china fertilizer production system with advanced technology

  • Energy and water footprints of cereal production in China

    Due to that excessive irrigation is a common practice in Chinese agricultural production (Zou et al. 2020 Wang et al. 2016) optimizing the irrigation system and improving the efficiency of irrigation water are urgent for cereal production in China. Watersaving infrastructures including drip irrigation sprinkler irrigation and integrated management of water and fertilizer have been

  • Current Status and Challenges of Rice Production in China

    The major problems confronting rice production in China are narrow genetic background overuse of fertilizers and pesticides breakdown of irrigation infrastructure oversimplified crop management and a weak extension system. Despite these challenges good research strategies can drive increased rice production in China. These include the development of new rice varieties with high yield

  • Rice Production in China SpringerLink

    Based on the climate and cropping systems rice production in China has been classified into six agroecological zones and 15 subzones (China National Rice Research Institute 1988). 2.4 RiceBased Cropping Systems. Southern China is the main rice production area in China accounting for 94 % of national rice planting area and 88 % of national rice production (Ma et al. 2013). The ricebased

  • Quantifying N response and N use efficiency in ricewheat

    About 0䞆 of the food supply in China is produced in ricewheat (RW) cropping systems. In recent decades nitrogen (N) input associated with intensification has increased much more rapidly than N use in these systems. The resulting nitrogen surplus increases the risk of environmental pollution as well as production costs. information on N dynamics in RW systems in relation to water

  • Integrated soilcrop system management for food security

    China and other rapidly developing economies face the dual challenge of substantially increasing yields of cereal grains while at the same time reducing the very substantial environmental impacts of intensive agriculture. We used a modeldriven integrated soilcrop system management approach to develop a maize production system that achieved mean maize yields of 13.0 t ha1 on
