2023, 42(1): 1-10.   doi: 10.12390/jbr2022080
Abstract(80) PDF(104)
【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(33) PDF(12)
【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.

The tensile force and displacement curve of the mortise joint structure showed four development stages: straight-line rise, slow curve rise, straight-line rise and straight-line decline. 【Conclusion】The design of detachable mortise joint structure has the characteristics of simple processing technology, green environmental protection, health and safety, and its tenon can realize mass, standardized production. This study has important guiding significance for the rationality of bamboo furniture structure design, and is conducive to the innovative development of bamboo furniture.

对竹材饱和蒸汽炭化热处理工艺参数进行了优化研究,分析其对竹材加工废水和竹材颜色的影响,试验结果表明,竹材热处理时间和饱和蒸气压对其废水排放量和COD值均呈正相关,即饱和蒸气压越高、处理时间越长,则废水排放量越多、COD值越高;且当饱和蒸汽压超过4.2 MPa·s时(对应热处理温度为250℃左右),竹材加工废水COD值跃增。通过色差L*、b*、ΔE*值与蒸煮饱和蒸气压和炭化时间的线性关系,建立竹材色差与热处理工艺的相关性数学模型,根据现有竹材产品颜色预估热处理工艺。具此分别对浅色系、中深色系、深色系加工竹材进行工艺优化,相比与传统工艺,优化竹材热处理工艺分别降低单位质量废水排放量11.53%、11.32%、12.5%,总有机物排放量分别降低51.91%、43.03%、28.56%,具有较好的实际生产指导意义。

Xuyong county is rich in Pleioblastus amarus resources, covering an area of more than 40,000 mu. Pleioblastus amarus forests are mainly distributed in Longfeng, Xuyong, Tianchi, Shuiwei, and Lianghe town, their management is extensive, most of them are in a state of desolation, and the economic benefits are very poor. In order to improve the economic benefits of Pleioblastus amarus forests, poverty alleviation and cooperation experts from Zhejiang and Sichuan province carried out an early-shooting and high-yield cultivation technology experiment in Pleioblastus amarus forests in 2019. The experimental forest with an area of 13.6 Mu was established by replacing conventional covering materials with waste bamboo chips. The results showed that the surface soil temperature was obviously increased by the covering waste bamboo chips. The bamboo shoots appeared 77 days earlier than normal control and the shooting period was extended to 82 days. The yield was 24 t·hm-1 and the benefit was 260 thousand Yuan·hm-2. The covering cost was greatly reduced and the economic benefit was improved. The post-coverage waste bamboo chips can be reused as culture medium material of edible fungi under the forests to realize the secondary utilization. A set of early-shooting and high-yield cultivation technology of Pleioblastus amarus was proposed, this may provide a demonstration for farmers to increase their income and overcome poverty in Sichuan Province.
