最近在网络上发现一个比较好的养殖项目,比较适合在农村养殖,农村里主要是地方都比较大,水资源也很丰富,土地面积也相对的宽阔,如果租用别人的土地也不贵,做养殖的就可以试试养殖蚯蚓,下面我们就谈谈用果渣养殖蚯蚓,养殖蚯蚓需要注意什么。
一、果渣保障土壤蓬松
土壤是蚯蚓的必须选择,如果是大量的养殖,那需要的土就更多了,当然土的选择也不能随便,既要保持蓬松度,又要保持水份,这个时候果渣就非常的适合,果渣一般都带有果核之类的,跟其他的土壤按需要比例调配就可以了。
二、果渣保障蚯蚓所需要的食物
蚯蚓在土地里面生活,吃喝拉撒都在同一个环境里,果渣能够提供大量的有机物给蚯蚓做食物,保障了蚯蚓的生长,据养殖户介绍,用果渣养殖蚯蚓,30天就能出栏了。
三,果渣比较便宜
根据养殖户介绍,果渣成本0.1元一公斤,30公斤可以出栏一公斤蚯蚓,低廉的成本能够养殖更多的蚯蚓,提高养殖蚯蚓的收益,果渣能重复利用就能不断的创造收益,待多次利用后剩下的土就成有机肥,可以自己留着种植蔬果,也可以卖给种植户或园林公司。
养殖蚯蚓时,蚯蚓上面最好盖上薄膜,但要保障通风,也可以在室内养殖。把果渣地下垫上防水布,方便回收蚯蚓,也可以防止蚯蚓外出,还能有效的保持水份。
在养殖蚯蚓的时候,也要注意几点:
一、防水
蚯蚓怕水淹,因为蚯蚓没有肺和鳃,蚯蚓以体表进行气体交换,氧溶在体表湿润薄膜中,再渗入角质膜及上皮,到达微血管丛中,所以蚯蚓长时间泡水里会导致它无法呼吸。
二、怕冷怕热
天气过热容易导致蚯蚓身体温度过高,无法呼吸而死亡,它怕冷也怕热。在0℃-5℃休眠,32℃以上停止生长,在40℃以上死亡,适宜温度为15℃-30℃,最佳温度是20℃-25℃。
三、怕盐
蚯蚓的外表黏液比较怕盐,超过一定的咸度容易导致蚯蚓脱水,最后导致蚯蚓无法呼吸走向死亡。
蚯蚓作为一种中药材,价格也越来越高了,人工养殖的也越来多,最近这两年,鲜活蚯蚓售价在5—8元左右,干蚯蚓售价更是超过100元一斤了,市场前景非常的广阔。
