Abstract:
【Objective】This paper aims to explore the anatomical characteristics of natural Qiongzhuea tumidinoda rhizome under different soil water and nutrient conditions, and to compare the adaptive strategies of Q. tumidinoda rhizome in different habitats.【Method】The relationship among the anatomical structure characteristics of Q. tumidinoda rhizome, soil nutrient and water in three soil depths (0-40 cm, 0-80 cm and 0-120 cm) was analyzed by using redundancy analysis and Monte Carlo test.【Result】(1) With the increase of soil water and nutrient content, the proportion of fibrous tissue, conducting tissue and vascular bundle density decreased significantly (P<0.05); However, the basic tissue ratio, vascular bundle length, width and aspect ratio of Q. tumidinoda rhizome showed an obvious increasing trend (P<0.05). (2) Among the three soil thickness habitats, the variation coefficient and plasticity index of Q. tumidinoda rhizome including tissue ratio, vascular bundle and fiber size in thin soil layer habitat were the largest. (3) Soil moisture and nutrient factors had significant effects on the anatomical structure of bamboo rhizome (P<0.05). The importance of a single soil factor on the anatomical structure of Q. tumidinoda rhizome was in following order: soil water content > available K > organic matter > total K > available P > total P > hydrolyzed N > total N > pH. The difference of soil moisture and nutrient content was the fundamental reason affecting the anatomical structure plasticity of Q. tumidinoda.【Conclusion】Soil moisture, K and organic matter content had important effects on the formation of bamboo rhizome. Q. tumidinoda can adapt to the restriction of soil factors by regulating the anatomical structure and plasticity of bamboo rhizome. Therefore, in production, the growth and development of bamboo rhizome can be promoted by regulating soil moisture content, addition of K and organic fertilizer.

Abstract:
【Objective】The purpose of this paper is to give full play to the performance advantages of poplar and bamboo exhibition plate. 【Method】In this study, bamboo exhibition plate with different temperature heat treatment (120 ℃, 140 ℃, 160 ℃, 0 MPa for 2 h) was used as surface plate and poplar veneer as core board to make flatten-bamboo-poplar veneer composite board which was made up by assemble patterns of parallel texture. The properties of flatten-bamboo-poplar veneer composite board such as equilibrium moisture content, color difference, gloss, bonding strength, dipping peeling rate, bending strength, modulus of elasticity and so on were tested, and the effects of different temperature treatment of the surface plate on the physical and mechanical properties of the composite board were analyzed. 【Result】The results showed that, in terms of physical properties, with the increase of heat treatment temperature of the surface plate, the equilibrium moisture content of the composite board decreased significantly. The gloss of the composite board decreased gradually, and the color perception stability increased. The total color difference was greater than 1.5, but the color change was not obvious. In terms of gluing properties, the heat treatment of the surface plate reduced the bonding strength of the composite board, reaching the lowest value at 140 ℃. Immersion peeling test showed that the bonding durability of the composite board was first strengthened and then weakened with the increase of temperature. In terms of mechanical properties, the modulus of elasticity and bending strength increased with the increase of heat treatment temperature of the surface plate, and reached the maximum value at 140 ℃. 【Conclusion】The heat treatment of surface plate enriches the visual effect of the flatten-bamboo-poplar veneer composite board, improves the bending strength and modulus of elasticity of the composite board, but has a certain adverse effect on the bonding performance of the composite board. In actual use, it should be selected according to specific needs.

Abstract:
As a relatively unfamiliar traditional calligraphy resource, with the continuous development of archaeology in China, the resources of calligraphy on bamboo slips are constantly being developed and gradually recognized and valued by the calligraphic circle. Since the calligraphy of bamboo slips is the original ink of ancient calligrapher, it is easier for scholars and researchers to capture the most vivid state of writing calligraphy, feel the charm of ink and the characteristics of formal language of the calligrapher, as well as the sense of force generated by the friction between the brush and the writing media and the distinctive charm of the ink that penetrates into the bamboo material. The author privately believes that through the study and practice of bamboo calligraphy, it is easier to approach the nature of calligraphy. Compared with the calligraphy model of tablet inscription after secondary creation, more preserved the original ink appearance and vivid emotional rhythm of calligraphy writing, is second only to the face to face demonstration of the form closest to the writer's real performance and teaching, is an excellent model to learn calligraphy, aesthetic appreciation. It is to establish an effective connection between the reality and this “new” and “unfamiliar” calligraphy “new field”, and to excavate more realistic value of bamboo calligraphy.

Abstract:
【Objective】As the representative of literati, Bai Juyi, a literary magnate of a generation, has applied bamboo landscaping in many gardening activities. His way of bamboo landscaping, experience of bamboo appreciation and bamboo culture outlook have a profound impact on later generations. This paper hopes to further enrich and improve the literati's bamboo culture outlook by analyzing Bai Juyi's residence and poetry. 【Method】This paper analyzes Bai Juyi's multiple residences and the associated poems,and investigates his practice of building gardens with bamboo elements. The poet's inclination to appreciate the bamboo sceneries and his views on bamboo culture are hence revealed. 【Result】It seems evident that most of Bai Juyi's residences featured bamboo landscape. Bamboo windows,bamboo waters and bamboo forests were routinely adopted to build gardens. The poet was fond of observing the bamboo sceneries from various positions and angles,and he underscored the interaction with bamboo when visiting the gardens. These bamboo-related anecdotes and the large quantity of bamboo-themed poems are of great significance for promoting the development of bamboo culture. This paper further exhibits his views on bamboo culture. Bai Juyi was a follower of Confucianism,Taoism and Buddhism,while bamboo,publicly cherished by these three religions,reflects the noble character which is in line with the poet's spiritual pursuit. 【Conclusion】Under the influence of the idea of “gentleman's virtue”, bamboo has become the materialized expression of literati's pursuit of spiritual quality, and bamboo has also become the representative plant of literati's gardens.
