The characteristics of overland ̄ow under varied tillage and cropping systems in Sichuan Basin, China
نویسندگان
چکیده
Data from runoff plots operated over a ®ve year period show that signi®cantly less overland ̄ow is generated with a seasonal no-till ridge system than with contour tillage or straight tillage systems. Seasonal no-till ridge is the optimum system for increasing the availability of water for rainfed agriculture on the dryland soils in the hilly area of Sichuan Province, China. # 2000 Published by Elsevier Science B.V.

Integrative impacts of soil tillage on crop yield, N use efficiency and greenhouse gas emission in wheat-corn cropping system
Wheat-corn cropping system is one of the most important grain production systems in theworld. However, the integrative impacts of soil tillage on crop yield, N use efficiency (NUE)and greenhouse gases (GHGS) emissions are not well documented in this system. Thus, a twoyear field experiment was carried out in a typical wheat-corn cropping system with four tillageregimes during the wheat season, ...
متن کاملDetermination of Time of Oil Cracking into Gas in Weiyuan Paleo-Oil Pool in Sichuan Basin, South China
Weiyuan gas field, located in the Sichuan basin of south China, is a large marine gas field with the oldest reservoir (the Sinian sequences) in south China. The hydrocarbon origin of the gas field has long been debated by petroleum geologists. Recently, it was recognized that a paleo-oil pool maybe the significant contributor to the gas field. Consequently, when the paleo-oil pool had been crac...
متن کاملMore aboveground biomass, phosphorus accumulation and remobilization contributed to high productivity of intercropping wheat
Intercropping often results in increasing production than sole per unit land area, but theunderlying mechanisms are poorly understood. Plants showed different physiologicalcharacteristics in intercropping and sole. However, less information was shown the relationshipsbetween plant aboveground biomass (AB), phosphorus accumulation (PB) and remobilizationand the yield advantage. Here, field exper...

The measurement of carbon isotope discrimination (∆) provides an integrated insight into theresponse of plants to environmental change. To investigate the potential use of ∆ for identifyingshade tolerance in rice, five rice varieties were selected and artificially shaded (53% lightreduction) during the grain-filling period in 2010 and 2011, in Sichuan, China. Shadingtreatment had a significant ...
متن کاملCropping systems, tillage and fertilization strategies for durum wheat performance and soil properties
Many sustainable agronomical practices can be adopted to contain environmental risks of crop production and, at the same time, sustain yield and quality. In this framework, the aim of this research was to study the effects of continuous cropping (CC) and crop rotation, tillage and fertilization strategies on durum wheat (Triticum durum Desf.) production. The responses of soil properties we...
