| 英文摘要 | Precision agriculture (PA) has been suggested as a management tool to increase crop performance and improve environmental quality. Few studies have simultaneously investigated the economic and environmental benefits of PA. This study aims to evaluate the effects of PA technology on winter wheat yield and residual soil nitrogen in central China. Three treatments, single precision seeding technology (PS), integrated precision seeding with laser land leveling technologies (PLS), conventional land leveling and conventional seeding technologies (CLS) were evaluated in winter wheat cropland of central China. Wheat yield components and residual soil nitrogen were measured in harvest time. The abundance of soil ammonia-oxidizer archaea (AOA) and soil ammonia-oxidizer bacteria (AOB) was determined using real-time PCR polymerase chain reaction to explore the microbial mechanisms of residual soil nitrogen under PA application. The result showed that PLS treatment rather than PS treatment significantly increased wheat yield, straw biomass and wheat nitrogen uptake after one season of application. PS and PLS treatments resulted in significant increase of C/N ratio, while only PLS treatment significantly increased soil pH value. Furthermore, PS treatment significantly reduced residual soil NO3--N and NH4+-N, whereas PLS treatment only significantly decreased residual soil NH4+-N. Both PS and PLS treatments did not affect the abundance of AOB amoA gene copy numbers, but significantly stimulate the abundance of AOA amoA gene copy numbers. These results indicate that PA application reduced residual soil nitrogen via changing the abundance of AOA resulting from the increased C/N ratio and soil pH value. Our study also suggested that integrated PLS treatment was the good application pattern than single PS treatment to improve wheat yield and reduce residual soil nitrogen.
