An experiment was conducted to prove the influence of free-ranging 8 geese (Anser anser domesticus)( 6 months of age, average body weight: 2.8 kg) on weeding in the camellia garden (Camellia japonica L., 1.3 a in area, planting density: 178 plants/a), consisting of control plot (a closed area: 0.4 a) and the free-ranging plot (0.9 a) from November to December in 2010 (16 days). Equisetum arvense L., Setaria glauca (L.) Beauv. and Commelina benghalensis L. were frequently observed in the camellia garden. Herbage mass of the free-ranging plot significantly decreased with advancing geese free-ranging (P<0.05), which was significantly smaller than that of the control plot at the end of free-ranging period (P<0.05). Free-ranging geese grazed Amphicarpaea edgeworthii Benth. var. japonica Oliver and Cayratia japonica (Thunb.) Gagp. wound around the camellia as well as Equisetum arvense L. and Commelina benghalensis L.. At the end of free-ranging period, the geese exhibited grazing behaviour against leaves of camellia only twice, so that the percentage of injured camellia to total trees was 0.6%. These results indicated that the free-ranging geese suppressed the weeds effectively in a camellia garden and they were helpful for weeding.}, pages = {11--15}, title = {ツバキ園におけるガチョウの除草利用}, volume = {34}, year = {2012}, yomi = {ミゾグチ, ユウコ and チカラ, ユウキ and タカヤマ, コウジ and ナカニシ, ヨシタカ and トミナガ, アキラ and キド, マリ and タウラ, イッセイ and ノムラ, テツヤ and オオシマ, イチロウ and サカタ, ユウスケ} }
