-_ Requirements for environmental conditions
1, temperature.
The optimum temperature for tomato growth and development is 24 ~ 26 degrees Celsius. When the temperature is lower than 5 degrees Celsius or higher than 40 degrees Celsius, tomatoes will stop growing.
2. Lighting.
Tomato is a photophobic crop and sensitive to light.
Sufficient sunlight, vigorous plant growth, thick stems and strong resistance.
Insufficient light will lead to excessive growth, less flowering, falling flowers and fruits, etc.
3. Moisture.
Tomato is a deep-rooted crop, which is not only not afraid of drought and flood, but also has good soil drainage, low groundwater level and uniform water supply.
Tomato planting techniques
ニ _ Tomato Cultivation Techniques
1_ sowing date.
-Spring sowing 65438+1late October to February, autumn sowing July to August.
In summer sowing, the temperature is high, the plants grow weakly, there are many fallen flowers, it is difficult to set fruit, the diseases are serious and it is easy to fail.
Winter planting is only suitable for southern plains or low-altitude hilly areas, and the sowing time is from June 65438+1October to1early October165438+1October.
2_ Seed disinfection.
Seed disinfection is an effective measure to reduce the spread of diseases.
During disinfection, the seeds can be wrapped in gauze, soaked in warm water of 50℃ (constant temperature) for 10 minutes or soaked in sodium phosphate solution of 10% for 20 minutes, then taken out, rinsed with clean water, soaked in warm water of 30℃ for 2-3 hours, and then taken out and dried in the shade.
3_ Seedling management.
It should be determined according to different climatic conditions, such as planting in winter or raising seedlings in early spring, and plastic film should be covered in the small arch shed.
In summer and autumn, we should focus on preventing high temperature and heavy rain, and build sheds with sunshade nets to cover them.
In the process of seedling raising, appropriate topdressing, combined with general watering, and irrigation with decomposed urine water or 0 _ 1 _ 2 _ urea water.
At the same time, 600 times of chlorothalonil and 1000 times of dimethoate were sprayed 2 ~ 3 times at seedling stage.
