摘要： 本文通过对黄河三角洲地区山东省无棣县38年气象资料和苜蓿适宜收获物候期分析,评价该地区苜蓿收获时期的生态气候适宜性。结果表明,黄河三角洲地区第一茬苜蓿(5月10~25日)和第三茬(9月末~10月初)前着刈割晒制干草是完全可以成功的,第二茬(7月15~30日)苜蓿很难刈割晒制干草。

Abstract: Analyze the climatic suitability of growing period for alfalfa harvested and meteorological data with thirty-eight years in Wudi County located in the region of Yellow River delta, Shandong Province, the eco-climatic suitability for alfalfa harvested period in that region were evaluated. The results showed as follows:It is very suitable for alfalfa cutting and suncuring in the first cutting(May 10~25)and the third cutting(last day of September and the first day of October), but no the second(July, 15~30).
