Abstract

This study evaluates six bamboo species, i.e., Dendrocalamus hamiltonii, Bambusa nutans, Dendrocalamus asper, Bambusa bambos, Bambusa balcooa, and Dendrocalamus strictus, regarding their growth behavior, nutrient uptake, and effect on the soil properties of the Terai region. Various aboveground growth parameters exhibited significant variations with the maximum clump girth (8.60 m) and internodal length (35.37 cm) of B. nutans, which was also reported by the culm diameter (5.70 cm) of D. hamiltonii and the number of culms per clump (65) of D. strictus. The total aboveground biomass ranged from 51.14 Mg.ha-1 in D. asper to 362.56 Mg.ha-1 in D. hamiltonii. The most significant variation in soil properties was observed in the 0-40 cm soil layer. Under D. hamiltonii, the lowest soil bulk density (1.07 g.cm3; 1.21 g.cm3) and the maximum soil porosity (59.00%; 56.40%), soil organic carbon (1.54%; 0.72%), and available soil nitrogen (228.29 kg.ha-1; 173.73 kg.ha-1) were found the 0-40 and 40-80 cm soil layers. Furthermore, significant enhancements in soil microbial population were recorded. Thus, bamboo plantations have great potential to enhance the biomass generation and fertility quotient of fallow lands.

喜马拉雅中部德赖地区不同竹子种植下的生物质储存潜力和土壤特性改善

本研究评估了六种竹子（Dendrocalamus hamiltonii、Bambusa nutans、Dendrocalamus asper、Bambusa bambos、Bambusa balcooa 和 Dendrocalamus strictus）的生长行为、养分吸收以及对德赖地区土壤特性的影响。B. nutans的最大丛围（8.60米）和节间长度（35.37厘米），D. hamiltonii的茎秆直径（5.70厘米）和D. strictus的每丛茎秆数（65）也显示出显著的差异。D. asper 的总地上生物量为 51.14 兆克/公顷-1，D. hamiltonii 为 362.56 兆克/公顷-1。在 0-40 厘米土层中，土壤性质的变化最为明显。在 D. hamiltonii 下，0-40 和 40-80 厘米土层的土壤容重最低（1.07 g.cm3; 1.21 g.cm3），土壤孔隙度（59.00%; 56.40%）、土壤有机碳（1.54%; 0.72%）和土壤可利用氮（228.29 kg.ha-1; 173.73 kg.ha-1）最高。此外，土壤微生物数量也明显增加。因此，竹子种植在提高休耕地的生物量生成和肥力商数方面具有巨大潜力。

期刊介绍： Colombia Forestal Journal publishes original manuscripts on themes of the forest field and various aspects of natural resources and the environment, which are discriminated in the categories of research article, review, reflection and technical notes of agreement with the stipulations of COLCIENCIAS for scientific publications. According to the classification of scientific areas of the Organization for Economic Cooperation and Development (OECD), Colombia Forestal Journal belongs to the large area of Agricultural Sciences (4), Agriculture, Forestry and Fisheries (4A) and to the discipline Forestry (4A02). Since its creation in 1978, the journal has been edited and published by the Francisco José de Caldas District University with headquarters in Bogotá. The quality of the content of the journal has been strengthened with the collaboration of national and international external evaluators in a double blind arbitration system and the dissemination has been extended by publishing manuscripts in a language different from Spanish and with inclusion in bibliographical databases such as Scopus. , DOAJ, Scielo, Redalyc, Ebsco, CAB Abstracts of CAB International, Forestry Abstracts, Ulrich''s, Latindex, Publindex. Likewise, it has academic profiles at Mendeley, Academia and Researchgate. The articles that are submitted to Colombia Forestal Journal must be original and unpublished and have not been postulated in other journals.
