萌芽水曲柳与人工红松形成的混交林综合效果显著,混交林不但促进水曲柳生长,而且对红松无不利影响。混交林与红松、水曲柳纯林相比:蓄积量分别提高20.3％,73.2％;生物量提高30.5％,39.3％;经济效果提高21.8％,50.7％;无论与单层纯林,还是多层混交林相比,都是较稳定的群落,而且,林分的高生长,材积生长处于上升阶段,土壤理化性质不断得到改善,为混交林长期稳定高产奠定了坚实的物质基础。
Mixed forest formed by sprouting manchurian korean pine and artificial korean pine had significant effects. Mixed forest not only promoted the growth of ash, but also had no adverse effect on korean pine. Compared with pure Korean pine and Pinus koraiensis plantations, the stock volume increased by 20.3% and 73.2% respectively, the biomass increased by 30.5% and 39.3%, the economic effect increased by 21.8% and 50.7%, respectively. Compared with the mixed forest, it is a relatively stable community. Moreover, the high growth and volume growth of the stands are in the ascendant stage, and the physical and chemical properties of the soil are continuously improved, laying a solid material foundation for long-term, stable and high-yield mixed forest.
