英文摘要	With the increase of biogas production, its residues (digestate) multiplied and how to use it effectively and promote any negative influences on soil and environment were concerns of researchers. In present study, the usefulness of liquid digestate as a fertilizer and its effects on plant and soil environment were evaluated in greenhouse experiments via integrated hole irrigation, during two successively growing seasons in 2016 and 2017. The effects of various contents digestate application were compared with those of conventional chemical fertilizer and no fertilizer applied. Five treatments, including T1 (digestate: water, 1: 4), T2 (digestate: water, 1: 6), and T3 (digestate: water, 1: 8), CK (no fertilization), CF (conventional chemical fertilization), were set up. The results showed that the appropriate digestate addition to soil had positive effects on tomato growing such as the plant height, stem diameter, dry biomass concentration and finally increased the yields and quality, compared to CF and CK. The yield of T1, T2 and T3 treatments increased about 9.01%, 6.6% and 5% in autumn and 13.22%, 10.03% and 5.71% in spring in comparison with CK, while that increased by 3.04%, 0.72% and - 0.76% in autumn and 5.71%, 2.73% and - 1.3% in spring in comparison with CF. The titratable acid, total soluble sugar, Vc, soluble protein, soluble solids content, and firmness of tomato in T1 and T2 treatments were all higher than CF and CK, demonstrated that digestate application can obtain a superior fruit quality and taste. The NAUE and surplus content of nitrogen in crop rootzone of T1 and T2 treatments were higher than other treatments, meanwhile the total nitrogen content in the depth of 60 cm was relatively stable before and after planting, which showed the nitrogen-fixing effect of digestate and there were no nitrogen pollution in soil environment. Considering the growth, yield, quality of tomato and the NAUE, T1 and T2 treatments both can obtain the satisfactory effects as a fertilizer and can be used as the substitute of conventional chemical fertilizer in agricultural production.
