| 摘 要： | 试验利用免耕轻耙栽培有机水稻生产环境,通过设置鸭不同群体量水平,研究稻鸭共作对田间杂草群体的消长、田间害虫群落和天敌群落的影响。结果表明:稻田养鸭除草,体现在杂草群落的抑制上,是连续长期的过程,通过适宜的鸭群体量(15只/667m2),可以控制稻田杂草群体消长,实现水稻、杂草群落的生态平衡关系;稻鸭共作对稻田害虫群落的抑制作用低于化学药剂,且表现出明显的选择性;稻鸭共作对稻田害虫天敌群落具有一定影响,天敌群体降落程度有增加趋势,但无化学农药的毁灭性。

| Abstract: | The experiment was carried out to cultivate the production environment for organic rice by means of no-tillage and light harrow technology.Through setting different population level of duck,effect of the rice-duck farming technology on the weeds increment and reduction,pest insect communities in the field and natural enemy communities was studied.The results showed that controlling weeds by duck was a long-term and continuous process.The prosperity and perish of rice paddy weed can be controlled and the eco... |
