Method for transplanting seedlings by green sand culture machine

The invention relates to a method for transplanting seedlings by a green sand culture machine, and solves the technical difficulty of seedling transplanting by using the culture machine in the mechanized rice growing process on green sand soil. The method is characterized by comprising the following steps: 1) nutrition soil preparation: applying 25kg of 45% NPK fertilizer per acre at the arable period, and selecting green sand soil at the two sides of a seedbed field as nutrition soil according to a ratio of 1:6; 2) seedbed field preparation: using a green sand field with a seedbed and a big field according to a ratio of 1:80-100 as the seedbed field; 3) soil filling in a tray: placing at least 80% of acidity-adjustable green sand nutrition soil in the seedling raising tray; 4) planting: timely planting after the nutrition soil moist is fully wetted up, and scattering 20% of green sand nutrition soil over the seedling raising tray after planting; and 5) seedbed management: controlling the temperature of the s
