Cultivation method for sweet potatoes

Abstract

The invention relates to the technical field of crop cultivation, in particular to a cultivation method for sweet potatoes. The method comprises the following steps that 1) soil tillage is carried out, 1500-2500 kg of fertilizers are applied to per mu of soil subjected to tillage; 2) spacing division is carried out on the soil, and the spacing is 50-65 cm; 3) pits are dug, the pit depth of each pit is 4-5 cm, then sweet potato seedlings are buried in the pits, the spacing between every two sweet potato seedlings is 10-14 cm, and each pit is watered with 20 ml of water; 4) weeding is carried out, and the weeding interval is once every half month or once every 10 days; and 5) cultivation observation is carried out, and the growth details of the sweet potatoes are recorded every day and are reserved as future reference data. According to the cultivation method for the sweet potatoes, the defects that the sweet potatoes are late in mature period and general in yield in the traditional sweet potato cultivation can be overcome, the yield of the sweet potatoes is increased, the mature period of the sweet potatoes is effectively shortened, meanwhile, the sweet potato growth are recorded and reserved, reliable and real data are reserved for improving a cultivation method in the future, and the sweet potatoes are scientifically cultivated in the continuous modification process.

Description

technical field [0001] The invention relates to the technical field of crop cultivation, in particular to a sweet potato cultivation method.

[0003] Sweet potatoes are rich in protein, starch, pectin, cellulose, amino acids, vitamins and various minerals, and are known as "longevity food". The sugar content reaches 15%-20%. It has anti-cancer, heart protection, prevention of emphysema, diabetes, weight loss and other effects. Li Shizhen's "Compendium of Materia Medica" in the Ming Dynasty record...

AI Technical Summary

Problems solved by technology

The sweet potato matures late, and the yield is average. In the increasingly demanding market, it is difficult to buy delicious and cheap sweet potatoes. Therefore, a cultivation method that increases the yield of sweet potatoes and shortens the growth period of sweet potatoes is particularly important.
