摘要
为探究不同施肥方式对八角苗木生长的影响,设计6种施肥处理(含对照),分析氮(N)、磷(P)、钾(K)配比对苗木生长指标、生物量积累及苗木质量的影响。结果表明,不同施肥方案显著影响八角苗木地下部分生物量及叶片光合能力,其中处理T3(尿素2 g/株、过磷酸钙3.0 g/株、氯化钾1.8 g/株)地下鲜质量和干质量分别较对照提高55.33%和43.12%,叶片SPAD值达47.99,显著高于其他处理(P<0.05);综合苗木质量指数,T3处理为最优施肥方案。本研究可为失管八角苗木复壮及精准施肥提供理论依据。
To explore the effects of different fertilization methods on the growth of Illicium verum seedlings,six fertilization treatments(including controls)were designed,and the effects of the ratio of nitrogen(N),phosphorus(P),and potassium(K)on the growth indicators,biomass accumulation,and seedling quality of the seedlings were analyzed.The results showed that fertilization significantly affected the biomass of the underground part and the photosynthetic capacity of leaves of Illicium verum seedlings.Considering the comprehensive quality index of seedlings,T3 treatment was the optimal fertilization scheme.This study could provide a theoretical basis for the rejuvenation and precise fertilization of unmanaged Illicium verum seedlings.
