[0003] The color of the purple sweet potato flesh is purple, rich in anthocyanins, and has high nutritional value and health care effects on the human body. Moreover, because the purple sweet potato is sweeter and tastes better than the yellow sweet potato, the demand has greatly increased. Due to Guangxi Due to the particularity of selenium-enriched soil, there are also some studies on the cultivation of selenium-enriched sweet potatoes. However, due to the unstable selenium content in the natural environment, the selenium content of purple sweet potatoes cannot be guaranteed, and the effect of selenium-enriched and high-calcium cannot be achieved. Of course, in order to achieve the effect of selenium-enriched and high

Abstract

The invention relates to the technical field of purple sweet potato planting, in particular to a method for interplanting high-calcium rich-selenium purple-sweet-potatoes. According to the method, a cassava-fermented rich-selenium high-calcium organic-fertilizer is used to improve planting soil, so that the soil is rich in selenium, high in calcium and loose, and meets the needs of purple sweet potato growing; meanwhile, the purple sweet potatoes and saxifraga stolonifera are interplanted, wherein the saxifraga stolonifera has a strong selenium conversion ability and can fully separate out organic selenium in the soil, and the rhizomes of the sweet potatoes are large and can effectively absorb the organic selenium separated out by the saxifraga stolonifera so that the organic selenium can be changed into the organic selenium of the sweet potatoes themselves and stored in the rhizomes; moreover, effective components can be extracted from natural plants and used for killing pests, so that a made insecticide can be decomposed by the environment easily and not cause pesticide residues, pollution and other harm, and the effective components of extractives have a broad-spectrum bactericidal effect to ensure that the purple sweet potatoes are not harmed by the pests.

Description

【Technical field】 [0001] The invention relates to the technical field of planting purple sweet potatoes, in particular to a method for interplanting purple sweet potatoes rich in selenium and high in calcium. 【Background technique】 [0002] Sweet potato is the fourth largest food crop in China, and it is also an important industrial raw material, feed, new energy and health crop. China is the country with the largest sweet potato planting area and the highest fresh potato production in the world, with a sweet potato planting area of ​​about 4.6 million hectares 2 , The total output of fresh potatoes is about 100 million tons, accounting for 75% of the world's total output. At present, many provinces and regions in my country regard sweet potato as the dominant crop in the adjustment of agricultural industrial structure, and sweet potato is gradually changing from a traditional food crop to a profitable economic crop. [0003] The color of the purple sweet potato flesh is p...
