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.
