Fruit trees can be protected from "cold spring"
"Cold spring cold" refers to the strong cold current that occurs between March and April. Fruit trees such as apricot, plum, and cherry that are flowering earlier are extremely vulnerable to "cold spring". So how can we avoid it?
Spraying the tree guard general: 25-30 days before the flowering of the fruit tree, spray the tree general 800 times liquid, can delay flowering for 3-5 days, because the cold current is only 1-2 days to end, can escape the cold current hazard.
Irrigation and lowering the ground temperature: Before and after fruiting, pay attention to listening to the weather forecast, watering before the cold current, lowering the ground temperature, slowing the growth of fruit trees, and delaying flowering for 2-3 days.
Smoke and cold protection: At 2-3 o'clock that night when the cold current comes, ignite the firewood around the orchard, rarely see the open fire, see more smoke, form a layer of smoke above the orchard, keep it until the sun comes out, to avoid the danger of cold current.
For fruit trees that have suffered from freezing damage, the following measures can be taken to minimize losses:
Artificially assisted pollination: Artificially assisted pollination should be carried out in time for flowers that are not frozen and are open. This is the first time to collect pollen and put it in the refrigerator for later use.
Strengthen the management of fertilizer and water: especially in the low-lying areas where the freezing damage is serious, we should pay close attention to the application of quick-acting nitrogen fertilizer, timely watering, promote the growth of fruit trees, and preserve the unfrozen flowers and fruits.
Foliar application of new high-fat film: After the occurrence of freezing damage, the leaves are generally not frozen, and the new high-fat film should be sprayed in time to prevent leaf virus infection, restore plant physiological vitality, and promote plant growth. The foliage is green, the photosynthesis product accumulation and directional transport capacity are enhanced.
