利用稻田养殖泥鳅,具有投资少、见效快、效益高的特点。余杭市农科所于1998年进行稻田养殖泥鳅试验,4月18日亩放养泥鳅苗50公斤,到当年11月18日收获时,每条泥鳅长达10厘米左右,泥鳅亩产达391.5公斤;早稻亩产为368公斤,晚稻亩产为402公斤,获得了粮食和经济效益的双丰收。现将泥鳅稻田养殖技术介绍如下。1.生活习性泥鳅多生活在淡水或湿润环境中,适应中性或弱酸性的水质或底质。泥鳅对水温的适应范围为15~30℃,最适水温24~27℃,当水温低于5~
The use of loach farming rice, with less investment, quick, high efficiency. In 1998, Yuhang Agricultural Research Institute experimented on loach farming in paddy fields. On April 18, 50 kg of loach seedlings were planted in mu on the 18th of that year. When loach was collected on November 18 of the same year, each loach was about 10 centimeters long and its yield reached 391.5 kg. The output of early rice is 368 kg per mu and that of late rice is 402 kg per mu, achieving double harvest of food and economic benefits. Now loach rice farming techniques are as follows. 1. Life habit Loach live in fresh water or humid environment, to adapt to neutral or weak acid water or sediment. Loach adapt to the water temperature range of 15 ~ 30 ℃, the optimum temperature of 24 ~ 27 ℃, when the water temperature is below 5 ~
