How to remedy corn planting techniques in the event of flood disasters

Recently, heavy rains have occurred in most areas of China, causing floods in some areas. For corn planting, the sooner the corn seeds are germinated, the earlier the damage occurs, the longer the flooding time, the more severe the damage, the more flooding The deeper the reduction in production. Generally, the flooding is reduced by more than 20% in 4 days, and the plant is killed after being inundated for 3 days. Remediation measures should be taken as soon as possible after the occurrence of disasters in maize to minimize losses.

Drainage and waterlogging is the first priority. It is necessary to dredge the Tiantougou, the furrow and the lumbar sulcus, and timely eliminate the accumulated water in the field, reduce the soil moisture, and achieve the purpose of arranging and reducing energy.

Followed by cultivating loose soil. When the ground is white after precipitation, it is necessary to cultivate the loose soil in time, break the soil compaction, promote the soil to dilate and breathe, improve the rhizosphere environment and promote root growth. The lodging of the corn seedlings should be timely and righted up.

Again, it is early to apply seedlings. It is necessary to timely apply the seedling fertilizer, and apply 20 kg of urea per acre during the big bell period. For fields with long flooding time and serious waterlogging, high-efficiency foliar fertilizer and root-promoting agent should be sprayed at the same time as fertilization to promote recovery.

Finally, strengthen pest control. After the disaster, the corn is prone to various diseases and insect pests such as large and small spot disease and corn borer. When spraying foliar fertilizer, pest control can be carried out at the same time.

Zhengdao Fertilizer Network Tips: For the prevention and treatment of sheath blight, you can use Jinggangmycin or carbendazim spray. When spraying, focus on the stems and leaves below the ear; for the prevention and treatment of large-sized spot disease, you can use chlorothalonil or methyl thiophanate, 7 to 10 days. Once, 2 to 3 times in a row. The control of corn mash should be formulated into toxic soil or phoxim in the period of jointing to trumpet.
