In the spring season, air drying and large changes in temperature and humidity have become the key factors affecting greenhouse vegetables. Dry air is prone to fire, machinery and equipment wear will cause collapse of the shed body, changes in temperature and humidity affect the normal growth of vegetables, so it is necessary to grasp the current management of greenhouses is very necessary, only the shed itself is safe, there will be a vegetable growth Safe space.
Do a good job of fire prevention to ensure the safety of the property in the shed
First, the weeds around the greenhouses and the waste that has been stored outside the shed should be disposed of. In general, air drying in early spring is particularly prone to cause large-scale fires. Weeds and weeds on piles of vegetables around the greenhouse must be treated in a timely manner. Eradicate the weeds or cover them with soil and dispose of the deposits in a timely manner to reduce the risk of fire.
Second, check the electricity in the booth. Part of the fire in the shed was caused by combustibles, and the other part was caused by a short circuit in the live line in the shed. It is necessary to regularize and inspect the wires in a timely manner so as to avoid a fire accident in the greenhouse caused by a short circuit of the wires.
Once again, pre-placed soil bags around the sheds will temporarily store some of the water in the pools and buckets inside the sheds and be treated in time if a fire occurs.
At the same time, it is suggested that vegetable growers who are far from the village in the sheds can install equipment with fire alarm functions in the sheds to strengthen supervision of the safety of sheds.
Check early to ensure the safety of machinery facilities
For the sheds, the most frequent accidents are caused by the failure of the shutters, so it is necessary to check the operation of the shutters in time.
First, it is necessary to promptly check the corrosion and bolting of the connection between the support arm and the machine head. This is the maximum stress point. If serious corrosion and bolt looseness occur, accidents can easily occur.
Second, check the link to the roll bar. For longer booths where only one roller shutter is installed, if the connection between the roll bars is loose, the grass curtain may be bent. If the force is greater, it is likely to cause breakage and cause accidents.
Third, the brake inspection of the shutter head is also necessary. The brake pads, pawl ratchets and related springs for the nose should be inspected. If they are damaged or worn, replace them promptly.
When the shutter is at a standstill, all the switches should be completely cut off to avoid short circuits causing the shutter to run excessively and cause accidents.
Control the temperature and humidity environment to ensure the safety of vegetable growth
For temperature regulation, it is mainly the nighttime insulation and the closing of the daytime tuyere. If you plan to put your sheds early in the evening, you can extend the air release time in the afternoon and reduce the temperature in the shed by 2°C~3°C than usual, so that if you put the shed early, there will be no higher nighttime temperatures in the first half of the night. In the daytime, the opening and closing of the air outlet is still small and large, step by step, especially for vegetables, such as tomatoes, cucumbers, etc., it is necessary to pay attention to the temperature stability.
For the regulation of humidity, in the case of good lighting conditions and high temperature in the greenhouse, vegetables may be more prone to bacterial diseases if there is high humidity. Therefore, there is an early improvement in the situation where dripping or standing water occurs in the shed. Some sheds are dripping due to flat surfaces, while others are skeletons or wires that prevent them from dripping and dripping. Especially when the film rope is too tight, dripping between lines is particularly serious. Therefore, it is necessary to relax the film rope in time to reduce the occurrence of drip. At the same time, rice husks, straws, etc., can be spread between the original rows of dripping water to absorb moisture and reduce the air humidity in the shed. In addition, qualified vegetable farmers can adopt reasonable application of fumigant or mist sprayer when controlling disease.
