中文摘要:以猪粪为堆肥原材料,以玉米秸秆粉为调理剂,并添加干质量分数为0、2.5%、5.0%、7.5%和10%的粉煤灰进行90 d好氧堆肥,研究不同用量粉煤灰对猪粪堆肥过程中养分转化的影响。结果表明:添加粉煤灰能提高堆体的pH值,但在后期对电导率(EC)的增加有一定的抑制;碳氮比随着堆肥时间的延长而降低,而总氮(TN)则相反;当粉煤灰质量分数达10%时,在60d后堆体TN明显降低;添加粉煤灰对NH+4-N无明显影响,而所有添加粉煤灰均会抑制堆肥中NO3-N 的生成,且与粉煤灰用量呈正相关;添加粉煤灰对总磷(TP)和总钾(TK)的影响不大,但会抑制雪里蕻根部的生长。结合发芽率试验结果可以认为,90 d的试验中所添加的粉煤灰对猪粪堆肥的腐熟没有影响。

Abstract:Swine manure was mixed with corn stalk powder as a bulking agent, and the mixtures were amended with flyash at 0, 2.5%, 5.0%, 7.5% and 10% and composted for 90 days. Addition of flyash raised the pH value of the swine manure compost throughout the composting period, but significant inhibited the rise of electricity conductivity during the later period with the ratio of flyash increasing. C/N ratio decreased according to composting time, whereas total N showed an opposite trend for all treatments except 10% flyash was amended. There was no significant loss ofNH+4-N during the thermophilic phase by ash amendment. While, addition of flyash also inhibited the nitrification process as indicated by the lower soluble NO3-N content in ash-amended swine manure composts but had no effect on TP and TK increasing. The GI and germination rate of potherb mustard (Ardisiasquamulosa presl) seed increased with composting time, while the root growth was significant inhibited when flyash was amended and the germination rate indicated that flyash amendment did not affect compost maturity in 90 days composting.

Transactions of the Chinese Society for Agriculture Machinery (CSAM), in charged of China Association for Science and Technology (CAST), sponsored by CSAM and Chinese Academy of Agricultural Mechanization Science(CAAMS), started publication in 1957. It is the earliest interdisciplinary journal in Chinese which combines agricultural and engineering. It always closely grasps the development direction of agriculture engineering disciplines and the published papers represent the highest academic level of agriculture engineering in China. Currently, nearly 8,000 papers have been already published. There are around 3,000 papers contributed to the journal each year, but only around 600 of them will be accepted. Transactions of CSAM focuses on a wide range of agricultural machinery, irrigation, electronics, robotics, agro-products engineering, biological energy, agricultural structures and environment and more. Subjects in Transactions of the CSAM have been embodied by many internationally well-known index systems, such as: EI Compendex, CA, CSA, etc.
