江苏滨海盐土稻田养鱼生态、经济效应初报

Ecological and Economic Effects of Fish-farming in Paddy Field of Coastal Saline Soil Regions of Jiangsu Province.

滨海盐土采用引淡、放萍、种稻虽有改土增产作用,但绿萍越冬、春繁花工多,成本高,推广有一定困难。为此,我们在江苏如东棉花原种场进行了稻田养鱼试验,拟奏“鱼稻共生,粮鱼增产,改土培肥”之效。一、试验方法本试验采取大区对比与大田调查相结合的方法进行。1985年在原种场2-6-8及2-6-9两田块进行稻田养鱼(共0.8ha),以相邻未养鱼2-6-5及2-6-6两块田作对照(亦0.8ha)。1986年又扩大进行稻田养鱼生产试验,共计3ha,

The methods of plot control and field survey are used in studying the ecological and economic effects of fish farming in paddy fields of coastal regions of Rudong county of Jiangsu province. The results showed that fish farming in paddy fields could not only ameliorate saline soil efficiently, but also reduce weeds and pests in the field. It provides a valuable information for saline soil amelioration and fish and rice cultivation in the coastal region.
