1. Antifreeze management　　

Frost is a serious threat to olives, especially the young shoots of young trees, seedlings and adult trees. Olives will suffer from freezing damage below -3°C. Therefore, we should do a good job of preventing frost in winter. Cover the branches with straw before the frost occurs to protect the shoots from frost damage, or use lime water to smear the tree trunks to reduce frost damage. Carry out soil cultivation before the frost occurs to thicken the soil. Layers, increasing the ground temperature can also reduce cold damage.　

2. Water management　　

After the spring, do a good job of ditching and drainage, preventing waterlogging and protecting roots, conducive to soil and water conservation, reducing the humidity of the orchard, and avoiding anthracnose and gum disease.　

3. Reasonable trim 　　

After the frost is lifted, clean the whole garden in time to clean the fallen leaves, cut the fallen leaves, dead branches, frozen branches, diseased branches, and senile branches. After germination in March, cut the larger bald branches appropriately for germination. New shoots. The pruned branches should be sprayed with 700 times thiophanate to protect the wound.　　

4. Deeply change the soil 　　

In mid-February, dig a depth of 25 cm around the canopy, and overturn the excavated soil block, that is, the original soil is facing down, the heart soil is facing up, and the soil block is not broken, sprinkle some lime to neutralize the acidity of the soil, and mix the soil. The compost piles into the soil.　　

5. Reasonable fertilization　　

Combined with deep soil modification, 100 kilograms of soil fertilizer and 20 kilograms of ammonium bicarbonate are applied to promote spring shoots, flower bud differentiation and fruit setting. Spray 0.05% borax in the spring flowering period to increase the fruit setting rate, and spray 0.3% urea and 0.2% potassium dihydrogen phosphate in the young fruit period to reduce fruit drop caused by frost damage.　　

6. Strengthen pest control　　

Spray 600 times of copper oxychloride before spitting buds, and spray it again after budding in spring and summer to protect new shoots from anthracnose. In the spring shoots, you should be alert to the occurrence and damage of Psylla sylvestris. Psylla 1200 times liquid can be used for prevention and control.
