Post-treatment measures of farmland waterlogging

1. Open trenches in time to drain water. For the land with stagnant water in the field, trench drainage should be carried out in time, and the trench direction should be trenched along the direction of crop planting, so as to prevent poor soil ventilation and cause dead seedlings.

two。 Reinforce and straighten in time. For lodging crops and so on, the soil can be strengthened in time, but it is not necessary to straighten the spring corn after pollination, so as to avoid stem fracture.

3. Strengthen the prevention and control of diseases. After the disaster, the stress resistance of crops is reduced, and diseases, insect pests and weeds are easy to occur. At the same time, insecticides, fungicides and micro-fertilizers should be sprayed on the affected crops to enhance their stress resistance.

4. Ploughing and loosening the soil to release moisture. After heavy rain, it will cause soil consolidation and cause anoxia and dyspnea in the roots. It is necessary to loosen the soil by ploughing in time, improve soil ventilation, increase root activity and prevent rotting roots.

5. Dressing up in time. After the disaster can cause soil de-fertilizing, should be timely topdressing, 5-10 kg of urea or 15-20 kg of nitrophosphate fertilizer per mu. Or spray with 1-2% urea solution or 100 grams of potassium dihydrogen phosphate with 30 kg water or other foliar fertilizers rich in N, P, K and various trace elements, spray 2-3 times at intervals of 7-10 days to prevent fertilizer deficiency.

6. Replanting and replanting. For the plots that have caused a bad harvest, we can quickly change the planting of mung beans, or we can change the planting of chrysanthemum, hollow cabbage, heat-resistant pakchoi and other vegetables, which will be harvested before the end of September and will not affect wheat sowing.
