Abstract
Effects of paper mill sludge-fertilizers were investigated on the growth performances of tree seedlings under field conditions. Two types of sludge-fertilizers applied were an organic sludge compost and a processed sludge-pellet fertilizer strengthened with several components of organic and inorganic nutrients. Three species of tree seedlings studied were ibota privet(Ligustrum obtusifolium) and yellow poplar(Liriodendron tulipifera) of 1-0 year seedlings and also eastern white pine(Pinus strobus) of 2-2 year seedlings. Nitrogen and phosphorus contents of plot soil treated with sludge compost+sludge-pellet fertilizer+sludge-pellet fertilizer plot were increased to 8 times and 2.6 times as those of control plot, respectively. The growth performances of root collar diameter and seedling height were repeatedly measured up to five times through the growing season and the results were analyzed statistically by analysis of variance of randomized block design and Duncan's multiple range test. The growth performances of dry weight were measured after last fifth measurements.
제지슬러지 비료의 포장 시비에 따른 묘목 생육 효과를 조사하였다. 시비에 쓰인 두가지 슬러지비료 중 하나는 슬러지퇴비이며 다른 한 가지는 슬러지에 몇가지 유,무기양교를 첨가하여 펠렛 형태로 성형한 것이다. 시비 처리 유형은 총 6가지로 슬러지퇴비, 슬러지퇴비+슬러지펠렛비료, 슬러지퇴비+슬러지펠렛비료 2회시비, 슬러지펠렛비료, 슬러지펠렛비료 2회시비 및 무시비구로 구분되었다. 연구 대상 수종은 3가지로 관목성 활엽수인 쥐똥나무와 교목성 활엽수인 튜립나무 각각 1-0묘, 침엽수로 스트로브잣나무 2-2묘를 사용하였다. 묘목은 새로 개간하여 양료가 거의 없는 척박한 포지에 수종 별, 처리 별로
