Abstract

The invention discloses a quick cultivating and planting method for large crape myrtle landscape trees. The quick cultivating and planting method is characterized by comprising the following steps: selecting a perishable weed-tree pile which is nearly 2m in height, 0.2-0.4m in lower-end diameter and 0.15-0.35m in upper diameter as a tree shaft model; firmly around the tree shaft model, planting un-branched crape myrtle trees of 2-3 years in the soil, wherein the adjacent trunks are close to each other; using a plastic film to firmly cover and fix the trunks on the tree shaft model; removing the film in late June of the year, using a new film to recover the trunks in the late autumn, removing the new film in late June of the next year; and covering the trunks for another time by another new film in the late autumn, and removing the coating and the bonded films in the late June of the third year; and carrying out nutrient and water management according to a normal management method of an artificial cultivation method of crape myrtle during the whole cultivating and planting period. The quick cultivating and planting method can quickly cultivate large crape myrtle landscape trees within three years; the diameter at breast height of the trees can be designed by pre-selecting the diameter size of the model shaft model; the cultivated and planted large landscape trees are smooth and upright in trunks; the main branches are good in modelling; and the planting and cultivating survival rate is 100%.
