本交通过对平坝华山松种子园土壤肥力、针叶养分状况与华山松无性系开花结实相关性的研究．寻找出种子产量低的原因．结果表明低产的原因之一是营养生长差．表现在该园土壤缺P少K，缺B．针叶养分状况反映出B的缺乏．同时N、P、K也偏低．故而施肥是解决的措施之一．施P提高雄花量，是对照的13．5倍，施B提高雌花量和座果量，为对照的1．2倍、2倍。
Study on Correlation between Soil Fertility, Coniferous Nutrient Status and Flowering and Fruiting of Pinus armandi Clone in Pingba Huashan Pine Seed orchard. Find the reason for the low seed yield. The results showed that one of the reasons for low yield is poor vegetative growth. The lack of soil performance in the park P less K, missing B. Needle leaf nutrient status reflects the lack of B. At the same time N, P, K is also low. Therefore fertilization is one of the measures to be taken. Shi P increase male flowers, 13.5 times the control, Shi B to increase female flowers and fruit volume, 1.2 times the control, 2 times.
