在大田条件下,采用随机区组设计研究了春播覆膜(CBFM)、春播露地(CBLD)、麦田套种(MT)、麦田套种露地对照(MTLD)、夏播覆膜(XBFM)和夏播露地(XBLD)6种花生种植方式对土壤微生物生物量碳、活跃微生物生物量和土壤呼吸的影响.结果表明:花生生育期和种植方式均显著影响土壤微生物生物量及活性.从始花期开始,随着生育进程的推进,土壤微生物生物量碳、活跃微生物生物量和呼吸速率逐渐升高,到结荚期达到最大值,随后下降.露地栽培花生提高了土壤微生物生物量碳和土壤呼吸速率,但是降低了活跃微生物生物量,对土壤养分的转化和吸收不利;覆膜花生提高了活跃微生物生物量,促进土壤养分的分解和有效化;麦田套种花生比同期播种的露地对照花生提高了土壤微生物生物量碳、活跃微生物生物量和土壤呼吸速率,固结养分较多,不利于花生生长.
Under field conditions, the effects of CBFM, CBLD, MT, MTLD, XBFM and summer sowing were studied using randomized block design. (XBLD) on soil microbial biomass carbon, active microbial biomass and soil respiration were studied.The results showed that both the growth period and planting mode of peanut significantly affected soil microbial biomass and activity.From the beginning of flowering period, With the development of fertility, soil microbial biomass carbon, active microbial biomass and respiration rate increased gradually, reaching the maximum at podding stage and then decreased.The amount of soil microbial biomass carbon and soil respiration rate in open-field peanut increased Reduced the active microbial biomass and adversely affected soil nutrient conversion and absorption. The peanut-coated peanut improved the active microbial biomass and promoted the decomposition and effectiveness of soil nutrients. The peanut intercropping increased the soil microbial biomass Amount of carbon, active microbial biomass and soil respiration rate, more consolidated nutrients, is not conducive to peanut growth.
