The studies were made by making 8 plots in a Ryukyu-matsu afforestation forest by artificial seedling for the purpose of continual investigations of the effects on the volume increment, quality growths, etc. of the trees with different managemental methods. 2. The investigating area is in the 79 compartment, Yona forest of the University of the Ryukyus. Seeds were sown in December 1966 and supplemental seeding was made in December 1967. The investigations were made from later a day of December 1967 to an early day of January 1968. 3. Results of the investigations are as follows : 1) The cost of afforestation was expensive. Further studies on practices have to be made to reduce the cost. 2) The percentage of supplemental seeding were expected to be 30%. 3) In one seeding hole, there were 1 to 15 seedlings, but the percentage of hole in which less than 4 seedlings are growing were 93% of the whole holes. 4) The number of holes where more than one seedling were growing was about 3600 to 7400 per hectare. 5) The heights of seedlings ranged from 0.5 to 85.0cm. But those less than 20.0cm high consisted of 95%. The average was 9.3cm. 6) The numbers of seedlings per ha in individual plots were about 6000 to 17000. 7) There was a trend that the number of seedlings in a hole was greater, the average height of them was smaller.", "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": "jpn"}]}, "item_1617186783814": {"attribute_name": "Identifier", "attribute_value_mlt": [{"subitem_identifier_type": "HDL", "subitem_identifier_uri": "http://hdl.handle.net/20.500.12000/4568"}]}, "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.
