Abstract:
【Objective】 In order to unveil the functional differences of leaves of Phyllostachys edulis and its two variants,Ph. edulis 'Pachyloen’ and Ph. edulis 'Bicanna’,and their relationships with the morphological characteristics of bamboo culms.【Method】 The study employed paraffin sectioning and microscopy techniques to investigate the morphological and anatomical features of leaves,thereby three-dimensional morphological structure diagram of the leaves were created and the physiological indexes were determined through anthrone colorimetry. The study also observed variations in culm shape factors among different bamboo species,followed by a detailed examination of the correlation between leaf structure and culm shape characteristics. 【Result】 The results of this study suggest that Ph. edulis has greater leaf area bulliform cell area,and vascular bundle area,along with thicker leaves,lower epidermis and mesophyll. These specific leaf structural characteristics of Ph. edulis exceed those observed in the other two bamboo species,which is more conductive to photosynthesis. The leaf structure and culm morphology of Ph. Edulis,and its variant type,Ph. edulis 'Pachyloen’,have a strong correlation. 【Conclusion】 The structural characteristics of Ph. edulis leaves are more conducive to photosynthesis and promote the accumulation of vital substances for the growth of bamboo culms. Both Ph. edulis and its variant,Ph. edulis 'Pachyloen’,can balance resource allocation by modifying the traits of leaf and culm so as to ensure consistent growth. This study establishes a foundation for further unveiling growth and development mechanism of bamboo,providing a scientific basis for generating novel bamboo germplasm.

Abstract(96) PDF(20)
Abstract:
【Objective】 To investigate the effects of different fermentation methods on the main nutrients and functional content of pickled and dried mustard,and to provide a certain theoretical basis for improving the production process of pickled and dried mustard. 【Method】 Two fermentation methods,i.e. mixed fermentation of bamboo shoots and mustard and separate fermentation of mustard,were used to produce pickled and dried mustard,and then the nutrients such as proteins,soluble sugars and dietary fibers as well as minerals and functional substances of the two types of pickled and dried mustard and fresh mustard were measured and analyzed. 【Result】 The results showed that the content of mineral elements such as calcium,iron,magnesium and potassium of the mixed fermented pickled and dried mustard was significantly lower than that of the individually fermented pickled and dried mustard,in which the content of iron and magnesium was significantly lower than that of fresh mustard at the same time,and only the content of phosphorus was significantly higher than that of the individually fermented pickled and dried mustard and fresh mustard,indicating that the effect of mixed fermentation on the content of mineral elements of pickled and dried mustard was smaller than that of individually fermented. Compared with fresh mustard,there was a significant increase in dietary fiber and protein content and a small decrease in soluble sugar content in the mixed fermented pickled and dried mustard,whereas there was a significant decrease in nutrient content of soluble sugar,dietary fiber and protein in the individually fermented pickled and dried mustard. In addition,differences in fermentation methods significantly affected the changes in functional substance content,where mixed fermentation significantly enhanced the content of antioxidant functional substances such as vitamin E,β-carotene and vitamin C in pickled and dried mustard. 【Conclusion】 Overall,differences in fermentation methods significantly affected the content of mineral elements,major nutrients and functional substances of pickled and dried mustard. Comparatively,the mixed fermentation method has a better ability to increase the nutrients and antioxidant substances content of pickled and dried mustard.

