对印度喜马拉亚东部3个州的经济竹种的分布、生长和生产力进行了研究。在梅加拉亚那邦,发现了牡竹属、巴苦竹和梨竹属3个经济竹种。巴苦竹是在米佐拉姆的记载,方竹属和牡竹属是在锡金记载的笋用竹。所有竹种除野生外均在庭院中栽培。据观察,竹子的产量与海拔的变化密切相关,巴苦竹最大产量出现在低海拔的而非高海拔的林分中。牡竹在梅加拉亚邦每丛生长69株,每公顷1839株,大大高于庭院种植的低海拔株数(每丛16株,每公顷303株)。而在天然林中,在高海拔总株数为每丛29株,每公顷1186株,在低海拔中每丛22株,每公顷178株。
The distribution, growth and productivity of economic bamboo species in three eastern states of Himalaya in India were studied. In Meghalayana, three economic species of bamboo, Phyllobates, Bambusa and Pear, were found. Bambusa is a record in Mizoram, and Phyllodes and Phyllostachys are bamboo shoots contained in Sikkim. All bamboo species except in the wild are cultivated in the yard. It is observed that the yield of bamboo is closely related to the change of altitude. The maximum yield of barbage is found in the low altitude rather than the high altitude. In the Meghalaya, there were 69 plants per cluster, with 1,839 plants per hectare, much higher than the low-altitude plants planted in the courtyard (16 per cluster, 303 per hectare). In natural forests, the total number of plants at high altitude was 29 per cluster, 1186 plants per hectare and 22 plants per hectare at a low altitude, 178 plants per hectare.
