【Abstract】 The experiment shows that yield and quality of trunk section area 0.3 kg/cm 2 is the best under average management on Loess Plateau. Fuji apple single weight is 195 g(34 t/hm 2), and contents of N, P and K are moderate in trees, and the color is well, so these are regarded as best yield. When the yield lowers or exceeds trunk section area 0.3 kg/cm 2,its yield reduces and its resistance drops at the same time.更多还原
