Abstract: The study aims to find suitable culture technique mode for dwarf rootstock orchard for SH series apple in Shanxi. Considering the characteristics of dwarf rootstock for SH series of apple, the study used intensive and highly- efficient culture technique mode of M26 apple dwarf rootstock and water- saving irrigation method of standard rootstock orchard as the reference, investigated and determined the tree irrigation amount, the branch quantities and composition of branches, the growth of tree leaf, the chlorophyll content of tree leaf, the fruit quality in apple orchard with dwarf rootstock under 4 methods, including broad irrigation, furrow irrigation under covered ridge with ridge forming, biological matrix cover and grass cover under tree. The result showed that after‘Hongfushi’apple orchard with dwarf rootstock was irrigated by furrow irrigation under covered ridge with ridge forming, the cost could be cut, structure of tree branches was good and economic benefits and high quality could be obtained. Furthermore, with furrow irrigation under covered ridge with ridge forming, dry weight, thickness, area, chlorophyll content of 100 leaves and output of the orchard were higher than that under other treatments, therefore this mode could be regarded as a more suitable one to climate and site type of Shanxi.
