Effect of a Compound Microbial Fertilizer on Growth, Quality, and Soil Properties of Andrographis paniculata
To study the effect of a microbial compound fertilizer on the growth, quality, and soil properties of
Andrographis paniculata
and provide a basis for its application in the cultivation and production of
A. paniculata
.
Method
2
Through five treatment tests in pots, the control group (CK, no fertilization), the treatment A group (chemical fertilization), the treatment B group (microbial fertilization at 2.5 g·kg
-1
soil), the treatment C group (microbial fertilization at 7.5 g·kg
-1
soil), and the treatment D group (microbial fertilization at 12.5 g·kg
-1
soil) were established. The effects of a compound microbial fertilizer on the agronomic properties, the content of active ingredients, the number of rhizosphere soil bacteria,
Actinomycetes
, and fungi, and soil physicochemical properties of
A. paniculata
were studied.
Result
2
As compared with the CK group and the treatment A group, the plant height, leaf number, leaf area, and above-ground and below-ground fresh weight of
A. paniculata
were significantly increased after microbial fertilization, with differences in different growth periods. The effect of the compound microbial fertilizer on the content of andrographolide, dehydrated andrographolide, neandrographolide, and 14-deoxyandrographolide differed. The content of andrographolide significantly increased by 26.13% and 13.23% in the treatment C group, respectively, as compared with the CK group and the treatment A group (
P
<
0.05). The content of neandrographolide increased with the increasing amount of microbial fertilizer, and the content in the treatment D group increased by 9.06% and 50.33%, respectively, as compared with the CK group and the treatment A group (
P
<
0.05), which was the most obvious. The content of 14-deoxyandrographolide in the treatment B group significantly increased by 42.04% and 1.74%, respectively, as compared with the treatment A group and the CK group (
P
<
0.05). The content of dehydrated andrographolide content in the treatment B group increased most significantly, significantly increasing by 11.73% and 27.74%, respectively, as compared with the CK group and the treatment A group (
P
<
0.05). The soil pH of the treatment B, C, and D groups was higher than that of the CK group and the treatment A group. The content of total nitrogen and effective phosphorus increased most significantly in the treatment B group, and the content of fast-acting potassium increased most significantly in the treatment D group. The application of the compound microbial fertilizer increased the number of rhizosphere soil bacteria and
Actinomycetes
, which was significantly higher than that in the CK group and the treatment A group (
P
<
0.05), and increased with the increase of applied amount. The number of fungi decreased with the increase of the compound microbial fertilizer application, which was significantly different from that in the CK group (
P
<
0.05). The fungi/bacteria of all treatment groups were significantly lower than those of the CK group (
P
<
0.05) and increased with the increase of microbial fertilizer application.
Conclusion
2
The application of the compound microbial fertilizer transforms the plant-soil-microbial system in a benign direction, which is beneficial to the growth of
