一、湖北稻田生态系统分析湖北地处中原,地形复杂、植被丰富、土地肥沃、具有北亚热带季风气候,一年四季分明。在水稻生长季节,温度适宜,雨量充沛。水稻栽培制度复杂、单双季稻混栽面积大。冬季低温时间短,无霜期比较长,既有利水稻生长,也为害虫的发生,繁殖为害创造了有利的条件。 First, Hubei paddy ecosystem analysis Hubei is located in the Central Plains, the terrain is complex, rich vegetation, fertile land, with a north subtropical monsoon climate, clear throughout the year. In the rice growing season, the temperature is suitable, abundant rainfall. Rice cultivation system is complex, single double cropping mixed planting area. Winter low temperature time is short, frost-free period is longer, not only beneficial to the growth of rice, but also for the occurrence of pests, reproduction and damage created favorable conditions.
