家蚕不同杂交组合对颗粒人工饲料适应性的比较

Comparison of the Adaptability of Different Hybridized Silkworms to Different Combinations of Particles of Artificial Feed

为了选配对颗粒人工饲料适应性强的家蚕杂交组合,本文在前期试验的基础上,重点对3对杂交组合和1对对照杂交组合1-2龄期采用颗粒人工饲料饲养,3-5龄采用桑叶饲养,全面调查了各杂交组合的主要经济指标,发现供试的3对杂交组合对颗粒人工饲料的综合适应性都明显好于对照,其中"WZHG×春晖54"的生命力指标最好;"WZHG×春晖54"、"潍和×秋明"、"潍月×春晖"的全茧量、茧层量都高于对照组合"菁松×皓月"3%～6%,但茧层率没有明显差异;"WZHG×春晖54"的万头收茧量、万头茧层量成绩是最好的,即使在小蚕颗粒人工饲料育条件下,仍然分别比全龄桑叶育条件下的"菁松×皓月"高5.85%和5.22%,是小蚕颗粒人工饲料育最优良的杂交组合。

In order to select the matching pairs of silkworm hybrids adaptable to particles of artificial feed,this study,on the basis of previous trials,selected three pairs of silkworm hybrid and 1 pair as the comparison pair which were feeded with particles of artificial feed during 1-2 age,and mulberry leaf during 3-5 age.The analysis of the key economic indicators of the various hybrid combinations indicated that the tested three pairs of hybrid combination have a better adaptability to particles of artificial feed than the comparison pair,in which"WZHG × Chunhui 54" have the best vitality of the three pairs;cocoon weight,cocoon shell weight of"WZHG × Chunhui 54","Wei and × Tyumen","Wei-month × Chunhui" were 3% to 6%higher compared to those of "Ching-Song × Haoyue",but their rate of cocoon shell has no significant difference;theproduced cocoon shell weight of 10000 "WZHG × Chunhui 54" achieved the best results,5.85% and5.22% higher than that of "Ching-Song × Haoyue" with mulberry-fed conditions,even in small particles of silkworm artificial diet-fed conditions.Therefore,"WZHG × Chunhui 54" is the best hybrid combination among all the tested artificial feed silkworms.
