1, increase the temperature. After the cucumbers in the greenhouse are frozen, we must first raise the temperature of the soil and promote the germination of new roots. We can open the mulch around the rhizosphere so that we can fully see the heat and accelerate the temperature rise.
2, timely plastic surgery. Cut off the frozen parts of the cucumber, including the leaves and some stalks, and create conditions for sunlight to reach the roots and promote recovery.
3, spraying regulator. Alizarin lactone 1000 times + tetracycline 300 times, improve the ability of plant self-repair, the emergence of lateral branches of leafhoppers, wound healing faster.
4, strengthen fertilizer and water management. To be restored to a certain degree of damage to the plant, when the new shoots start to grow, its individual fertilizer control, water soluble fertilizer with a good nutrition solution, each strain is poured about 100 ml, with a small amount of rooting agent or biological agents.
