Polycarbonate Greenhouse for tomato and cucumber

Polycarbonate Greenhouse for tomato and cucumber adopts soilless cultivation technology and drip irrigation fertilization system to realize the integrated operation of water and fertilizer and intelligent management. It can automatically adjust the temperature, humidity, light, carbon dioxide concentration, water and fertilizer, and other parameters in the greenhouse through sensors. The top covering material adopts diffuse reflection float glass covering material, and the ground source heat pump heating system is used for heating in winter, which creates environmental factors that can meet the growth conditions of tomatoes.

It is very important to pay attention to coordinated lighting in protected field cultivation. If artificial lighting is required for continuous cloudy days, special lighting for lighting can be hung indoors, and a reflective curtain on the back wall to increase the light intensity. If there is a strong light in the autumn, you should use shading nets in time to prevent leaf burns due to excessive light, and adjust the plants reasonably to promote the normal development of fruits.

Tomatoes are a kind of temperature-loving fruits and vegetables, which have different requirements for the temperature at different developmental stages. When the temperature is too high, the computer will turn on the fan, sunshade nets, skylights, etc. to reduce the indoor temperature through the set parameters. When the indoor temperature is too low, use the heating system to increase the temperature: generally 13~28℃ It is suitable for the growth of tomato within the temperature range. During the seedling period, the suitable temperature is 20~25℃ during the day and 10~15℃ at night. If the temperature is too high, the seedlings are easy to grow. If the temperature is too low, the flower bud differentiation will be affected. Good effect: 25~28℃ during the flowering and fruiting period and 14-18℃ at night is the normal growth temperature. Too high or too low will affect the normal growth of the plant, higher than 30°C and lower than 12°C will affect the fruit coloring: tomato root growth The suitable ground temperature is 20-22 ℃, lower than 13 ℃, higher than 32 ℃ is not conducive to plant growth and development. The humidity in the greenhouse is required to be 70% to 80%. Excessive humidity can cause fungal diseases.
