Abstract
    This paper introduces very good application possibility of cherry cultivation in protecting conditions. The key techniques for the protective cultivation are using dwarf rootstock of ZY-1,using PP333,setting up high density orchards,controlling the time covering plastics film, temperature,moisture,water content of soil,sun light,gases(CO2、NH3、NO2、SO2、CO、CH2=CH2、Cl2)amount in the greenhouse.So,the high yield,good quality and high effecient of cherry production are able to realize.
