The invention belongs to the technical field of rice planting, and discloses an early rice
seedling slinging cultivation method after full returning of triple-
cropping rape
straw. The method comprisesthe following steps: soaking seeds with a
prochloraz liquid
medicine or hymexazol, cleaning and soaking the seeds with clear water; applying a decomposed
organic fertilizer and a
ternary compound fertilizer as base fertilizers before the rice field is ploughed, and ploughing and raking the rice field with water; performing furrowing before
sowing, and digging surrounding ditches around; determining a seeding time for seeding according to previous harvesting condition of rape and a suitable
seedling transplanting age; conducting film mulching and heat preservation after
sowing, and conductingseedling hardening after three leaves and one core; field preparation: after the oilseed rape is mature, timely combining the oilseed rape with mechanical harvesting, crushing
straw, returning full amount to the field, performing shallow
water irrigation, and performing rotary
tillage after next-day base
fertilizer application; and performing
fertilizer application after
seedling slinging.
Lime isapplied at the same time to improve the field environment,
normal growth of early rice in the later period is not affected, burning or abandoning of preceding
crop straw in the field is reduced, thefertilizing amount and method after oilseed rape straw is returned to the field are optimized, time and labor are saved, the beneficial effect of being
environmentally friendly is achieved, the environment is not polluted, and body health of people is protected.
