Vegetable treatment after hot rain
Summer hot rain is the most harmful to vegetables. At that time, we should mainly do the following work.
When the heat storm has passed, it is best to organize artificial water splashing immediately, and water the place with cold spring water or well water to wash off the sediment adhering to the stems and leaves. To reduce soil temperature, increase soil oxygen, and keep vegetables in normal breathing state.
The hot rain caused the leaves to be covered with sand and affected the growth of vegetables. Only when the sediment adhering to the stems and leaves is washed away, and immediately correcting and reducing the mutual extrusion phenomenon, it is possible to make the vegetables grow normally.
After the hot rainstorm, the root activity of the vegetables was very weak, and the water absorption and absorption were poor. At this time, foliar fertilizer should be sprayed in time, and 1% of imported urea solution should be added to the leaf surface with potassium dihydrogen phosphate solution to enhance the ability to absorb fertilizer and quickly restore vitality.
After the water is removed, the soil should be ploughed in time, and the ash or spray of Bordeaux mixture should be applied before the dew is dried to prevent some diseases from infecting and large areas.
