果树生物有机肥保质期试验研究

该试验以辽宁省果树科学研究所土壤肥料研究室研制的果树专用粉状生物有机肥、颗粒状生物有机肥及添加氮磷钾化肥的生物有机无机复混肥3种肥料为试材,于肥料生产后1个月开始检测肥料的有益菌数量、有机质、水分和氮磷钾含量,确定其合理贮藏期。检测结果表明,3种生物有机肥中,以粉状未添加化学肥料的生物有机肥保质期最长,颗粒状生物有机肥保质期符合国家保质期标准,而添加化学肥料的生物有机无机复混肥应适量减少化学肥料的添加量,或缩短贮藏期限。

Study on Shelf Life of Fruit Tree Bio-organic Fertilizer

The experiment take fruit-specific powder bio-organic fertilizer,granular bio-organic fertilizer and add NPK organic-inorganic composite fertilizer as materials.in the We started to detect the number of beneficial bacteria fertilizer,organic matter,water and total NPK one month after production and to determine its reasonable storage period. Results indicated： Of the three different organic fertilizer,powdery bio-organic fertilizer without adding chemical elements was keeping the longest, granular organic fertilizer shelf life expiration date accord with national standard, and add NPK organic-inorganic composite fertilizer should be ade-quate reduce the amount of chemical elements, or shortening the shelf life.
