How to plant cherry tomatoes out of season? What techniques are there in the cultivation process?

Cherry tomato is also our common cherry tomato, also called pocket tomato, which is an improved variety of tomato. At present, the area planted with cherry tomatoes in China is also relatively large. After all, the value of cherry tomatoes is higher than that of ordinary tomatoes, especially the mode of anti-season planting. The value of cherry tomato is reflected in its high price, and its sugar content is also very high, which is dozens of times higher than that of ordinary tomato. At present, picking gardens in many areas are also planted out of season, especially in winter. Today, I will talk about the planting techniques of cherry tomatoes and how to plant them out of season. I hope this article can help the farmers.

First of all, we must determine the anti-season planting time of cherry tomatoes.

For ordinary cherry tomatoes, you can plant them twice a year, and you can plant them in other seasons. After all, the planting mode of cherry tomatoes is similar to that of ordinary tomatoes, but for the cultivation of cherry tomatoes in greenhouses that are out of season, the planting time must be determined. For example, the wintering planting mode belongs to anti-season planting, and wintering cherry tomatoes are generally planted in July every year. Transplanting at the end of July or the beginning of August can be picked in the current year109-June, and the picking time is usually in June 1- February of the following year, which is also the best income-generating and income-increasing mode of the current winter planting mode. After choosing the planting time, we should deal with the greenhouse in advance. If we use the old greenhouse, we should disinfect it to prevent the emergence of bacteria.

Choose suitable varieties before planting and make preparations before seedling raising.

Planting cherry tomatoes should also choose varieties with high yield, strong cold tolerance and early maturity, such as Saint 1 and Saint 2, Sweet 20, Emerald, Red Diamond and Yellow Diamond. , are now better varieties. After selecting the varieties, the seeds should be treated. In the early stage, it should be dried in the sun, usually for more than 2-3 hours. Soak the seeds in clear water for more than 4-5 hours, then take them out to dry, and soak them in chlorothalonil and agricultural streptomycin for more than 30 minutes. After taking it out, it is ready to put it into an incubator at about 28 degrees to accelerate germination, and sow it in time after accelerating germination.

Scientific seedling raising and seedbed treatment

When cherry tomatoes are sown, sterile seedbeds should be used for sowing. Before planting, the soil of seedlings should be disinfected. Disinfectants and pesticides should be used to disinfect soil and kill eggs. At the same time, fully decomposed farmyard manure was applied to the seedling soil, and then 1 kg calcium superphosphate and 10 kg plant ash were added to the nutrient soil. For cold weather in winter, electric heating auxiliary equipment should be used for seedbed. If you use plug to raise seedlings, you need to disinfect the plug in advance before raising seedlings. The seedling temperature must be controlled well, and the seedling temperature should be controlled between 20 and 25 degrees. When seeds emerge, the daytime temperature is controlled at about 18-20 degrees, and the nighttime temperature is about 12- 15 degrees. When two real leaves appear, they can be transplanted separately.

Preparation before planting

Before planting cherry tomatoes, soil preparation should be carried out first, and continuous cropping should be avoided in the planting area. The rotation field should be kept for more than 2-3 years, and the soil should be deeply cultivated to remove impurities in the field. Then, 5000-6000 kg of decomposed farmyard manure, 20 kg of compound fertilizer and 0/5 kg of calcium superphosphate/kloc should be applied per mu. Conditional can use high-quality cake fertilizer, increase production, soil preparation and fertilization.

Field management of field planting

When planting, we must pay attention to the fact that the planting density should not be too large, and the spacing between plants should be about 20-30 cm. Generally, it is advisable to plant 4500-5000 plants per mu. Be sure to pour enough planting water after planting. Planting water must be watered in sunny mornings to keep the soil moist at ordinary times. Plants should be watered and fertilized after they grow the first ear and bear fruit. After watering, compound fertilizer should be applied to each mu. Then, when the fruit turns color, topdressing should be done once per mu, mainly with compound fertilizer, about 10 kg per mu, and topdressing 10 kg when the second ear fruit appears. The temperature in the field should be controlled well. The temperature should be kept between 20-25 degrees during the day, above 12 degrees at night, and the temperature should be reduced when it is higher than 30 degrees.

During the growth period of cherry tomato, when the plant grows to 25 cm, it should be fixed by hanging vines, and when it grows to 50 cm in the later period, it should be trimmed. Generally, only two main branches can be left in the plant, and other side branches should be cut off in time, and the old leaves and yellow leaves at the lower part of the plant should be cleaned up in time. In order to reduce the flower drop caused by poor pollination, we applied 2.4 drops of calyx and pedicel when leaving fruit. It is advisable to choose 20-30 fruits per branch, and it is not advisable to leave too many fruits. Diseases and insect pests in the field should be prevented in time. The common diseases and pests of cherry tomatoes are Fusarium wilt, gray mold, virus disease, aphid, whitefly and so on. Drugs such as chlorothalonil, mancozeb, pesticide polyester, deltamethrin and acaricide can effectively inhibit the occurrence of diseases.
