Modeling design of pine and cypress bonsai: according to the characteristics of human landscape and pine and cypress, cut off the thick branches and vegetables of old stems and reduce the trunk and crown; Then the method of coarse binding and fine trimming is adopted to make the crown follow the natural shape and stagger layer by layer. There are small changes among the major levels, which have a sense of integrity, are not messy, and have the beauty of natural formation. We make full use of the resources of dwarf wild piles, adopt grafting methods such as grafting, belly grafting and bud grafting, and replace the crown with five-needle pine. Using abundant pine and cypress stump resources, the crown of cypress bonsai such as Jackie Chan and Bai Cui was grafted and replaced, forming a unique pine and cypress bonsai style.

(1) On the basis of the original technology, it also absorbs the advantages of other places, adopts the iron wire binding and shaping method, selects the iron wire with the corresponding thickness according to the thickness of the branches, and hangs the branches at an inappropriate angle to meet the needs of shaping. Trunks and thick branches that are not easy to bend by wire and suspension can be bent by finger insertion method which has been successfully tested for many years. If it is a big and thick branch, you can cut the upper part of the part that needs to be bent to half the depth of the diameter with a knife, and the length depends on the need. Cut several strips in this way, cut off the heads of the separated strips horizontally, and turn the other ends around. If you bend hard, the transverse decapitation will tilt upward, just like inserting your hands diagonally. After the main branch or trunk is fixed, the upturned part can be embedded in the groove and wrapped with adhesive tape, and it can heal after two or three years.

(2) Before plastic surgery, we should check the situation of the tree repeatedly, and look at the straightness of the trunk and the position of the main branches. We should make a plan first, and plastic surgery can be carried out from bottom to top. The vertical planes between layers should not overlap too much, which is conducive to the growth of light transmission, otherwise the blocked part will naturally lose control and die for a long time.

(3) The length of the upper and lower branches is generally long at the bottom and short at the top. From the front of appreciation, the front branches are short and the back branches are long, and the trunk and main branches should be exposed. The proportion of main branches at the bottom of the trunk should be coordinated.

(4) In the cultivation of main branches, the use of scattered branches can make the proportion of dry branches change harmoniously, reduce messy twigs and leaves, thus overcoming the shortcomings of rough leaves and improving the ornamental value of pine and cypress.
