In order to improve the survival rate of autumn planting seedlings, there is no frost death or draining, and relevant antifreeze measures must be taken.
Buried in the cold before the beginning of winter, the top of the seedlings planted in autumn will be bent down, and a small mound of 10-30 centimeters thick will be kept cold. After the soil thawed in the spring of the following year, the seedlings were unearthed and straightened, and the tree plates were repaired.
Before pouring frozen water around mid-November, you should pour frozen water once. It should not be too late. Because watering is too late, the temperature in winter is low, and the temperature rises slowly, which is not conducive to the root system to promote new roots, nor is it conducive to safe wintering.
After the entire plate covered with water in the fall, the soil should be loosened and flattened, and then the saplings should be made into a shallow disk shape and cover a width of 80 to 100 cm. Pre-winter coating can significantly delay the temperature drop, increase the temperature and protect the cold, resist drought and moisturize, and also enable a large number of new roots to occur before the winter and before sprouting in the young trees.
Set the dry bagging at the full shoots depending on the thickness of the seedlings, and then put on a plastic bag 50 to 90 cm in length and 10 cm in width to put warm clothing on the young trees. In the spring of the following year, as the temperature continues to rise, the air vents will be gradually increased. When the sprouts grow to 10-15 cm, they will all be removed.
Wrapped seedlings can be made of wheat straw, straw rope or a 6 cm wide plastic strip cut from a thin film with a thickness of 0.008 cm. From the bottom up, the seedlings can be tightly packed. Generally, two layers are appropriate to prevent freezing and prevent hares. Foraging bark.
If the smoke or the cold is affected by cold smoke or cold current, the fire smoke can be set in a short time depending on the size of the orchard and the direction of the wind.
