摘　　要：利用延庆区玉米秸秆、蘑菇渣、芦苇和园林树枝作为原材料进行好氧发酵腐熟,混合好的腐熟物通过30%替代草炭、50%替代草炭、70%替代草炭和100%替代草炭,制成蔬菜栽培复合基质并分析其理化性质。结果表明,废弃物生产基质的安全性是有保障的;不同类型的农林废弃物腐熟的温度变化不同,但在45 d均可达到基质要求;物理性质方面,通气孔隙和持水孔隙均与草炭基质有显著差异;化学性质方面,pH属于正常范围内,养分元素(N、K、Ca、Mg)及电导率与草炭基质有不同程度的变化。Corn straw,mushroom residue,reed and garden branch in Yanqing District were adopted as raw materials for aerobic fermentation and compost maturity.Mixed maturation can produce vegetable cultivation medium and analyze its physicochemical property through 30%replaced peat,50%replaced peat,70%replaced peat and 100%replaced peat.The result showed that the medium produced from wastes had an ensured security.Since the maturation of different agricultural and forestry wastes might vary from each other in different temperatures,however,could meet the basic medium requirement within 45 days.In terms of its physical aspect,there was a significant effect with peat medium in ventilation and retention porosity while in its chemical aspect,pH value was still within the normal range and a different change was seen in nutrient elements like N,K,Ca and Mg and electric conductivity compared with peat medium.
