Where is Amomum villosum grown?

Amomum cultivation in natural forests Since 1963, A. villosum has been successfully cultivated in tropical forests in Southern Yunnan. According to the Statistics Bureau of Yunnan Province (unpublished data, 1989 ), the total planted area is now over 13 000 ha.

What is Amomum villosum?

Amomum villosum is commonly grown in plantations of such trees as Hevea brasiliensis, Cinnamomum porrectum, Mangifera indica, Albizia chinensis, A. falcataria and Cassia siamea, forming a two-layered agroforestry system (Fig. 2). Rubber tree-Amomum, a common underplanting combina- tion, has shown noticeable economic profit.

Do photovoltaic panels affect plant diversity?

There was no effect of photovoltaic panel presence on plant diversity. Flowering time of annuals and growth of sedum were enhanced in plots with a panel. Abundance of some arthropod taxa was lower in plots with a photovoltaic panel. The presence of the green roof did not improve electricity production by the panels.

Do PV panels affect Sedum?

While vegetation abundance was generally not affected by the presence of PV panels, sedum was 80% longer in the area in front of the panel ( Fig. 4 E) and under the panel ( Fig. 4 F) than in the same areas in plots without a panel, in both years ( Table 4 ).

Can Broccoli grow under photovoltaic panels?

Researchers in South Korea have been growing broccoli underneath photovoltaic panels. The panels are positioned 2-3 metres off the ground and sit at an angle of 30 degrees, providing shade and offering crops protection from the weather.

Does PV affect plant growth?

However, the presence of PV did seem to have a positive effect on plant growth and survival later in the season, as indicated by the longer flowering length and larger sedum in the area surrounding the panel.
