【摘要】 在黑龙江省查哈阳灌区2006年实测数据的基础上,建立了4种水分生产函数模型,经过对4种水分生产函数模型的分析,确定出适合查哈阳灌区的水稻水分生产函数模型为Jensen模型,再次验证了Jensen模型的广泛适用性,为该地区水稻非充分灌溉条件下的灌溉制度优化提供了基础依据。更多还原

【Abstract】 Based on the experimental data of 2006 in Chahayang irrigation area of Heilongjiang Province,water production function models were established.Through the analysis to the four models,the Jensen model was regarded as the most suitable model for Chahayang irrigation area.The experimental result provides a scientific basis for optimum irrigation schedules of rice under the deficient irrigation of this area.更多还原
