不同施肥处理对臭辣树容器苗生长和苗木质量的影响研究

The Effect of Different Fertilization Management on Growth and Seedling Quality of Evodia fargesii Container Seedlings

不同施肥量对臭辣树容器苗生长和苗木质量的影响的结果表明,6月中旬到8月中旬为苗高速生期,地径在整个试验期内都存在明显的增长。施肥1.0 g处理时苗高最大、根径比最低,与0.5、2.0 g处理间存在显著差异;施肥1.5 g处理时地径最大、高径比最低、质量指数最大,但与施肥1.0、2.0 g无差异;1.0、1.5、2.0 g处理的主根长、生物量及分配无显著差异。因此,在生产中应选择每株施缓效肥1.0 g培育1年生臭辣树容器苗,苗高可达47.1 cm,地径可达5.29 mm,主根长12.41 cm,总生物量4.64 g。

In order to study the effect of different fertilization management on growth and seedling quality of Evodia fargesii container seedlings by different quantity of slow-release fertilizer were fertilized. The result showed that the height of seedlings grows fast from mid-Jun to mid-Aug, and ground-diameter of seedlings grows obvious in whole test period. When fertilizing 1.0 gram slow-release fertilizer per seedling, the height of seedlings was the largest, and the ratio of height to ground-diameter was the lowest, and both have distinct difference with above-mentioned index of fertilizing 0.5 and 2. 0 gram per seedling. When fertilizing 1.5 gram per seedling ground-diameter is lowest, the seedling quality i mentioned index of fertilizing 1.0 and 2.0 gram of main root and biomass of fertilizing 1.0, , the ground-diameter is best, the ratio of root to s biggest, and all have no distinct difference with above- per seedling. There were on distinct difference in length 1.5 and 2. 0 per seedling. Synthesizing the above morphological indexes and production cost, 1.0 gram slow-release fertilizer per seedling should be choice, the height of one year seedlings was 47. 1 centimeter, the ground-diameter was 5.29 millimeter, the length of main root was 12. 41 centimeter, and total biomass was 4. 64 gram.
