摘要
该研究以木薯茎秆为主要原料,鸡粪、蔗渣、有机废物发酵菌曲为辅料将其堆肥基质化处理,旨在探讨木薯茎秆堆肥基质化处理的最佳发酵工艺及评价不同处理腐熟后的品质。研究结果表明,基质发酵过程中,其主要理化指标堆温、总碳(TC)、总氮(TN)、碳氮比(C/N)、pH值、全K(TK)、全P(TP)、电导率(EC)等随堆制时间呈现一定的变化规律。基质腐熟后的各项理化指标基本达到栽培基质的要求。综合基质的发酵温度、腐熟周期及无土栽培基质对基质各项理化性质的要求,处理2(木薯茎秆+菌+鸡粪)、处理3(木薯茎秆+菌+鸡粪+甘蔗渣)更适合木薯茎秆堆肥基质化处理。
In this study cassava stalk as main material,was used to transform into organic substrate with auxiliaries of chicken manure,sugarcane bagasse and fermenting bacteria of organic waste. The experiment was conducted aimed at probing the best process of fermentation and evaluating the quality of substrate. The results indicated that the main indexes of substrate,including composting temperature,total carbon （TC）,total nitrogen （TN）,value of TC divided TN,pH,total phosphorus （TP）,total potassium （TK）,and electrical conductivity （EC） showed some regular changing trends. Physical and chemical properties of substrate were suitable for cultivation. Treatment 2 （stalk of cassava ＋ fermenting bacteria of organic waste ＋ chicken manure） and treatment 3 （stalk of cassava ＋ fermenting bacteria of organic waste ＋ chicken manure ＋ sugarcane bagasse） were more appropriate for organic substrate production considering the effect on composting temperature,composting duration and physical chemistry indexes of soilless planting substrate.
