Description
本发明属于鸟类人工繁殖技术。
灰喜鹊能扑食多种农、林害虫,如松毛虫、金龟子、蝗虫、刺蛾等,特别对松毛虫有很强的抑制作用,一只灰喜鹊每年可扑食1.5万头松毛虫,目前,虽然人工驯养灰喜鹊已获成功,但由于雏鸟的虱螨危害和蛇、猫头鹰等扑食,使灰喜鹊的人工繁殖屡遭失败,严重影响了灰喜鹊的开发利用。
本发明目的为了提供一种杀灭鸟巢虱螨,阻止蛇类扑食,驱赶猫头鹰并可提高灰喜鹊繁殖能力的一种繁殖技术,简便易行,有利于推广普及。
本发明是这样实现的:
选择地势平坦,附近有水源,周围有树林的环境,用尼龙或金属网罩建造高4米、长宽各10米左右的鸟笼,鸟笼一侧开门,笼内罩几棵枝叶繁茂的常绿树,并设饲料台和饮水池,鸟笼一角设栖息架。
每年三月上旬,当灰喜鹊进入繁殖季节前在鸟笼四壁、笼顶及笼内外树叉处,设置人工巢架,人工巢架四周为35厘米长、25厘米宽的木板,底部用木条钉成透气板条,巢架周围投放羽毛、头发、细树枝、布条等供亲鸟筑巢用的杂物,为防止蛇类爬行动物的侵害,在设置鸟巢的树干基部沿树干一周捆扎一个光滑材料做成的防护圈,本实施例材料为塑料薄膜,高为50厘米的防护圈,防护圈还可以是沿树干一周均匀布设锋利针刺或刀片或涂有触杀剂的隔离环,还可以油毛毡或薄铁皮等光滑防雨材料做成开口向下的漏斗状防护罩,防护罩半径为50厘米,开口朝下与树干成50~55°夹角。
灰喜鹊每年三月中,下旬进入配偶期,四月底五月初营巢,五月上旬产卵,每巢产卵5~8枚,孵卵期为15~16天,雏鸟孵出后,要及时对鸟巢进行高温消毒处理,当雏鸟孵出2~3天时,在晚上将雏鸟从巢内抓出,置于保温处,一般为27℃~30℃,用开水彻底淋巢,实行高温消毒,待巢内温度降至30℃时,再在巢底垫上干树叶和草纸,最后将雏鸟轻轻放回原巢,过5~6天,用同样方法再将开水淋冲鸟巢一次,为防止猫头鹰等夜行猛禽的扑食,鸟巢附近要悬挂红光驱赶器,本实施例的驱赶器是由40~60瓦的红色电灯泡构成,当雏鸟发育到14~15日龄时,将雏鸟从巢内取出置于27℃~30℃的养雏室内与亲鸟隔离饲养,可促使亲鸟当年进行第二次营巢产卵,应用本技术一对灰喜鹊每年可繁殖雏鸟12只以上。
