安庆专区农业科学研究所第三生产队,过去用溫床育山芋苗,年年好。他們的經驗主要是: 1.种芋选择:选择新鲜完整的、无病虫害的、无冻害和破損,以及沒发芽过的作种芋,同时薯块大小一般选六至八两重的,不要过小。2.育苗时间:一般分两批下种,第一次在2月下旬,下全部种薯的20—40%;第二次在3月上中旬全部下完。3.苗床作法:挖一东西向的长形坑,深一点二至一点五尺,宽四尺,长度不限,可按下种量来定。挖起的土堆在床北面,东西两面做成傾斜土埂,床底虽微弧形。酿热原料用新鲜锯屑、驴馬粪,切碎稻草等,分层放置,分层踏实,分层泼浇适量新鮮人粪尿(顶上一层可不浇人粪尿),厚度八寸左右,填好酿热物后,上面复盏一层二至三寸的肥沃细土,再用乱草盖好,使床温上升。如温度不够就用火炕温床,即在温床一 Anqing Prefecture Institute of Agricultural Sciences, the third production team, in the past with hotbed Yau Yang Miao, good age. Their experience is mainly: 1 species of taro choice: Choose fresh and complete, no pests, no frost damage and damage, and did not germinate as a species of taro, while the size of the potato block is generally selected six to eight two weight, do not over small. 2. Seedling time: generally divided into two batches of the next species, the first time in late February, 20-40% of all seed potatoes; the second time in the middle of March all finished. 3. Seedbed practices: dig an east-west long pit, a little bit two to one and a half feet, four feet wide, the length is not limited, you can press the species to be set. Dug up the mound in bed north, east and west made of inclined soil 埂, although the bed slightly arc-shaped. Stuffed with fresh raw materials sawdust sawdust, donkey horse manure, chopped straw, layered, layered and practical, layered pouring appropriate amount of fresh human waste (top layer can not be poured into the excrement), the thickness of about 8 inches , Fill the stuffed stuffed with heat, the above complex light a layer of two to three inches of fertile fine soil, and then covered with chaos grass, so that bed temperature rise. If the temperature is not enough to use hot ken hotbed, that is, a hotbed
