白洋淀是华北地区芦苇的重要产地,安新县苇田面积12.7万亩,年产值在4600万元以上。白洋淀芦苇素有皮白质优、产品经久耐用的美誉。但白洋淀干涸后的芦苇退化,导致产量下降,品质变劣。退化的芦苇植株变矮变细,平均株高不超过2.5米,茎部直径不到5毫米;提早干枯不能正常抽穗和落黄落叶,皮黄质硬。1986年调查,全县苇田严重退化约5～6万亩,减产约50%,经济损失2300万元。
Baiyangdian is an important origin of reeds in North China. Anxin County reed has an area of 127,000 mu with an annual output value of more than 46 million yuan. Baiyangdian reed prime skin white quality, durable products in the world. However, the reed degraded after Baiyangdian dried up, resulting in a decline in yield and deterioration in quality. Degraded reed plants become shorter and thinner with an average plant height of no more than 2.5 meters and stems less than 5 mm in diameter. Earlier dryness does not result in normal heading and falling yellow leaves, with hard yellow leather. 1986 survey, the county reed serious degradation of about 5 to 6 million mu, cut about 50%, economic losses of 23 million yuan.
