The invention belongs to the technical field of rice and shrimp planting and breeding, and discloses a rice planting method for a shrimp and rice symbiosis field. A new rice variety 'giant rice' moresuitable for cultivation in the shrimp and rice field is selected, seeding is performed in mid-to-late May, transplantation is performed at the end of June, shrimps and rice are harvested in the lastten-day of September, seedlings are transplanted to 60-75 hundred holes per hm<2>, and the transplanting seedling number of unit area is 1 / 3 of the practical level of large area at present. An irrigation layer at a reviving tillering stage is 10cm-20cm, the field can be exposed for 3-5 days after reaching preset total number of seedlings, a deep irrigation layer at an effective tillering termination stage, a jointing-booting stage and a filling and ripening stage is 40cm-50cm, and the depth of the irrigation layer of the shrimp and rice field is increased by 20cm-30cm at middle and later stages of rice growth. Weeds are pressed by the seedlings, chemical weeding is omitted, topdressing is performed in a low-intensity and high-frequency manner, and nitrogen fertilizers, tillering fertilizers and ear granule fertilizers are applied for 2-3 times according to field seedling condition quantity demanded. Mutualistic symbiosis of the rice and the shrimps is realized, and yield, quality and benefits are synchronously improved.
