The Effect of Relative Humidity in the Mounting Time on the Reelability Ratio, Bave Length, and Percentage of Raw Silk

상족기 습도가 해서율, 견사장 및 생사량비율에 미치는 영향

The experiments were carried out to investigate the effect of humidity on the cocoon quality, and 4, 000 lots of cocoon pruduced fot five years in Chin yang, Ha dong, Keo chang, San chung of Kyeong nam, and Sun san, Sang ju, Young poong, An dong of Kyeong buk were analyzed. The results were summarized as follows ; 1. The reelability ration, the bave length, and raw silk ration were decreased with increasing the humidity in mounting time, and it was remarkably observed when the relative humidity was over 80%. 2. With increasing the reelability ration, the bave length, and raw silk ration were increased, and the longer the bave lenger the bave length was the higher raw silk ration obtained. 3. The average reelability ration for five years in autumn-rearing period was higher than that in spring-rearing period, but the bave length and raw silk ratio was on the contrary from the above. 4. The reelability ration of cocoon produced in the mountainous area was higher than that in the field area but the shorter the bave length, the raw silk ration had no significant difference between those.

누에 동육에 있어 여러 가지 환경요인 중 상족기 실외평균 습도가 견질에 미치는 영향을 조사하기 위하여 5년간 경남의 진양, 하동, 산청, 거창군과 경북의 선산, 상주, 영풍, 안동군에서 견검정 의뢰한 검정구 중 군, 연도, 춘추별, 각 50검정구씩 총 4,000건을 검사 항목별로 분석한 결과는 다음과 같다. 1. 상족기의 습도가 다습할수록 고치의 해상률이 낮았는데 특히 상대습도가 80% 이상에서 그 현상이 뚜렷하였다. 2. 고치의 해상률이 높을수록 견사장이 길고 생사량비율도 높았다. 3. 추잠기가 춘잠기에 비해 고치의 평균해상률은 높았으나 견사장은 짧고 생사량비율도 떨어지는 경향 이였다. 4. 평야지에서 생산된 고치가 산간지보다 견사장이 길고 생사량비율도 높았으나 해상률은 떨어지는 경향이었다.
