description

technical field [0001] The invention belongs to the field of soil improvement in coastal saline-alkali land, and in particular relates to a method for planting energy grass and ornamental grass in coastal saline-alkali land. Background technique [0002] Our country has up to 1.8×10 4 km of coastline, the coastal area is vast, and in the Bohai Rim alone, the area of ​​coastal tidal flats and saline-alkali wasteland reaches 6.8×10 5 hm 2 , as a reserve arable land resource development potential is huge. However, due to soil salinization, the vegetation coverage in the coastal saline-alkali area is relatively low. In the coastal saline-alkali area of ​​Caofeidian District, Tangshan City, Hebei Province, there are only a few sporadic plants with strong salt-alkali tolerance such as Suaeda glauca. To grow, it is necessary to take long-term and effective improvement measures to solve its ecological environment problems. [0003] Biological improvement refers to the applicatio...
