For piles that are difficult to carry soil balls, special attention should be paid to the excavation season. The best mining season should be around 20 days before and after "beginning of spring". At this time, the sap of pine and cypress will germinate, but it has not yet begun to germinate. Cutting will not affect the loss of body fluids too much, and then the temperature will gradually increase, and the sitting posture will soon be restored, making it easier to survive. If the season is advanced, although the sap does not flow, the temperature is low and the recovery time is prolonged, which affects the recovery of the tree and makes it difficult to survive. Second, after excavation, we should reserve some branches and leaves according to the number of fibrous roots, leave more fibrous roots and leave less fibrous roots. The retention is mainly due to the imbalance of water supply and demand of roots and trees, otherwise it will affect the survival, because after beginning of spring, with the gradual increase of temperature, the sap will start to flow after planting. If the leaves are too short or too few, the sap will not circulate normally, and the wax grease in the epidermis will block the buds and prevent them from sprouting. Staying too long and too much water supply will also lead to death. In order to avoid water loss after sawing and reduce immunity, the incision should be sealed with white latex or plastic film, and the root incision should be leveled with a sharp knife. Third, the pile head should be excavated and treated in time before planting. It is best to start planting in the field. Choose old mountain soil with lean meat and good ventilation, and don't bury it too deep. It is suggested that the roots should be flush with the soil surface. Buried too deep will suffocate due to poor ventilation. Planting should avoid rainy days, but also pay attention to root irrigation, water the next day, shovel some garden soil to cover the roots after watering, then cut some branches with leaves and insert them around the roots to block some strong light to protect the feet from the sun, and then remove them after autumn. It is best to choose a place with good ventilation and no sun in the afternoon. Post-planting management should pay attention to keep the soil moist, and it is better to dry it slightly. Don't water the roots frequently after watering, which can increase the soil temperature and is conducive to rooting. When the sun is too strong, water should be sprayed on the tree and soil surface to adjust the temperature difference, which is beneficial to the germination of new roots and branches. Hot weather, moist and cool roots are easy to cause ants. When watering, you can water the dry tea once or twice or put the pesticide Funandan to kill ants. Pay attention to prevent rust after survival, and spray bactericidal pesticides such as "carbendazim" or "fenxiuning" on branches and leaves twice a year from the end of February to the end of March. The interval of application is 10 day, or a little insecticide such as "killing the enemy" or "dead net" is added, which is convenient to kill small green-shelled snails and prevent the bark of small shoots from being damaged. Pine and cypress trees have no other major pests and diseases, and are easy to manage after survival, and can be initially pulled out and reshaped after winter in the following year. Don't peel off the relics in a hurry, and then trim the shape when the branches grow to a certain thickness.
