Abstract
Fish-rice symbiosis is a kind of green and healthy breeding mode which combines planting and breeding.It is an important technical measure to develop ecological agriculture and improve the comprehensive benefit of pond.In order to explore a symbiotic model combining fishery and planting,a experiment of the rice planting in fish pond was carried out in the southern foot of the Qinling Mountains in 2022.After four months of breeding and planting,the comparative experiment was successful.The results showed that the fish-rice symbiosis model was a new type of agricultural production activity by using aquaculture ponds to grow rice,which can stabilize the aquacul-ture area of fish ponds and expand the planting area of rice.The fish yield increased by 11.4%and the incidence of fish decreased by 31.0%,comprehensive economic benefit increased by 19.2%.In addition,the water quality im-provement effect was significant,and the ammonia nitrogen and nitrite in the test pond were significantly lower than those in the control pond(P<0.05).This model could not only achieve rice and fish harvest,but also provides technical reference for pond ecological efficient aquaculture,ecological treatment of aquaculture tail water and im-provement of fishery quality and efficiency.关键词
