Planting tomatoes is a good way for farmers to get rich, and strengthening the management of tomato growth period is the key to high yield and high efficiency. Grasping the growth period management includes cultivating weeding, storing water and protecting weeds, tying vines, pruning and removing old leaves. , ventilation and light transmission, strengthen prevention and control of pests and diseases, strengthen temperature management and other measures, today to introduce the field management technology of tomatoes.
Â
 Field management techniques for tomatoes:
Â
1. Grasp the management of the growth period. Including cultivating and weeding, water storage and protection, tying vines, pruning, removing old leaves, ventilating and lightening, strengthening pest control, and strengthening temperature management. Among them, the diseases of tomatoes mainly include viral diseases, bacterial wilt, early blight, late blight, etc.; insect pests mainly include cotton bollworm and aphids. The disease of tomatoes can be prevented from being refractory, and should be based on "prevention". The prevention and treatment methods of viral diseases include: selection of disease-resistant varieties, seed disinfection, planting of alfalfa, control of aphids, and early planting. Temperature management is to increase the ventilation of the shed during the day, so that the temperature inside the shed is maintained at around 25 °C. The night temperature is maintained between 10-13 °C. When the wind starts to be released, the air outlet should be small to large, from small to large. After the temperature drops in the afternoon, the air outlet will gradually become smaller or closed.
Â
2. Grasp the management of fertilizer and water. The growth period of tomatoes generally does not require watering in the summer and autumn rainy seasons, but when the second to third ear fruits are ripe, they should be properly watered. According to the growth of tomato plants, timely topdressing to promote fruit development, preserve flowers and preserve fruit.
Â
3, picking fruit at the right time. The tomatoes matured in four stages: green ripe, discolored, mature and mature. Storage and preservation can be harvested during the green ripening period. Transport for sale can be picked during the color change period (1/3 of the fruit turns red). On-site sale or self-sufficiency should be picked at maturity when the fruit is reddened at more than 1/3. It should be lightly picked and harvested when harvesting. It is best not to bring fruit stalks when picking up, in case the fruits are stabbed in each other during shipment. Before the first frost, if there are still unripe green fruits, they should be stored in the greenhouse after harvesting, and then listed after the fruit becomes ripe, which not only prolongs the supply period, but also increases the economic benefits.
Â
Tomato field management technology is introduced here. It is not suitable to use hormones to stimulate fruit coloring after fruit ripening. After selection and packaging, it has the advantages of reducing production cost, improving fruit quality and ensuring consumers. Safe to eat.
