FarmersIn ancient times, it was common to grow a variety of crops in order to ensure a good harvest. However, there is one crop whose seeds contain highly toxic toxicity and are cultivated in large quantities. This crop isJicama。Despite the toxicity of their seeds, their root parts are safe to eat. However, in recent years we have seen less and lessJicamaWhy is this happening?
Jicama, the scientific name is:Sweet potato, native to tropical America. Despite andSweet potatoSimilar, but their seeds, stems and leaves contain toxic substancesRotenone, harmful to the human body. Therefore, in China, we only eatJicamaThe root part. Why is this poisonous plant grown in large quantities?
JicamaThe main reason why they are cultivated in large quantities is because of their extremely high yields. In ancient times, wanting to live a good life,FarmersWe have to think about the yield of the crop. JicamaofAdaptabilityIt is very strong, resistant to both drought and barrenness and waterlogging, and does not have strict requirements for the soil, so it is suitable for cultivation in various environments. In addition,JicamaThe growing cycle is short, only 4-5 months to market, and even idle management can achieve a good harvest. Especially in some barren areas,JicamaThe yield far exceeds that of other crops, and can even yield 10,000 catties per mu. In addition,JicamaThe seeds, stems and leaves are rich in toxic substances, which were also used to make pesticides in ancient times, so they are also an important cash crop.
In the 80s of the last century,JicamaIt was once an important cash crop. Due to its high production volume, it was highly sought after at the time. Especially in that era of scarcity of materials, people paid more attention to the problem of food and clothing. JicamaNot only is it highly productive, but it also has a good taste, so it is loved by people. In addition,JicamaIt can be stored for several months even at room temperature, and longer in a cellar environment. Therefore,JicamaIt was very popular in those days. In addition to being eaten as food,JicamaThey are also sometimes eaten as fruits, especially for children, and they are one of the few crops that can provide a fruity taste. Therefore,JicamaAt that time, the sales were smooth, although the ** was low, but because of a large number of sales, there was a lot of income. Compared to other crops,JicamaThe benefits are obvious, so the growers are also more profitable.
With the development of the times,JicamaThe market demand is gradually decreasing. Now the production of many staple grains is very high, which makes itJicamaNo longer dominant in the market. In addition, competition in the fruit market has intensified, and people have more choicesJicamaNo longer competitive. At the same time,JicamaThe high yield has led to a consistently low **, making it difficult to increase the selling price, causing growers to be reluctant to plant. Due to low demand,JicamaIt is becoming less and less common in the market, but there are still a few people who are cultivating.
JicamaThe amount of planting is reduced simplyPlantationsA microcosm of the transition to modernization. Many crops are also gradually losing their market in contemporary society.
