Experimental studies on wrapped seeds of afforestation by aerial seeding

Through 90 kinds of treatment,the 92-03 formulation was screened towrap seeds.Planting Percent of wrapped seeds on mountain was 27.3%~37.5% higherthan control and seedling's height of wrapped seeds was 16.7%~27.7% higher than con-trol after middle and productive experiments in large area. seeds demand per mu can be 50g lower than before for afforestation by aerial seeding with Pinus massoniana Lamb.Itwill save RMB 628,000 yuan to afforest 66667 hm² by aerial seedling.
