Some items in the greenhouse inspection

For the shed pipe, most of the safety accidents are caused by the failure of the roller blind machine. Therefore, it is necessary to check the operation of the roller blind machine in time.
First, it is necessary to check the support arm and the corrosion and bolt fixing at the joint of the machine head in time. Here, the force point is large. If there is serious corrosion and loose bolts, it is easy to accident.
Second, check the link of the roll bar. For a long shed with only one roller blind, if the connection between the rollers is loose, the curtain may bend. If the force is large, it may break and cause an accident.
Third, the brake inspection of the roller head is also very necessary. Check the brake pads, ratchet ratchets and related springs of the machine head. If there is damage or serious wear, replace it in time.
When the roller blind machine is at rest, all the switches should be cut off to avoid a short circuit and cause the roller blind machine to run too much.
Regulate the temperature and humidity environment to ensure the safety of vegetable growth.
For the temperature adjustment, the main reason is the insulation at night and the closing of the daytime tuyere. If you plan to put the shed early in the evening, you can extend the air release time in the afternoon and lower the temperature in the shed by 2 °C ~ 3 °C, so that in the case of early shed, there will be no higher temperature in the middle of the night. In the daytime, the opening and closing of the air outlet is still small and large, step by step, especially for tomatoes, cucumbers and other fragile vegetables, the wind needs to pay attention to the stability of temperature.
