| 摘 要： | 将废弃蚕沙进行无害化处理和适度发酵开发出蚕沙有机肥,分析了其养分特点,并采用盆栽试验研究了蚕沙有机肥的肥效.结果表明:发酵蚕沙有机肥的全氮、全磷、全钾含量与堆肥前相比显著提高,分别比堆肥前提高了58.0%、84.4%和29.7%;添加微生物菌剂可有效缩短发酵时间,并能减少堆肥过程的碳、氮损失.施用发酵后蚕沙的小白菜和番茄种子的发芽指数均大于80%,对作物发芽没有抑制作用.施用发酵蚕沙有机肥不仅可提高小白菜产量、营养养分、Vc含量,减少硝酸盐积累量,还可提高土壤pH值,增加土壤速效养分和有机质含量,增强土壤酶活性,其效果优于发酵羊粪有机肥处理.

| Abstract: | In this paper,silkworm excrement was harmless-treated via controlled fermentation to prepare silkworm excrement organic fertilizer(SEOF).The nutrient properties of the SEOF were determined,and a pot experiment was conducted to examine the application effect of the fertilizer.After fermentation,the total N,P,and K contents in the SEOF had a significant increase,being 58.0%,84.4%,and 29.7% higher than those in the raw material,respectively.The addition of microbial inoculants shortened the fermentation period... |
