土豆发芽了怎么办

如题所述

当土豆刚刚发芽及部位很小时,可以将芽和芽眼挖掉一块,剩下部位还是可以吃,这时的毒素还集中在芽眼及附近的部分,毒素还没有扩展。
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。

1.发芽期:播种后20天左右幼苗开始出土。从芽萌生至出苗是发芽期,进行主茎第一段的生长,发芽期生长的中心在芽的伸长,发根和形成匍匐茎,营养和水分主要靠种薯,按茎叶和根的顺序供给。

Germination period:Seedlings began to be unearthed about 20 days after sowing. From Bud initiation to seedling emergence is the germination period, the growth of the first segment of the main stem is carried out, and the center of the germination period is the elongation of the bud, the roots and the formation of the stolons. Nutrition and water mainly depend on the seeds of the potato, and are supplied in the order of stems and leaves and roots.

2.幼苗期:25天左右幼苗长高。从出苗到第六叶或第八叶展平,即完成一个叶序的生长,成为“团棵”,是主茎第二段生长,为土豆的幼苗期。幼苗期经过的时间比较短,不论春作或秋作,只有短短半个多月。

Seedling period:Seedlings grow tall about 25 days. From the seedling to the sixth leaf or the eighth leaf, it completes the growth of a leaf sequence and becomes a "cluster tree". It is the second growth of the main stem and is the seedling period of the potato. The time passed during the young seedling period is relatively short, regardless of spring or autumn, only a little more than half a month.

3.发棵开花期:45天左右土豆苗开花。从团棵到第十二或第十六叶展平,早熟品种以第一花序开花;晚熟品种以第二花序开花,为土豆的发棵期,为时一个月左右,是主茎第三段的生长。发棵期主茎开始急剧拔高,占总高度50%左右,主茎叶已全部建成,并有分枝及分枝叶的扩展。

Flowering period:About 45 days the potato seedlings bloom. From the group tree to the twelfth or sixteenth leaf, the precocious varieties bloom in the first inflorescence; The late-ripened varieties bloom in the second inflorescence, which is the flowering period of the potato. It is about one month and is the growth of the third stem. During the initiation period, the main stem began to rise sharply, accounting for about 50 % of the total height. The main stem and leaf have all been built, and there are branches and branches.

4.结薯期:90天左右土豆可以收获。即茎块的形成期,发棵期完成后,便进入以块茎生长为主的结薯期,此期茎叶生长日益减少,基部叶片开始转黄和枯萎,植株各部分的有机养分不断向块茎输送,块茎随之加快膨大,尤其在开花期后10天膨大最快。结薯期的长短受气候条件,病害和品种熟性等影响,一般在30-50天。

Potato period:Potatoes can be harvested in about 90 days. That is, after the stem block formation period is completed, it enters the tuber growing stage, which is dominated by tuber growth. During this period, the stem and leaf growth are decreasing, the base leaves begin to turn yellow and wither, and the organic nutrients in each part of the plant are continuously transported to the tubers. The tubers then accelerate their expansion. Especially in the 10 days after the flowering period. The length of the potato season is affected by climatic conditions, disease and variety maturity, and is generally 30-50 days.

扩展资料:

1.土豆,又名马铃薯,洋山芋,茄科茄属,高15-80厘米,无毛或被疏柔毛。茎分地上茎和地下茎两部分。土豆是中国五大主食之一,其营养价值高、适应力强、产量大,是全球第三大重要的粮食作物,仅次于小麦和玉米。

2.土豆是块茎繁殖,可入药,性平味甘,可以治胃痛、痄肋、痈肿等疾病。作为食物,其保存周期不宜太长,一定要低温、干燥、密闭保存。

3.土豆的生产对温度有严格的的要求:块茎生长适温是16℃-18℃,当地温高于25℃时,块茎停止生长;茎叶生长对的适温是15℃-25℃,超过39℃停止生长。

发芽的土豆有毒,必须经过处理才能食用,否则只能将发芽的土豆种到地里。

人们所吃的土豆是它的块茎,上面有许多凹陷,称为芽眼,在芽眼内有一组腋芽,在块茎的顶端有顶芽。在土豆贮藏期间,如果存放时间长,温度较高,有阳光直射到土豆表面,都可能促使土豆长芽。

发芽时,在出芽的部位产生许多酶,酶是生物催化剂,能使贮藏的物质分解,转变为供芽生长的物质。

在这个物质转化过程中,会产生一种叫做龙葵碱的毒素,它是一种生物碱,有溶血和刺激黏膜的作用,土豆发芽处存在有一种毒素。人如果吃了发芽的土豆,就可能会出现恶心、呕吐、头晕和腹泻等不健康的中毒现状,严重时还会造成心脏和呼吸器官的麻痹,使人死亡。

当土豆刚刚发芽,还生长得不大时,可以将芽和芽眼挖掉一块,其余健康的部分还是可以吃的,因为这时的毒素还集中在芽眼及附近的部分,毒素还没有扩展。

但是,虽然经过上述处理,仍会残留一部分毒素,因此,加工时除了要挖去芽和芽根,削去绿皮,还需用水浸泡半小时后再加工食用,另外,这种土豆不宜炒丝或炒片吃,可以红烧、炖或者煮。由于龙葵碱遇酸易分解,所以烹调时可以加些醋。

把土豆贮存在低温、没有阳光直射的地方可以预防土豆长芽。此外,如果生芽过多、且土豆皮的表面已经变成黑绿色就不要再吃了,否则有损我们的健康。本回答被网友采纳
