Seedlings of winter pruning pruning time and skill (dormant pruning) is mostly deciduous trees pruning period, and should be in the spring before the leaves sprout tree began to be dormant. Seedlings slow physical activity during this period, most of the leaves return nutrients trunk, roots, nutrient losses caused minimal pruning, wound infection is not easy, little effect on seedling growth. Specific time pruning back trees and shrubs Xing, according to the local winter depending on the characteristics of the specific temperature, such as in the winter cold of the northern region, after pruning wounds susceptible to frost damage, trees and shrubs company, it is advisable to prune in early spring, trees and shrubs Sales , typically in the spring, before the sap flow for about two months time; and some need to protect winter flowering shrubs should be immediately re-cut in the autumn leaves, then wrap the trunk buried or cold. For some bleeding phenomenon of species, such as grapes, bleeding should begin in the spring before pruning. Bleeding is the body of nutrients and water the seedlings at the nursery wound drain phenomenon, the loss of too much will cause weak grower, and even dead branches. Some species bleeding appeared earlier, such as walnuts, began in mid-November after leaves, the best pruning time should leaves turn yellow before to after the harvest, and can mixed buds can promote, but If for planting or rejuvenation needs, pruning may be conducted before planting or early spring. Winds on seedling growth and development of wind damage is mainly caused by the typhoon, thunderstorm winds (hurricanes) and tornadoes. Effect of high winds on seedling growth mainly in the following aspects. Mechanical damage: high winds mean instantaneous wind speed reaches or exceeds 17m / s or 8 wind, make seedlings lodging, off dry, snags, broken leaves, leaves, fruit drop and reduce fruit quality and so on. Physiological hazards: strong winds can accelerate transpiration, causing stomatal closure, photosynthetic intensity decreases, leading to drought damage, chilling or freezing in winter, resulting in weak grower, metabolic disorders. 3) Sandy planting seedlings winds can cause shifting sand buried dry, exposed roots and torn leaves, affect flowering pollinator activities; stigma sticky or dry sand, reduce fruit set.
