Management measures after crops are affected
Damage refers to damage caused by excessive soil moisture to crops. The occurrence of aphid damage is due to low-lying terrain, heavy soil, and poor drainage. Second, in the season of long rainfall or excessive rainfall, there is an excess of surface water and groundwater that cannot be discharged for a time; crops with high groundwater levels and poor drainage are vulnerable to damage. Then there is flooding in the flood season and the damage caused by the water flow on the slopes. In short, if the amount of water is too large and drainage is not done well, it will cause damage. After a crop suffers from a locust plague, it is necessary to take timely measures to strengthen field management in order to reduce disasters and ensure production. The specific approach is as follows.
Exclude water in the field in time According to the situation of water accumulation and the topography, drainage machinery and digging drainage ditch are adopted to expel the stagnant water in the field and stagnant water as soon as possible to minimize the time of field water accumulation.
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, the main spraying fertilizer (such as 0.5%-1% urea solution, 0.2%-0.3% potassium dihydrogen phosphate solution, etc.) was dominant; after the plants resumed growth, the roots were fertilized to reduce the loss of the disaster. .
Timely Prevention of Pests and Diseases After the disaster, the high temperature in the field, high humidity, coupled with the declining crop growth, reduced resistance, suitable for a variety of pests and diseases, timely investigation and control, control of spread.
To timely replant the fields where other crops have been destroyed due to floods, we must seize the season and timely plant crops with short growing periods such as fast-growing vegetables to maximize the losses. Where there are difficulties in replanting, after the water is discharged, it is necessary to grasp cultivation and water conservation to lay a good foundation for the autumn crops.
