How to grow cherry tomatoes?

How to grow cherry tomatoes? Cherry tomatoes can be planted like this: Cherry tomatoes are temperature-loving vegetables, the temperature needed for their growth and development is higher than that of ordinary tomatoes, the optimum temperature for seed germination is 25-30 ℃, the optimum temperature for growth is 20-25 ℃, and the optimum temperature for fruiting period is 15-25 ℃. Like light, lack of light, serious flower and fruit drop; less water in the early stage, more in the later stage; strong adaptability to soil, the best performance in sandy loam soil, like potash fertilizer, at the same time, in order to prevent the occurrence of navel rot, calcium fertilizer should be applied properly. The yield of cherry tomato is relatively low, with a yield of 6-1500 kg per mu, but the sales price is higher. The main varieties are Virgin, Lingqiu, Cherry Red and so on. 1. Cultivation season: the cultivation season of cherry tomato is similar to that of ordinary tomato. For open field cultivation, spring sowing can raise seedlings in the protected field in February, plant after the final frost in late April, and enter the harvest period in the middle and late June. Autumn sowing can raise seedlings in July, plant in August, and start harvesting in October. Cultivation in protected areas can be appropriately early or delayed. two。 Nursery bed preparation: the nursery bed should be selected in the plot where the eggplant vegetables have not been planted, the fertile fields should be mixed with 40-50% mature organic fertilizer, 1 kg of superphosphate and 5-10 kg of plant ash should be mixed in each nutrient soil, sifted and dried on the nursery bed. The seedling bed should be set in the greenhouse in early spring, the electric hotline should be laid if the temperature is too low, and the seedling bed should be set in a cool and ventilated place in summer. There are many Rain Water in summer, the nursery bed should have rain shelter facilities, and the bed end should have drains. 3. Tomato seed treatment before sowing: in order to increase the yield and income of tomato, the seeds must be treated before sowing. Cherry tomato diseases are mostly spread by seeds, so seeds should be disinfected before sowing. In order to prevent and cure the occurrence of virus disease, trisodium phosphate is often used in production. The method is as follows: first, wet the seeds with clean water, wrap them with gauze, soak them in 10% trisodium phosphate solution for 15-20 minutes, take out the seed bags, wrap them with warm towels and put them at 28 ℃ to accelerate germination. During the period of germination, the seeds were washed once a day, and the seeds could be sown when the seeds were white in about 3-4 days. 4. Seedling management: heat preservation should be paid attention to in early spring, and the ground temperature of seedling bed should be controlled at 25-30 ℃ before emergence. Summer seedlings should be protected from rain and cooled down. When most of the seeds emerge, the temperature should be cooled in time, and the temperature should be controlled at 20 ℃ in the day and 12-15 ℃ at night when the seedlings grow two true leaves. 5. Seedling division: the temperature in early spring is getting higher and higher, and the seedling bed generally does not need a floor hotline. Early spring seedling should be carried out in sunny morning, using the method of dark water planting, first open a ditch, and then watering, wait for the water to seep down, release the seedling and bury the soil. After being buried, there is no muddy water on the surface. The row spacing is 10 × 10 cm. Summer seedling separation is carried out in the evening or cloudy days, the method is the same as that in early spring. The row spacing is 10 × 10 cm. Irrigation after planting, sunshade on the border, remove the mulch after slowing down the seedlings. The temperature of seedling separation bed was 25-28 ℃ in daytime and 15-18 ℃ in night before seedling retardation, and 20-25 ℃ in daytime and 13-15 ℃ in night after seedling retardation. It is not watered in early spring, and the seedbed is often watered in summer. The seedlings were planted when they reached 8 true leaves. 6. Planting: first soil preparation, combined with deep ploughing, 5000 kg of rotten organic fertilizer, 20 kg of N, P, K ternary compound fertilizer and 20 kg of superphosphate per mu. After leveling the ground, make a flat bed 150 cm wide (if you buckle plastic film in early spring, you will do 10 cm high, 50-60 cm wide). The flat beds were planted in 3 rows, and the small and high beds were planted in 1 row. The distance between plants is 20-30 cm and 4500-6000 plants per mu. Buckle the plastic film to cover the whole border first, and then set the planting hole according to the plant distance, and the planting depth is 1 cm from the cotyledon to the ground. 7. Field management: 7.1 watering. If you pour enough planting water, you don't need to water the first inflorescence to blossom and set fruit. If the planting water is less, it can be ditched in the border and carried out in the morning on a sunny day. The first panicle flower was watered with water for the first time after setting fruit, which required a large amount of water in the fruiting period, watering every 5-6 days. To reduce watering during the harvest period to prevent fruit cracking. 7.2 topdressing. After the first ear flower set fruit, combined with watering, the N, P and K compound fertilizer was applied 10 kg per mu, and when the first ear fruit changed color, 10 kg compound fertilizer per mu was applied to promote the fruit development. after that, the topdressing amount was 10 kg per mu for every two panicles. 7.3 temperature management. The temperature of protected cultivation is higher than that of ordinary tomatoes, which is more than 10 ℃ at night, 20-25 ℃ in daytime, and the highest is not more than 35 ℃. 7.4 pruning. The cherry tomato plant is tall and erect, and it is inserted into a rack when the plant grows to 50 cm to prevent lodging. Lateral branches have strong growth power, generally double-stem pruning, leaving 2 strong branches first, and erasing the others. Generally do not hit the top, when the lower old leaves yellowed off in time to reduce nutrient consumption. 7.5 thinning flowers and protecting fruit. When the temperature is low in early spring, poor pollination can be used to smear the newly opened calyx and stalk (only once). Cherry tomatoes blossom and bear more fruits per panicle. 20-30 fruits with good fruit setting are selected, and the rest are removed. 8. Harvest: harvest when fully mature, and retain sepals and a stalk when harvesting. 9. Pest control: common diseases are early blight, late blight, virus disease, Botrytis cinerea and so on. Control method: rotation with non-Solanaceae crops for 3-4 years. At the initial stage of the disease, 70% mancozeb 500 times solution and 75% chlorothalonil 600 times solution were used, once every 7-10 days, and 4-5 times continuously. Insect pests are mainly aphids, which can be controlled by 2000-3000 times of 20% fenvalerate EC and 2000-3000 times of aphid fog.
