After the crop suffers from a flood disaster, it is necessary to take timely remedial measures and strengthen field management to reduce disasters and ensure production. The specific approach is:
Timely elimination of water accumulation in the field According to the situation of the accumulated water and the topography, drainage machinery and digging drainage ditch are used to expel the stagnant water in the field and stagnant water as soon as possible to reduce the time of water accumulation in the field.
Timely finishing plants in the field After flooding and wind blowing, the root system is damaged, and it is easy to fall down. After draining, the water must be straightened and straightened, and the surface mud should be washed away to facilitate photosynthesis and promote plant growth.
When cultivating loose soils in timely cultivating soil, soil compaction, poor ventilation, serious imbalance of water, gas, and heat conditions must be ploughed early to remove compaction, ventilation, to prevent roots, while soil cultivation, to prevent lodging.
Timely application of quick-acting fertilizer crops after flooding, a large loss of soil nutrients, coupled with weakening of the root absorption capacity, timely dressing is very beneficial to restore plant growth and increase yield. Before the plants resumed their growth, they were sprayed with foliar fertilizers (eg, 0.5% to 1% urea solution, 2% to 3% calcium superphosphate leaching solution, 0.2% to 0.3% potassium dihydrogen phosphate solution, and Tianda 2116, Penshibao, Amino acids, etc.) are the main factors; after the plants are restored to growth, the roots are fertilized to reduce the loss of locusts.
Timely Prevention of Pests and Diseases After a locust plague, high field temperatures and high humidity, coupled with weak crop growth and reduced stress resistance, are suitable for a variety of diseases and pests. Investigation and control must be conducted in time to control the spread.
Timely change to other crops because of disaster. For the harvested plots, it is necessary to seize the season and timely rush to plant quick-growing vegetables or mung beans, red bean and other short-growing grains to maximize the losses. Where there are difficulties in replanting, after the water is drained, it is necessary to grasp the cultivation and water conservation to lay a good foundation for the planting of autumn and winter.
