以腐熟玉米秸、麦秸、菇渣、锯末等农产废弃物等作为基质,添加有机肥和土壤,配成含有不同基质的有机土,并以一般土壤加有机肥作为对照,进行番茄栽培试验,以探讨不同基质中微生物数量、活性变化和土壤酶活性。结果表明,不同基质中真菌、放线菌总数、硝化细菌、纤维素分解菌总量有较大差别,且随番茄的生长时间呈增加趋势。以硝化细菌、氨化细菌所占比例最大,为优势类群,其次为真菌。不同有机土栽培下土壤微生物活度呈先增加后降低的趋势,土壤酶活性存在着明显的差异,脲酶、纤维素酶和磷酸酶活性分别高出土壤栽培4.76%～147.6%、11.48%～101.6%、14.29%～189.3%。有机土栽培较土壤栽培可有效增加微生物数量和酶活性,番茄根际生物活性受其生长发育进程和基质性状的双重影响。
Organic fertilizers and soils were added with maize straw, wheat straw, mushroom residue and sawdust as the substrates, organic manure with different substrates was dubbed, and the general soil and organic manure were taken as control to carry out tomato cultivation experiments. To explore the different matrix microbial quantity, activity and soil enzyme activity. The results showed that the total amount of fungi, actinomycetes, nitrobacteria, and cellulolytic bacteria in different matrices were quite different, and increased with the growth time of tomato. Nitrobacteria, ammoniated bacteria accounted for the largest proportion, the dominant group, followed by fungi. The activities of soil microorganisms increased firstly and then decreased under different organic soil soils. There were obvious differences in soil enzyme activities, soil urease, cellulase and phosphatase activities were 4.76% -147.6% and 11.48% -101.6 %, 14.29% ~ 189.3%. Compared with soil cultivation, organic soil could effectively increase the amount of microorganisms and enzyme activity. The rhizosphere biological activity of tomato was influenced by its growth and development process and matrix traits.
