How to increase the yield of cherry tomatoes in greenhouses? The latest cultivation techniques
Cherry tomato, commonly known as small tomato, is a fruit and vegetable that people often eat, and in recent years the cultivation of cherry tomatoes has developed rapidly, and the benefits of winter planting are higher. 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 should cherry tomatoes be grown in winter greenhouses to increase yield? Let's take a look together.
1. Promote seedling recovery
The seedling recovery period of cherry tomatoes after winter planting coincides with the cold season. The greenhouse temperature should be kept suitable, which is beneficial to the growth and development of cherry tomatoes. At the same time, attention should be paid to adjusting light and humidity in the greenhouse, and new high-lipid film can be sprayed in time. This can effectively prevent water on the ground from evaporating and water in the seedlings from transpiring, shorten the seedling recovery period, and promote the plants to adapt to the new environment as soon as possible so that they grow healthily.
2. Fertilizer and water management
During the growth period of cherry tomatoes, watering and fertilization should be carried out reasonably according to the growth needs of the plants, and nitrogen, phosphorus, and potassium fertilizers should be applied in a balanced way to ensure sufficient nutrients for plant growth. Cherry tomatoes grown in greenhouses grow extremely quickly. Although the plants are tall, their uprightness is poor, 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, hormones should be sprayed to force the nutrients at the top of the plant to flow back, shifting the nutrients in the main stem to young fruit development. This increases the speed of fruit expansion, and can also avoid leaf hypertrophy and excessive growth of branches and leaves, effectively improving field ventilation.
3. Increase 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. In order to increase the fruit-setting rate of greenhouse cherry tomatoes, generally before flowering, at the young fruit stage, and at the fruit expansion stage, spray Caiguo Zhuangdiling 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 achieve 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. Frequent inspections should be carried out. Once diseases are found, targeted prevention and control measures should be taken to prevent and protect, and timely harvesting should also be done to ensure high yield and good quality.
