| 摘 要： | 作物系数和需水量是制定作物灌溉制度和计算水资源平衡的重要参数,不同气候和栽培条件下作物系数和需水量会发生变化,试验旨在明确鲁北地区麦秸盖田对夏玉米作物系数和需水量的影响。通过大田试验以水量平衡法计算作物需水量,以Penman-Monteith公式计算参照作物蒸散量和作物系数。结果表明麦秸盖田比露地栽培生育期内作物需水量减少30.4 mm,作物系数降低7.2%,水分利用效率增加21.0%。

| Abstract: | Crop water supply(CWS),crop coefficient(CC) and water using efficiency(WUE) are the basic parameters for establishing irrigation schedule and calculating water resources balance,which are changeable under different climate and cultivation,the aim of this experiment is to clearly understand the effects of mulching farm of wheat straw on CWS,CC and WUE of the summer corn in north of Shandong Province.Based on field experiments,CWS is calculated by water balance equation and the reference crop evapotranspirati... |
