Abstract

The invention belongs to the technical field of soil remediation, and discloses a remediation method and system for saline and alkaline land soil contamination. The system comprises a soil collectingmodule, a data processing module, a soil data comparison and classification module and a visualization module. Meanwhile, the invention discloses the remediation method. According to the remediation method and system for saline and alkaline land soil contamination, through the method including the steps of soil field studying, soil information collecting, soil treating, surface soil removing, soilexchanging, soil discharging, deep ploughing and ripping, acidic fertilizer applying, soil improving through crop planting, drainage ditch digging, scientific managing, scientific irrigating, fertilizer selecting and water quality improving, the steps are linked with one another from field studying to treatment implementing, measures are taken according to local conditions, and therefore the saline and alkaline land soil contamination treating success rate is greatly increased; in addition, the scientific education link is added in the end, and the land contamination speed is decreased from the source.

Description

technical field [0001] The invention belongs to the technical field of soil treatment, and in particular relates to a method and system for restoring soil pollution in saline-alkali land. Background technique [0002] In my country's coastal areas, the alkalinity of the soil will increase significantly after repeated cultivation, and due to improper cultivation patterns or external factors, the soil pollution is serious, and crops are grown on land with high salinity or pollution. , will reduce the yield and affect the quality of the product, so there is an urgent need for a reasonable remediation method for saline-alkali soil pollution. [0003] In recent years, hyperspectral imaging technology, which combines imaging technology and spectral technology, has developed rapidly and has been widely used in military and civilian fields. Therefore, processing and analyzing hyperspectral images collected by it has important application value. The hyperspectral image simultaneously...
