1, plant pruning Cherry tomatoes are more commonly used double dry pruning, leaving the first inflorescence leaving one side branch, the remaining side branches removed. When you go to the side branch, wait until it grows to 6-8 cm in time. If the fork is crossed prematurely, it may cause premature plant failure; if the fork is too late, it may easily cause nutrient consumption and the plants are too long and affect fruit setting. During the annual cultivation in the solar greenhouse, the plants must be covered and discarded in time after being grown tall, and the withered and old leaves below the result branches are timely destroyed.
2, temperature management If it is winter and spring cultivation, the key is to prevent freezing seedlings early, and strive to slow seedlings as soon as possible, after planting 3 to 4 days is not ventilated, indoors during the day maintained at 30 °C, night temperature 18 °C ~ 20 °C. After easing the seedlings, the temperature is 20°C to 25°C during the day and 13°C to 15°C during the night. When the first inflorescence begins to flower, the indoor temperature is appropriately lowered to control vegetative growth, promote reproductive growth, and coordinate fruit and fruit relationships. In summer cultivation, it is necessary to pay attention to strengthening ventilation and prevent high temperatures from being prolonged.
3, fertilizer and water management 1 results before. Results The former colonization water must be thoroughly irrigated, combined with soil and plant growth potential to properly supplement the water and extend the water, and control the water in order to benefit the strong, especially when it is flowering, avoid pouring water, resulting in the phenomenon of falling flowers, the top dressing time is based on the plant The growth situation and the application of basal fertilizer were decided. If seedling growth is not good enough, it is necessary to topdressing nitrogenous fertilizer and combine with chasing a small amount of phosphorus and potassium fertilizers.
2 after fruiting. After the first fruit is seated, the seedlings should be finished in time, and the fertilizer should be watered in time to promote fruit development. Since then, topdressing should be dominated by phosphorus and potassium fertilizers, and nitrogen fertilizer should be minimized. Every 5 to 7 days depending on soil moisture and plant growth conditions, combined with topdressing, can also be appropriate to add potassium dihydrogen phosphate, potassium treasure and other foliar fertilizer. Watering should be even, not suddenly large or small, to avoid sudden changes in the soil wet, otherwise there will be empty fruit after cracking.
3 flowers. Cultivation in winter and spring must be made with a settee.
