How to manage vegetables after heavy rain? Detailed explanation of the latest technical points
Vegetables are an indispensable type of crop every day in our country. There are many varieties of vegetables in our country, such as gourd vegetables, leafy vegetables, etc., and different vegetables are distributed in different regions across our country. When growing vegetables, we need to do a good job in management, but it is inevitable to encounter some natural disasters that affect the growth of vegetables. The most common one is heavy rain, so how should vegetables be managed after the heavy rain? Let's take a look below!
1. Clear ditches and drain water
After the heavy rain, clear the ditches in time and remove the water in the ditches completely to ensure that water drains quickly when it rains and the ditches are dry when the rain stops. The ditch water on both the ridge surface and the bed surface must be drained in time. If the terrain is low-lying, a water pump can be used for drainage where conditions permit. Speed up the process and lower the water level in time. For flooded vegetable plots, the ground should be cleared to prevent vegetables from being submerged for too long and to reduce losses. Timely drainage can restore the root capacity of vegetables as soon as possible, avoid waterlogging damage, and reduce the phenomenon of vegetable death caused by accumulated water.
2. Vegetable management
Promptly straighten vegetables that have fallen over due to accumulated water to avoid pressing against each other, then carry out appropriate intertillage and earthing up, and spray an appropriate amount of foliar fertilizer. If the soil becomes compacted, loosen the soil in time, improve the soil structure, and restore root growth. Also water manually in time to wash the soil off the leaves, and be sure to ensure the water quality is clean. To avoid further damage, cover with film in time and set up rain-shelter facilities. Finally, avoid sudden clearing after rain, and do a good job of shading.
3. Replanting and changing crops
⟦NL>After the heavy rain, dead seedlings and missing seedlings will inevitably appear in the field. To ensure full and uniform seedlings, we must do a good job of replanting and changing crops. At the openings where seedlings are missing, replant with seedlings of the same growth stage in time. For vegetables such as peppers, eggplants, and cucumbers, autumn seedling raising should be carried out immediately to avoid expanding the damaged area. Then pay attention to avoiding secondary disasters brought by heavy rain, such as mudslides and landslides. Check the condition of greenhouses and reinforce the greenhouse legs to prevent secondary disasters from causing further damage to vegetables.4. Pest and disease control
If the heavy rain occurs in summer, then after the heavy rain we also need to pay attention to doing a good job in pest and disease control. Because the high-temperature and high-humidity environment can easily trigger various pests and diseases. Moreover, after experiencing heavy rain, the resistance of vegetables is also very poor, so pesticides should be sprayed in time to prevent the occurrence of pests and diseases. In addition to doing a good job of drainage and cooling, we should also appropriately spray agents such as carbendazim and deltamethrin to inhibit the development of pathogens and reduce the incidence of vegetable pests and diseases.
The above is a brief introduction to how to manage vegetables after heavy rain. Management of vegetables after heavy rain is very important, because some losses have already been suffered. At this time, what we need to do is reduce losses as much as possible and protect planting benefits. That is all for today's introduction. This article is for reference only.
