step four, continuously rotating a third motor and a fifth motor in the n sub-tray paving modules to enable the seedling raising trays in the n seedling raising tray groups to respectively enter the transverse tray conveying devices in the n sub-tray paving modules;
step five, stopping the third motor and the fifth motor in the n sub tray paving modules, and rotating the fourth motors in the n sub tray paving modules to enable the seedling raising trays in the n seedling raising tray groups to enter the inclined plate under the pushing of the comb rack on one comb tooth base rod; after all the seedling raising trays leave the corresponding transverse tray conveying devices, all the fourth motors stop rotating; entering a sixth step;
if the distance between the seedling raising tray positioned at the lowest position on the inclined plate and the characteristic plane is larger than c, circularly executing the second step to the fifth step until the distance between the seedling raising tray positioned at the lowest position on the inclined plate and the characteristic plane is smaller than c; then entering a step seven; the characteristic plane is a plane which passes through the axis of the first transmission rotating shaft and is vertical to the outer side surface of the inclined plate, and c is equal to the distance between two adjacent comb tooth base rods;
otherwise, directly entering the step seven;
seventhly, the fourth motors in the n sub tray paving modules rotate to enable all the seedling raising trays on the inclined plate to move downwards in an inclined mode, and after the seedling raising tray located at the lowest position on the inclined plate is in contact with the field, the first motor and the second motor in the travelling mechanism rotate synchronously to enable the moving speed of the travelling mechanism to be equal to the moving speed of the second chain; entering the step eight;
step eight, after all the seedling raising trays on the inclined plate enter the field, synchronously stopping the first motor and the second motor in the advancing mechanism and the fourth motor in the inclined tray paving device;
if the length of the seedling raising tray which is not paved on the field is longer than the moving distance of the traveling mechanism in the step seven, the step two to the step seven are repeatedly executed;
if the length of the seedling raising tray which is not paved on the field is less than the moving distance of the traveling mechanism in the step seven and is more than the width of one seedling raising tray, repeating the step two to the step five a times and then executing the step seven once; a is the value obtained by dividing the length of the seedling raising tray which is not laid on the field by the width of the seedling raising tray and rounding downwards;
if the length of the seedling raising tray which is not paved on the field is less than the width of one seedling raising tray, the seedling raising tray paving is finished.
