Effect of Different Treatments of Fertilizers on the Growth Increments of Taxus yunanensis Seedlings
摘要
Abstract
[Objective] The purpose to research the effect of 16 kinds of base fertilizers and 1 control treatment on the growth of Taxus yunnanensis. [ Method ] The T. yunnanensis seedlings were bred by two-stage breeding method and the effect of different treatments on their growth increments was researched by single-factor randomized block design. [ Result ] The average tree height of T. yunnanensis of a1l the treatments was 125. 1 cm and its changing range was 109. 1 -52.9 cm; their average ground diameter was 2.63 cm and its changing range was 2.29 - 3.02 cm. The average dry weight of aerial part of T. yunnanensis seedlings in the 17 treatments was 225.4 g and its changing range was 122. 0 -389. 0 g; their average dry weight of underground part was 108.4 g and its changing range was 84. 1 - 128. 0 g; their average dry weight of whole plant was 333.8g andits changing range was 206. 1 - 517. 0 g. Compared with CK, the tree height, ground diameter, dry weights of aerial part, underground part and whole plant of T. yunnanensis seedlings in the treatment of 4.8 kg ox dung + 3. 0 kg serrago per plant were increased by 40％, 32％, 219％, 52％ and 151％ resp. [ Conclusion] The comprehensive appearance of T. yunnanensis seedlings in the treatment of 4.8 kg ox dung + 3. 0 kg serrago per plant in their growth period was best.关键词
