How to Increase the Yield of Cherry Tomatoes Grown in Greenhouses
Cherry tomato is commonly known as small tomato, a fruit and vegetable that everyone often eats, and in recent years the cultivation of cherry tomatoes has developed rapidly, with winter planting bringing higher returns. However, winter temperatures are relatively low, and although greenhouse cultivation is used, the yield is still not as good as in other seasons, so how can you increase the yield of cherry tomatoes grown in greenhouses in winter? Let's take a look.
1. Promote seedling recovery
The seedling recovery period of cherry tomatoes after winter planting falls in the cold season, so the greenhouse temperature should be kept suitable, which is good for the growth and development of cherry tomatoes. At the same time, pay attention to adjusting light and humidity inside the greenhouse, and you can spray new high lipid film in time, which can effectively prevent water on the ground from evaporating and water in the seedlings from transpiring, shorten the seedling recovery period, and help the plants adapt to the new environment as quickly as possible so they grow healthily.
2. Fertilizer and water management
During the growing period of cherry tomatoes, water and fertilize reasonably according to the growth needs of the plants, and apply nitrogen, phosphorus and potassium fertilizers in a balanced way to ensure sufficient nutrients for plant growth. Cherry tomatoes grown in greenhouses grow extremely fast, and although the plants are tall, they have poor uprightness, so when the plants grow to 30-40 cm, stakes should be inserted in time to tie the vines or hanging lines should be used for support to prevent lodging. At the same time, spray hormones to force the nutrients at the top of the plant to flow back, directing the nutrients of the main stem to the development of young fruits, thus increasing the speed of fruit enlargement, while also avoiding leaf hypertrophy and excessive growth of branches and leaves, effectively improving field ventilation.
3. Increase the fruit-setting rate
Because the greenhouse environment is closed, with little wind and basically no insect activity, the fruit-setting rate is lower than that of open-field cultivation. To increase the fruit-setting rate of greenhouse cherry tomatoes, generally spray Caiguo Zhuangdiling before flowering, at the young fruit stage and at the fruit enlargement stage, to enhance the quality of pollen fertilization and increase the cyclic fruit-setting rate. It can also promote fruit growth and development, prevent fruit cracking and deformed fruit, further improve fruit quality, and lead to continuous high yields.
4. Prevent and control pests and diseases
Common diseases of cherry tomatoes include bacterial wilt, phytophthora blight and so on. In greenhouse cultivation, ventilation management should be strengthened to reduce humidity inside the greenhouse and reduce the breeding of pathogens. Inspect frequently, and once disease is found, take targeted prevention and control measures, focusing on prevention and protection, while also harvesting at the right time to ensure high yield and good quality.
