- 摘要:
- 为了研究接种丛枝菌根真菌( AMF) 与间作种植模式对红壤上间作大豆磷素吸收利用及生长的影响,通过三室隔网盆栽模拟试验研究了分室磷[不添加磷( P0) 、有机磷( OP50) 添加和根室不接种( NM) 、根室接种丛枝菌根真菌Glomus mosseae( GM) ]对大豆生长及磷素利用的影响。结果表明: 在OP50 处理下,无论何种种植模式,不接种处理下根长均显著高于接种处理,无论接种与否,单作处理下大豆根长均高于间作处理。在OP50 处理下,接种GM 处理地上部分生物量均明显高于不接种处理,在P0 处理下地上部分生物量具有相同趋势。间作处理下,分室添加磷与不添加磷时,GM 处理的植株生物量较NM 处理分别提高了27. 52% 和48. 76%。单作处理下,分室添加磷与不添加磷时,GM 处理的植株生物量较NM 处理分别提高了28. 49% 和27. 65%。大豆植株根系磷含量在单作-GM-OP50 组合处理下最高。在接种GM 处理下,无论是否添加磷,间作大豆根系磷吸收效率均显著高于单作处理。因此,综合菌根侵染率、生物量、磷含量以及磷吸收效率等指标,接种GM 和分室添加50 mg·kg - 1 有机磷处理能更有效地促进间作大豆的生长及磷素的吸收。
- Abstract:
- Arbuscular Mycorrhizal Fungi ( AMF) could promote the soil properties,nutrients and growth of host plants. Intercroppingis a typical planting pattern for agricultural production,could obtain higher yield than monoculture. Intercroppingcrops could increase the utilization efficiency of nutrients especially for phosphorus ( P) in soil. The shortage of phosphate resourcesin the world is becoming more and more serious,researchers have paid more attention to intercropping or mycorrhizaltechnology to strengthen soil P utilization and increase crop yield. But little was known about the effects of combination of AMFinoculation and intercropping on plant growth and P utilization on red soil. The plant growth and P utilization of soybeans intercroppedwith maize ( Zea mays L. ) on red soil were investigated through pot experiment. Two different P treatment ways( none P [P0],organic P with 50 mg·kg - 1 soil [OP50]) to compartment chamber and two mycorrhizal treatments [no AMF( NM) and Glomus. mosseae inoculation ( GM) ]in root growth chamber were set up. Results showed that under OP50 treatment,regardless of planting modes,root length of GM treatment was significantly higher than NM treatment. For the intercroppingtreatment,comparing with NM treatment,biomass of GM plant was increased by 27. 52% and 48. 76% under OP50 andP0 treatment respectively,and for the mono-cropping treatment was 28. 49% and 27. 65% under OP50 and P0 treatment respectively.Under GM treatment,whether P addition or not,P SAR of intercropping soybean roots was significantly higherthan the mono-cropping treatment. Thus the treatment of AMF inoculation and organic P of 50 mg·kg - 1 application could promoteplant growth and P uptake by intercropped soybeans,which could effectively strengten organic P use in red soil.
