四季箱栽香椿芽新技术内容摘要:
2、: 首选当年新产红椿 6 号种子,清除杂质,搓去翘翅备用。 浸泡:用适量 45热水浸烫种子 15钟,期间用手不停搅动,使种子受热均匀,当水温降至 22,将种子捞出,放入盛有增长剂 2 号溶液的容器中,然后将容器放置于温控箱内,恒温 22浸泡 8时后,将上浮的瘪种和杂质捞出,用 25的温水漂洗干净备用。 三、恒温催芽:预先用万分之一的高锰酸钾溶液将育苗盘、生长盒洗刷干净晒干,底层铺约 1 厘米厚的珍珠岩并用水拌湿,然后将已浸泡好的种子均匀撒播于基质上,播种量为每平方米 240 克。 然后将生长盒放入 22温箱内催芽生长,每天保持淋同等温度的水 3,正常情况下 2即可萌芽,6即可采收。 四、管理和采收: 当芽长 米时,种子本身的营养难以满足椿芽迅速生长所需,要用同等比例的增长剂 2 号溶液在每次淋水后 20 分钟喷淋芽体。 当芽体长 5米时,采用光谱氩离灯每晚照射芽体,直到采收。 这样种出的商品椿芽色泽翠绿,香脆细嫩,当香椿芽体长至 8米时,应及时出售,以免椿芽老化。 采收时将种芽连根拔出,冲洗干净,精细包装,分批上市,价格高于常规蔬菜。 专利查询。四季箱栽香椿芽新技术
