为了进一步促进农业产业结构调整,增加农民收入,现向大家介绍一种河藕与鱼虾蟹生态种养的高效模式,供有关农户在结构调整时参考: 生态种养的好处:(1)河藕池中有许多底栖动物、水生昆虫、小型软体动物、甲壳动物以及许多浮游动物,还有各种水生植物,资源十分丰富,可用来发展鱼虾蟹混养。(2)藕田混养鱼虾蟹可大大减少投饵量,能降低成本,增加效益。(3)实行多元复合结构立体开发不但能充分利用水面资源,同时还能使池塘的自然生态环境发挥作用,促进鱼虾蟹健康生长,减少疾病,从而使池塘收入提高2至3倍。根据专家学者对如东县岔河镇长桥村13组养殖户李建国,凤凰村8组花建明等5个种养殖户的调查结果,一般每亩可生产河藕3000至4000斤,产鱼100斤,
In order to further promote the adjustment of agricultural structure and increase the incomes of farmers, we will now introduce a highly efficient model for ecological planting of river and fish, shrimp and crabs. Reference is made to the relevant farmers for their readjustment: Benefits of ecological planting and breeding: (1) River Lotus pond in many benthic animals, aquatic insects, molluscs, crustaceans and many zooplankton, as well as a variety of aquatic plants, is very rich in resources, can be used to develop fish and crab polyculture. (2) Outian polyculture fish and shrimp can greatly reduce the amount of feeding, can reduce costs and increase efficiency. (3) Three-dimensional development of multi-component composite structure will not only make full use of water resources, but also make the pond natural ecological environment play a role in promoting the healthy growth of fish and shrimp and crabs and reducing diseases, thus increasing pond income by 2 to 3 times. According to the survey results of 5 breeding farmers such as Li Jianguo of 13 groups in Changqiao Village of Chahe Town in Rudong County and Huajianming Group of 8 groups of Fenghuang Village, experts and scholars generally can produce 3000-4000 pounds of river lotus per acre and fish 100 jin,
