A few days ago, after the rainy weather, the author came to Dongling, Jiangjiazhuang Village, Yanqiao Town, Pingyi County, and saw that Jiang Shenggang, a large planter in the town, was rowing corn. Based on years of planting experience, Lao Jiang summed up the scientific “Fangzi” of the drainage, specifically to pay attention to the following aspects:

Drainage dredging

Corn is a crop that requires a lot of water but is not resistant to cockroaches. The longer it is flooded, the heavier the damage; the deeper the flood, the heavier the yield. To this end, for heavily flooded fields, the ground drains and waist ditch should be dredged in time to quickly discharge the accumulated water in the field; the fields that cannot be drained by the canals are pumped or artificially drained to reduce soil moisture.

Science

For the field where the corn seedlings fall below 30 °, the corn should be gently lifted in the opposite direction of the lodging, and the corn root soil should be stepped on in the opposite direction, and should not be stepped on the lodging direction. Because the base of the corn stem is relatively fragile between 1 and 2 knots, and some of the roots are damaged, it is necessary to prevent breakage and increase new root wounds when the seedlings are planted; the field with the lodging degree above 60 °, because of the adjustment ability of the corn itself, It can be restored naturally; in the field of 30 ° ~ 60 °, it is necessary to support the seedlings and promote the production of corn roots.

Scientific topdressing

The roots of the lodging corn are damaged, and the absorption of nutrients and water by the plants is unfavorable. In addition, the soil compaction and poor ventilation will delay the growth rate of the corn and lead to late ripening. It should be combined cultivator acre topdressing urea 10 kg, 10 kg of potassium chloride, and promote its back to life as soon as possible.

Turn plow sowing rush when reseeding    For land with serious disasters and no hope of remediation, it is necessary to timely re-cultivate the plough to make up for the losses caused by the disaster. You can choose to plant some fast-growing leafy vegetables, such as chicken and green vegetables. The plots replanted by the plough should be rushed to early sowing, increase the application of phosphate fertilizer, strengthen management, and promote its early maturity.
