Abstract

Abstract: To explore the effect of recovery wilted elm by microbial organic fertilizer, 4 fertilization treatments were setting up, no fertilizer (B1), microbial organic fertilizer (T1), conventional organic fertilizer (T2), chemical fertilizer (T3). To guarantee the equal contents of N, P, K in soil, conventional ecological fertilizer (main component is crop straw) was used to modulate soil before formal 4 fertilization treatment experiment. Soil microbial population was detected at the 0th, 7th, 14th, 21st, 28th and 40th day, respectively from commencement of the experiment, growth condition of wilted plant was observed as well. The results showed, microbial organic fertilizer could increase microbial population in soil obviously, the microbial population was further increased with the prolonging of reaction time, the maximal quantity was 100×109 cfu/g. Enormous functional microorganism enhanced carbon conversion ratio of plant, complex strains and growth factors of microbial organic fertilizer could prevent and improve typical soil-borne diseases, such as bacterial wilt, root rot, fusarium wilt and phytophthora blight, as well as had significant effect of recovery wilted elm.
