When will cherry tomatoes be planted? With planting technology!

Cherry tomatoes, also known as virgin fruit, taste delicious, the market demand is large, the planting area is also relatively wide. So, when will the cherry tomatoes be planted? What are the planting techniques of cherry tomatoes? Let's have a look!

Planting time of cherry tomatoes

1. Planting time of spring tomatoes

The suitable seedling age for spring tomato cultivation in open field is 50 meters for 70 days, that is, the seedlings should be sowed for 50 tons of 70 days before planting. For example, in Shenyang, which is located at latitude 41 north, spring tomatoes are planted in protected areas in February and planted in the open field after the late frost in early May.

Spring tomatoes are generally planted immediately after the local late frost period, when the soil temperature of the ploughed layer of 5m / 10cm stably passes through 12 ℃. For example, the average late frost period in Shenyang is May 2, and the suitable planting period is generally May 6-10. The Yangtze River basin is generally around the Qingming Festival, North China before and after Grain Rain, and the northeast region before and after the Beginning of Summer. The sandy land with Phoenix barrier, plastic film cover, and leeward and sunny terrain can be planted early. Planting should also be determined according to the weather conditions. In case of cloudy, rainy and Phoenix weather, planting should be postponed appropriately. In the suitable planting period, Shaanxi tomatoes should be planted early, mainly according to the time on the market, there are mainly two seasons a year, one is delayed cultivation after autumn, the seedlings start after July and August, and can be put on the market one after another in November. One is cultivated in early spring, raising seedlings in November and February and listing in May and June.

2. Planting time in autumn and winter.

The autumn and winter stubble is generally sown and raised seedlings from mid-July to early-middle August, and planted from mid-late August to early September. The plastic film was buckled from mid-late September to early October and harvested from late November to early February of the following year.

3. Planting time in winter and spring.

The winter and spring stubble was sown from early November to early December, planted from mid-late January to early February, and harvested from early-mid-March to June the following year.

4. Planting time of overwintering stubble

Overwintering stubble belongs to a large stubble cultivation. Generally, seedlings are raised from mid-late September to early October, planted in November, and harvested in January of the following year.

2. Planting techniques of cherry tomatoes

1. Seedbed preparation

The seedling bed should be selected in the plot that has not planted eggplant vegetables, select fertile pastoral soil mixed with 40% Mel 50% mature organic fertilizer, every 3 meters of nutrient soil mixed with calcium superphosphate 1kg, plant ash 5-10kg, mixed and sifted, laid on the seedling 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.

2. Seed treatment

The diseases of cherry tomato are mostly transmitted by seeds, so seeds should be sterilized before sowing. In order to prevent the occurrence of virus disease, trisodium phosphate is used to disinfect it in production. The method is as follows: first, wet the seed with clean water, wrap it with gauze, soak it in 10% trisodium phosphate solution for 15 minutes for 20 minutes, and take out the seed bag. Wrap it in a wet towel and place it at 28 ℃ for budding. During the period of germination, the seeds were washed once a day, and the seeds could be sown when the seeds were exposed to white in about 4 days.

Cultivate strong seedlings: the nursery bed must choose the land with high dryness and good drainage, and add rain protection and sunshade equipment. Three to four days before sowing, the seeds were soaked with 10% trisodium phosphate for 20 minutes, washed and germinated at room temperature. After germination, the seeds were sown at 4: 00-5: 00 p.m.

3. Sowing and post-sowing management

The seedling bed is watered first, and the watering can be smaller when sowing in early spring. In summer, the seeding bed should be fully watered, and after the water seeps down, the seeds should be evenly sown, and then covered with 1cm to sift the soil. Every square meter nursery bed needs 5g seed, and each mu planting area needs 6Mel 8.2 nursery bed.

Seeds are generally sown in North China from mid-late July to early August. Before sowing, the seedling border is watered with bottom water, and after the water seeps down, it is sown in holes, sowing 3 seeds in each hole and covering the soil 1 cm thick to keep the soil moist. After emergence, only one seedling is left in each hole, and the rest are pulled out. After about 20 days, the seedling is 15 cm-20 cm high and can be planted with 3-4 true leaves.

4. Seedling management

Heat preservation should be paid attention to in early spring, the ground temperature of seedling bed should be controlled at 25 ℃ 30 min before emergence, and rain and temperature should be protected in summer. When most of the seeds emerge, the temperature should be controlled at 20 ℃ during the day and 15 ℃ at night. When the seedlings grow 2 true leaves, the seedlings are divided.

5. Divide the seedlings

The temperature is getting higher and higher in early spring, 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 × 10cm. 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 × 10cm. 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 ℃ at night before seedling retardation, and 20 ℃ in daytime and 13-l5 ℃ at 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.
