1, suitable density: the planting density should not be too large, the row spacing of early-maturing cultivation should be 60 cm× 40 cm, and about 2800 plants should be planted per mu, leaving 3-4 ears, and then topping; Long-term cultivation, row spacing of 70 cm× 50 cm, planting about 1900 plants per mu. After leaving 6-8 flower heads, change the tips.
2. Fruits per ear: The number of fruits per ear depends on the size of the fruits. Varieties with single fruit weight of 80- 100g (fruit diameter of 4.5-5.5cm) have 7-8 fruits per ear; Single fruit weight 100- 120g (fruit diameter 5.5-7cm) with 6 fruits per ear; For varieties whose single fruit is larger than 120g (fruit diameter is 7 cm), 4-5 fruits are left per ear. After the fruit is set, the abnormal fruit and too small fruit should be eliminated in time.
3. Single stem pruning: Because the fruit of tomato string stays on the plant for a long time, the canopy of the plant is required to have good light transmittance and sufficient photosynthetic leaves. Don't destroy the lower leaves of each ear before harvesting.
4. Sufficient fertilizer and water: there are many fruits left in a single tomato, so special attention should be paid to fertilizer and water management. Plantar fertilizer should be applied before planting, and topdressing should be done in time after fruit setting. Water 1 time every week during the fruit expansion period, and topdressing once every 2-3 weeks. Watering should be done on a sunny morning. Pay attention to the application of potassium and calcium to prevent gluten rot and umbilical rot.
5. Promote fruit setting: Use PCPA (p-chlorophenoxyacetic acid) to dip flowers to protect fruits, or use electric vibrator to artificially assist pollination to promote fruit setting.
6. Harvesting and transportation: whole ear harvesting. After the last fruit of each ear enters the discoloration period, the ear is cut off at the base of the ear with scissors, covered with plastic bags with small holes, and packed into cartons or plastic boxes for transportation.
