NOVELTY - A yellow flashing saline-alkali field chemical sand soil improving method involves forming organic compost; spreading fertilizer, prepared organic compost uniformly laying spreading the plant planting area, planting the lower section surface of the first surface of the semiconductor layer and unfolding the organic compost, then levelling terrain when planting like acid arbor and flowering shrubs, packing the mixture in the compost and plant planting hole dug original soil according to 1:1 of proportion, then backfilling tamping.    USE - As yellow flashing saline-alkali field chemical sand soil improving method (claimed).    ADVANTAGE - The method is suitable for planting and ecological landscape construction; makes full use of the garden maintenance and management to produce green; is economical and practical; effectively maintains and improves the ecological environment.    DETAILED DESCRIPTION - A yellow flashing saline-alkali field chemical sand soil improving method involves manufacturing organic compost by crushing leaf, branch by crusher, crushing length of the branch is controlled within 12 cm, setting the leaf and the branch, adding water, where the material-water quantity ratio is 1: 2 to 3 to compost pool, adjusting the mixture is nitrogen of the material C, adding in micro organism decomposing and EM strain in the material to every cubic meter material into 1~2 of EM stock solution, each cubic meter of material into the EM stock solution by water to dilute to 20, spraying the material, and then uniformly stirring material, putting the material piling mountain shape or trapezoid strip for fermentation, the material stack, plastic cloth and upper cover shielding material, where the fermentation process, turning for 5-7 days of the first stack, turning time is more; spreading fertilizer, prepared organic compost uniformly laying spreading the plant planting area, planting the lower section surface of the first surface of the semiconductor layer and unfolding the organic compost, then levelling terrain when planting like acid arbor and flowering shrubs, packing the mixture in the compost and plant planting hole dug original soil according to 1:1 of proportion, then backfilling tamping.
