摘要:
以二月生格木为试材，采用完全随机处理方式，设置5种不同浓度的铝和2种不同浓度的硝普钠互作处理，通过测定苗高、地径、叶面积、生物量和根系指标，比较不同浓度的铝和硝普钠互作对格木生长的影响，以期为格木的育苗及生产提供科学依据。结果表明：各处理组的格木幼苗株高增长量、地径增长量、叶面积增长量及生物量总体呈先上升后下降的变化趋势，且均在T6（0.4 mmol?L-1 AlCl3、0.1 mmol?L-1 SNP）处理下最高，而在T9（0.8 mmol?L-1 AlCl3、0 mmol?L-1 SNP）处理下最低，各处理组均差异显著；总根长、根尖数、总根体积、总根表面积和根平均直径均呈先上升后下降的变化趋势，各处理组均差异显著；综合评价中T6最佳，T5次之。综上所述，不同浓度的铝（AlCl3）和硝普钠（SNP）处理下格木生长指标差异显著，且均在T6（0.4 mmol?L-1 AlCl3、0.1 mmol?L-1 SNP）长势最好。
Abstract:
A completely random design was used for studying the effects on the growth of  Erythrophleum fordii by five different concentrations of AlCl3 and two different concentrations of SNP interaction.In order to provide scientific basis for growing seedlings and production by measuring plant height,ground diameter,leaf area,biomass and root indexs.The increment of plant height,ground diameter and leaf area and biomass were firstly increased and then decreased in general.The results showed that the increment of plant height,ground diameter and leaf area and biomass reached the maximum under T6（0.4 mmol?L-1 AlCl3,0.1 mmol?L-1 SNP） but dropped to the lowest under T9（0.8 mmol?L-1 AlCl3,0 mmol?L-1 SNP）.The treatments were significantly different.The trend of variation root indexs were firstly increased and then decreased.The treatments was still pretty different.The comprehensive evaluation of T6 was the best combination and then T5.In a word，the interaction of different concentration of AlCl3 and different concentration of SNP carry significantly different for growth indexs of Erythrophleum fordii.The T6 (0.4 mmol?L-1 AlCl3，0.1 mmol?L-1 SNP) was the best combination.
