How to remedy corn suffering from locust disaster:
First, timely elimination of the field of water,
According to the situation of water accumulation and topography, drainage machinery and digging drainage can be used to discharge the stagnant water in the field and the stagnant water in the ploughing layer as soon as possible to reduce the time of water accumulation in the field.
Second, timely consolidation of field plants
After the plants are flooded and blown by the wind, the roots are damaged and easy to fall. After draining, they must be straightened and straightened in time, and the surface sludge should be washed away to facilitate photosynthesis and promote plant growth.
Third, timely cultivating loose soil
After drainage, the soil is compacted, the ventilation is poor, and the water, gas and heat conditions are seriously dysfunctional. It is necessary to cultivate early to eliminate the knot, divergence and ventilation, to prevent rooting, and to carry out soiling to prevent lodging.
Fourth, timely increase in the application of quick-acting fertilizer
After the crops are flooded, the soil nutrients are largely lost, and the root absorption capacity is weakened. Timely topdressing is very beneficial to plant growth and yield increase. Before the plants resume growth, foliar spray fertilizer (such as 0.5% to 1% urea solution, 0.2% to 0.3% potassium dihydrogen phosphate solution) is mainly used; after the plants resume growth, root fertilization is carried out, and carbonic acid is applied per acre. Hydrogen ammonium 10-15 kg to reduce the damage caused by the disaster.
V. Timely prevention and control of pests and diseases
After the disaster, the field temperature is high and the humidity is high. In addition, the crops are weak and the stress resistance is reduced. It is suitable for a variety of pests and diseases. It is necessary to investigate and control in time to control the spread.