Abstract(134) PDF(150)
Abstract:
The manufacturing processes involved in plastic button production,including the processing,molding,and post-processing of raw materials,cause certain pollution to the environment. The popularization of green environmental protection concepts and the evolution in the apparel and fashion industry have led to new demands for innovation and transformation in the button-making industry. The Chinese government,in collaboration with the International Bamboo and Rattan Organization,launched the Bamboo as a Substitute for Plastic Initiative in November 2022,aiming at reducing plastic pollution and addressing climate changes. Bamboo buttons,an archetypal product of this drive,offer advantages in terms of resources,industry,markets,and environmental protection while also serve as a tangible representation of the traditional Chinese culture,such as bamboo and clothing. This paper provided an overview of button types,market status,and the industrial advantages and economic analysis of bamboo buttons as alternatives to plastic buttons. The processing techniques,fundamental properties,and key technological challenges in bamboo button production were discussed. Moreover,the paper addressed the deficiencies in the current bamboo button industry by proposing recommendations and prospects for strengthening policy support,promoting technological transformation,innovating processing technologies,and facilitating the integration of traditional culture and exploration of consumer markets. The objective of this review is to fulfill goals of carbon peaking and carbon neutrality,implement the Bamboo as a Substitute for Plastic Initiative,and provide new approaches for developing a human community with a shared future as well as China’s green and modernized industries.

2024, 43(1): 28-35.   doi: 10.12390/jbr2023055
Abstract(41) PDF(9)
Abstract:
【Objective】 To systematically study the changes of physical and chemical properties of bamboo-based hydrothermal charcoal at different hydrothermal temperatures. 【Method】 In this paper,bamboo-based hydrothermal charcoal was prepared from Dendrocalamus farinosus at a series of hydrothermal temperatures (453,493,513,533 and 573 K),the physicochemical properties of hydrothermal charcoal such as element content,pore structure and surface functional groups were characterized,and the adsorption performance of uranium (U6+) was evaluated. 【Result】 The results showed that:the cultivated D. farinosus was rich in cellulose and hemicellulose,which could be preferentially converted into carbon micro-spheres at lower temperatures,this was conducive to forming the developed pore structures. The hydrothermal charcoal prepared in the low temperature zone contained both high yield and rich functional groups (453 and 493 K),and the bamboo-based hydrothermal charcoal prepared at 493 K temperature had the largest specific surface area (55.61 m2·g-1) and the smallest average pore size (7.77 nm),with the characteristics of high-quality adsorption structure. While the high temperature zone (513,533 and 573 K) had destroyed the high-quality adsorption structure and functional groups. The U6+ adsorption test results further confirmed that the bamboo-based hydrothermal charcoal prepared at 493 K was the best for U6+ adsorption,and the adsorption capacity reached 12.63 mg·g-1. 【Conclusion】 The U6+ adsorption efficiency of hydrothermal charcoal from D. farinosus under the condition of 493 K is higher,and it has more advantages in resource utilization and nuclear pollution control.

【Objective】 In the context of continuously increased labor costs,the bamboo industry in China takes on differentiated developmental trends,impacting its income-increasing effects,highlighting an urgent need for attention. 【Method】 This paper traces the development history of China’s bamboo industry to grasp its current status. The focus then shifts to the provincial scale,comparatively analyzing the development characteristics and influencing factors of the bamboo industry in Zhejiang and Sichuan provinces. 【Result】 Comparative analysis indicates that:(1) Regarding the factors of natural resources,due to differences in bamboo species resources,the two provinces have adopted distinct industrial orientations. Zhejiang is directed towards a comprehensive bamboo industry chain,while Sichuan emphasizes bamboo pulping and papermaking as its pillar industries. (2) In the aspects of labor force and industry resources,Zhejiang prefers attracting high-skilled labor,having obtained significant added value,and its industry agglomeration effect is pronounced. In contrast,Sichuan,though its labor costs are lower,leans heavily on low-skilled labor force. (3) At the policy level,Zhejiang prioritizes technological innovation,in-depth product processing,and environmental sustainability. Sichuan,however,leans more on resources utilization and the development of the papermaking sector,with a higher tolerance of pollution-intensive industries. 【Conclusion】 In light of the above results,it’s imperative to innovate developmental models with an emphasis on processing. Furthermore,there’s a need to bolster the growth of small and micro-enterprises,advocating green technological advancements,and finally needing to intensify collaboration with research institutions to address environmental issues.

Abstract:
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.
