Research On Artistic Expression Of The Force Feeling Created By Torsion In Bonsai And Its Application In The Creation Of Small Tree Bonsai

Bonsai,as a traditional literati art,has a long history of development.The force feeling created by torsion is a special form of power sense of tree bonsai,and is an effective means to enhance the artistic appeal of bonsai.The research and creation of torsional bonsai is a hot topic of bonsai creativity and innovation.At present,the research on the system theory of torsional force sensation is still in a relatively blank stage,and the creative practice lacks theoretical support.Therefore,in view of this situation,through in-depth research on theory and practice,in this paper,relevant concepts are defined,relevant theoretical system is improved,and the following main achievements are formed:1.The related concepts of the force feeling created by torsion and torsional bonsai are clarified.In bonsai trees,local branches,stems,roots and other parts of the twisted visual dynamic resulting in a sense of force,called the force feeling created by torsion.Under natural or artificial action,the bonsai with twisted visual image and dynamic sensory effect is called torsional bonsai.The force feeling created by torsion in bonsai is related to dynamic force of bonsai,so the creation of the force feeling created by torsion in bonsai has important practical significance.2.The expression form of the force feeling created by torsion in bonsai can be classified from three aspects: torsional cause,torsional position and the type of deformation structure.According to the causes of torsion,it can be divided into natural torsion and artificial torsion.According to the torsion position,it can be divided into root torsion type,stem torsion type,branch torsion type and multiple torsion type.According to the type of deformed tissue,it can be divided into noumenon torsion and appearance torsion.According to the texture type,the appearance type can be divided into bark texture twist type and natural sacrificial trunk twist type.Body torsion can be divided into traumatic torsion and non-invasive torsion according to trauma morphology.Traumatic torsion of branch can be divided into cleft trunk torsion and split trunk torsion according to the processing mode.According to the axis variation,the non-invasive torsion type can be divided into straight torsion type and bending torsion type.3.With the help of "torsional angle","torsional amplitude","torsional length","torsional cylinder number" and other quantitative indicators,the grades of torsional strength for different torsion types are defined.Appearance torsion can be divided into mild torsion,medium torsion and high torsion by the number of torsion turns.Body non-invasive torsion with “torsional amplitude”,“torsional angle” as the main indicators,divided into mild torsion,medium torsion,high torsion and super torsion.noumenon traumatic torsion can be combined with different processing methods according to the appearance torsion and body non-invasive torsion strength classification.4.The aesthetic characteristics of torsional force expression in enhancing bonsai form,texture,color,dynamic and emotion are studied.At the same time,the four functions are researched,such as changing the line shape of branches,helping the branches to bend,shaping bonsai aging,enhancing bonsai power and momentum,creating visual beauty point and so on.5.Main four processing techniques about the force feeling created by torsion are summarized and practiced,such as the method of twining young shoots,the method of winding twigs,the method of longitudinal crack and twisting branches of conifers and the method of texture of sacrificial trunk representation.In the process of creation,five key links are necessary to be grasped,such as selecting the material and the time,looking at the material and clearing form,designing the torsion,modelling and later maintenance...
