目的:用不同的饲养方法、饲料饲养西藏那曲冬虫夏草寄主昆虫幼虫,比较分析其结果,寻找一种幼虫生长快、活力强、成活率高、成本低的饲养方法。方法:采用自然生态放养,室内天然饲料盒养,室内盒养加盖植被草皮和室内选用饲料盒养四种方法及饲料的不同配比的方法。结果:室内天然饲料饲养和室内选用饲料盒养及室内盒养加盖植被草皮处理无论在生长速度、成活率上都明显较自然生态放养有所不同。自然放养的幼虫生长速度慢,成活率低,但饲养成本低,技术操作要求不高。盒养加盖植被草皮及自然生态放养处理未发现其它致病菌的侵害。结论:在不同条件不同的要求下可根据设定目标选择合适的饲养方法。
OBJECTIVE: To feed larvae of Cordyceps sinensis host in Tibet with different breeding methods and feeds, the results were compared and analyzed to find a breeding method for larvae with fast growth, strong vigor, high survival rate and low cost. Methods: Four methods including natural ecological stocking, indoor natural feed box raising, indoor box raising and cover with vegetation turf and indoor selection of feed boxes and different proportions of feed were adopted. Results: The natural turf feeding and indoor selection of feed box and indoor box plus cap vegetation turf treatment were significantly different from the natural ecological stocking in terms of growth rate and survival rate. Natural larvae growth slow, low survival rate, but the breeding cost is low, technical operation is not demanding. Box cover raised vegetation turf and natural ecological stocking treatment found no other pathogenic bacteria. Conclusion: Different requirements of different conditions according to set the target to choose the appropriate breeding methods.
