The results indicated the addition B fertilizer (NPK+B) gave high potential in increasing the number of 1-yr-old bamboo and the bamboo biomass. On the other hand, the addition Mg (NPK+Mg) was beneficial in incerasing the yield of bamboo shoot. To the mean DBH (diameter at breast height) of 1-yr-old bamboo, no significant increment was observed for almost all of the treatments. The benefits analysis suggested that the annual incomes of treatments NPK+B and NPK+Mg were 293, 975 yuan (RMB)/ha more than that of NPK applied alone, respectively. In the present trials, it was also found that the effect of fertilization on bamboo growth was positively related to the parent bamboo density of Moso bamboo stands remarkably.","subitem_description_type":"Other"},{"subitem_description":"紀要論文","subitem_description_type":"Other"}]},"item_1617186643794":{"attribute_name":"Publisher","attribute_value_mlt":[{"subitem_1522300295150":"ja","subitem_1522300316516":"琉球大学農学部"}]},"item_1617186702042":{"attribute_name":"Language","attribute_value_mlt":[{"subitem_1551255818386":"eng"}]},"item_1617186783814":{"attribute_name":"Identifier","attribute_value_mlt":[{"subitem_identifier_type":"HDL","subitem_identifier_uri":"http://hdl.handle.net/20.500.12000/3636"}]},"item_1617186920753":{"attribute_name":"Source Identifier","attribute_value_mlt":[{"subitem_1522646500366":"ISSN","subitem_1522646572813":"0370-4246"},{"subitem_1522646500366":"NCID","subitem_1522646572813":"AN00250548"}]},"item_1617186941041":{"attribute_name":"Source Title","attribute_value_mlt":[{"subitem_1522650068558":"ja","subitem_1522650091861":"琉球大学農学部学術報告"},{"subitem_1522650068558":"en","subitem_1522650091861":"The Science Bulletin of the Faculty of Agriculture.
