| 摘 要： | 以猪粪和米糠为原料进行高温好氧堆肥,测定堆肥几项腐熟度指标的变化.结果表明,堆肥后与堆肥前有机物料的碳氮比(T值)、NH4+-N/NO3--N均随堆肥化的进行而下降,种子发芽指数(GI)则上升,T值、NH4+-N/NO3--N与GI呈显著负相关.不同腐熟度堆肥的甜椒盆栽试验表明,施用堆制0、7和14 d堆肥的甜椒,其生物量较施用堆制30和55 d堆肥的处理极显著降低,而施用堆制30和55 d堆肥的甜椒生物量没有明显差异.以35 d堆肥的GI、T值、NH4+-N/NO3--N作为堆肥腐熟度的指标,腐熟指标是GI≥45%、T≤0.65、NH4+-N/NO3--N≤0.60. |

| Abstract: | A compost experiment using swine manure and rice bran was conducted to study the change of compost maturity indices.The results showed that T-value,NH+4-N/NO-3-N ratio were reduced to some degree after 56 days′ composting and GI was raised apparently.Correlation analysis showed that T-value as well as NH+4-N/NO-3-N ratio was significantly negative to GI.The result of pot experiment using different maturity composts to cultivate sweet pepper showed that the biomasses of pepper adding 30 day or 55 day fermentation compost were significantly higher than those of 0 day,7 day,14 day treatments;but there was no significant difference between the biomass of pepper adding 30 day fermentation compost and that of adding 55 day fermentation compost.35 day fermentation compost′s maturity parameters were chosen as maturity indices.The maturity indices were GI≥45%,T≤0.65 and NH+4-N/NO-3-N ratio≤0.60. |
