摘要
根据中国科学院禹城综合试验站蒸渗仪所测的作物耗水量资料，简要分析了山东省禹城市冬小麦、夏玉米的耗水量及其耗水过程。该市冬小麦平均耗水量为４８２．２ｍｍ，水分利用率为１１．０１ｋｇ／（ｈｍ２ｍｍ）；夏玉米平均耗水量为３９８．９ｍｍ，水分利用率为１９．７９ｋｇ／（ｈｍ２ｍｍ）。文中还研究了公顷单产为６０００ｋｇ的冬小麦、公顷单产为９０００ｋｇ的夏玉米的高产灌溉制度及其管理。该市冬小麦高产灌溉定额为３６０ｍｍ，应灌播前或越冬水，返青或起身水、拔节水、抽穗水和灌浆水；夏玉米高产灌溉定额为１５０ｍｍ，应灌苗期水、开花水和灌浆水。
According to experimental data on the water consumption of crop measured by lysimeter at Yucheng Experimental Station, Chinese Academy of Sciences, the water consumptions and the waterconsumpting processes of winter wheat and summer maize were respectively analyzed.The water consumption of crop was 482.2 mm for winter wheat and 398.9 mm for summer maize. The water use efficiency was 11.01 kg·(hm2·mm)-1 for winter wheat and 19.79 kg·(hm2·mm)-1 for summer maize in Yucheng City. The schedules and managements of irrigation in the highyielding cultivation of winter wheat and summer maize were studied. The yield is 6000 kg/hm2 for winter wheat, and 9000 kg/hm2 for summer maize respectively.The highyielding irrigating quota is 360 mm for winter wheat and 150 mm for summer maize. The irrigation periods are overwintering, greenturning, jointing, heading and milking for winter wheat and emergence, flowering and milking for summer maize.
