In order to study the marginal effect of Lycopersicon esculentum var. cerasiforme in the greenhouse cultivation, by using the cherry tomato Huangfei inbred line as the material, the main agronomic traits such as the plant height, leaf size, stem diameter, internode length and fruit size were investigated and analyzed. The results showed that the plants planted in the east and middle of the greenhouse were generally higher, and the plant height in the south was higher than that in the north. The plant leaves planted in the east and middle of the greenhouse were generally larger, while the stem diameter of plants planted in the east was larger than that in the west, and similar in the north and south. The plant internodes planted in the west of the greenhouse was longer than those in the east, and the plant internodes in the north and south of the greenhouse were shorter than those in the middle. The fruit was slightly longer overall, but rounder in the middle than at the edges. The results showed that the tomato plants grew better in the east, south and middle areas of the greenhouse, and the marginal effect of cherry tomato in the north and south of the greenhouse was significantly greater than that in the east and west, while the internode length of the plants growing in the west and middle areas was greater than that in the east.

GeTe and (Bi,Sb)2Te3 are two representative thermoelectric (TE) materials showing maximum performance at middle and low temperature, respectively. In order to achieve higher performance over the whole temperature range, their segmented one‐leg TE modules are designed and fabricated by one‐step spark plasma sintering (SPS). To search for contact and connect layers, the diffusion behavior of Fe, Ni, Cu, and Ti metal layers in GeTe is studied systematically. The results show that Ti with a similar linear expansivity (10.80 × 10−6 K−1) to GeTe, has low contact resistance (3 µΩ cm2) and thin diffusion layer (0.4 µm), and thus is an effective metallization layer for GeTe. The geometric structure of the GeTe/(Bi,Sb)2Te3 segmented one‐leg TE module and the ratio of GeTe to (Bi,Sb)2Te3 are determined by finite element simulation method. When the GeTe height ratio is 0.66, its theoretical maximum conversion efficiency (ηmax) can reach 15.9% without considering the thermal radiation and thermal/electrical contact resistance. The fabricated GeTe/(Bi,Sb)2Te3 segmented one‐leg TE module showed a ηmax up to 9.5% with a power density ≈ 7.45 mW mm−2, which are relatively high but lower than theoretical predictions, indicating that developing segmented TE modules is an effective approach to enhance TE conversion efficiency.
