摘  要:为解决氧气含量过低影响小蚕发育的问题,进行了蚕座中增氧试验。1.0 g卵量的蚁蚕,置于下底26 cm×13 cm、上底27 cm×14 cm、高4 cm的带盖塑料盒内的饲养平台上饲养,随发育情况淘汰多余的小蚕,用过碳酸钠或氢氧化钙的一种或两种的不同配比作为增氧剂,给1~2龄小蚕的饲养空间增加氧气含量,从而促进小蚕生长。过碳酸钠5.0 g+氢氧化钙5.0 g区、过碳酸钠2.5 g+氢氧化钙7.5 g区和氢氧化钙10.0 g区蚕体重增加明显,氢氧化钙的效果好于过碳酸钠。氢氧化钙用量10.0 g和30.0 g、每龄期更换1次和每天更换1次的试验区无显著差异(P>0.05)。The test of increasing oxygen content in rearing seat was carried out to deal with the development of young silkworm inhibited by too low oxygen content. The newly-hatched larva,amount to 1. 0 g silkworm egg,were reared in the plastic box with cover,bottom of 26 cm × 13 cm,upper base of 27 cm × 14 cm and height of 4 cm. The redundant young silkworm was weeded out in experiment. The oxygen content in the rearing room for 1 st and 2 nd instar silkworm was increased using different ratios of sodium percarbonate and calcium hydroxide as oxygenate,which could promote the growth of the young silkworm. The silkworm body weight increased significantly in the three treatments,5. 0 g of sodium carbonate adding 5. 0 g of calcium hydroxide,2. 5 g of sodium carbonate adding 7. 5 g of calcium hydroxide and 10. 0 g of calcium hydroxide. The results indicated that the effect of calcium hydroxide was better than that of sodium percarbonate. There was no significant difference between the dosage of 10. 0 and 30. 0 g of calcium hydroxide with replacing the reagent one time every day or every instar( P〉 0. 05).
