Characteristics of water consumption in water-saving winter wheat and effects on the utilization of subsequent summer rainfall in the North China Plain
Winter wheat (Triticum aestivum L.) grows in dry season but summer maize (Zea mays L.) coincides with rainfall in the North China Plain (NCP). Increasing rainfall use efficiency and harmonizing its utilization between the two species is an effective way to mitigate impact on groundwater deriving from wheat irrigation. One to four times water supply (W1, to W4) were employed in wheat, three wate...
متن کاملEffect of Nitrogen and Irrigation Application on Water Movement and Nitrogen Transport for a Wheat Crop under Drip Irrigation in the North China Plain
For improving water scarcity and groundwater pollution from agriculture, two-year experiments (2011–2013) with three water levels (0.3, 0.5 and 0.8 evaporation (E) in 20-cm-diameter pans) and four nitrogen (N) levels (120, 140 and 190 kg·ha−1 in 2012 and 120, 190 and 290 kg·ha−1 in 2013) were conducted to study effects of water and N availability on water movement and N transport for a wheat cr...

متن کاملEffects of sowing time and rate on crop growth and radiation use efficiency of winter wheat in the North China Plain
Crop depends on its canopy to intercept solar radiation to drive both assimilation and water, nutrient absorption for its growth. Field experiments, involving three sowing time and three sowing rate, were conducted at Luancheng Station to investigate the effects of canopy size and development on crop growth and radiation use efficiency (RUE) of winter wheat during 2009/2010 and 2010/2011 gr...
متن کاملEvaluating the Crop Water Stress Index and its correlation with latent heat and CO2 fluxes over winter wheat and maize in the North China plain
Plant water status is a key factor impacting crop growth and agricultural watermanagement. Cropwater stress may alter canopy temperature, the energy balance, transpiration, photosynthesis, canopy water use efficiency, and crop yield. The objective of this study was to calculate the Crop Water Stress Index (CWSI) from canopy temperature and energy balance measurements and evaluate the utility of...
