How much is a jin of cherry tomatoes in 2020? Key points of cultivation techniques explained
Cherry tomatoes are actually what we call cherry tomatoes, also known as small tomatoes, cherry tomato fruit, cherry tomato, etc. They can be used as both fruit and vegetables, and are deeply loved by everyone. Let's take a look below athow much is a jin of cherry tomatoes in 2020? What are the key points of cultivation techniques?
I. How much is a jin of cherry tomatoes in 2020?
According to relevant websites, the recent price of cherry tomatoes is roughly 1.2-4 yuan per jin, and the price will be affected by factors such as place of origin, variety, market conditions, purchasing channel, and product quality.
II. What are the key points of cherry tomato cultivation techniques?
1. Cultivation season: The cultivation season of cherry tomatoes is similar to that of ordinary tomatoes. For open-field cultivation, spring sowing can be raised as seedlings in protected areas in February, transplanted after the last frost in late April, and enters the harvest period in mid-to-late June. Autumn sowing can be raised as seedlings in July, transplanted in August, and begin harvesting in October. Protected cultivation can appropriately advance or delay cultivation.
2. Seedbed preparation: The seedling bed should be selected in a plot that has not grown solanaceous vegetables, choose fertile garden soil and mix in 40-50% decomposed organic fertilizer. For each cubic meter of nutrient soil, mix in 1 kg of superphosphate and 5-10 kg of plant ash, sieve after mixing, and spread it on the seedling bed. For early spring seedling raising, the seedbed should be set up in a greenhouse, and if the temperature is too low, electric heating wires should be laid; for summer seedling raising, the seedbed should be set up in a cool, ventilated place. There is a lot of rain in summer, so the seedling bed should have rain-shelter facilities, and there should be drainage ditches at the ends of the bed.
3. Seed treatment before sowing tomatoes: To achieve high yield and increased income when growing tomatoes, the seeds must be treated before sowing. Diseases of cherry tomatoes are mostly spread by bacteria carried on seeds, so seed disinfection should be carried out before sowing. To prevent the occurrence of viral disease, trisodium phosphate is often used for disinfection in production. The method is: first moisten the seeds with clean water, wrap them well with gauze, place them in a 10% trisodium phosphate solution and soak for 15-20 minutes, take out the seed packet, wrap it well with a warm towel and place it at 28°C for germination. During germination, rinse the seeds once a day, and after about 3-4 days, when 1/2 of the seeds have sprouted, they can be sown.
4. Seedling management: For early spring seedling raising, attention should be paid to keeping warm, and before emergence the seedbed soil temperature should be controlled at 25-30°C. For summer seedling raising, rain should be prevented and temperature reduced. When most seeds have emerged, the temperature should be lowered in time, controlled at 20°C during the day and 12-15°C at night. When the seedlings grow two true leaves, divide the seedlings.
5. Seedling division: As the temperature gradually rises in early spring, the seedling division bed generally does not need electric heating wires. 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. Plant spacing and row spacing are 10×10 cm. Summer seedling division is carried out in the evening or on cloudy days, with the same method as early spring seedling division. Plant spacing and row spacing are 10×10 cm. After planting, irrigate, shade the ridge, and remove the covering after the seedlings recover. The temperature of the seedling division bed before recovery is 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.
6. Field planting: First prepare the land, and in combination with deep plowing, apply 5000 kg of decomposed organic fertilizer, 20 kg of N, P, K ternary compound fertilizer, and 20 kg of superphosphate per mu. 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 and 50-60 cm wide at the bed surface). For flat beds, plant 3 rows per bed; for small raised beds, plant 1 row per bed. Plant spacing is 20-30 cm, and 4500-6000 plants per mu. For those using mulching film, first prepare the bed and lay the film, then punch planting holes according to the plant spacing and plant, with the planting depth such that the cotyledons are 1 cm above the ground.
7.Watering: If enough water is applied at planting, there is no need to water again until the first truss blooms and sets fruit. If less water is applied at planting, a small amount of water can be poured into 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 demand is high, so water once every 5-6 days, requiring alternating dry and wet conditions. Reduce watering during the harvest period to prevent fruit cracking.
