How to grow tomatoes in summer? Please describe the method to plant tomatoes in summer. Please refer to the following steps: 1. Variety selection summer tomato cultivation should choose heat resistance, aphid-resistant varieties, such as Maofen 802, Sukang 5, L402, Jiafen 15 and so on. 2. Cultivate strong seedlings and sow seedlings in the first half of May. Soak seeds with 1% potassium permanganate solution for 15 minutes before sowing, then soak seeds with clean water for 3~4 hours, wash seeds, dry water and sow seeds. Each mu of field needs seedbed about 10 square meters, seedbed width 1.2~1.5 meters, sprinkle appropriate amount of organic fertilizer, shallow hoe, fine aquilegia, irrigate horse water, sow after water infiltration, and then cover 0.5 cm of soil. Cover seeds are sieved on fine gardens, and 5 - 8 g of 50% carbendazim powder is mixed into the cover seed soil of each square meter of seedbed. Sowing grass cover moisture, arch and shade net rain cooling. Remove the straw after emergence, and cover the sunshade net around noon in sunny days. The seedlings are divided at the 3-leaf stage, about 40 square meters of seedbed are required for each mu of field, and the seedlings are planted at the 6-leaf stage, and the seedling age is 40~50 days. 3. High ridge planting, film net double cover field apply decomposed farm manure 4000 kg, decomposed cake fertilizer 50 kg, compound fertilizer 50 kg per mu. After soil preparation, 80 cm wide saddle-shaped high ridges and 30 cm wide furrows are planted. According to large row spacing 70 cm, small row spacing 40 cm planting, plant spacing 25~30 cm, about 4500 plants per mu. When planting, irrigate enough planting water, and cover fresh wheat seedlings in large rows after planting. Then set up a greenhouse frame, cover 0.06 mm thick film as a rainproof film on both sides to 40~50 cm from the ground for ventilation. Sunshade net to cool down around noon on sunny days. 4. Strengthen field management and irrigate seedling slowing water once after seedling slowing. Single pruning is adopted to remove the base branches when they grow to about 10 cm to promote root development, and the later branches are removed as soon as possible. Just in time to tie up the vine. Summer temperature is high, it is not easy to set fruit, when the flowers are half-opened, tomato Lingtu flowers are used to promote fruit setting, each plant leaves 3 ears of fruit, each ear leaves 3~4 fruits, and the upper part of the third ear leaves 2~3 leaves to top. When each panicle fruit begins to expand, urea 10~ 15kg and potassium dihydrogen phosphate 2~ 3kg are applied per mu in combination with watering. Water is usually poured once every 8 - 10 days. Remove the old and diseased leaves at the lower part in time. Spraying 0.3%~0.5% potassium dihydrogen phosphate solution or fertility treasure and other foliar fertilizers for 3~4 times in the middle and late stages to prevent premature aging. 5. To prevent and control aphids, spray 24.5% alfodin EC 1500~2000 times or imidacloprid 1000 times per mu. 75% chlorothalonil 600 times solution or 70% mancozeb 500 times solution was sprayed once every 10~15 days in the middle and late stages to prevent disease. The main diseases were Phytophthora blight, leaf mold and gray mold, which were controlled by spraying 600 times solution of 47% Garinone, 500 times solution of 50% Thiophanate-methyl and 1500 times solution of 50% Prochloraz respectively, once every 7~10 days and continuously for 3~4 times.
