Planting method of sweet potatoes

Abstract

The invention relates to the technical field of crop planting, in particular to a planting method of sweet potatoes. The method comprises the steps of adding 25-40 kg of lime powder in per mu of cultivated land and conducting deep-ploughing treatment on the cultivated land, thickening soil layers to form pieces of ridges, planting two rows of sweet potato seedlings on each ridge in a mutually staggering mode, and scientifically fertilizing fertilizer. According to the planting method of the sweet potatoes, by adding the lime powder into the cultivated land, and using a rake to conduct the deep-ploughing treatment on the cultivated land, the lime powder is effectively and sufficiently mixed with soil, and thus the purpose of preventing insect damage is achieved; on each single ridge, two adjacent rows of sweet potatoes are planted in a staggering mode, thus it is guaranteed that nutrients in a field are sufficiently absorbed, and the situation that sweet potato seedlings which are planted side by side are mutually interfered and influenced is avoided. According to the planting method of the sweet potatoes, the sweet potatoes are high in yield, developed in root system, and high in fertilizer adsorbing capacity, the insect damage is effectively prevented, root promoting and seedling protection are achieved, the sweet potato seedlings are bright in leaf, the harvested sweet potatoes are excellent in overall quality, and high in yield, and thus the planting method of the sweet potatoes is suitable for agricultural popularization.

Description

technical field [0001] The invention relates to the technical field of crop planting, in particular to a method for planting sweet potatoes. Background technique [0002] Sweet potatoes are rich in sugar, protein, cellulose and various vitamins, especially vitamin E and vitamin C. In particular, sweet potatoes are rich in lysine, while rice and flour lack lysine. Sweet potatoes can be described as the best among grains and vegetables. Europeans and Americans praise it as the second bread, former Soviet scientists say it is the future space food, and the French call it a well-deserved advanced health food. [0003] Sweet potato is not only a healthy food, but also a good medicine for curing diseases. "Compendium of Materia Medica" records that sweet potatoes have the effects of tonifying deficiency, benefiting energy, strengthening spleen and stomach, and strengthening kidney yin. Sweet potatoes are steamed, cut, sun-dried, harvested, and used as food, called potato grain...

AI Technical Summary

Problems solved by technology

However, the existing sweet potato planting technology is relatively backward and lacks systematic and scientific planting methods, which makes the overall quality of sweet potato poor and the yield low.
