Because the strawberry root system is shallow, it is basically ridge cultivation. Once it is flooded for more than two days, it will easily cause root growth. It will not be fully drained for more than four days. Therefore, once flooded, the first time The water should be removed.
Eliminate stagnant water and clean up the ravine. After the large water recedes, it is necessary to quickly drain the water and drain the water in the field. If there is a condition, a comprehensive disinfection treatment can be carried out to prevent the infection of the disease after being flooded. At the same time, it is necessary to loosen the pine ridges in time, or ridge the ridges to promote root growth. After flooding, the most important thing is to promote the breathing and links of the root system, so the loose soil is very important, and the roots, dead trees and yellow leaves and fruit stems are removed. For unsustainable fields, it is recommended that all rice fields or other crops be replanted after they have been cleaned up.
Trim in time to promote growth. After the accumulation of water, management according to the field conditions, flooded fields, timely cutting off the dense branches and leaves in the above ground, reducing transpiration, preventing wilting caused by physiological dehydration; at the same time reducing yellow leaves, rotten leaves, old Leaves, proper cultivating, cultivating soil, pressing vines, promoting root development, restoring plant growth, and rinsing the foliage with water in time. Let the leaves restore photosynthesis and make nutrients.
Timely fertilizer management, comprehensive prevention and control. After the strawberry is flooded, the root respiration and nutrient absorption are reduced, and the large and medium amount of elemental fertilizer is replenished in time. The principle of multiple supplements is adopted, and the supplement should not be excessive at one time, otherwise it will cause fat damage, and combined with cultivating, fertilize the soil. At the same time, it can be used for top dressing.
Pull the shade net and spray it to cool down. After the rain, it will be sunny. If there are conditions, the sunshade net will be pulled in time to avoid the phenomenon of roasting due to strong light. If the heart leaves are found to be coke, dry and black, basically the young leaves will be excessively dehydrated after the rain. It causes a wilting and dry phenomenon. This symptom is acute and non-infectious. As long as the field management is strengthened, it can be avoided. The shade net can be added in the field to reduce the light intensity and reduce the transpiration of the leaf surface, thereby reducing the water loss of the leaves and reducing the wilting phenomenon. At the same time, water spray treatment in the field can not only reduce the temperature in the field, but also help the leaf surface to replenish water and reduce the wilting caused by strong light.
Prevent disease and cure insects and reduce losses. After being flooded, the strawberry is prone to disease, focusing on the prevention and treatment of "two diseases and two insects" - root rot, anthracnose, Spodoptera litura, and red spider. After the seedlings are slowed down, prevent them in time. After the strawberry is damaged, it must be strengthened in time to reduce losses.
