摘　　要：以废弃萝卜为主料,研究粉碎程度(不粉碎、粗粉碎、细粉碎)对萝卜堆肥养分及腐熟的影响。结果表明,粉碎程度越高,堆肥启动越快且温度累积越高;堆肥结束时,3个处理的有机质和总养分含量均能达到《有机肥料》(NY/T 525—2021)的要求,且粗粉碎处理的有机质含量显著高于其他2个处理(P<0.05);堆肥结束时,粗粉碎和细粉碎处理种子发芽指数分别为88.14%和88.07%,达到腐熟要求。因此,废弃萝卜在粗粉碎和细粉碎情况下均能堆肥成功,考虑到处理成本,建议萝卜堆肥时粗粉碎即可。The effect of crushing degree(no crushing,coarse crushing,fine crushing)on the nutrients and maturity of radish compost was studied with waste radish as the main material.The results showed that the higher the degree of crushing was,the faster the composting started and the higher the temperature accumulated.At the end of composting,the content of the organic matter and total nutrients of the three treatments could meet the requirements of“Organic Fertilizer”(NY/T 525—2021),and the organic matter content of the coarse crushing treatment was significantly higher than that of the other two treatments(P<0.05).At the end of composting,the germination index of seeds treated with coarse crushing and fine crushing was 88.14% and 88.07%,respectively,meeting the requirements for maturity.Therefore,waste radishes could be successfully composted in both coarse and fine crushing conditions.Considering the treatment cost,it was recommended to use coarse crushing during radish composting.
