Abstract: The paper aims to study an efficient cultivation techniques of geometric sculpt and enrich product type for Ulmus pumila ‘Zhonghua Jinye’, experimental research for the cultivation techniques on geometric sculpt were carried out by using different sculpt techniques. The results showed that the first clip was typically carried out on two months after grafting for simple geometry sculpt (about 15cm-20cm in length). Next year, 1/3 crown was pruned before buds on the trees. The branch was clipped for each growth 20cm in length, then, little by little , it cut into geometric shape which would take two years to achieve. The efficient breeding technical of composite texturing use existing product and group it directly, volume-produce was realized in the same year and shorten rearing period, and meanwhile the value of the products could be enhanced.
