| 为探明麦秸秸秆花盆堆肥化过程养分变化规律,为废弃秸秆花盆堆肥化处理提供理论参考,提出将秸秆花盆粉碎物料(Crushed straw flowerpots,CSF)分别与半腐熟有机肥(4份腐熟平菇渣+1份腐熟中药渣+1份新鲜金针菇渣)按照干质量比0:10(CK)、1:10(TⅠ)、2:10(TⅡ)、3:10(TⅢ)混合进行4种处理堆腐发酵试验,研究秸秆花盆堆肥化阶段理化性状动态变化,并结合综合性腐熟评价指标——种子发芽指数(GI),对其堆腐程度进行评价。结果表明:CSF添加量对堆腐温度、pH及水分变化无显着影响,但显着影响了堆腐发酵产物中有机碳和全氮含量,全氮随CSF添加量的增加显着升高,TⅠ、TⅡ和TⅢ3个处理堆腐结束与初期的全氮含量相比均有所下降,表明添加适量CSF后会发生氮素的降解。氮形态分析发现,CSF的添加可提高堆腐发酵产物中铵态氮相对含量,堆腐初期氨基酸态氮和氨基糖态氮存在上升趋势,适量添加CSF利于植株生长及微生物的活动;反映种子活力的GI指标分析结果显示,TⅠ、TⅡ和TⅢ处理的GI值均高达0.8,表明添加CSF堆腐优于CK,可削弱对种子萌发的毒害作用。 |

| Utilizing straw flowerpots to grow plant seedlings and ornamental plants would promote comprehensive use of crop straws. However, how to dispose discarded straw flowerpots has become a new concern. The present study investigated dynamics of nutrients in crushed straw flowerpot(CSF) during composting. Seed germination index(GI) of composted flowerpots was also examined. The composting experiment included four treatments, which was CSF amended with partially composed material mix(PCMM) of composed mushroom residues:composted Chinese medicinal dregs:fresh flammulina residues of 4:1:1 at 0:10(CK), 1:10(TⅠ), 2:10(TⅡ), and 3:10(TⅢ). Results showed that CSF amount had no significant effects on temperature, pH and moisture during composting, but significantly influenced total carbon and nitrogen, which increased significantly with CSF rates. CSF increased ammonium nitrogen(NH4+-N) in the composts. The content of amino acid nitrogen and amino sugar nitrogen in the composts had a rising trend, which was beneficial to plant growth and microbial activity. The greater GI values in all CSF treatments than CK indicated that composting process made the compost harmless. Temperature, moisture content, pH, organic carbon, TN and GI could be used as indexes for evaluating compost maturity. |
