Research results: The manually auxiliary maintenance should be done to the transplanted turf, which is helpful for the turf's growth. The basically same outcome can be obtained as that from integrally transplant by transplanting the 15cm upper part of turf. The 15cm-17cm interval between turfs is the most favourable for the turf's growth, because turf has a perfect growing capacity. The research outcome has been applied in the environment recover project for Qinghai-Tibet Railway, which has brought about remarkable social and economic benefits.
