Problems solved by technology

[0005] However, there are two main defects in the traditional purple potato cultivation: one is the low survival rate of potato seedlings, late potato formation, uneven seedling condition, and large differences in potato size; Seriously polluted by industry, the purple sweet potatoes produced are seriously polluted, heavy metals exceed the standard, and the quality declines, which damages people's physical and mental health

Embodiment Construction

[0019] The technical solution of the present invention is described in detail below in conjunction with specific implementation examples:

[0020] Implementation address: Baihe Township, Napo County, Baise City, Guangxi Zhuang Autonomous Region

[0021] 1. Cultivation site selection: choose a neutral sandy loam plot with deep soil layer, loose texture, flat terrain and good drainage;

[0022] 2. Soil preparation: After selecting the plot, clear the weeds in the spring, and then carry out full reclamation and loosening of the soil, plowing 40 cm deep, raking the crushed soil, and forming ridges. The distance between the ridges is 70-90 cm, and the width of the ridges is 35-40 cm. The height of the ridge is 35 cm, and drainage ditches are opened around;

[0023] 3. Apply base fertilizer: apply base fertilizer, apply 3000kg of organic fertilizer per mu, spread the fertilizer evenly on the ridge surface, and turn it into the soil layer with a hoe;

[0024] 4. Seed selection:...

Abstract

The invention discloses a cultivation method for an organic purple sweet potato and belongs to the technical field of crop cultivation. The method specifically includes cultivation land selection, land preparation, base fertilizer application, seed selection, seedling cultivation, land transplantation, field management reinforcement, timely intertillage and weeding and timely vine lifting. The method has the advantages that it can be guaranteed that produced purple sweet potatoes are pure natural, free from pollution and safe in quality and can be eaten at ease; in addition, the links of applying base fertilizer, carrying out plastic film mulching and enhancing moisture management are adopted, the survival rate of potato seedlings can reach more than 95%, the yield of the purple sweet potatoes is improved by 10% to 15%, potato blocks are even in size, and procedures are simple and the operation is easy.

Description

technical field [0001] The invention relates to the technical field of crop cultivation, in particular to a method for cultivating organic purple sweet potatoes. Background technique [0002] Purple potato, scientific name: Solanum tuberdsm, also known as black potato, the potato flesh is purple to deep purple. In addition to the nutritional components of ordinary sweet potato, it is also rich in selenium and anthocyanins. Purple potato is rich in nutrition and has special health functions. It contains about 20% protein, including 18 kinds of amino acids, which are easily digested and absorbed by the human body, including 8 kinds of vitamins such as vitamin C, B, and A, and more than 10 kinds of mineral elements such as phosphorus and iron. It contains a large amount of medicinal value and high Anthocyanins, the French scientist Dr. Masquel found that anthocyanins are natural and powerful free radical scavengers. Anthocyanins have preventive and therapeutic effects on more t...
