绥棱县向阳水库有一位养鱼能手,他就是26岁的姜国福。他十分热爱养鱼工作,如饥似渴地学习新技术。1985年春,他反复思索着:“磁化水能使水稻增产,能不能促使种鱼早产卵呢?”经过深思熟虑,他决定用磁化水进行孵鲤的试验。他修建了四个试验池子:两个为磁化水池,总水面0.9亩;另两个为对照池,注入自然水,总水面1.23亩。 Suiling County Xiangyang Reservoir has a fish expert, he is 26 years old Jiang Guofu. He loves fish farming and hungering for new skills. In the spring of 1985, he repeatedly pondered: “Magnetized water can increase rice yield, can it be premature spawning?” After careful consideration, he decided to test hatching carp with magnetized water. He built four test ponds: two for the magnetized water tank, the total surface of 0.9 acres; the other two as a control pool, into the natural water, the total surface of 1.23 acres.
