Acer elegantulum grows fast and is convenient for seed propagation. In this study, we used 2-3 years old Acer elegantulum as the basal plant material to make diverse shapes of vase, stylet and hedge. Later, some high ornamental value maples, including Acer palmatum cv. Dissectum, Nagareizumi and red maple were grafted into the vase, stylet and hedge to make higher ornamental value products. This technology strongly improved the economic value of maples. Plant model use the plant as raw material, with design by means of the group modeling, created with the characteristics of the plant and for environmental requirements, melting gardening, aesthetics, sculpture etc. as one of the artistic image form [1]. The Acer elegantulum is commonly known as a specie of Qingfeng, and is often used as the grafting root stock of Acer palmatum cv. Dissectum and red maple. Because of its less ornamental value when compared with Acer palmatum and its ornamental varieties, the market price of Acer elegantulum is low. Then using Acer palmatum as plant materials, employing of vase, screens and other art forms, grafting the ornamental species of the feather maple, red maple, Nagareizumi, Acer palmatum aureum and other horticultural varieties, producing different patterns of plant modeling work, is an effective technique to improve the ornamental value and economic benefit of the Acer elegantulum. The Breeding of Acer Elegantulum Seedlings Standard of Acer Elegantulum for Moulding. The Acer elegantulum which is used to modeled is different from the one that used as rootstock. According to the vase's shape, nursery stock specifications should follow three basic requirements: trunk is straight; taper is small, relatively uniform thickness; with a certain height, generally more than 2m. Growth of Acer elegantulum seedlings for moulding Seeds sawing and breeding Collecting the fruit when the Acer elegantulum's fruits change from red to brown in the late October to November. After drying the fruit, remove the fruit wings, fruit stalk and impurities and empty seeds by gently rubbing. Placed the mature seeds in ventilated shade or stored in the clean Kawasa Sadumihide before the next growing season. Use the plastic greenhouse as the nursery to plant seeds, and sowing the seeds in next year from January to February. Then transfer the seedlings to the outdoor in late February to March. Strewing and drilling is available for seeds sowing, and the sowing rate is about 12 ~ 15g / m-2. After sowing, covering 1 cm fine soil to cover the seeds, and it should be covered with 2 ~ 3 cm straw before sprinkle profoundly water. After these steps, providing enough water for their growth. The control of seedling density About 20-25d after the cotyledon emerging, we should regularly check the growth situation of Acer elegantulum and remove the straw. Modeling Acer elegantulum seedlings' cultivation should maintain a higher planting density to get the slender seedlings. In the strewing and drilling ground where the seedling density is too low can be filled throu...
