稻鸭生态种养技术,是指在稻田抛栽水稻后放养一定数量野生性强的鸭子,在不施用化学农药的情况下,利用水稻抗性、稻田有益生物、生物农药等控制稻田有害生物的危害,实现稻鸭双丰收。实践证明,该技术简单易行,效果十分明显。对稻飞虱的控制率在95%以上,杂草的控制率100%,二化螟、纵卷叶螟、纹枯病的控制率在70%左右。大大减少了化学农药的施用量,改善了农业生态环境。由于鸭子的活动、觅食和排泄,既增加了水稻所需的肥料,又促进了水稻根系的生长。据统计,采用这一技术每公顷增收2400元左右。本刊特邀桃江县农业局高级农艺师苏伟同志绘制、农艺师陈敏同志改编,用连环画的形式就这一技术作详细介绍。
The technology of rice-duck ecological planting refers to the stocking of a certain number of wild-type ducks after throwing rice in the paddy field, and controlling the pest of rice paddy by using rice resistance, beneficial rice paddy, biological pesticide and the like without applying chemical pesticides Harm to achieve double harvest of rice and duck. Practice has proved that the technology is simple and easy, the effect is very obvious. The control rate of planthoppers is more than 95% and the control rate of weeds is 100%. The control rate of rice stem borers, leafroller and leaf blight is about 70%. Greatly reducing the application of chemical pesticides and improving the agricultural ecological environment. Due to duck activities, feeding and excretion, it not only increases the fertilizers needed for rice but also promotes the growth of rice roots. According to statistics, using this technology an increase of 2,400 yuan per hectare. In this article, we invited Comrade Su Wei, a senior agronomist from Peach County Bureau of Agriculture, to make an introduction to this technique in the form of a comic book.
