| With the aging of the orchard age trees as the research object,the research on Application of ornamental fruit trees,old pile waste,processed through the art of modeling,for city greening,can not only meet the viewing needs,but also can improve the ecological environment,a new way of sustainable development for the development and utilization of the aged orchard.Study to change "the cultivation objective cultivation object will change with the production of fruits,fruit trees for cultivation purpose within the orchard for the application of city greening ornamental trees" as the goal,according to the age based aging orchard inherent artistic style,in the light of its general trend,transformation and variety improvement in shape,which is in accordance with the landscape Requirements.Old orchard site conditions,management level differences,differences based aging stumps,some transformation is difficult,requiring management after molding,after transplanting trees not flourishing,the ornamental effect is poor,therefore,the best choice of the relatively good foundation,age in 20~25 years old trees is ideal.In this study,25 year old apple as the stock,with Europe and the United States in the series of Begonia scion,the other at the same time,the circular cutting,promote new roots,ensure the survival rate of transplanting,through practice,the successful implementation of the transformation of old trees for the design of landscape trees,the successful completion of the test requirements;according to the old pile transformation experiments established The reference technical measures for the transformation of old trees into the landscape trees.Technical measures for the transformation of old trees into ornamental trees:(1)modification cycle: 3~4;(2)grafting method: high grafting is the best grafting method.After surviving the interface healing firm,strong wind resistance.Each scion bud 1~2,germination rate and branching ability are strong.Number: 20~25 years old grafted trees in 3~5 group have more ornamental branch group,35~45 per plant grafting scion.(3)grafting requirements: to ensure that the survival rate of grafting in 90% or more,then the percentage of branches in the 70~80%.(4): to trim storage branch stub.In other manipulations during the summer pruning with at least 4~5 times.Make sure each scion can naturally or by pinching out more than 2 in the next year to ensure short branches,total branches number reached more than 400,three years total quantity of branches reached about 1000.(5)before transplanting root: to ensure the survival rate,in the early construction of the two methods of promoting circular cutting stage,a new underground root.Establishmentof growth on the new balance,the transplanting survival rate was above 96%.(6): 25 years old transplanting acupoint transplantation of plug size 80 x 80 x 60 cm,per hole wall put 3~4 on the bottom of the airway,laying 20 cm thick sand as drainage layer,soil covering.Old trees pile ornamental exploitation and cultivation management technology,technicians and farmers experienced mostly can grasp,but the original fruit producers are unable to master the art of shaping methods in the process of art in.Must be under the guidance of professionals,the original farmers in modified skill training,training other professional and technical personnel,improve the fruit shape technique,the results of the promotion of the use of line of order can pass the advantage,become the fruit industry increases the growth point of economic income,to beautify the environment,brightening luster.The fruit is mainly aimed at the production of fruits,such as high-yield ability lost due to aging,will lose economic value.Through the integer transform for landscaping,trees turned into ornamental trees,improve economic value,aging out of the old fruit market price is 0.08~0.10 yuan / kg,20~30 years old only income 15~20.After the reconstruction of forming ornamental trees,the market price of 2500 yuan,per plant three years of cultivation cost about 100 yuan,transplanting,shipment,packaging costs 400 yuan,net profit per plant up to 2000 yuan,significantly improves the old trees The significant social and economic benefits are significant in the area of fruit tree planting. |
