High quality and efficient cultivation techniques of Cherry Tomato

Cherry tomato, also known as mini tomato, mainly eats its fresh fruit, the fruit is small, the single fruit weight is 10 ~ 20 g, the plant growth potential is strong, the fruit is more, each plant has 400 ~ 500 fruits. The shape of the fruit is spherical, jujube-shaped, pear-shaped, etc., which has high ornamental value and rich nutritional value, and is rich in soluble sugar, organic acid, protein, carotene, vitamins, minerals and other nutrients. The sugar content of mature fruit is as high as 8% to 10%, suitable for sour and sweet, unique flavor, and is deeply loved by people. Cherry tomato is a temperature-loving fruit vegetable, 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 ℃. Cherry tomato is easy to drop flowers and fruits, requires less water in the early stage and more in the later stage, and has strong adaptability to soil, which is the best in sandy soil and likes potash fertilizer. The yield of cherry tomato is relatively low, with 2000~2500kg per mu, and the sales price is higher in spring, summer and autumn, especially in spring and summer, the main varieties are holy girl, dragon girl and so on. The main cultivation techniques are as follows: 1. The cultivation season of cherry tomato is similar to that of common tomato. In open field cultivation, spring sowing can raise seedlings in the protected field at the beginning of February, plant in 5 to 6 true leaves, and enter the harvest period in early May. Autumn sowing can be raised in June, planted in July and harvested in September. Protected cultivation can be cultivated in advance. 2. Sowing and raising seedlings 2.1, seed treatment is to prevent the spread of seeds with bacteria, so seeds should be disinfected before sowing. Seed disinfection can be soaked in warm soup or medicament. Soak tomato seeds in warm soup: soak tomato seeds in cold water for 10 minutes, then put tomato seeds in hot water of 50: 55 ℃, stir constantly and quickly, make the seeds heated evenly, and replenish hot water at any time, keep the water temperature stable at 50: 55 ℃, 15: 20 minutes later, remove the residual heat in cold water, and then soak in warm water of 25: 30 ℃ for 4 hours. Soak the seeds with agents: wrap the seeds in gauze and soak them in 10% trisodium phosphate aqueous solution for 20 minutes for 30 minutes, then take out the seeds. Wrap it with a wet towel and put it at 25: 28 ℃ to accelerate germination. During the period of germination, rinse the seeds with about 25 ℃ of warm water once or twice a day. After 2 to 3 days, the seeds can be sown when the seeds are white. 2.2.2.After sowing, water the prepared seedbed, wait for the water to seep, sow seeds evenly after 3 hours, and then cover with 0.5-1 cm to sift the soil. The amount of seed used per square meter of seedling bed is 3: 5 g, and the planting area per mu needs 8~10m2 seedling bed. 3. Planting when the seedlings grow 5-6 true leaves, double-row planting is carried out in each row, small row 60cm, plant spacing 35~40cm, 2500 ~ 3000 plants per mu. The plastic film should be covered first, and then the planting holes should be fixed according to the distance between the plants. the suitable planting depth should be 1 cm from the cotyledon to the ground, and the planting water should be poured thoroughly when planting. Field management, such as watering, topdressing, temperature management, pest control and so on, is the same as conventional seed retention. 4. The pruned cherry tomato grows rapidly in the greenhouse, and the plant is tall and erect. When the plant grows to 30~40cm, it should be pulled by a pole or cable to prevent lodging. The lateral branches have strong growth power, and generally carry out multi-layer + continuous 2-layer coring pruning, that is, retaining the inflorescences on the trunk, leaving the lateral branches on the trunk, leaving 2 inflorescences on each side branch, and then leaving 2 leaves on the inflorescence. It is necessary to strike the branches (excess axillary buds) and twist the side branches in time, so that the side branches do not block each other, twist branches generally in the afternoon, and remove the lower yellowing old leaves and diseased leaves in time, so as to reduce nutrient consumption and enhance light transmittance. 5. Sparse flowers and protect fruit when the temperature is low in early spring, poor pollination is easy to fall flowers. 24 drops can be used to smear the newly opened calyx and flower stalk (only once). Cherry tomatoes blossom and bear more fruits per panicle. 20-30 fruits with good fruit setting can be selected, and the rest can be removed. 6. The harvest period is determined according to the transportation situation. The fruit can be harvested when the fruit is discolored during long-distance transportation, when the local sales are fully mature, and the sepals and a section of fruit stalk should be retained when harvesting.
