Abstract

Using the background materials of Chinese fir seed orchard at 1. 5 offspring in Hengfan Forest Farm, an observation was made on the dynamic of individual cone bearing number, the relationship between the colonial structure and the seed yield, cone economic traits and effect of ecological factors. The seed yield in the orchard was chiefly affected by planting density, cone number of each plant , cone weight and seed-extracting percentage. An experimental formula on seed yield was suggested. In 1995, the 10-year seed orchard obtained a seed yield of 243 kg hm- 2. A reasonable colonial structure of bumper harvest was established in existing density of 525 plants hm- 2, crown sensity of 0. 6, averag eset ting numbers of 661. 9 per plant and seed-extracting percentage of 6. 2%.
