1. Watering. If you water enough water for planting, you don't need to water again until the first ear inflorescence blooms and sets fruit. If there is little water for planting, you can ditch and pour small water in the border, and choose a sunny morning to do it. Water for the first time after the first flower sets fruit, the result period requires a large amount of water, watering once every 5-6 days, it is required to see dry and wet. Reduce watering during harvest to prevent fruit cracking.

2. Top dressing. After the first ear flower sets fruit, combined with watering, apply 10 kg NPK compound fertilizer per mu. When the first ear fruit turns color, 10 kg compound fertilizer per mu is applied to promote fruit development. Afterwards, topdressing is once every two ears appear. , The amount of top dressing is 10 kilograms of compound fertilizer per mu.

3. Temperature management. The cultivation temperature in the protected field is higher than that of ordinary tomatoes. The temperature is above 10℃ at night, 20-25℃ during the day, and the highest is not higher than 35℃.

4. Pruning. Cherry tomato plants are tall and poorly erect. When the plants grow to 50 cm, they are inserted into the rack to prevent lodging. The growth of side branches is strong. Generally, double-stem pruning is performed, leaving 2 strong branches first, and the others are erased. Generally, it is not topped, and when the lower old leaves turn yellow, they are removed in time to reduce nutrient consumption.

5. Thin flowers and preserve fruits. In early spring, when the temperature is low, pollination is not good and the flowers are easy to fall. Use 2,4-D to smear the newly opened calyx and flower stalk. Cherry tomatoes have more flowering and fruit per ear. Choose 20-30 fruits with good fruit setting, and discard the rest.
