金蝉的功效与作用及禁忌

金蝉还有一个别名叫知了猴,就是退壳前的知了。近几年养殖金蝉的养殖项目迅速发展起来,为什么要养殖金蝉?金蝉有什么好处?下面小编给大家科普下金蝉的一些功效作用与养殖前景。

金蝉的功效与作用及禁忌

蝉蛹体内含有丰富的氨基酸、蛋白质及微量元素,中医认为蝉蜕味咸甘、性寒,可清热、熄风、镇惊。

金蝉有益精壮阳、止咳生津、保肺益肾、抗菌降压、治秃抑癌等作用。金蝉含有丰富的蛋白质,蝉蜕对治疗胃病有很大的疗效。在现代社会,人们对自身健康的重视和对生活质量的要求不断提高,金蝉无疑将成为人们所选择的绿色食品之一。

蝉花的临床研究,表明其具有降低血、尿肌酐,提高内生肌酐清除率,改善血清蛋白含量,减少尿蛋白的排出等功能。因此,对早、中期慢性肾功能不全患者疗效确切。蝉花对肾间质小管病变有较好疗效,能保护肾小管细胞Na+-K+-ATP酶,减轻细胞溶酶体和细胞脂质过氧化损伤,改善肾血流动力学,减轻内皮细胞损伤和血液凝固性。故认为蝉花能够改善肾功能。

金蝉形态特征

金蝉成虫金蝉体长40~48毫米,翅展125毫米。全体黑色,有光泽,被有金属光泽。复眼淡赤褐色。头的前缘中央及颊上方各有黄褐色斑一块。中胸背板宽大,中央有黄褐色“X”形隆起。前后翅透明。前翅前缘淡黄褐色,基部黑色,亚前缘室黑色,前翅基部1/3黑色,翅基室黑色,具一淡黄褐色斑点;后翅基部2/5黑色,翅脉淡黄色及暗黑色。足淡黄褐色。雄性腹部第一、二节有鸣器,雌性无鸣器,有听器,腹瓣很不发达,产卵器显著而发达。卵长椭圆形,微弯曲;长约2.5毫米,宽0.5毫米;乳白色,有光泽。若虫黄褐色,具翅芽,能爬行,一龄的前足即表现为明显的开掘式;末龄若虫体长35毫米,黄褐色,前足开掘式,翅芽非常发达。

金蝉的养殖前景

金蝉是纯天然、无污染的绿色野生昆虫(人工养殖的金蝉只是把前期的孵化时间缩短,整个生长过程仍然完全是野生的),不受饲料添加剂、农药、激素的污染,且高蛋白、低脂肪,很受消费者欢迎,价格连年看涨,饭店、宾馆、冷藏食品厂均会上门收购,市场前景极其广阔。金蝉养殖不需要专门建场地、场房,仅在孵化期利用闲房子加温孵化即可,成虫靠吸食树根的汁液生长,既不用投喂食物,也无需专门管理,因金蝉采食量极小,合理殖种对树术没有任何危害、金蝉种卵可从专业养殖场家购进,也可以自行采集,三年以上的杨树或果树在不影响树术生长的情况下养殖金蝉,一般每亩可殖种种条500条左右,优质种条每条约有蝉卵150-400只,管理得当24个月即可每亩产金蝉10万只左右,当前金蝉价格每只在0.15元-0.30元左右,可轻松获利万元以上。

金蝉的养殖技术

1、采卵:采卵是以秋季金蝉产卵后,一般在农历七月份左右。金蝉是以尾部小刺刺入一年生嫩枝,将卵产入枝内,多以果树等多汁树枝为主,产卵后树枝多会干枯,所以大多数下端青绿而末梢干枯的枝条都有蝉卵。

2、采后处理:将有蝉卵的枝条采集后,去除干叶,剪去两端,三十根捆成一捆,用大洗衣盆底部铺一层沙,将捆好的枝条立着放入盆内,温度保持在28——34度,湿度是保持湿润,即遇干即喷,用喷雾器照准枝条喷洒湿透为止。

3、孵化:大约十五天左右即有幼虫孵出。这时会看到有一部分幼虫在枝条上爬上爬下。大约孵化出幼虫20%的时候就要进行掩埋,埋坑选择多细软毛根的地区,以便幼虫能吸取根上的养分,最好选择在种植金银花的地块中。

4、播种:将坑挖成条形,深度以挖到多毛根处为主,宽度为一锨。将孵化好幼虫的枝条顺坑放入坑内,幼虫即自行抱住植物根系。还土时要轻、缓。还好土后不能踩,更不能浇水,以保透气。

5、采收:如有树木,多在一米处用透明胶带缠一圈,以保蝉虫不会爬高蜕变。蝉虫子播种之日起15-18个月即成成虫。

6、提示:采集蝉卵以白蜡条为主,蝉卵幼虫是以植物根系的汁液为食,所以在掩埋时最好选择多根地带。每根枝条中含蝉卵100-400只,所以每亩地以500-800枝为宜,以保成活率。用此种方法种植金蝉使原有的生长期3-15年提前到18个月,孵化期由原来的一年个月提高到35天左右,成活率由原来的6%提高到30%-60%左右。所以特别适合农村进行养殖。

7、金蝉卵的人工繁育技术:构建成虫及若虫生产设施。

除自然采获蝉卵外,可以建立纱网大棚,提供金蝉成虫产卵空间。可以利用废弃果园中的果树,重新栽植果树实生苗,周围利用水泥柱或竹棒架设成围栏,中间再拉设铁丝等,外面罩上尼龙窗纱网即可。羽化或采集的成虫在其中交配产卵,以后可以根据需要留取成虫数量,不必再从野外采集种源。

如上所述,养殖金蝉的前景非常可观,养殖金蝉成本低利润高的好项目。而且金蝉的利用价值很高,不管是药用还是食用都很受人追捧。金蝉的食用方法也很多,不管是腌制着吃还是油炸都很美味。
