Transplantation of wild poinsettia is generally chosen in the yellow plum days or 11-3 months. 1, the choice of soil and processing:,poinsettia To choose aeration, good permeability, water retention and fertilizer capacity, soil water, fertilizer, air, heat condition coordination of the soil. With sand mixed with loess (3:1 is better) as a transplanted planting soil is better, it has three major benefits, one is with the roots of the tree has "affinity". In the cultivation of large trees, roots and soil often can not be compacted gaps, the erosion of rain, sand mixed with loess easy to stick with the roots; Second, good aeration. It can increase the ground temperature and promote the sprouting of the root system, and the third is good drainage. Rainy season can quickly drain off excess water. Free from water compost, resulting in root death, dry season watering can be quickly absorbed and spread.　　In the excavation process to selectively retain a portion of the original soil between the roots of the tree, in order to facilitate the sprouting of trees. At the same time must be half a month before the transplanting of trees in the hole soil sterilization, deworming treatment, with 50% tolbutazin or 50% carbendazim powder mixing soil sterilization, with 50% surface Wei-granules mixing soil to kill insects (the proportion of the above agents mixing soil for 0.1%).　　2, transplanted after the water, fertilizer management: A, dry season management: June-September, thousands of toon prices, most of the time the temperature above 28 ℃, and humidity is small, buy lilac, is the most difficult management period, begonias. The management of this time to pay special attention to: one is the shade sunscreen, persimmon tree, can be the periphery of the canopy east-west direction to take "a few" type, cover the shade net, which can better block the sun's direct light, so that the leaves from burns; the second is the root of the irrigation, hinoki cypress prices, letter of pre-buried plastic tubes or bamboo tubes within the irrigation, this method can be avoided watering "half water", the price of acacia, can be watered through, usually make the soil see the dry see the wet, can also to the Cave irrigation outside the canopy, increase the humidity of the soil around the trees, purple leaf dwarf cherry; three is the tree south set up a triangular bracket, install a high tree 1 meter sprinkler, try to adjust to the fog water, because summer and fall mostly blowing south wind, installed in the south can often give the canopy spray water to the tree trunks and leaves to keep wet, but also increase the humidity around the tree and reduce the temperature, reduce the trees in the body of the limited water, nutrients Consumption.　　No conditions can be used when the "drip irrigation method", that is, a tripod next to the tree, hanging a water storage bucket, in the lower part of the bucket to play a number of holes, with silica gel will be glued to the hole in the plastic tube, the other end of the fire after sealing the tube spiral around the trunk and branches, according to the needs of the direction from the tube on the holes to the dripping, the same can play a role in moistening the trunk tree, reduce the consumption of water and nutrients.　　B, the management of the rainy season: southern spring rain, air temperature, this time the main should be anti-flooding. Due to the first buds and leaves of trees, root wounds have not healed, often into the death of trees. Rainy season with submersible pumps to drain the hole one by one, to avoid trees being waterlogged.　　C, the management of the cold season: to strengthen the cold, warmth measures. One should use grass rope around the dry, wrapped warmth, so that can effectively low Royal low temperature and cold wind infringement, the second is to build a simple plastic film greenhouse, to improve the temperature and humidity of the trees, the third is to choose the day the temperature is relatively high at noon watering or foliar water spraying,hollister france.　　D, after transplanting the fertilizer: due to the tree damage, the first year can not fertilize, the second year according to the growth of the tree farmyard fertilizer or foliar spray fertilizer, ruby begonias.　　3, after transplanting the prevention and control of pests and diseases: trees through the saw cut, transplanting, wounds, sprouting tree leaves tender, the tree's resistance is weak, easy to suffer from disease, pests, so to strengthen the prevention. Can be sprayed with a mixture of pesticides such as carbendazim or tolbutamide and dichlorvos. Divided into three stages in April, July and September, each stage of continuous spraying of this medicine, once a week, under normal circumstances can be achieved.
