【摘要】：为了促进发酵床废弃垫料的循环利用,以猪菌渣发酵床垫料为原料,进行了堆肥腐解试验,测定了菌渣垫料堆肥的理化性状和重金属含量,开展了菌渣垫料堆肥种植甘蓝试验。结果表明,菌渣垫料堆肥中有机质、pH值、重金属含量均达到了有机肥料标准(NY 525-2012)要求,全氮、全磷、全钾的总养分含量为4.48%,略低于标准要求。用作底肥种植甘蓝,每公顷施用菌渣垫料堆肥6 000 kg时,甘蓝产量与施用相同用量商品有机肥无显著差异,随着菌渣堆肥施用量的增加,甘蓝产量呈增加趋势。
[Abstract]:In order to promote the recycling of the waste mats of fermentative bed, the compost decomposition test was carried out with the fermented bed pad of pig bacteria residue as the raw material, and the physical and chemical properties and heavy metal content of the compost were determined. The results showed that the pH value of organic matter and the content of heavy metals in the compost met the requirements of organic fertilizer standard NY 525-2012. The total nutrient content of total phosphorus and potassium is 4.48, which is slightly below the standard requirement. There was no significant difference between the yield of cabbage and the application of the same amount of commercial organic fertilizer. With the increase of the amount of microbial residue compost, the yield of cabbage showed an increasing trend.
