In early and late March, early-maturing tomatoes enter the fruiting period. At this time, the temperature management should be strengthened in the shed, which should be less than 30°C during the day and 15°C during the night to prevent flowering and fruit falling. When daytime temperature is above 20°C, ventilation should be strengthened. After mid-March, a small arch shed can be uncovered. When the height of the seedling is 30 centimeters, it is inserted into a frame (or hanging vine), and the vines are tied. After that, every 3 to 4 leaves are tied once. Single stalks were used for pruning, leaving 3 to 4 spikes per plant, 2 to 4 grains per panicle, and other shoots and flower buds were wiped off. Can be sprayed with 15 to 20 mg/L of 2,4-D fluid or 30 to 40 mg/L of anti-drop solution in the shed. Care should not be repeated when the flower is preserved and sprayed, and fruit should be sparsely covered after the fruit is settled. When the first fruit is stable, it is poured with water once, and then water is poured every 6-7 days. Watering should be done on a sunny morning. The next morning and noon should be promptly ventilated and drained. Hanging vine or plug before pouring rot manure 1500 kg, each ear began to expand, topdressing 15 kg of urea. Pay attention to the prevention and control of early blight, gray mold, virus disease and aphids.
