施肥对格木苗木生长的影响试验

Effect of Fertilization Treatments on Seedling Growth of Erythrophleum fordii

在普洱市林业科学研究所育苗大棚内采用L9（33）正交试验,用圈肥（腐熟羊粪）、复合肥和微生物肥（阿维菌素）进行3因素3水平对3个月龄格木播种苗生长影响试验。结果表明：随着圈肥和复合肥施肥量的增加,格木苗高生长呈递增趋势,处理9对格木苗高的生长效应影响最显著,是处理1的2.03倍;影响格木地径生长最显著的是处理7,是处理1的1.59倍。综合不同施肥处理对苗高和地径生长的影响,处理7是格木幼苗培育过程中适宜的施肥方式。

Applying L9（ 33） orthogonal experiment,the effects of three factors and three level of sheep manure,compound fertilizer and microbial fertilizer（ amentia） on three months old seedling growth of Erythrophleum fordii in the cultivation house of Puer City Forestry Science Institute have been conducted.The results showed that with the increasing of organic fertilizer and compound fertilizer,seedling height growth presented increasing trend. Treatment 9 had the most significant influence on seedling height,which was 2. 03 times higher than that of treatment 1. The effect of treatment 7 on diameter growth was the most significant,which was 1. 59 times of treatment 1. To sum up that treatment 7 was the suitable fertilization in the process of cultivating Erythrophleum fordii on seedling height and diameter growth in different fertilizations.
