Because when the flowers fall, the ovary falls into the soil and grows strong. The folk saying goes: "Peanuts are born from falling flowers", so they are called peanuts.

Peanuts are widely used. They are not only the main dried fruit food but also the main raw material for making food, candy and oil. There are vast consumer markets both at home and abroad. Peanut kernel food has high nutritional value. It is not only rich in fat, protein, carbohydrates, but also contains a variety of vitamins and inorganic elements.

It can be eaten in a wide range of ways, including baking, stir-frying, deep-frying, boiling, and pickling. It is also the main raw material for making sugar, sauce, and canned food. The varieties of peanut kernels are also gradually expanding, which is of great significance to developing China's food industry and expanding exports.

Although peanuts are widely distributed in my country, their growth and development require a certain temperature, moisture and a suitable growth period, so the production layout is relatively concentrated.

The 14 provinces with a planting area of ??1.5 million acres from 2008 to 2012 include Henan, Shandong, Hebei, Guangdong, Liaoning, Sichuan, Anhui, Guangxi, Hubei, Jiangxi, Jilin, Hunan, Jiangsu and Fujian. Their planting area accounts for 93.5% of the country's total output and their total output accounts for 96.0% of the country's total, making them the main peanut producing areas in my country. Among them, the annual peanut planting area in 9 provinces and regions in the south exceeds 1.5 million acres, and the total planting area accounts for 35.8% of the country's total; the total output accounts for 30.3% of the country's total.

Peanuts have relatively high requirements for geological soil. When choosing peanut planting, it is advisable to choose sandy soil with relatively flat terrain and strong drainage capacity. Avoid repeated cropping of peanuts. The soil in China is not suitable for continuous planting of peanuts in the first year. It is best to choose soil where peanuts have not been planted for several consecutive years.

In addition, the soil organic matter is greater than 1.0, and the soil pH value should be between 6.5 and 7.5. The cultivation of peanuts also has certain requirements for air quality conditions, requiring the air pollution index to be less than 1. Only by meeting these geological conditions at the same time can it be possible to grow peanuts with high yields.
