Temperature is the key to the growth of vegetables. High temperature, especially at night, can easily cause vegetables to grow. Therefore, regulating the temperature is one of the technical points of cultivating strong vegetable trees.
For summer vegetables, because their growth is in the high temperature period, the shed often exceeds 40 °C, which affects the normal growth of vegetables, which requires vegetable farmers to regulate in time. In addition to increasing ventilation, we should also pay attention to the application of shading and cooling facilities such as sunshade nets and cooling agents, and try to widen the temperature difference between day and night to prevent vegetables from growing. In general, the temperature of nightshade vegetables should be controlled at 25°C-30°C during the day and 15°C-16°C at night; Melons and vegetables should be controlled at 25°C-32°C, and at night at 15°C-18°C.
Generally speaking, when the temperature in the shed exceeds 35 °C, a shade net should be set on the roof of the shed to cool down, and the shade net covering time should be from 11 am to 2 pm, and avoid covering all day, so as not to affect the normal photosynthesis of vegetables. When the temperature is higher than 18°C at night, the method of strengthening night ventilation (ventilating at the front face + ventilating from the top) should be adopted to reduce the temperature and keep the temperature difference between day and night at about 15°C. After doing enough to work, if the temperature in the shed is still high, you can use water spraying or pouring small water to assist in cooling.
