How can cherry tomatoes be grown for high yields? What do you need to pay attention to when growing cherry tomatoes? We also ask experienced netizens to help explain.Cherry tomatoes are a very good health and nutritional food, especially suited to people's pursuit of natural and healthy trends. Moreover, cherry tomatoes look exquisite and cute, have a very high sugar content, about 7-8 degrees, and a sweet, delicious taste with a unique flavor. Another point is that they can be cultivated all year round in our country. Therefore, Zhongdi Wang has compiled the steps for growing cherry tomatoes, listed in detail below for netizens' reference.
Step 1, the growing period for cherry tomatoes:
The cultivation season for cherry tomatoes is similar to that of ordinary tomatoes. For open-field cultivation, spring sowing can be raised as seedlings under protection in February, transplanted after the last frost in late April, and enter the harvest period in mid-to-late June. For autumn sowing, seedlings can be raised in July, transplanted in August, and harvested starting in October. Protected cultivation can appropriately advance or delay cultivation.
Step 2, the seedling-raising method for cherry tomatoes:
1. Preparation of the cherry tomato seedbed:
The seedling bed should be chosen in a plot that has not grown solanaceous vegetables. Choose fertile garden soil and mix in 40%-50% decomposed organic fertilizer. For every cubic meter of nutrient soil, mix in 1 kg of superphosphate and 5-10 kg of plant ash. After mixing, sift and spread it on the seedling bed. For early spring seedling raising, the seedling bed should be set up inside a greenhouse, and if the temperature is too low, electric heating wires should be laid; for summer seedling raising, the seedling bed should be set up in a cool, ventilated place. Summer has a lot of rain, so the seedling bed should have rain-shelter facilities, and there should be drainage ditches at the ends of the bed.
2. Cherry tomato seed treatment method:
Most cherry tomato diseases are spread by bacteria carried on seeds, so seeds should be disinfected before sowing. To prevent viral diseases, trisodium phosphate is mostly used for disinfection in production. The method is: first moisten the seeds with clean water, wrap them well in gauze, place them in a 10% trisodium phosphate solution and soak for 15-20 minutes, take out the seed packet, wrap it well in a warm towel and place it at 28°C for germination. During germination, rinse the seeds once a day. After about 3-4 days, when 1/2 of the seeds have sprouted, they can be sown.
3. Cherry tomato sowing method:
The cherry tomato seedling bed must first be watered. When sowing in early spring, the watering can be appropriately lighter; when sowing in summer, the seedling bed should be fully irrigated. After the water seeps down, sow the seeds evenly, then cover with 1 cm of sifted soil. Use 3-5 grams of seed per square meter of seedling bed. Each mu of planting area requires 6-8 square meters of seedling bed.
4. Management of cherry tomato seedlings:
For early spring seedling raising, attention should be paid to keeping warm. Before emergence, the seedbed soil temperature should be controlled at 25-30°C. For summer seedling raising, rain should be prevented and the temperature lowered. After most seeds have emerged, the temperature should be lowered promptly, controlled at 20°C during the day and 12-15°C at night. When the seedlings grow 2 true leaves, divide the seedlings.
5. Cherry tomato seedling division method:
As early spring temperatures gradually rise, the seedling division bed generally does not need heating wires laid. Early spring seedling division should be carried out on a sunny morning, using the dark-water planting method: first open a furrow, then water, and after the water seeps down, place the seedlings and cover with soil. After covering, no muddy water should be visible on the surface. The plant and row spacing is 10 x 10 cm. Summer seedling division is carried out in the evening or on cloudy days, with the same method as early spring seedling division. The plant and row spacing is 10 x 10 cm. After planting, irrigate, shade the bed, and remove the covering after the seedlings recover. Before the seedlings recover, the seedling division bed temperature should be 25-28°C during the day and 15-18°C at night; after recovery, 20-25°C during the day and 13-15°C at night. Do not water in early spring; water the seedling division bed frequently in summer. Transplant when the seedlings grow to 8 true leaves.
Step 3, the transplanting method for cherry tomatoes:
Before transplanting cherry tomatoes, the soil must first be prepared. In combination with deep plowing, apply 5000 kg of decomposed organic fertilizer per mu, 20 kg of N, P, K compound fertilizer, and 20 kg of superphosphate. After leveling the land, make flat beds 150 cm wide (if mulching film is used in early spring, make small raised beds 10 cm high with a bed surface 50-60 cm wide). For flat beds, transplant 3 rows per bed; for small raised beds, transplant 1 row per bed. The plant spacing is 20-30 cm, and 4500-6000 plants are transplanted per mu. For those using mulching film, first prepare the bed and lay the film, then make transplanting holes according to the plant spacing and transplant, with the transplanting depth such that the cotyledons are 1 cm above the ground.
Step 4, daily management of cherry tomatoes:
1. Watering cherry tomatoes:
After transplanting, water cherry tomatoes thoroughly, and do not water again until the first truss flowers and sets fruit. If little water was used at transplanting, a small amount of water can be poured in a furrow in the bed, carried out on a sunny morning. After the first truss sets fruit, water heavily for the first time. During the fruiting period, the water requirement is high, so water once every 5-6 days, keeping the soil alternately dry and moist. Reduce watering during the harvest period to prevent fruit cracking.
2. Topdressing cherry tomatoes:
After the first truss of cherry tomatoes sets fruit, apply 10 kg of nitrogen-phosphorus-potassium compound fertilizer per mu together with watering. When the first truss fruit changes color, apply 10 kg of compound fertilizer per mu to promote fruit development. After that, apply fertilizer once every time 2 trusses of fruit appear, with 10 kg of compound fertilizer per mu each time.
3. Temperature requirements for cherry tomatoes:
The cultivation temperature for cherry tomatoes is higher than that for ordinary tomatoes. At night, above 10°C is required; during the day, 20-25°C, and the maximum should preferably not be higher than 35°C.
4. Pruning method for cherry tomatoes:
Cherry tomato plants are generally very tall and poor at standing upright. When the plant grows to 50 cm, insert a support to prevent lodging. The side branches have strong growth ability, so double-stem pruning is generally used: first keep 2 strong branches and remove the others. Generally, do not top the plant. When the lower old leaves turn yellow, remove them promptly to reduce nutrient consumption.
5. Flower thinning and fruit retention method for cherry tomatoes:
If pollination is poor in early spring when the temperature is low, flowers are prone to dropping. You can use 2,4-D to smear the newly opened calyx and flower stalk (only smear once). Each truss of cherry tomatoes has many flowers and fruits, so select and keep 20-30 well-set fruits and remove the rest.
Step 5, the harvesting method for cherry tomatoes:
Harvest cherry tomatoes when they are fully ripe, and keep the calyx and a section of fruit stalk when harvesting.
Step 6, pest and disease control for cherry tomatoes:
Common diseases include early blight, late blight, viral diseases, gray mold, and so on. Control method: carry out a 3-4 year rotation with non-solanaceous crops. In the early stage of disease, use 70% mancozeb 500 times solution and 75% chlorothalonil 600 times solution, spraying once every 7-10 days, for 4-5 consecutive sprays. The main pest is aphids, which can be controlled with 20% fenvalerate emulsifiable concentrate 800-1000 times solution and 50% pirimicarb 2000-3000 times solution.
