| 摘 要： | 稻萍鸭生态系统是一种稻田养萍、养鸭,互促共生、生态环保、有机高效的栽培模式,是一项集有机稻米生产与水禽共养于一体的生态型农业清洁生产模式.稻萍鸭生态系统的主要生态效应有:一是抑制稻田杂草的发生和危害,控制效果达95%以上,其对阔叶杂草控制效果最好,对双子叶和单子叶杂草控制效果良好.二是压低害虫基数,减轻害虫发生和危害,其对稻飞虱等虫害的控制效果较好.三是控制水稻病害,尤其是水稻纹枯病得到有效控制.四是改良土壤,表现为土壤养分库数量有不同程度的增加,土壤结构有较好的改善,土壤环境条件得到明显的改善,有利于水稻对养分的吸收.五是刺激作用,在稻鸭共作的效果中,由于鸭的活动刺激了水稻生长.

| Abstract: | Rice-Azolla-Duck ecosystem is a intergrowth and ecology environment and organic high effect growth mode that paddy field growth azolla and duck. It also is a ecotype agriculture cleanness production mode for organic rice production with water fowl. The mostly ecology effect of Rice-Azolla-Duck ecosystem: First, restrain paddy field weed growth and harm, the control efficiency more than 95%,the broad-leaved weed had the best control, the dicots and monocots weed had effective control. The second is to suppress pest base, reduce the occurrence of pests and hazards, the plant hopper pest had effective control. Third, control of rice diseases, in particular, the effective control of rice sheath blight. Fourth, improve the soil, the number of soil nutrient pool have different degrees of increase, soil structure had effective improvement, soil environment conditions are significantly improved, rice is conducive to the absorption of nutrients. Fifth, stimulus effective, in the rice-duck interact effective, it is duck''s activities to stimulate the growth of rice. |
