The Nitrogen Cycling Key Functional Genes and Related Microbial Bacterial Community α−Diversity Is Determined by Crop Rotation Plans in the Loess Plateau

چکیده
Soil nitrogen cycling microbial communities and functional gene α−diversity indicate soil ecological functions potentials. Crop rotation plans affect fractions these indicators. We sequenced samples from four crop (fallow, winter wheat monoculture, pea-winter wheat-winter wheat-millet rotation, corn-wheat-wheat-millet rotation) in a long-term field experiment. examined how changed with regulated them. Planting crops increased the abundance richness of key genes bacterial compared fallow. The correlated positively fractions, while Shannon index did not. total (STN) potential mineralization (PNM), showed that then decreased increasing STN PON. Introducing legumes into improved genes. These results can guide sustainable agriculture Loess Plateau clarify relationship between

Response of the Abundance of Key Soil Microbial Nitrogen-Cycling Genes to Multi-Factorial Global Changes
Multiple co-occurring environmental changes are affecting soil nitrogen cycling processes, which are mainly mediated by microbes. While it is likely that various nitrogen-cycling functional groups will respond differently to such environmental changes, very little is known about their relative responsiveness. Here we conducted four long-term experiments in a steppe ecosystem by removing plant f...

abstract while task-based instruction is considered as the most effective way to learn a language in the related literature, it is oversimplified on various grounds. different variables may affect how students are engaged with not only the language but also with the task itself. the present study was conducted to investigate language and task related engagement on the basis of the task typolog...
15 صفحه اولBacterial Community Responses to Soils along a Latitudinal and Vegetation Gradient on the Loess Plateau, China
Soil bacterial communities play an important role in nutrient recycling and storage in terrestrial ecosystems. Loess soils are one of the most important soil resources for maintaining the stability of vegetation ecosystems and are mainly distributed in northwest China. Estimating the distributions and affecting factors of soil bacterial communities associated with various types of vegetation wi...
متن کاملThe Loess Plateau
The Loess Plateau (34°–40°N, 103°–114°E) is situated in the northern part of Central China (Fig. 2.1). It borders on North China Plain in the east, adjoins Qinghai-Tibet Plateau in the west, stands in the north of Qinling Mountains, and neighbors Inner Mongolia Plateau in the north. The Loess Plateau is a part of the dryland region in northwest China, with its altitude in the range of 800–3000 ...
