Choose the right tree species according to local conditions. Planting varieties and rootstocks with strong cold resistance, and selecting marginal tree species with low cold resistance in areas with good microclimate conditions. At the same time, attention should be paid to planting shelter forests and setting up wind barriers to improve microclimate conditions.
Strengthening cultivation management helps to preserve the nutrients in the tree. In the spring, we will strengthen the supply of fertilizer and water, rationally apply irrigation and fertilization techniques, increase the accumulation of nutrients, and ensure the robustness of the trees. In the summer, the heart is topped to promote the ripening of the branches. In autumn, irrigation, timely drainage, appropriate use of phosphorus and potassium fertilizer, diligent and deep tillage, promote the early termination of shoot growth, is conducive to tissue enrichment and prolong the accumulation of nutrients. Winter pruning to reduce transpiration area, artificial leaves, etc. have a good effect on preventing freezing damage. At the same time, strengthen the prevention and control of pests and diseases.
Strengthen tree protection. General trees can be controlled by pouring "frozen water" and irrigation "spring water". For the types that are easy to be frozen, the whole plant can be sprayed with trees to prevent and prevent freezing. In order to avoid the early arrival of low temperature, causing freezing damage.
The fumigation method is antifreeze. At about 2 o'clock in the middle of the night, the grass pile or chemical is ignited on the wind, and the smoke is used to prevent frost. This method is simple, economical and effective. (Dani)
