稻田养鱼是指利用稻田的浅水环境辅以人为措施,既种稻又养鱼,以提高稻田生产效益的一种生产形式。稻田养鱼好处很多,不仅可以为社会增加水产品供应,使农民收入有明显增长,而且可以促进水稻增产,改善生态环境。 我国稻田养鱼具有悠久历史,在2000年前陕西的汉中、四川的成都已很盛行。目前,我国稻田养鱼有了新的发展和创新,赋予了新的内含,由过去传统的方式、依靠天然饵料养,发展到人工投饵养鱼;由平板式稻田粗放养鱼,逐步地形成了多种形式的稻田养鱼模式;从单纯稻田养鱼向养殖名特优方向发展。近几年我国稻田养鱼面积不断扩大,单产和效益不断提高。在许多农村地区,发展稻田养鱼已成为广大农民致富的一条重要门路。我国现有水稻田3.26亿亩,适于稻田养鱼的约1亿亩,目前实际利用的不到2000万亩,占可养面积不到五分之一,发展稻田养鱼具有很大的潜力。为了促进稻田养殖高新技术的推广,本刊将在介绍完稻田养鱼实用新技术之后,陆续向读者介绍稻田养殖河蟹、鳌、牛蛙、黄鳝等技术。
Paddy field fish farming refers to the use of shallow water environment supplemented by man-made measures, both rice and fish farming, in order to improve the efficiency of paddy production a form of production. The benefits of paddy fish farming are many, not only for the community to increase the supply of aquatic products, farmers have significantly increased income, but also can promote rice yield, improve the ecological environment. China has a long history of fish farming in paddy fields. Before 2000, Hanzhong in Shaanxi Province and Chengdu in Sichuan Province were very popular. At present, there is new development and innovation in paddy field fish farming in our country, which has given new implication. From the traditional way in the past, relying on the natural feeding of pigs and development to the artificial feeding of fish; Formed a variety of forms of paddy farming patterns; from purely rice farming to the direction of the development of special teeming. In recent years, the area of fish farming in rice paddies in our country has been continuously expanded, yields and benefits have been continuously increased. In many rural areas, the development of paddy fish farming has become an important gateway for farmers to get rich. There are 326 million mu of paddy fields in our country, which is about 100 million mu for paddy fish farming. Currently, less than 20 million mu are actually utilized, accounting for less than one-fifth of the raised area. The development of paddy fish has great potential . In order to promote the popularization of high-tech rice farming, this publication will be introduced after the paddy field fish farming practical new technology, one after another to introduce readers to rice farming crab, Ao, bullfrog, eel and other technologies.
