Embodiment Construction

[0018] Below in conjunction with embodiment the present invention is further described.

[0019] The high-yield and high-efficiency cultivation technology of Zhenba purple sweet potato focuses on six aspects, one is to grow strong seedlings early; the other is to apply enough farmyard manure; the third is to use high-ridge belts; Belt type, by strengthening the field management of each crop, it can promote high yield and high efficiency of purebred purple sweet potato or interplanting crops.

[0020] ①Guangji Organic Fertilizer

[0021] The cultivation of pollution-free purple-core sweet potatoes adheres to the principle of applying less or no chemical fertilizers, and requires a large amount of farm organic fertilizers. There are many kinds of organic fertilizers. In addition to livestock and poultry manure and seed cakes such as pigs, cattle, and sheep, various straws, withered grass leaves, and humus on the surface of forests are all good fertilizer sources. As long as the...

Abstract

The invention relates to a high-yield and high-efficiency cultivation technique of Zhenba purple-core sweet potato, comprising the following step of: leading the purple sweet potato to adopt two-layer heat preservation seedlings growth such as a small tunnel and a mulching film, wherein the width of a seed bed is about 1.5m, and the length of the seed bed in each mu of field is 7m; digging ridged grooves with the depths of 15-30cm; paving 3cm of organic fertilizer on the surface of the bed to be mixed with earth; leading gaps among potato seeds to be 3cm; covering a layer of the organic fertilizer on the potato seeds; adopting heat preservation seedlings growth such as a layer of the mulching film and the tunnel after 3-5cm of the earth is recovered; and planting and transplanting seedlings with 4-5 leaves into land for growing field crops when the height of the seedlings is more than 15cm and the air temperature is stabilized at 13 DEG C. By way of the synthesis technique such as timely early transplanting, seedling management, water management, topdressing, trash cultivation, pest control and prevention and the like, the area, the space and the photo-thermal resource can be furthest used, and the high yield and high efficiency in unit area can be realized.

Description

technical field [0001] The invention relates to a high-yield and high-efficiency cultivation technology of Zhenba purple sweet potato. Background technique [0002] Zhenba purple core potato has high edible nutritional value. In addition to the nutritional content of ordinary sweet potatoes, it is also rich in selenium and anthocyanins. Purple core sweet potato is rich in nutrition and has special health care 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 vitamins such as phosphorus and iron. Mineral elements, containing a large amount of anthocyanins with high medicinal value, purple sweet potato is one of the main raw materials for extracting anthocyanins. According to reports, anthocyanins have preventive and therapeutic effects on more than 100 diseases, and are known as the seventh essential nutrien...
