从各区收茧量来看,塑料布育均比防干纸育和普通育为高。再据茧质调查,塑料布育上茧率最高,普通育次之,防干纸育最差,唯茧层率以塑料布育最低。(四)稚蚕用桑量调查: 根据防干纸育和塑料布育,均有保持桑叶新鲜、萎蔫速度慢的优点,每日仅给桑四次,仍留有一些残桑;普通育每日给桑七次,残桑数量极少。试验结果表明,塑料布育和防干纸育稚蚕用桑量(片叶)大致相同,0.2克蚁量各为363.5—368.8克,以普通育作为100,可以节约用桑11.4—12.8%。因给桑回数减少,相应的也就节约了劳动力。
From the cocoon amount received in all districts, the plastic breeding is higher than the dry paper education and general education. According to cocoon quality investigation, the highest rate of plastic breeding cocoon, general breeding times, the worst dry paper education, only the cocoon shell rate to the minimum breeding of plastic. (D) of silkworms with mulberry amount of investigation: According to the anti-dry paper and plastic breeding, have to keep mulberry leaves fresh, wilting the advantages of slow, only four times a day to mulberry, there are still some residual mulberry; general education Seven times a day to mulberry, the amount of residual mulberry minimal. The test results showed that the amount of mulberry leaf (leaf) of plastic breeding and dry-proof paper was about the same, the amount of 0.2 gram each was 363.5-368.8 g, and the common breeding was 100, which could save 11.4-12.8% of mulberry. Due to reduce the number of back to the mulberry, the corresponding will also save labor.
