Drainage and 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 plots that cannot be drained by the drains should be drained by water pumps or artificial water to reduce the soil moisture.
Science support 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. Suppresses the growth of the reverse bearing roots, promotes the growth of aerial roots in the fallen bearing and lowers them, and fixes the plants on their own roots. 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 their ability to adjust themselves. Lodging in the field of 30 ~ 60, supporting the seedling soil, promote corn to support root production.
The recovery of the roots of the corn planted with fertilizers will cause certain damage. The unfavorable absorption of nutrients and water by the plants, combined with poor soiling and poor ventilation, will delay the growth of corn and cause late maturity. Should be combined with cultivator per acre 10 kg of urea, potassium chloride 10 kg, promote its recovery as soon as possible.
Plow plough reseeding should provide timely reversal of ploughing and remedy the damage caused by disasters in fields where the disaster is serious and there is no hope of remedy. 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.
