目的
2
探究适宜林下参生长的林型及土壤环境。
方法
2
以9年生林下参为研究对象,选取6种常见栽培林型,对林下参产量、质量、土壤化学性质、土壤酶活及土壤微生物代谢等指标进行分析。
结果
2
不同林型下人参质量差异显著,蒙古栎林质量最优,皂苷总质量分数达到2.27%,较最次落叶松林高出51.89%;产量落叶松林与蒙古栎林较高,比最低的白桦林高出62.5%,达到了30 g·m
-2
。蒙古栎林的有机质、Cu、Zn均低于其余林型,蔗糖酶、脲酶相较于其余林型也较低,土壤微生物对
D
-半乳糖醛酸的利用高于其他林型,对
L
-苯基丙氨酸的利用低于其余林型,白桦林土壤微生物对2-羟苯甲酸利用呈度低于其余林型。相关性分析结果显示,土壤Zn与人参皂苷Rb
1
与Rc具有负相关,K与人参皂苷Rb
2
、Rb
3
呈负相关,Mn和Cu与大部分皂苷含量呈正相关。冗余分析结果表明,利用氨基酸类、酯类、酸类、糖类碳源的土壤微生物是造成不同林型间林下参差异的主要因素。
结论
2
蒙古栎林下人参产量及质量均为最优,杂木林次之,而白桦林对林下参生长较为不利,该研究为林下参产量质量的提高及生态种植技术的完善提供理论支撑。
Objective
2
To explore the forest type and soil environment suitable for
Panax ginseng
.
Method
2
The yield, quality, soil chemical properties, soil enzyme activity, and soil microbial metabolism of 9-year-old
P. ginseng
under different forests were investigated.
Result
2
The quality of
P. ginseng
was significantly different among forest types. To be specific,
P. ginseng
under the
Quercus mongolica
forest had the highest quality, with the total saponin content of 2.27% which was 51.89% higher than that in
P. ginseng
under
Larix gmelinii
forest. The yield of
P. ginseng
under
Q. mongolica
forest and
L. gmelinii
forest (30 g·m
-2
) was the highest, 62.5% higher than that under
Betula platyphylla
forest. The soil content of organic matter, Cu, and Zn, and activity of sucrase and urease under
Q. mongolica
forest were lower than those under other forest types. The utilization rate of
D
-galacturonic acid by soil microorganisms under
Q. mongolica
forest was higher than that under other forest types, but the utilization rate of
L
-phenylalanine was lower than that under other forest types. The utilization rate of 2-hydroxybenzoic acid by soil microorganisms of
B. platyphylla
forest was significantly lower than that under other forest types. There was a negative correlation between soil Zn and ginsenoside Rb
1
and Rc, and between soil K and ginsenoside Rb
2
and Rb
3
. Mn and Cu were positively correlated with most saponins. The results of redundancy analysis showed that the soil microorganisms using carbon sources of amino acids, esters, acids, and sugars were the main factors causing the differences in
P. ginseng
among different forest types.
Conclusion
2
The yield and quality of
P. ginseng
under
Q. mongolica
forest were the best, followed by the forest with different tree species, and coming in last was the
B. platyphylla
forest
.
This study is expected to provide theoretical support for the improvement of
P. ginseng
yield and quality and the improvement of ecological planting technology.
