The invention belongs to the field of
crop cultivating, and particularly discloses a rice
seedling cultivating technique for mechanical
transplanting. The rice
seedling cultivating technique comprises the following steps of selecting seeds; preparing
seedling cultivating soil; putting the seedling cultivating soil into a seedling tray to 80 percent of the capacity; uniformly distributing seeds to the seedling tray according to an amount of 62.5 mg-71.4mg per tray; covering the seedling cultivating soil onto the seeds, and maintaining the thickness to 0.4mm-1mm; horizontally placing the seedling tray in a rice field,
wetting the seedling cultivating soil, draining water, and covering a thin film, wherein the thin film comprises a film layer I and a film layer II, the film layer I is directly coated on the seedling tray, and the distance between the upper surface of the film layer II and the upper surface of the seedling cultivating soil is 18mm-25cm; maintaining the
wetting of the seedling cultivating soil in the seedling tray; when the seedling grows to 5cm, spraying a
plant root and stem growth
promoter once; preventing and curing the insects and the diseases one day before
transplanting. The rice seedling cultivating technique has the advantages that by adopting the method, the
germination time and the seedling emergence time can be shortened; the thickness of the seedling soil layer is uniform and consistent, the four corners of a rice block are vertical and square and are not lack of edges and corners, the seedlings are regular and uniform, the roots are intertwined, and the loosening is avoided after lifting.
