上簇期 室外 濕度가 解舒率, 繭絲長 및 生絲量比率에 미치는 影響 = The Effect of Relative Humidity in the Mounting Time on the Reelability Ratio, Bave Length, and Percentage of Raw Silk

다국어 초록 (Multilingual Abstract)

The experiments were carried out to investigate the effect of humidity on the cocoon quality, and 4,000 lots of cocoon produced for 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 ratio, the bave length and raw silk ratio 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 ratio, the have length, and raw silk ratio were increased, and the longer the bave lenger the bave length was the higher raw silk ratio obtained.
3. The average reelability ratio 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 ratio of cocoon produced in the mountainous area was higher than that in the field area but the shorter the bave length, the raw silk ratio had no significant difference between those.
