Abstract
This study was considered chances of additional income, if farmers raised silkworms in unused mulberry leaves, after harvesting mulberry, investigated yields of mulberry leaves in vinyl-house and optimal amount in raised silkworms, First, the results was investigated productions of mulberry leaves in the mulberry tree-shape of vinyl-house, T-shape harvested 7.07 kg, Y-shape was 6.55 kg, in comparison with convention of it was harvested 4.75 kg mulberry leaves/1 mulberry tree, was harvested 49%, 38% more each. Also, yields of mulberry leaves was used 302 kg when was raised 1box of silkworms in the mulberry tree-shape of vinyl-house. In other hand, yields of raising silkworms was analysed in the mulberry tree-shapes of vinyl-house, mulberry leaves of $1,000m^2$ vinyl-house mulberry tree was raised average of 3.74 boxs silkworms, in the concrete conventional-shape was 3.24 boxs, T-shape did 4.17 boxs and Y-shape was 3.83 boxs, Consequently, if the farmers of $1,000m^2$ vinyl-house mulberry tree raised silkworms with unused mulberry leaves, could get 1~1.2 million won additionally.
본 연구는 오디수확 후 버려지는 뽕잎을 이용하여 누에를 사육할 경우 추가 소득을 올릴 수 있다는 점을 고려하여 시설하우스 내 오디용 뽕나무 유인방법별 오디수확 후 뽕잎생산량과 적정누에 사육량을 구명하기 위하여 수행하였다. 먼저 오디용 뽕나무 수형별 뽕잎생산량을 조사한 결과, 뽕나무 1주당 관행은 4.75 kg 생산되는데 비해 T자형은 7.07 kg, Y자형은 6.55 kg으로 각각 49%와 38% 더 생산되었다. 그리고 오디용 뽕나무 시설재배에서 생산되는 뽕잎으로 누에 1상자를 사육할 때 소요되는 뽕잎량은 평균 302 kg으로 분석되었다. 한편 대부분 농가에서 선호하는 5령 3일 누에를 기준으로 오디용 뽕나무 시설재배 수형별 누에사육량을 분석한 결과, 10 a당 생산되는 뽕잎으로 관행 3.24 상자인 반면, T자형 4.17상자, Y자형은 3.83 상자였으며, 평균 3.74 상자 사육 가능한 것으로 분석되었다.
