蠶寶寶和冬蟲夏草合體了

    溧陽這家合作社種桑養蠶搞出了大名堂,不僅桑樹新品種獲得了國家發明專利還讓蠶寶寶和冬蟲夏草“合體”

農民信息網 www.6i47.com   冬蟲夏草這味中草藥,如果與其他生物結合,會有什么樣的神奇結果?溧陽天目湖蠶桑專業合作社與中科院江蘇省植物研究所合作,成功研制出了蠶蟲草。

  蟲草菌座與活蠶或蠶蛹“合體”,長出了蠶蟲草

  蠶蟲草是以冬蟲夏草的菌座為依托,把活蠶或蠶蛹與菌座嫁接,約摸一個月時間就能長出蠶蟲草。其生長過程比真正的冬蟲夏草時間要短,價格還低,每公斤4000元。長出來的蠶蟲草由植物研究所回收進行深度加工,做成保健品。

  合作社理事長夏安扣介紹,蠶或蠶蛹中含有大量的蛋白質,為蠶蟲草的順利生長提供了非常有利的條件。起初,大家把高溫滅菌后的蠶蛹嫁接在菌種里,經過多方試驗之后發現,用雄性活蠶來嫁接冬蟲夏草菌座,長成的蠶蟲草活性更好。

  除了白色,能不能使蠶吐出彩色的絲?這是蠶桑業人士努力了很多年的課題。要想使蠶吐出彩色的絲,有兩種方式,一種是改變家蠶的基因結構,還有一種是給蠶吃帶有植酸酶色素的食物。使用前一種方式結出來的彩色繭子,即使織成絲織物下水洗在陽光下晾曬,也不會掉色。

  在大家疑惑的眼光中,合作社引進了一種能夠吐出綠色絲的新蠶種“草原×神韻”,它是科研人員通過基因定位改變家蠶結構培育出來的。養殖新蠶種“草原×神韻”的社員第一年收益就增加,彩繭售價超過了普通白色繭,彩繭繅成的絲還免去了上染料的過程,更為環保。

  100多種果桑,其中有能長到14厘米的桑葚

  在溧陽市農民信息網系統,一共有兩位享受國務院政府特殊津貼的專業技術人員,其中一位就是夏安扣,他是2010年度享受這一特殊津貼的人員之一。

  夏安扣大學時學的蠶桑專業,工作后一大半的時間在跟蠶桑打交道,一輩子只做了兩件事:種桑、養蠶。即便退居二線了,即使2008年蠶繭價格劇跌大批農戶砍掉了桑樹,他還是離不開鐘愛的蠶桑事業。

  在上個世紀90年代,蠶桑是溧陽市的重要產業,種桑養蠶賣繭是農民致富的最佳途徑,高峰期時,溧陽全市有10——12萬畝的桑田,繅絲廠多達5家。隨著時代的發展,經濟結構的調整,蠶桑業日益萎縮。現在,只有橫澗和平橋兩地還有部分農戶在從事傳統蠶桑業,桑園面積加起來也就一萬畝出頭,他們多數都是合作社的社員。

  夏安扣介紹,傳統的桑樹品種和蠶桑業鼎盛時期的改良桑樹品種,主要是為了采桑葉,桑葉多了桑果就結得少了甚至不結果,不過,現在這種矛盾已經得到了緩解。夏安扣與中國農業科學院合作,經過10年時間選育出了一種果葉兩用桑樹新品種,還獲得了國家發明專利。這個新品種的桑葉產量比普通桑樹增加了20%,每畝還能產3000—4000斤桑葚。

  在合作社的桑園基地里,光引進的果桑品種就有100多個。其中有一種果桑,樹苗就要100元一棵,它結出來的桑果可以長到14厘米,跟一支香煙的長度差不多。桑園的采摘游也對游客開放,去年第一年對外開放時反響不錯,今年還將繼續,預計5月中下旬開園,游客在這里能吃到各種不同顏色和品種的桑葚。
