利用鲤鱼在水田除草,已引起人们关注。这对节省劳力、减少除草剂开支、降低成本开拓了新途径。去年日本科学家曾做过试验:在约3.7公亩与约1公亩的两块水田里,在插秧后的6月下旬,将170尾与61尾体长15厘米的鲤鱼分别放入两块试验水田。大块水田基本上到7月底就让鲤鱼游起来,小块水田到8月底也能让鲤鱼漫游起来,试验人员说:“以鲤鱼除草,也可改善生态环境,效果良好。” The use of carp in the paddy field weeding, has drawn people’s attention. This opens up new avenues for saving labor, reducing herbicide costs and reducing costs. Last year, Japanese scientists had conducted experiments: In two paddy fields of about 3.7 and about 1 acre, in late June after planting, 170 carps and 61 carp, 15 cm in length, were placed in two separate trials Paddy field. The large paddy fields basically let the carp swim by the end of July. Small paddy fields can also make the carp roam up by the end of August. The trial staff said: “Weeding the carp can also improve the ecological environment and work well.”
