Problems solved by technology

[0004] However, although the above method has certain advantages, it also has its limitations, because the planting field it uses is excellent cultivated land with high soil fertility, and it is mainly for sweet potato breeding. It has not been utilized, and it is necessary to develop a high-yield cultivation method suitable for hilly drylands to improve the utilization rate of hilly drylands in my country

Abstract

The invention belongs to the technical field of cultivation of sweet potatoes and discloses a high-yield cultivation method for organic sweet potatoes in drought hill regions. The method comprises the following steps: preparing seedlings, leveling soil in the drought hill regions, ridging, building a greenhouse, applying a base fertilizer, transplanting the seedlings and the like, wherein the base fertilizer is prepared from the following components in parts by weight: 1000 parts of chicken manure, 80-100 parts of wheat hulls and 80-100 parts of salvia miltiorrhiza residues; the seedling transplanting fertilizer is prepared from the following components in parts by weight: 100 parts of chicken manure and 100-150 parts of salvia miltiorrhiza juice. The method is suitable for cultivation in the drought hill regions, the utilization rate of the drought hill regions in China is improved, and the production efficiency of the sweet potatoes is high. Due to ridge and furrow irrigation, water permeates from the lower side of the ground, so that the water is provided for rapid growth of the sweet potatoes, and evaporation loss of excessive surface water is avoided. Therefore, the yield of the sweet potatoes in drought hill regions is improved by 15-25%, and the growth cycle of the sweet potatoes is shortened by 15 days.

Description

technical field [0001] The invention belongs to the technical field of sweet potato cultivation, and in particular relates to a method for high-yield cultivation of organic sweet potatoes in hilly dry areas. Background technique [0002] Sweet potatoes are native to South America and are divided into white, yellow and purple varieties. They are one of the common food materials in daily life. Oleic acid, nicotinic acid and other vitamins, these nutrients can speed up the digestion of the stomach and the metabolism of various organs in the body, which is of great benefit to improving the health of the human body. Because of its strong resistance to stress and vigorous growth, it is widely used in my country Widely planted. [0003] When the sweet potato is cultivated, the potato seedlings are usually first bred from tubers, stems, etc., and then the potato seedlings are planted in the field to finally grow and mature. The authorized announcement number is CN 103703974B, and th...
