Recently, due to frequent rainfall, a large amount of rainwater has entered the vegetable shed, causing some vegetables to have a more serious dead tree phenomenon. The occurrence is characterized by the death of many sides of the shed, the air outlet and the shed surface. After the rain enters the shed, how can I prevent the dead vegetables? The vegetable farmers can take the following measures.
First, the rain should be eliminated as soon as possible. After the shed is filled with rainwater, the water should be managed in the shortest time to avoid the accumulation of water and avoid the infiltration of the rainwater in the planting line. The shed with drainage conditions can lead the water to the ditch, and the shed with no ditch around the shed should use the pump, water belt, etc. to drain the cistern into the ditch at the first time. The root resistance of vegetables after roots is poor, and it is very easy to be infested by rainwater and harmful bacteria in the soil.
The second is to make timely arrangements. After draining the accumulated water, the soil in the shed will be drained in time to see the wetness, so as to increase the permeability of the soil and promote the normal growth of the vegetable roots as soon as possible. The depth of the stroke varies according to the growth of the roots of the vegetables. For example, the newly planted vegetables are flooded with rain. Because the root system does not expand in a large area, the depth of the stroke can be deeper; if the roots of the seedling stage have been expanded, the roots can be drawn. The depth is controlled at about 3 cm, and not too close to the plant. If you have a good grasp of the depth of the stroke, it is recommended to stay away from the roots of the plant.
The third is to use the medicine to fill the roots in time. In order to avoid dead trees, the vegetables that are flooded should be rooted once in time when the soil is suitable. The root can be filled with 30% of the carbendazim 1000 times solution or 50% of the chlorobromoisocyanuric acid 1000 times solution. When rooting, it can be mixed with appropriate amount of rooting agent or chitin, such as Apollo 963 nutrient, to promote wound healing and regeneration. Do not use too high a concentration of the medicine, otherwise it will easily damage the root system.
The fourth is to increase the application of biological fertilizer. The use of biological bacteria to inhibit the bacteria, after the rooting with the agent for 7 days, can be followed by watering. It should be noted that the fungus fertilizer should not be used at the same time as the fungicide. It should not be used during the peak period of the efficacy of the fungicide. Be sure to pay attention to the safety interval between the two. Applicable bacterial fertilizer products include bacteria, antibacterial 968 seedling period fertilization, ETS microbial agents.
In addition, the vegetable farmers must repair the damaged shed film in time, and install rain-proof walls and rain-proof membranes on both sides of the shed to prevent rain from entering the shed.

Viruses and bacteria are everywhere. Preventing them in advance is the best way to reduce the risk of infection. Wearing a mask and washing hands frequently are crucial. The new type of coronavirus has the characteristics of contact transmission, and the fact that the virus exists on the doorknob of patients with pneumonia has also shown the necessity of paying attention to hand hygiene and wearing disposable protective gloves.
Whether it is going out to purchase daily necessities or buying through online platforms, it is inevitable to come into contact with "foreign" items, such as supermarket shopping carts, packaging bags, express packaging boxes, etc., and more things need to be touched after resuming work, such as It is inevitable to take public transportation, elevators, etc., these places may have been touched by patients or suspected patients. Wearing disposable protective gloves is an effective means to reduce the risk of infection when there is no condition to wash your hands at any time.
