After the water recedes, it is necessary to quickly open the ditch, remove the underground water, and promote root growth. It is necessary to loosen the soil in time to promote the recovery of the strawberry. For the strawberry beds with severely damaged or dead roots, the pastoral area should be cleared in time, and 25-30 kilograms of lime should be used to finely dispose of the soil and replant or replant other cash crops.
Second, understand the disaster situation, classification guidance
For some heavily inundated strawberries that still have the ability to absorb roots, they can be cut off by dense branches and leaves or shaded by shade nets to prevent sun exposure, reduce transpiration, and prevent wilting due to physiological water loss. Partial yellow leaves, rotten leaves, and old leaves can be cut, and appropriate cultivators, soils, and vines can be used to promote root development and restore plant growth. When the water recedes, the leaves are washed with water in a timely manner. Since strawberries are still exposed to high-temperature and strong light before colonization, After the flooding, the resistance was poor. After the cleaning, the shade net was used to shave and reduce heat in the field.
Third, strengthen fertilizer and water management, restore the growth of vegetable seedlings
After the strawberry seedbed is flooded, nutrients are easily lost. Therefore, nitrogen, phosphorus, potash fertilizer and other compound micronutrients should be applied in a timely manner. Attention should be paid to the fact that it should not be emphasized or excessive in fertilization. Otherwise, it is easy to cause fertilizer damage, so fertilization should be appropriate. At the same time, we must combine cultivators. While doing a good job of soil fertigation, fertilizers can be applied outside the roots.
IV. Comprehensive Prevention and Control of Diseases and Insects, Reduction of Losses After the floods, it is very easy to aggravate anthrax and other diseases. Therefore, it is necessary to spray pesticides and insecticides in time for different species and damages after retreating, but pay attention to the use of low toxicity, low residue, and high efficiency. Pesticides to ensure the safety of strawberries.
V. Arrangements for post-production
For fields that have been flooded for too long and the seedlings have already died, timely replanting or replanting should be arranged. After the water recedes, it is necessary to timely disinfect the lime, and then snatch up the clear ground and arrange the sowing time. Priority can be given to arranging varieties with short growing period, rapid growth and high yield to ensure a balanced market of strawberries and meet the needs of the citizens.
First, clean up the gully and remove the accumulated water
