大米草对海盐生产的影响及其防治对策

江苏海盐产区从20世纪从90年代开始进行了一系列改制,改革尝试,其中大米草的引进栽培也是一项大事。现在的银宝公司(简称"公司")直辖的三大盐场都在最大范围内,尽最大能力进行了移栽,广泛的纳潮、送水、排淡沟渠、储水的水库、更有生产单元的蒸发池都移栽了大米草,然而,大米草对海盐生产没带来一丁点好处,带来的是送、排沟渠的整治投入,整治的方法远远不及大米草的生长漫延的速度,迫使盐滩产盐面积大幅度减少。原有的蒸发基本上全部变成了养殖池塘,但大米草并没有停止它漫延的脚步和速度,现在有限的产盐面积又有1/5的面积被占。根据公司"十二五"规划要做强做优盐业,建设高效原盐生产基地,对大米草的防治应引起高度的重视。

Influence of Spartina Anglica to Sea Salt Production and the Controlling Measures

It is well known that some reforms are tried in the sea salt area of Yinbao Corporation in 1990s.To fetch and plant spartina anglica is a great incident at that time.And now spartina anglica are planted in the three salt fields of Yinbao Corporation including the reservoir and the evaporation ponds.However,it is no use to improve the sea salt quantity to do this.The evaporation area of salt production decreased largely because of the rapid growth of spartina anglica and the low progress of maintaining canal.The evaporation ponds are becoming the cultivation ponds.Spartina anglica are still expanding now and one fifth of evaporation area of salt production is inhabited by them.According to the company’s ’the Twelfth-Five Plan’,we should be the great and excellent corporation and set up the production base of salt.So it should be highlighted to prevent and control the growth of spartina anglica.
