The specific fertilizer is made from the following parts (by weight) of raw materials: 40-50 parts of charred peanut stalks, 10-15 parts of nano-calcium carbonates, and 5-8 parts of wheat malt flours. In the present invention, peanut stalks are returned to fields without harm through the charring of peanut stalks; the stalks with a large amount of nutrient elements can provide complete nutrition for crops, increase the content of organic matter in the soil, and improve the physical and chemical properties and the bioactivity of the soil; the tetrabutyl titanate is introduced to enhance the absorption of calcium; the utilization rate of the calcium fertilizer is increased, and the soil can maintain the efficiency of the calcium fertilizer thanks to the good adsorbability of biochar through the integration of nano-calcium and charred stalks, slowing the release and meeting the need for calcium fertilizers in the later stages of peanut development.
