Problems solved by technology

[0003] At present, when people fertilize sweet potatoes, they generally use chemical fertilizers, urea, manure and other raw materials to topdress sweet potatoes. Although the effect is good, the nutrients contained in chemical fertilizers and urea are far from meeting the nutritional needs of sweet potatoes. The leaves of the sweet potato are yellow, the leaves are small, and the growth is slow. The sweet potato produced is small, light in weight, poor in disease resistance, prone to leaf spot disease, and more prone to various diseases and insect pests.

There are many traditional potato cultivation techniques, but due to factors such as different soil hardness and the influence of water during fruit expansion, the growth rate of potato is often not high, and the harvested potato is often 5-8kg / plant
