Abstract:A contrast test was carried out using the orthogonal test method on effects of seedling emergence of Chinese fir seed. Different application level of calcium super phosphate, rapeseed cake powder and compound chemical fertilizer was applicated into test field during the test period. The results showed that all treatment combination of the mixed application with calcium superphosphate and compound chemical fertilizer can promote seedling emergence of Chinese fir seed. The optimal combination is the mixed application with 750 kg per hm 2 calcium superphosphate and 375 kg per hm 2 compound chemical fertilizer. The emergence rate is 30.3% higher than the control's.
