The invention discloses a planting method for white flesh loquats and a greenhouse thereof. The method comprises the following steps: transplanting white flesh loquat seedlings to specified positions at the planting density of (3-5)*(2-4) meters in February to April, preferably March; and fixing poles 25-50 centimeters away from the transplanted white flesh loquat seedlings, keeping four side branches as main branches after side branches sprout each year, keeping three branches sprouting on each main branch for serving as secondary main branches, keeping three branches sprouting on each secondary main branch for serving as a fruiting branch group, and culturing for three and a half years till branches of each tree body reach grade 9-10 so as to enter a blossoming and fruit setting period. Specific to the problems existing in the conventional greenhouse equipment and open field white flesh loquat production, the planting method and the structure of a greenhouse facility are improved, so that yield reducing factors such as freeze injury, fruit cracking, sun burn and the like are eliminated completely, and the aims of preventing freezing in winter as well as shading from rain to prevent fruit cracking and shading from high temperature to prevent sun burn at a fructescence period can be fulfilled.
