① 薯仔长在什么地方

庄稼地里

② 薯仔适合生活在什么地方

薯仔适合生活在气候冷凉、光照强度大、土壤排水通气良好的地方。

薯仔性喜冷凉,不耐高温,生育期间以日平均气温17℃~21℃为适宜。光照强度大,叶片光和作用强度高,块茎形成早,块茎产量和淀粉含量均较高。

薯仔植株对土壤要求十分严格,以表土层深厚,结构疏松,排水通气良好和富含有机质的土壤最为适宜,特别是孔隙度大,通气度良好的土壤,更能满足根系发育和块茎增长对氧气的需要。

马铃薯(薯仔)的习性:

1、马铃薯生长期

马铃薯是轮作制中的肥茬,宜成为其他农作物的前茬。马铃薯的全部生长期为60天~120天,其生育期较短,种植能力较大,不受地质因素的影响,只有保证马铃薯的种植时间就能进行播种。同时马铃薯也是补救农作物的最佳粮食之一。

2、马铃薯适应性

马铃薯在生长过程中具有较强的适应能力,只要土壤成分在PH4.8-7.1就可,在种植过程中要挑选使用肥沃的沙质作为马铃薯生长的土壤,从而提高马铃薯的产量与质量。

同时在种植过程中,还要保证适当的空气温度,补充足够的阳光日照,从而增加马铃薯的抵抗力,促进我国农业技术快速发展。

④ 胖乎乎的薯仔生长在哪里

薯仔学名马铃薯,也开花结籽,种子就是小薯仔,有高梁粒大小。 如果种植种子,播种上不好保墒(种深了苗顶不出土,种浅了易干),种籽小而幼苗弱,苗期不好管理又收获甚微。 而其块茎――薯仔。用来切块种植具有节约用种,打破休眠,出苗迅速整齐的特点,能获得高产。 薯仔切块后,块茎内引起休眠的脱落酸含量减少,刺激生长的赤霉酸含量增加,同时,酶活性增强,促进了各种物质的降解,因而芽部细胞迅速分裂,使生长推逐渐伸长萌发成幼芽。

⑤ 薯仔的生长过程

薯仔生长周期:

1. Dormancy period

Tuber dormancy begins at the tip of stolon and stops polar growth and tubers begin to expand. The length of dormancy period is related to the storage of tubers, whether seedlings can emerge in time after sowing, and therefore to the yield. The length of potato dormancy period is greatly affected by storage temperature. Under the condition of about 26 degrees Celsius, the dormancy period varies from about one month to more than three months e to different varieties. At temperatures of 0-4 degrees Celsius, potatoes can remain dormant for a long time. The dormancy process of potato is determined by the direction of enzyme activity and closely related to environmental conditions.

2. Germination period

The growth of potato begins with the germination of buds on tubers. Only when the dormancy of tubers is relieved, can the buds and seedlings grow obviously. From germination to emergence, germination is the first stage of main stem growth. The center of growth ring germination is the elongation of buds, rooting and stolon formation. Nutrition and moisture are mainly supplied by seed potatoes in the order of stems, leaves and roots. The speed and quality of growth depend on the environmental conditions required for seed tuber and germination. The ration of growth varies from one month to several months, depending on the dormancy characteristics, cultivation season and technical measures.

3. Seedling stage

From emergence to flattening of the sixth or eighth leaf, the growth of one leaf sequence is called "tufted tree", which is the second growth stage of the main stem and the seedling stage of potato. The ration of seedling stage is relatively short, whether spring or autumn is only half a month.

4. Initiation stage

From cluster to twelfth or sixteenth leaves, early-maturing varieties blossom in the first inflorescence; late-maturing varieties blossom in the second inflorescence, which is the growing period of potato, about one month, and the growth of the third segment of the main stem. The main stem began to rise sharply at the beginning, accounting for about 50% of the total height; the main stem and leaves had been completed, and there were branches and branches and leaves to expand. The root system continues to expand, the tuber expands to the size of pigeon eggs, and there is a turning point of growth center in the growing stage. The end point of the turning stage is to balance the ratio of stem and leaf dry matter mass to tuber dry matter mass.

5. Potato stage

The tuber formation period. After the completion of the growing season, the tuberous stem stage is the main stage of tuber growth. During this period, the growth of stem and leaf was decreasing day by day, the base leaves began to turn yellow and withered, the organic nutrients of each part of the plant were continuously transported to the tuber, and the tuber enlarged rapidly, especially 10 days after flowering. The length of the tuber period is governed by climatic conditions, disease and cultivar maturity, usually 30-50 days.

1、休眠期

块茎休眠始于匍匐茎尖端停止极性生长和块茎开始膨大的时刻。休眠期的长短关系到块茎的贮藏性,关系到播种后能否及时出苗,因而关系到产量的高低。马铃薯休眠期的长短受贮藏温度影响很大,在26摄氏度左右的条件下,因品种的不同,休眠期从1个月左右至3个月以上不等。在温度为0-4摄氏度的条件下,马铃薯可长期保持休眠。马铃薯的休眠过程,受酶的活动方向决定,与环境条件密切关联。

2、发芽期

马铃薯的生长从块茎上的芽萌发开始,块茎只有解除了休眠,才有芽和苗的明显生长。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。生长的速度和好坏,受制于种薯和发芽需要的环境条件。生长所占时间就因品种休眠特性、栽培季节和技术措施不同而长短不一,从1个月到几个月不等。

3、幼苗期

从出苗到第六叶或第八叶展平,即完成1个叶序的生长,称为“团棵”,是主茎第二段生长,为马铃薯的幼苗期。幼苗期经过的时间较短,不论春作或秋作只有短短半个月。

4、发棵期

从团棵到第十二或第十六叶展开,早熟品种以第一花序开花;晚熟品种以第二花序开花,为马铃薯的发棵期,为时1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。根系继续扩大,块茎膨大到鸽蛋大小,发棵期有个生长中心转折阶段,转折阶段的终点以茎叶干物质量与块茎干物质量之比达到平衡为标准。

5、结薯期

即块茎的形成期。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落,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,尤在开花期后10天膨大最快。结薯期的长短受制于气候条件、病害和品种熟性等,一般为30-50天。

马铃薯块茎膨大期常见的问题有:

1、植株封垄,晚疫病、早疫病发病严重。

2、浇水不足、棚温控制差,导致马铃薯叶片卷曲,植株萎蔫。

3、低温、冻害造成马铃薯叶片萎蔫、焦枯,生长不良。

4、偏施氮肥导致马铃薯植株徒长,薯块小。
