Based on the experiment of different corn development stage (4, 6, 8 leaf stage) with different waterlogging days (5, 10, 15 days of ground water 10 cm below soil surface) treatments, a corn production function under waterlogging condition of paddy was established. The results showed the relative yield, relative dry matter weight of corn had a significant negative liner relationship with SEW and SDI to the soil watrlogging among the 3 leaf stages of corn. Combined with the relative yield indicators of corn, the SEW and SDI can be used as the index to assess the water-logging effect on the corn yield. Furthermore, it could also be used to give the critical value of water-logging days in the paddy field according to the relative yield requirement. %K 稻田 %K 玉米 %K 产量 %K 渍害指标 %K 受渍条件 %K 水分生产函数 %U http://www.alljournals.cn/get_abstract_url.aspx?pcid=03F54A49DE00578AA0E5DDF5BC021AA7&cid=298920A27C9BAA22346FCA384240FAA4&jid=466C05D88593309B3EB5CF34361E6426&aid=D4EC774E40D74879&yid=14E7EF987E4155E6&vid=DB817633AA4F79B9&iid=38B194292C032A66&sid=31125890FF093250&eid=381FB4265090A8E0&journal_id=1008-9209&journal_name=浙江大学学报(农业与生命科学版)&referenced_num=1&reference_num=4
