How to grow cherry tomatoes? How to grow cherry tomatoes

How to better cultivate cherry tomatoes is also a question that many people are concerned about. Let me tell you about it below:

(1) Seedbed preparation.

The seedbed should be sheltered from the wind and facing the sun, with good drainage. A 667 square meter field requires a 6-7 square meter nursery bed and a 35-40 square meter transplanting bed. Apply 1,500 kg of decomposed human feces and urine per 667 square meters of the seedbed soil, and cover it with 8 cm thick nutrient soil. The nutrient soil is half fully decomposed organic fertilizer and half fertile soil that has not been planted with Solanaceae crops. Mix and sieve 7-10 days before sowing, and mix with 5 kg of superphosphate, spray carbendazim to disinfect the soil, and pile it up for use.

(2) Sowing period.

Sow seeds in advance to extend the harvest period as much as possible. Using small arch sheds to raise seedlings can both sow seeds earlier and reduce the occurrence of seedling diseases. Generally, sowing is done in late April.

(3) Soaking seeds to accelerate germination.

Use 20 grams of seeds for 667 square meters. Soak them in 1000 times potassium permanganate solution for 10 minutes, then rinse with clean water and soak them in warm water for 6 hours. Wash the seeds, dry them, keep them moist with wet gauze, germinate at about 25℃, and sow them after they turn white.

(4) Sowing and post-sowing management.

Cherry tomato seeds are expensive. To ensure a high success rate, the seeds are required to be sown in separate pieces and covered with 0.5 cm of nutrient soil. Keep a high temperature before germination, and pay attention to ventilation to prevent leggy growth after germination. When the seedlings have two leaves and one heart, choose healthy and disease-free seedlings and transplant them with fertilizer, medicine and soil in the evening on a sunny day. The transplanting seedling bed is the same as the nursery bed, and water is poured after transplanting to establish roots.

(5) Prevent diseases at the seedling stage and control excessive growth.

There are many diseases in tomato cultivation areas. Copper ammonium chloride or Green Heng No. 2 can be used to prevent and treat damping-off and early blight. Spray once every 7 to 10 days, and use it 2 to 3 times in a row. After the seedlings are transplanted and survive, before transplanting, spray 1500x10-6 Biju or sprinkle 300x10-6 dwarfing agent according to the growth of the seedlings, which can increase leaf color and inhibit excessive growth. If the growth is too vigorous, spray again after three weeks.

Planting method of cherry tomatoes: 1. Open field cultivation: 1. Spring tomatoes: In December, hot wires and small sheds are used to raise seedlings in the greenhouse. After covering with plastic film in late March, they are transplanted into the field and harvested from late May to late July. Select early-maturing and high-yielding varieties such as Sijihong and Shengnu. 2. Autumn tomatoes: Sowing and raising seedlings in late June, nutrient pots can be used for seedling raising, transplanting in late July, and harvesting from late September to before frost. Sijihong varieties can be selected. 2. Protected cultivation: 1. Small shed covering cultivation: In January, hot wires and small sheds are used to cover seedlings in the sunbed or greenhouse, and transplanting is carried out in early to mid-March. It is best to cover with plastic film before transplanting. After transplanting, the small shed is closed. It is supplied to the market from May to July, which can be put on the market about one month earlier than the open field. 2. Greenhouse cultivation: In early December, seedlings are raised on cold beds or electric heating wires in the greenhouse, and transplanted in late February. The greenhouse is covered with a small greenhouse, and harvested from April to early August. Select early-maturing, high-yield, and high-quality varieties. 3. Rainproof shed cultivation: Similar to greenhouse cultivation, except that the greenhouse canopy is not opened during the entire period, and only the apron curtain is removed, so that the canopy can play a role in rain protection during the rainy season and summer. The canopy is covered with a sunshade net, which has a cooling effect and can extend the supply period of tomatoes to August or even September. Varieties resistant to bacterial wilt can be selected. 4. Greenhouse autumn delayed cultivation: Sowing in late June to early July, transplanting at the end of August, and listing from September to December. Cover the greenhouse film in October for heat preservation, and multiple covers are feasible to extend the supply of fresh tomatoes until New Year's Day. 5. Solar greenhouse cultivation: In areas with sufficient sunlight in winter, spring tomatoes can be grown in solar greenhouses and put on the market earlier. Generally, seedlings are raised in October, planted in November, and the tomatoes are available on the market from February to late June.

The optimum temperature for cherry tomatoes is 24-31℃. They prefer to be planted in soil with strong light and deep soil. The cultivation of cherry tomatoes should be based on loam with rich organic matter, deep tillage layer, good structure, loose and breathable soil. When preparing the land, the width of the ridge is 1.5 meters, the height of the ridge is 25 cm, and the width of the ridge furrow is 40 cm. A 1.5-meter-wide ridge field can be planted with 4 rows, with a spacing of 25-30 cm, and 6,000-8,000 plants can be planted per mu. When planting, first dig a furrow in the ridge or on a half-high ridge with a depth of 15 cm. After digging the furrow, spread 250 kg of decomposed dry manure per mu, increase the application of phosphorus fertilizer, and spread 30 kg of superphosphate per mu at the same time. Cherry tomatoes are small in size, large in number, and grow vigorously. When cultivating, pay attention to increasing the number of fruits, making the fruit small and uniform, using double-stem pruning, and cutting off the remaining side branches. In order to make the fruit have good color and high sugar content, more phosphorus fertilizer should be applied.
