本文研究冬小麦间作板蓝根对小麦生长和麦田CH4通量的影响,并对其进行经济与环境效益分析。试验在南京信息工程大学农业气象试验站采用田间小区试验进行,采用静态箱(暗箱)0气相色谱法在小麦生育期定期取样分析麦田CH4通量,同时记录不同处理下小麦的生物量,收获后测定小麦及板蓝根产量。结果表明,与对照施肥单作处理(NPKW)相比,施肥间作板蓝根处理(NPKWR)小麦产量与千粒重分别增加9%和1%;冬小麦田CH4的通量主要是吸收,吸收量表现为施肥间作板蓝根处理(NPKWR)>不施肥处理(N0P0K0W)>裸地(N0P0K0W0)>施肥单作处理(NPKW),施肥间作板蓝根处理(NPKWR)比施肥单作处理(NPKW)冬小麦田的CH4吸收量累计增加34%,间作模式使板蓝根与小麦综合增产5%,每公顷多盈利2017.25元。本研究表明冬小麦间作板蓝根为提高土地资源利用率、发展低碳农业、增加经济效益环境效益提供一项新技术。
This paper studies the effect of winter wheat intercropping Banlangen on wheat growth and wheat field CH4 flux, and its economic and environmental benefits analysis. The experiments were carried out in a field experiment at Nanjing Agricultural University using the static chamber (dark box) 0 gas chromatography method to periodically sample and analyze CH4 flux in the wheat field during the growth of wheat and record the biomass of wheat under different treatments. After harvesting Determination of wheat and Radix production. The results showed that the yield and thousand-grain weight of NPKWR increased by 9% and 1%, respectively compared with NPKW. The fluxes of CH4 in winter wheat were mainly absorbed and absorbed, (NPKWR)> NPKW> N0P0K0W0> NPKW, NPKWR was higher than that of NPKW in winter wheat field 34%, intercropping mode so that the combined production of Banlangen and wheat increased by 5%, more profit per hectare 2017.25 yuan. This study showed that the winter wheat intercropping Banlangen to provide a new technology to improve the utilization of land resources, the development of low-carbon agriculture, increase economic efficiency and environmental benefits.
