The method provided by the embodiment of the invention comprises the following steps: comparing the total number of the tomato plants planted in a seedling stage with the actual planting area of the tomato plants to obtain the initial planting density of the tomato plants; according to the daily average temperature and the daily average total radiation quantity of the tomato plants planted historically in the historical harvesting period, the daily average predicted temperature and the daily average predicted total radiation quantity of the tomato plants in the harvesting period are predicted; if yes, the theoretical planting density of the maximum tomato number can be increased by the multiple tomato plants under the daily average predicted temperature and the predicted total radiation quantity according to the daily average predicted total radiation quantity, if the theoretical planting density is larger than or equal to the initial planting density, lateral branches of the multiple tomato plants are reserved, and if the theoretical planting density is smaller than the initial planting density, the lateral branches of the multiple tomato plants are reserved. If yes, topping the tomato plants.
