Oranges, as a characteristic fruit in the southern region of our country, are deeply loved by people. With the expansion of planting areas, orange trees are also beginning to be planted in the northern region. However, due to the cold winter in the north, how to keep orange trees safe during the winter has become a focus of many fruit farmers. This article will introduce you to the methods of keeping orange trees in the north safe during the winter, helping your orange trees to safely pass through the cold winter.
Choose suitable orange tree varietiesThe climate in the northern region is cold, and the suitable varieties of orange trees for planting are limited. It is recommended to choose orange tree varieties with strong cold resistance, such as Xuegan and Nanfeng蜜橘 (Nanfeng honey oranges), which grow well in the northern region and can adapt to the cold climate.
Strengthen autumn management1. Fertilization: Autumn is a key period for the growth of orange trees. An appropriate amount of phosphorus and potassium fertilizers should be applied to promote the growth of orange trees and the maturation of fruits.
2. Pruning: Autumn pruning can remove diseased and weak branches, dense branches, improve the ventilation and light transmission of orange trees, and help orange trees to survive the winter.
3. Pest and disease control: Autumn is a high-incidence period for pests and diseases. It is necessary to control them in a timely manner to reduce the harm caused by pests and diseases to orange trees.
Insulation coverage1. Soil coverage: Laying稻草 or leaves around orange trees can increase the insulation capacity of the soil and reduce the risk of frost damage.
2. Trunk smearing: Smearing the orange tree trunks with lime water can prevent frostbite and enhance the cold resistance of orange trees.
3. Spraying antifreeze: Spraying antifreeze on orange trees before the arrival of winter can enhance the cold resistance of orange trees.
Reasonable irrigationThe water requirement of orange trees in winter decreases, so the frequency of irrigation should be reduced, keeping the soil moist, and avoiding excessive watering that may damage the roots.
Strengthen winter inspectionsThe winter temperature is low, and orange trees are easily affected by frost damage. It is necessary to strengthen inspections, and take timely measures when frost damage is found, such as pruning frozen branches and spraying growth regulators.
Keeping orange trees in the north safe during the winter requires a series of measures, including choosing suitable varieties, strengthening autumn management, providing insulation coverage, reasonable irrigation, and enhancing winter inspections. Only by doing these tasks well can orange trees safely survive the winter and lay the foundation for a harvest in the following year.
