The invention discloses a cultivation method of mechanically transplanted rice seedlings. According to the method, first a
seedling raising field with an appropriate area is selected,
seedling raisingbeds are conducted in the
seedling raising field, and seedling plates are laid on the seedling raising beds, then soil which is fertile, and free of gravels, weeds and herbicide
pesticide residue isselected and uniformly mixed with decomposed
farmyard manure according to a certain volume ratio to produce a seedling raising substrate, the seedling raising substrate is spread onto the seedling plates, then the sterilized and germinated seed rice is sowed onto the seedling raising substrate, and a layer of seedling raising substrate is spread to cover the seed rice, finally covering is conducted with nets, during the
germination growth period of the seed rice, water and
fertilizer management and
disease and
insect pest management are strengthened until
transplanting, and a method of seedling plates in combination with dry raising is adopted for seedling raising, so that robust seedlings with a certain degree of
disease resistance are cultivated. The method has a high seedling emergencerate, and solves the problem that seedling raising operations of
greenhouse seedling raising are complicated, demands on the technical level of managing seedlings and farmer quality are high, cost ishigh, seedling raising without a shield and in the open is conducted, seedling emergence is not enough even, after
sowing, the situation of easiness of being destroyed by rain, easiness of being affected by mice and birds, etc. exists.
