Abstract
Providing a method for improving saline-alkaline soil by using a biomass rapid pyrolysis product, comprising: rapidly pyrolyzing agricultural and forest residues to prepare bio-oil and semi-coke; deodorizing, dephenolizing and tackifying the bio-oil to prepare a modified bio-oil, and supplementing the modified bio-oil with the nutrient elements to produce a rapid ameliorant for saline-alkali soil; loading microbial fertilizer on the semi-coke to prepare a continuous renovation ameliorant for saline-alkali soil; (4) applying the ameliorants on the surface of saline-alkali soil. The method can not only enhance the aggregated and granulated structure of the saline-alkali soil and eliminate the salt carried by the capillary water, but also convert the mineral resource-based calcium, magnesium and ferrite salts which are insoluble and hardly absorbed into the humic acid calcium, magnesium and ferrite salts which can be easily absorbed, thereby activate calcium, magnesium and iron elements, strengthen soil fertility, rapidly renovate soil and restore the plantation function.
