The invention belongs to the field of rice cultivation, and particularly relates to a cultivation method suitable for no-
tillage rice in a fixed compartment of an oil
crop-medium rice field. The cultivation method comprises the following steps that: (1) rice seeds are coated by using dry-raised nurse, thick mud and dry fine soil serving as
coating agents, wherein the components comprise 7.9 to 12.5 percent of dry-raised nurse, 25 to 26.3 percent of rice seeds, 12.5 to 13.2 percent of thick mud with 37 percent of
water content and 50 to 52.6 percent of dry fine soil with 3 percent of
water content in percentage by
mass; the rice field is finished as required and the soil
moisture is kept; and keeping the
seedling age at 15 to 18 days; (2) the compartment width of the oil
crop field is 1.2 meters, the width of the
ditch is 0.3 meter, and the depth of the
ditch is 0.25 meter; the rape seedlings are applied to the field; a
ternary compound fertilizer of which pure nutrients comprise 15 percent of N, 15 percent of P2O5 and 15 percent of K2O is applied, and 30 kilograms of pure
nitrogen is applied in each mu; 5.80 kilograms of
zinc is applied in each mu; and 4.8 kilograms of
boron fertilizer is applied in each mu, and the
ditch is kept full of water; (3) rice seedlings with 50 to 100 grams of soil in each
seedling in 15 to 18 days are directionally thrown according to a
row space of 20 centimeters; and (4) the ditch is kept with water and the compartment surface has no water after throwing the seedlings till the heading stage, and dry and wet alternated cultivation is adopted from the
grain filling stage to the maturation stage. Compared with the conventional method, the yield is averagely increased by 8.7 percent.
