The invention discloses a pelleting
coating method suitable for tomato seeds. The pelleting
coating method comprises the following steps: step 1, seed pretreatment; 2, a
nucleation stage; 3, an enlarging stage; 4, a rolling stage; 5, a coloring agent and talcum
powder are added, and the surfaces of the
pellets are
colored uniformly at the low rotating speed of 6-10 r / min; and 6,
drying at 30-40 DEG C for 45-75 minutes until the
water content of the
pellets is less than or equal to 8%. According to the pelleting
coating method for
processing the tomato seeds,
pesticide,
fertilizer, a
plant regulator, a
water storage agent, an
oxygen producer and some auxiliary materials can be orderly coated on the tomato seeds in a layered mode, the small tomato seeds can be amplified by dozens to hundreds of times through pelleting
granulation,
plant protection before
sowing can be effectively achieved, field application with the
fertilizer and the
pesticide can be achieved, and the application range is wide. The purposes of protecting and strengthening seedlings and regulating
plant growth are achieved, and favorable conditions are created for mechanical precision seeding, so that the purposes of saving a large amount of seeds, improving the yield and saving the cost are achieved.
