Partitioning of Cotton Field Evapotranspiration under Mulched Drip Irrigation Based on a Dual Crop Coefficient Model
Estimation of field crop evapotranspiration (ETc) and its partitioning into evaporation and transpiration, are of great importance in hydrological modeling and agricultural water management. In this study, we used a dual crop coefficient model SIMDualKc to estimate the actual crop evapotranspiration (ETc act) and the basal crop coefficients over a cotton field in Northwestern China. A two-year ...
متن کاملRelationships between carbon fluxes and environmental factors in a drip-irrigated, film-mulched cotton field in arid region
Environmental factors and human activities play important roles in carbon fixation and emissions generated from croplands. Eddy covariance measurements in a drip-irrigated, film-mulched cotton field were used to analyze the relationships between carbon fluxes and environmental factors in Wulanwusu, northern Xinjiang, an arid region of Northwest China. Our results showed that the cumulative net ...
متن کاملLint yield and seed quality response of drip irrigated cotton under various levels of water
Restricted water resources are a limiting factor for irrigation applications throughout the world. The effects of irrigation regimes (amount) on cotton lint yield are known, but there is little information on the effect of irrigation regimes on seed quality of cotton. In this study, the effects of deficit irrigation after the onset of flowering on lint yield and seed quality of cotton (Gossypiu...
متن کاملNitrapyrin addition mitigates nitrous oxide emissions and raises nitrogen use efficiency in plastic-film-mulched drip-fertigated cotton field
Nitrification inhibitors (NIs) have been used extensively to reduce nitrogen losses and increase crop nitrogen nutrition. However, information is still scant regarding the influence of NIs on nitrogen transformation, nitrous oxide (N2O) emission and nitrogen utilization in plastic-film-mulched calcareous soil under high frequency drip-fertigated condition. Therefore, a field trial was conducted...
متن کاملRoot-shoot regulation and yield of mulched drip irrigated maize on sandy soil
Sandy fields have been reclaimed to exploit the grain production potential in northwestChina. A 2-year statistically replicated field study was conducted to determine the effects ofmulched drip irrigation on soil water, soil nitrate, shoot root growth and yields of maize on asandy field in the Hetao irrigation district. Treatments included border irrigation (BI), fullymulched drip irrigation (F...
