MICROCLIMATE OF SUBTROPICAL CITRUS FREEZEINJURY AREA AND ITS USE FOR CULTIVATION
我国亚热带柑桔冻害区的小气候及栽培利用

icrotherm and freeze injury are the main factors limiting the development of citrus. China is a country with vast expanse of subtropical zones and complicated terrains. Affected by the coexistence of complicated terrain, waterbodies and microclimat as well as by artificial cultivation, threats to economic cultivation of citrus controlled by the occurence frequency of various levels of microtherms might be reduced on tile whole as a consequence of the relative warm winter and relative high minimum temperature existed spatially to a certain degree. Therefore, tile distribution extent fitted for subtropical citrus cultivation got expanded.
