Abstract

Soil profile samples collected from 11 different locations of edible bamboo growing areas in the Meghalaya and Manipur states of the North Eastern Himalayan (NEH) region of India were analysed to study the effect of different bamboo species on soil properties. The clump density was noticed highest in Teinostachyum wightii, followed by Melocanna baccifera. The highest number of culms per clump has also been recorded in M. baccifera. The highest average culm height and diameter, however, was recorded in Bambusa balcooa. All the bamboo species showed varying effects on soil properties. The highest increase in soil pH was observed in Dendrocalamus giganteus, followed by D. hookerii. Organic carbon increased in soils under all the species of bamboo. The highest increase of available N content was recorded in B. multiplex (126.5 kg/ha), followed by D. giganteus (94.0 kg/ha). The maximum build-up of exchangeable Ca + Mg was found in D. giganteus and D. hookerii. There was a reduction in available P in most of the species, the maximum being in D. hamiltonii (4.4 kg P/ha), followed by B. multiplex (3.9 kg/ha). The highest increase of available K was observed in D. hookerii (207.2 kg/ha), followed by B. multiplex. On average, D. giganteus, D. hookerii and B. nutans were found to be the better species for restoring soil fertility status in humid tropics of the NEH region, India.

印度东北喜马拉雅地区一些重要食竹物种对土壤性质的影响

本文分析了印度东北喜马拉雅地区梅加拉亚邦和曼尼普尔邦11个不同食竹产地的土壤剖面样本，以研究不同竹种对土壤性质的影响。块状密度最高的是白鸡(Teinostachyum wightii)，其次是黑胶菌(Melocanna baccifera)。每丛茎数最高的也记录在杆菌分枝杆菌中。然而，竹子的平均竿高和直径最高。不同竹种对土壤性质的影响不尽相同。土壤pH值增幅最大的是巨菖蒲，其次是虎菖蒲。各竹种下土壤有机碳含量均有所增加。速效氮含量增幅最大的是多棱草(126.5 kg/ha)，其次是巨棱草(94.0 kg/ha)。可交换Ca + Mg富集量最大的是D. giganteus和D. hookerii。速效磷在大多数物种中均有减少，其中以哈密顿布氏菌减少最多(4.4 kg P/ha)，其次是多形布氏菌(3.9 kg/ha)。速效钾增加最多的品种是虎纹田径田(207.2 kg/ hm2)，其次是多花田径田。平均而言，在印度NEH地区潮湿的热带地区，发现D. giganteus、D. hookerii和B. nutans是恢复土壤肥力状况的较好物种。
