How to Handle Farmland After Flooding? A Detailed Guide to Practical Remedial Measures

1. Open ditches and drain water promptly. For plots with standing water in the fields, open ditches promptly to drain the water. Run the drainage ditches between the rows, following the direction in which the crops are planted, to prevent poor soil aeration that can cause seedling death.

2. Reinforce and straighten plants promptly. For lodged crops and the like, once you can get into the field, promptly reinforce, straighten and earth up around them. Spring corn that has already been pollinated does not need to be straightened, to avoid breaking the stalks.

3. Strengthen disease control. After a disaster, crops have reduced stress resistance and are highly prone to pests, diseases, and weeds. Strengthen pest and disease forecasting and monitoring, and at the same time spray affected crops with a mixture of insecticide + fungicide + micronutrient fertilizer to enhance their stress resistance.

4. Cultivate and loosen the soil to release moisture. After heavy rain, the soil becomes compacted, causing oxygen deficiency at the roots and poor respiration. Cultivate and loosen the soil promptly to improve soil aeration, boost root vitality, and prevent root rot.

5. Topdress promptly. After a disaster, the soil may be depleted of nutrients, so topdress promptly. Apply 5-10 kg of urea or 15-20 kg of ammonium phosphate nitrate per mu. Alternatively, spray a 1-2% urea solution, or 100 grams of potassium dihydrogen phosphate dissolved in 30 kg of water, or other foliar fertilizers rich in N, P, K and various trace elements. Spray 2-3 times at 7-10 day intervals to prevent nutrient deficiency.

6. Replant or switch crops. For plots where the harvest has been completely lost, you can quickly switch to mung beans, or to vegetables such as garland chrysanthemum, water spinach, and heat-tolerant bok choy, completing the harvest before late September so that wheat sowing is not affected.
