Abstract：In order to study the effects of piggery bio-bed letter and its soil amendment on the yield and quality of pakchoi,soil physicochemical property,and soil microorganism,the field plot experiment was conducted.The results showed that,compared with the blank control group,the yields of the two tests applied with bio-bed letter and its soil amendment (hereinafter short for two treatments) increased by 14.25％ and 41.31％ respectively,the soluble sugar contents of pakchoi increased by 10.87％ and 41.30％ respectively,and the VC contents increased by 9.17％ and 16.45％ respectively,while heave metal Cd contents reduced by 39.69％ and 78.86％ respectively,and the heave metal Pb contents reduced by 44.74％ and 85.76％ respectively;the soil bulk density of two treatments reduced by 3.03％ and 1.94％,while soil porosity increased by 4.07％ and 1.43％,respectively,and the soil pH increased by 10.24％ and 15.61％,soil total salinity increased by 14.63％ and 4.89％ respectively compared with the control group;the number of soil bacteria of the two treatments increased by 11.58％ and 15.11％,the number of soil fungi increased by 14.81％ and 18.52％ respectively compared with the control group;the number of soil actinomyces of applying bio-bed letter treatment increased by 2.17％,while adding soil amendment treatment reduced by 22.47％ compared with the control group.
