This fruit grown in the soil yields 4000 kg per mu, and farmers earn over 100,000 yuan a year from it

In rural areas, it is perfectly normal for farmers to grow this and that, and generally we all know that only sweet potatoes, potatoes, taro and the like are grown in the soil. But there is a fruit that is similar to the sweet potato in both color and appearance, and even its cultivation is like that of the sweet potato, growing in the soil. When it comes to this fruit that grows in the soil, some friends may not know what it is, and may also find it strange, since the fruits we usually eat are all grown on trees, and this is the first time we have heard of a fruit that grows in the soil. This fruit is yacon, and some farmers earn over 100,000 yuan a year by growing it.
The farmer brother Mao Yecai from Xinhua Village is the one growing this fruit that grows in the soil — yacon, which can sell for 7 yuan per jin on the market. Yacon mainly grows in provinces such as Hainan, Guizhou, Hunan and Hubei. Its flesh is fragrant when eaten, crisp and delicious, with a very good taste, and its nutritional value is also relatively high. It can lower blood sugar and lower cholesterol, helps digestion, and is a natural health product for beauty and skincare. Yacon contains more than 20 kinds of amino acids needed by the human body, as well as minerals and trace elements such as calcium, iron, potassium and selenium, and regular consumption can improve the human body's immunity. It is greatly favored by the general public, and its sales on the market are extremely good.
The loess-quality sloping land that Brother Mao is now cultivating was previously used to grow sweet potatoes. The sweet potatoes grown there were large and sweet in taste, but the returns were low. Later, after learning about yacon, he used this fertile sloping land to grow yacon. Unexpectedly, the yacon grown there had excellent quality, large size, and a very fresh, sweet and crisp taste, with each plant producing 3 kg of fruit, the highest plant producing 10 kg, and a yield of up to 4000 kg per mu. In the first year of growing yacon, after buyers came to taste it, they thought the taste was very good, so they bought it all in one go. That year, because it was the first time growing it, he planted less, but he still earned several tens of thousands of yuan.
Up to now, Brother Mao has been growing yacon for the 7th year, and the planting area has become larger and larger, expanding from just a few mu of sloping land at the beginning to more than ten mu now. In the first year of planting, he earned several tens of thousands of yuan, and now in a year he earns an annual income of more than 100,000 yuan just from growing yacon, which is higher than the returns from growing sweet potatoes. Every year, when the yacon that Brother Mao grows reaches the season for being dug out, buyers come to purchase it, and this has never changed. Because the yacon he grows is of excellent quality, for 7 years it has been the same buyer purchasing it. According to Brother Mao, the purchase price at digging time is 2.5 yuan per jin, the output value per mu is 10000 yuan, and in a year, earning over 100,000 yuan from more than ten mu of yacon is no problem.
