With the growing cultivation area, the production of early results, the early bumper crop cultivation techniques are increasingly important. In order to provide the theoretical basis for formulating the correct production technology and management measures, we observed the differentiation rules of flower buds of pear and pear in Lanzhou from 1980 to 1981. Now the preliminary results briefed as follows. Materials and Methods The experiment was conducted in our hospital Lanzhou farm orchard for two consecutive years from 1980 to 1981.
