Abstract
本試驗於關山鎮晚崙西亞甜橙園（初鹿系土壤，土壤肥力能限分類為G，片岩老沖積土）進行。
晚崙西亞根域調整區內深施樹皮、蛭石及珍珠砂、僅以小挖土機深挖處理四個月後即可將原先集中於地表下約20公分之根系誘引至距地表30公分以下，一年後即可將根系誘引至距地表50公分以下，並以30-45公分處最多。每年之調整區根系調查中並以施用樹皮處理的根系分布最深，根生長量也最多。晚崙西亞果園樹皮之處理，其土壤有機質含量及陽離子交換能力(C.E.C)之提高都較其餘處理為高。土壤酸鹼值經三年之後各處理間差異已不大。處理三年六個月後所得各處理之果實產量及品質未呈顯著差異，而葉片分析結果，葉片三要素除氮含量在79年9月間分析時僅達2.60-2.61%，較其餘處理皆低。往後各年亦較各非樹皮處理為低，但分析值極為接近。磷、鉀含量則各處理之葉片分析值差異不大。
The effect of modifying root region for valencia in Kuan-San plot (soil condition as Chulu series, FCC:G, Schist Old Alluvial Soils) by mixing bark compost, or vermiculite and perlite with soil, or just digging but mixing none in l2Ox5Ox6Ocm volume under tree canopy might induce root system depth as from 20 cm to 30 cm under the ground surface after 4 months and to 50 cm (concentrated from 30 to 45cm) after 1 year.
The most satisfied one was mixing bark compost treatment which caused the most and deepest root system and with the highest CEC and organic matter content in 3 years¡¦ investigation. Though the soil of the mixing bark compost treatment with the lowest soil pH just at the first year and the lowest leaf N content by leaf diagnosis among treatments was identified, there were no significant different from Leaf P and K content, fruit yield and quality of valencia fruits in all treatments during the 3 years.
