It rains a lot in summer, how to strengthen protection when planting tomatoes?

4. Topping is done in early to mid-August to control vegetative growth and ensure that the young fruits grow into large fruits before pulling out the seedlings.

Strengthen pest and disease control to ensure healthy growth of plants and fruits. First, insect-proof nets should be installed at the top and bottom air vents to prevent pests from entering the greenhouse through the air vents. If pests such as aphids, whiteflies, cotton bollworms, and tobacco caterpillars have entered the room and harmed the plants, they must be killed in time. Second, attention should be paid to the prevention and control of leaf mold, early blight, gray mold, soft rot, ulcers and other diseases.

Everyone knows that heavy rains have fallen in most areas, and while the harvest of farmers’ fruits has begun, there will be no customer consultation. How do you manage it?

How to cultivate tomatoes, how should you manage them

After the summer solstice and entering the high temperature and rainy season, the temperature is about 35°C or even higher, which is not suitable for the growth and development of tomatoes. Pollination, physiological disorders, difficulty sitting, pests and diseases are also very serious, making summer difficult. Whether protected tomatoes or exposed tomatoes, the vast majority are lost to heat, water and disease. However, tomatoes are in the off-season of 8-7 months, the goods are cheaper, and their economic benefits are very good. Therefore, doing a good job of strict management and extending the life of tomatoes are important measures to improve the economic benefits of tomatoes.

1. Keep the film and dig drainage pipes to prevent rain and water. The top of the top and the bottom of the bottom make the air in the shed smooth and can heat the gas in time to reduce the indoor temperature and air humidity. In addition, the film has caused aging contamination, and the transmittance has dropped to about 50%. It can exert cooling temperature, and the temperature in shedding can be reduced by about 3℃. It is always maintained within the right temperature range for tomato growth and development. Regular pollination and seating of fruits from tomatoes are guaranteed.

2. Detailed budding and strict prevention of vegetative growth, leading to fertility conflicts and fruit drop. Before mid-June, submit a large amount of organic fertilizer in the run, 60-80 kg per trench, to promote soil aeration, strengthen root activity, improve absorption capacity, and maintain strong growth.
