In order to solve the lack of seedlings of Korean pine and promote the rapid development of Korean pine plantation, I was in the spring of 1975 in the grassland estuary Xigou production team, the choice of the southeast slope, a gradient of 18 °, the 13-year-old Korean pine seedlings transplanting Afforestation experiment, a total of more than a thousand transplants. According to the survey conducted in August 1978, the preservation rate was 85%, the average tree height was 3.33 meters and the diameter was 3.9 centimeters.
