Drainage dredging: Corn is a crop that requires large amounts of water but is not tolerant to flooding. The longer the flooding time, the heavier the damage, the deeper the flood, and the heavier the reduction in production. Therefore, in the case of waterlogged flooded plots, the gully drains and gutters should be dredged and the water in the fields should be drained quickly. The water can't be drained by the drain, and the water can be drained by water pumps or artificial water to reduce the soil moisture.
Scientifically assisted seedlings: When the maize seedlings fall flat below 30, the corn should be gently lifted in the opposite direction of lodging, and the foot should be stepped on the soil in the roots of the corn in the opposite direction. Do not step on the lodging position. Due to the fragile nature of the 1~2 internodes of the base of the corn stem and the damage to the existing root system, it is necessary to prevent breakage and increase the number of new root injury when supporting the seedlings. The plots with more than 60 degrees of lodging can naturally recover due to the adjustment ability of corn itself. Lodging in the field of 30 ~ 60, supporting the seedling soil, promote corn to support root production.
Follow-up fertilization materials: the roots of lodging corn are subject to certain damage, unfavorable absorption of nutrients and water by the plants, combined with soil compaction, poor ventilation, will delay the growth rate of corn, resulting in late maturity. Should be combined with cultivator, topdressing 10 kg of urea per mu, potassium chloride 10 kg, and promote its recovery as soon as possible.
Plow replenishment: For fields with serious disasters and no hope of remediation, it is necessary to reclaim the plough in time to make up for the losses caused by the disaster. You can choose to plant some fast-growing leaf vegetables, such as chicken feather vegetables, small green vegetables and so on. Plowing replanting plots, to grab the time for early sowing, increase phosphate fertilizers, strengthen management, and promote early maturity.
