赤子爱胜蚓在不同猪粪和农作物秸杆混合物中生长繁殖状况

本文研究了赤子爱胜蚓在长春市城郊不同组合的粮食猪粪、饲料猪粪和玉米、水稻秸杆混合物中生长繁殖状况,结果发现赤子爱胜蚓的质量在0 ～30 d大幅度增加,30 ～ 60 d增加减缓,60～ 90 d呈负增长趋势.赤子爱胜蚓产茧量在试验期间的总趋势是递增的.猪粪种类、秸杆种类和两者的混合比例差异对赤子爱胜蚓的质量变化产生重要影响.粮食猪粪和玉米秸杆混合物的质量比例大致在1∶1时特别适宜赤子爱胜蚓生长和繁殖.赤子爱胜蚓在饲料猪粪和玉米秸杆混合物中的日增重倍数和日产茧量多于饲料猪粪和水稻秸杆混合物.本试验结论可为城郊猪粪和作物秸杆的大规模资源化利用提供参考.

The Growth and Reproduction of Eisenia foetida in the Different Mixture of Pig Dungs and Stalks

The growth and reproduction of Eisenia foetida in different mixtures of pig(feeding on corn or feedstuff) dungs and stalks(corn or paddy) indicated that weight of E.foetida increased significantly during the period of 0~30 d,slowly during the period of 30~60 d,and then decreased from 60 to 90 days,which possibly were related with reproduction of E.foetida or available feed decreasing in different mixtures.The trend of daily cocoons was increasing in the mixtures of pig dungs and stalks.The difference of pig dungs,stalks and the percentage had significant impacts on the weight dynamics of E.foetida.The growth and reproduction of E.foetida were the largest in the mixture of pig(feeding on corn) dungs and corn stalks especially at the percentage of 50%.The fold weight increasing daily and cocoons production daily of E.foetida in the mixture of pig(feeding on feedstuff) dungs and corn stalks were more than that of pig(feeding on feedstuff) dungs and paddy stalks.The results would provide scientific evidences for the optimal utilization of pig dungs and corn stalks in the suburban of Jilin province.
