油松种子林生长结实影响因素研究

Research of Influencing Factors of Fructification of Pinus Tabulaeformis Seed Forest

该文对去劣疏伐、整形修剪以及土壤耕作施肥对油松种子林生长结实的影响进行了探讨。结果表明:与对照相比,处理组对油松种子林生长和结实的促进效果都比较显著,结实量分别是对照组的2.74倍、3.41倍和3.40倍。经过去劣疏伐、科学的修剪和土壤耕作施肥,光照和营养条件有所增加,为油松的生长结实提供了良好的物质基础和环境条件,起到了很好的促进作用。

In this paper, roguing, pruning and tillage fertilization were conducted using the contrast test. Results showed that compared with the controls, treatment groups have a significant promotion effect on the growth and fructification of Pinus tabulaeformis seed forest. Cone productions were respectively 2.74 times, 3.41 times and 3.40 times higher than the control group. Through roguing and scientific pruning and tillage fertilization, the light and nutrients conditions were improved and a good material basis and environmental conditions were provided, which had played a good role in promoting the growth and cone productions of Pinus tabulaeformis.
