根据山西省霍泉灌区李堡试验区 1 996年 1 0月～ 1 999年 9月 3年的试验资料 ,分析建立了冬小麦与夏玉米的耗水量估算模型及产量与水分关系的数学模型 ;以 1 998年 1 0月～ 1 999年 9月冬小麦、夏玉米连作为例 ,对两种作物的需水规律进行了分析 ,并利用所建模型 ,分析给出了冬小麦、夏玉米连作套种的高产节水灌溉定额。最后用动态规划法分析提出了有限水量在作物生育期内的最优分配方案
According to the experimental data of Li Bao Experimental Area, Huoquan Irrigation District, Shanxi Province, China from January 1996 to September 1999 for three years, the mathematical models for estimating the water consumption of winter wheat and summer maize and the relationship between yield and moisture were established. From January 1998 to September 1999, winter wheat and summer maize were taken as an example to analyze the water requirement of the two crops. The model was used to analyze the yield of winter wheat and summer maize continuous cropping intercropping Water saving irrigation quota. Finally, the dynamic planning method is used to analyze the optimal distribution plan of limited water during crop growth period
