Over the last decade, bamboo has emerged as an interesting plant for the treatment of various polluted waters using plant-based wastewater treatment systems. In these systems, nitrogen and phosphorous concentrations in wastewater can exceed plant requirements and potentially limit plant growth. The effects of two nutrient rates on the growth of seven bamboo species were assessed in a one-year experiment: Dendrocalamus strictus, Thyrsostachys siamensis, Bambusa tuldoides, Gigantochloa wrayi, Bambusa oldhamii, Bambusa multiplex and Bambusa vulgaris. Nutrient rates were applied with a 20:20:20 NPK fertilizer as 2.6 and 13.2 t.ha.yr(-1) NPK to three-year-old bamboo planted in 70 L containers. Morphological characters, photosynthetic responses, and NPK content in bamboo tissues were investigated. Under high-nutrient supply rate, the main trend observed was an increase of culm production but the culms' diameters were reduced. For the seven species, the above ground biomass yield tended to increase with high-nutrient rate. Increasing in nutrient rates also improved the photosynthetic activity which is consistent with the increase of nitrogen and phosphorus contents measured in plant tissues. All the bamboo species tested appears suitable for wastewater treatment purposes, but the species Bambusa oldhamii and Gigantochloa wrayi showed the higher biomass yield and nutrient removaL
在过去的十年中，竹子作为一种有趣的植物，已被应用于植物基废水处理系统，以处理各种受污染的水。在这些系统中，废水中的氮和磷浓度可能超过植物的需求，并限制植物的生长。在为期一年的实验中，评估了两种养分水平对 7 种竹种生长的影响：滇竹、暹罗甜龙竹、巨龙竹、巨龙竹、麻竹、孝顺竹和绿竹。采用 20:20:20 NPK 肥料，以 2.6 和 13.2 t.ha.yr(-1) NPK 的速率施加养分，对种植在 70 L 容器中三年生的竹子进行施肥。研究了竹子的形态特征、光合响应以及组织中的 NPK 含量。在高养分供应率下，观察到的主要趋势是竹秆产量增加，但竹秆直径减小。对于这 7 个物种，地上生物量产量随着高养分率的增加而增加。养分水平的提高也提高了光合作用活性，这与植物组织中测量到的氮和磷含量的增加是一致的。测试的所有竹种似乎都适合用于废水处理目的，但麻竹和巨龙竹的生物量产量和养分去除率更高。
