The invention discloses an eel-
toad-rice symbiotic cultivation method, and belongs to the technical field of agricultural compound cultivation. The eel-
toad-rice symbiotic cultivation method comprisesthe following steps: selection and arrangement of symbiotic cultivation unit fields; arrangement of a
toad escape prevention facility;
sowing of rice; preparation of juveniles in advance;
stocking ofjuveniles; placing
juvenile toads into a rice
sowing area and controlling the throwing density of the
juvenile toad; feeding; breeding of earthworms; topdressing of rice fields; adjustment of
water quality and
water level;
pest control; and catching-up. Diseases and
insect pests on land and air are prevented and controlled, and poisonous and harmful pesticides are avoided; chemical fertilizers are avoided, and
soil protection is facilitated; the method is beneficial to guarantee that
fertilizer and water do not flow outwards and non-
point source pollution can be avoided effectively; the
wetland function of the rice fields is well enhanced; emissions of
greenhouse gases such as
methane are reduced; eels, toads and rice are bred in a
symbiosis manner and are beneficial to one another, organic matters such as
nitrogen and
phosphorus which are generated by the eel and toad can be absorbed by the rice and promote the growth of the rice, and the
pollution of the
nitrogen and the phosphorusto the
water body is reduced; and the purification effect of the rice on the
water quality can provide a high-quality growing
water environment for the eels.
