How to treat vegetables after the storm

The climate in summer is changeable, and the growth of vegetables is highly susceptible to climatic conditions. In the hot and rainy seasons, hot rains often attack crops, which is the most harmful to vegetables. After the hot rain, the stems and leaves of the vegetables were adhered by the sediment on the ground, and the pores on the leaves were blocked, which seriously affected the breathing, transpiration and photosynthesis of the vegetables. In addition, the vegetable plants that were hit by the hot rainstorm were boasted, the stems and leaves were easily broken, the soil was compacted, and the air in the soil was significantly reduced, causing the roots to be forced to undergo anaerobic respiration, resulting in cell death. In addition, after the hot rainstorm, the resistance of vegetables is weakened, which will cause the occurrence and spread of diseases, causing incalculable losses. Therefore, meteorological data should be collected at any time, and early preventive measures should be taken to minimize disaster losses. So how do you treat the vegetables that have been attacked by the hot rain? According to the research of agricultural technicians, the following protective measures should be taken.

Take remedial measures: splash water or cold spring water or cold well water in time. When a hot rainstorm occurs, it is best to organize artificial water splashing immediately. In places with cold spring water or well water, it is best to water it to wash off the sediment adhering to the soil to reduce soil temperature, increase soil oxygen, and keep vegetables. Normal breathing state. Eliminate accumulated water in time, dredge or deepen the vertical and horizontal drainage ditch, so that the drainage is smooth. Timely re-cultivation, loss of vegetable fields, consider re-seeding vegetables, and choose early-ripening vegetables such as Chinese cabbage and rapeseed that sprout well under moist soil conditions and have short growing days.

Implementing the Qingyuan: Clean up the leaves of the vegetable garden and avoid the spread of the disease. Timely organize artificial sand washing and correct the plants. 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.

Replenishing fertilizer: Foliar fertilizer is sprayed in time. After the hot rainstorm, the root activity of vegetables is very weak, and the water absorption and absorption are poor. At this time, foliar fertilizer should be sprayed in time, and potassium leaf dihydrogen phosphate solution should be added to the surface of the leaf by adding 1% of imported urea solution to enhance the ability to absorb fertilizer and quickly restore vitality. At the same time, 15 kg of urea ( or 30 kg of ammonium sulphate ) and 4 kg of potassium chloride can be applied per 10 mu for topdressing to promote development; vegetables are prone to downy mildew, powdery mildew or soft rot after the disaster, and should be strengthened and timely sprayed. 72.2% Plex water agent 600 times or 69% Anke-manganese zinc wettable powder 500 ~ 800 times liquid to prevent disease occurrence.

Cultivating and cultivating soil: After the topsoil is dried, the cultivating is carried out, and the soil is properly cultivated and the plants are adjusted to promote normal development. Timely cultivating loose soil and controlling pests and diseases. 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 the infection and the occurrence of the disease.
