中文摘要:进行了生物质炭—化肥互作试验,探究炭—肥互作对红壤养分、芥菜产量、肥料利用率的影响。采用盆栽试验,设置空白对照组CK(不加炭,不施肥)、加炭组(施加5%的稻壳炭),按照化肥投入量的递减率为0、15%、30%、45%,依次标记为RFC0、RFC1、RFC2、RFC3,对应的不加炭处理依次记为RF0、RF1、RF2、RF3。结果表明,添加5%的稻壳炭、化肥施用量为常规施肥量的55%(RFC3)时,氮肥表观利用率最高,炭—肥互作处理的氮肥利用率均显著高于常规施肥处理,平均提高161.42%,而加炭处理(RFC0、RFC1、RFC2、RFC3)的芥菜产量分别比对应的不加炭处理平均提高79.28%。炭—肥互作组的红壤有机质含量比单施化肥组平均高出241.42%;RFC3处理的红壤碱解氮、有效磷含量均高于RF0处理,说明炭可以增加土壤养分,当施肥量为常规施肥量的55%时,生物质炭与化肥互作,保持了土壤的有效养分。另外,炭—肥互作的种植模式也促进了芥菜对氮、磷、钾养分的吸收和贮藏。在本试验条件下,降低肥料投入时,生物质炭发挥其对红壤的综合改良效应及其对养分的吸收和固持作用,从而表现出显著的增产效应;炭—肥互作模式可以在低肥料投入时通过提高肥料表观利用率、氮肥利用率来保证作物的养分供给,保持土壤的肥力,使作物增产。

Abstract:The effect of interaction of biochar and fertilizer (IBF) on nutrients of red soil, yield of mustard and fertilizer utilization rate was investigated. IBF experiments were conducted, the treatments included RFC treatment (both biochar and fertilizer were applied), RF treatment (only fertilizer applied) and control treatment CK (no biochar and fertilizer applied). The fertilizer application dosages were 100%, 85%, 70%, 55% of the regular fertilizer application quantity, which were correspondingly denoted as RFC0, RFC1, RFC2, RFC3 of RFC treatment and RF0, RF1, RF2, RF3 of RF treatment, respectively. The results showed that the nitrogen utilization rate of RFC3 was higher than those of other treatments. The nitrogen utilization rate, yield of mustard and the soil organic matter content of RFC treatments were averagely increased by 161.42%, 79.28% and 241.42% compared with those of RF treatments, respectively. The alkali-hydrolyzable nitrogen and available phosphorus contents of RFC3 were higher than those of RF0. Additionally, IBF planting pattern promoted mustard to adsorb and accumulate N, P, K effectively. In conclusion, biochar played an important role in nutrients adsorption and enrichment for mustard growth. The mechanism of yield increment and soil fertility enhancement could be explained that the IBF planting pattern brought the comprehensive amendment effect in the red soil and provided mustard with sufficient nutrients by biochar’s adsorption and fixation for nutrients, which made fertilizer and nitrogen fertilizer utilization rate increase significantly, although the application amount of fertilizer was very low in the experiment.

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.
