When the late sowing fruit vegetables were planted in autumn, they were just before and after the “Evening Autumnâ€. At this time, the solanaceous vegetables that were planted were susceptible to virus diseases, epidemics, stem rot, etc., and the temperature in the greenhouse was reduced. It is very important to reduce the incidence. Its specific temperature reduction measures:
First, increase the amount of air to be blown out, and the arch sheds must be uncovered around them. If the winter shed is to be shed, the top of the shed and the sheds at the front should be opened to increase the amount of bleed air, and an insect-proof net should be installed at the vents.
Second, the use of shading nets or wipes (sprays) mud onto the shed film, reducing light intensity, heavy raining after the rain, more economical but very troublesome.
Third, increase the number of watering, reduce the amount of watering. Under the premise of not affecting the normal growth of crops, under the premise of row or ridge pouring small water, pouring 3 to 5 days, increasing air humidity, reducing the impact of high temperature on the crop. In order to prevent leggy, you can use the “Dwarf Fengling†to irrigate the roots between the plant spacings of the crops, or spray the rejuvenated dew, and spray it once every 6 to 8 days. This also has the effect of inhibiting growth.
