土豆发芽了怎么办
芽稍大些的土豆，毒素已经扩散，而扩散的部位首先是皮层，所以对这种土豆，除了在芽眼部位挖去一块外，还应在其附近削去一块。
另外，土豆的芽并不是同时萌发的，一般是顶芽首先萌发，靠近顶芽的腋芽次之，其他部位的芽萌发较晚。如果顶部的芽长得较大，其他的芽还没有萌发，将顶部切除即可。
如果土豆芽已经长的比较大，这样的土豆已经不适合继续食用，我们可以把它做成一个小盆景，或者把它栽种到花盆中，让它自然生长，如果条件适宜，管理得当，会收获一盆的新鲜土豆，体会到种植的快乐，与收获的乐趣。
在栽种土豆过程中，也要进行简单的处理而不能把整个土豆埋在土里。首先，把土豆切成几部分，确保每一部分有两到三个芽点。分切好之后放到通风阴凉处半天左右时间，确保切口变干，防止腐烂。把通好风的土豆块埋在花盆土中，土豆整个埋入，芽叶露在外面，浇水护理。
2、龙葵碱它是一种对冷、热都较稳定的化学物质，烹饪过程中普通蒸煮炖炒是很难将其破坏的，即便是削也不能完全将其去除干净。
3、土豆在一定的温度和湿度条件下，顶芽和叶芽很容易萌发发芽时，在出芽的部位会产生很多霉，经过这些酶的作用，块镜中储存的物质会被分解，谁知转变成供氧芽生长的物质。而在这个物质转化的过程中，会产生一种龙葵素的毒素，当这种毒素进入人体后，可能会造成我们恶心、呕吐、头晕、腹泻等不适，严重时还可能会造成心脏和呼吸器官麻痹，甚至导致死亡。所以，都说发芽的土豆不能吃。
1.Sow the seeds and cut them into a bud. If you are too small, you can leave two. Put one at each point.
2.During germination, buds begin to germinate and germinate from tubers.
3.The seedling stage is 20-25 days from seedling emergence to buds.
4.During the tuber formation period, the tuber growth was divided into 3 stages. The 20-25 day from bud to flower is called early stage of stem formation. It is the second stage from the flowering to the end. The third stage is starch accumulation period, which is the end stage of tuber formation.
5.A dormant period when the tuber is formed into a dormant period. At this time, even if potatoes are placed in a suitable environment, they can not germinate. This is called physiological dormancy.
Expanding information:
Potato ( scientific name: Solanum tubosum L. ) is a perennial herb of solanaceae, with edible tubers. it is the fourth most important food crop in the world, after wheat, rice and corn. Potatoes are also called eggs, potatoes, potato, etc. tubers of solanaceae plants. With wheat, rice, corn and sorghum, it has become the world's five largest crops.
Potato originated in the Andean region of south America. the history of artificial cultivation can be traced back to the southern region of Peru from 8000 BC to 5000 BC.
