NOVELTY - Vegetation restoration of coastal heavy saline-alkaline soil ecologically fragile area comprises turning and loosening the soil by plowing the land, crushing clods, leveling the land, application of soil microbial fertilizer, diluting nutritional solution with hot water for three times, adding probiotic stock solution, mixing uniformly to obtain microbial inoculum, mixing farmyard manure and soil, continuously spraying microbial inoculum, mixing, adding water, covering a plastic film, stacking to ferment, applying on soil, repeating the turning process, and transplanting or planting.    USE - The method is useful for vegetation restoration of coastal heavy saline-alkaline soil ecological fragile area (claimed).    ADVANTAGE - The method: improves saline alkali effect in a short time (growing season), reduces high salt-alkali soil to prevent secondary basification; increases the soil fertility; establishes microbial community, which accelerates the curing degree of the soil, promotes heavy saline-alkali soil vegetation progress, ensures annual survival rate of the plants (more than 95%); is economical; and saves water resources.    DETAILED DESCRIPTION - Vegetation restoration of coastal heavy saline-alkaline soil ecologically fragile area comprises (a) turning and loosening the soil by plowing the land 30 cm, crushing clods, leveling the land, where the height difference is not greater than 5 cm, (b) selection and application of soil microbial fertilizer including two fertilizers, (b1) diluting nutritional solution with hot water for three times, adding probiotic stock solution, mixing uniformly, process to obtain microbial inoculum, mixing farmyard manure and soil in a ratio of 10:1, continuously spraying microbial inoculum, mixing, adding water to make the water content to be 45%, covering a plastic film, stacking to ferment for 15-25 days, adding ozone-free variable incense e.g. gold (sic) to obtain 30 g/kg probiotic bacterial fertilizer, planting into 20 cm plowed depth, uniformly applying the probiotic bacterial fertilizer on the soil, repeating the turning process for two times, (b2) the second of and A + F, planting, selecting and A + F (1 1), applying fertilizer to and A + F (in a mass ratio of 1:1) is 0.4 g/kg, planting according to the plowing depth is 20 cm deep; and F are applied to soil directly up, repeating plowing, then and A is added with 100 times water is sprayed on the same block up, and (c) transplanting or planting.
