The summer and autumn seasons are the main flood seasons in northern China, and the rainfall has increased significantly. The safety management of sheds should pay attention to rain protection. Prevent rainwater from entering the shed Clearing the drainage ditch in advance and preventing rainwater from pouring into the shed found that many drainage ditches near the sheds are full of garbage, so that when heavy rain comes, it is very easy to cause rainwater to drain away and pour into the shed. Therefore, it is recommended that vegetable farmers must pay attention to checking whether the drainage ditch around the greenhouse is unobstructed during rainy weather and clear the drainage ditch in time to prevent rainwater from pouring into the shed. If there is no drainage ditch, you must seize the time and dig the ditch at the front of the shed. The ditch width is 30 cm and the depth is 40 cm. Pay attention to watching the weather forecast and close the vents in time before the rain. The temperature in the summer shed is very high. In order to reduce the temperature in the shed, the farmers generally increase the ventilation, but before the rain, close the vents in time to prevent the rain from entering the shed. And the bacteria carried by the raindrop splashed mud spot soaked vegetables. In continuous rainy weather, it is best to install a rain film at the air outlet of the greenhouse to prevent the raindrops from falling onto the leaves of the vegetables, and not to interfere with the ventilation and cooling of the greenhouse during the rain. Doing some repair work on the shed film Some vegetable farmers believe that the increase in outside temperature and the damage to the vegetables caused by the damage to the shed film have reduced the impact on the vegetables. As a result, the damaged shed film has not been repaired in time. As a result, rain has entered the shed and the growth of vegetables has been affected. serious. Therefore, the repair of the shed film must also be done well. Timely remediation after the shed After rainwater irrigation, if the rescue measures are not in place, it will affect the normal growth of vegetables, yellow leaves, wilting, and even dead trees. In view of this, it is necessary to remind the vegetable farmers to remediate in time after rainwater irrigation. Excluding stagnant water in the shed for a long period of time can easily cause the roots of the crops. After the roots are damaged, it provides an opportunity to spread the germs. Therefore, once the rainwater is shed, it is necessary to drain water in time to shorten the soaking time of vegetables in rainwater. In the process of removing accumulated water, it is best to clean the leaves of the crop while draining, so as not to accumulate silt on the leaves of the crop, affecting photosynthesis, and resulting in slow crop growth. After timely cultivating rainwater irrigation, the soil in the shed will be filled with rainwater and the soil permeability will be deteriorated. If measures are not taken in time, it will easily affect the growth of vegetables. Therefore, the cultivator must be cultivated in time after drainage in order to increase the permeability of the soil and promote the root system of vegetables to resume growth as soon as possible. Timely watering, combined with timely application of water after spraying biological bacteria fertilizer, diluting the rainwater of the breeding bacteria, can reduce the probability of bacterial infection, combined with the application of microbial fertilizer, such as bacteriostatic 968, 50 kg per acre , Can effectively solve the problems such as shed floor knots, poor ventilation, and promote the recovery of vegetables. Irrigate vegetables in greenhouses that have been soaked in rainwater in a timely manner. It is prone to bacterial diseases and root rot. After the drainage, timely medication prevention can prevent the occurrence of the above-mentioned diseases. Such as the prevention of bacterial diseases can be sprayed with agricultural streptomycin or copper preparations; prevention of root rot can be used 72.2% Prec 600 times liquid plus 1000 times potassium subsidence root irrigation. Pay attention to protect the shelter When there is a lot of rain in the summer and autumn seasons each year, there are cases where a large shed or arch shed collapses and it takes time and effort to build. Therefore, it is recommended that farmers always pay attention to protecting the shed.
