稚蠶飼育의 몇 가지 方法이 飼育成積에 미치는 影響 = The Effect of Reading Merits by Young Larval Period Treated with Several Rearing Methods

국문 초록 (Abstract)

稚蠶飼育을 對照區(S), Vinyl密着覆蓋育(A), Vinyl隔離覆蓋育(B), 箱子育(C), 유연육
(D) 자배기 치기(E)로 하여 飼育成績에 미치는 影響을 調査한 바 各 項目에 有意性은 없으나 平均間을 對比해 보면 다음과 같다.
1, 給桑回數는 對照區의 59回보다 其他處理區는 42回로 給桑勞力의 約 29%가 節減되었다.
2. 給桑量은 對照區의 33.780kg (對蟻蠶量 10g)보다 C,D,E區와는 2.720kg, A,B區와는 10.120kg의 差로 約 30%의 節約이 된다.
3. 5齡極大體量은 E,D,B,C區의 順으로 對照區보다 무거웠으며 A區가 가장 가벼웠다.
4. 減蠶比率은 對照區가 가장 높았고 C,E,D,A,B의 順으로 減少되었다.
5. 對1萬頭 上中繭 收繭量은 對照區보다 B,C,E區가 많고 D,A區가 적은 便이다.
6. 繭層比率은 거의 비슷했다.
7. 以上의 各區中 比較的 좋은 成績을 나타내고 있는 것은 箱子育(C)과 유연육
(D)을 積極權奬할 價値가 있는 方法이라고 보며
8. Vinyl隔離覆蓋育(B)은 飼育成績도 위 두 方法과 對等하며 桑葉과 勞力이 節減되는 理想的인 方法이라고 본다.
9. 零細한 養蠶農家에게는 자배기 치기가 適當한 方法이며
10. 普通飼育(S)은 今後 止揚하는 것이 좋겠고 Vinyl密着覆蓋育(A)은 앞으로 보다 더 密細한 調査와 硏究가 必要하다고 본다.

다국어 초록 (Multilingual Abstract)

This experiment was conducted to know the effect of rearing merits by young larval period treated with several rearing methods.
The rearing methods are Control, treating silkworm bed attached with Vinyl covering (A), treating silkworm bed not-attached with Vinyl covering (B), Box rearing (C), Wet straw-mat rearing (D), and jar rearing (E).
Statistical significance was not convinced in the terms.
The results are summarized as follows;
1. In term of the time of feeding mulberry, Control was 59th and other treatments were 42 th, because of other treatments were decreased 29% lower than Control on the workload of feeding mulberry.
2. Amounts of feeding mulberry were decreased for 2.720 kg in treatments of C,D and E, and for 10.120kg in treatments A and B.
3. Maxium weight of 5th instar of the treatments of E,D,B,C were revealed heavier than Control.
Treatments of E was heaviest and other treatments were revealed ordinaly results.
4. Decreasing ratio of silkworm of Control was highest and other treatments were decreased in the order of C,E,D,A and B.
5. Yielding crops of the coccon grade with B,C and E, plots and increased as compared with D,A plots.
6. Cocoon layer ratio with revealed almost equal in every plots.
7. Treatments of C,D, were revealed comparatively excellent results among each terms and were of value positively to exhort.
8. Treatment B, was almost the same results as C and D in the terms of rearing results and these could guess good rearing methods to decrease mulberry leaves and workload.
9. Treatment, E, was fit in rearing method for sericulturists of small scale.
10. Control mu t be ceused for the future, and treatment A, should seem to need minute and furthermore researches and investigation.
