Abstract

The invention belongs to the technical field of organic agriculture planting, and particularly relates to a high-yield planting technique for organic sweet potatoes. In the process of arranging a seedbed, thoroughly decomposed organic fertilizer is applied, sweet potatoes of a detoxified variety are selected as seed potatoes, seedlings are cultured and seeds are arrayed in inclined arrangement, seedling holes are formed at large intervals, a large seedling and a small seedling are planted in each hole, in the process of field management, plant pesticide is used for killing insects, and seedling harvesting is completed at the season of Cold Dew. In the process of planting the sweet potatoes, pesticides and fertilizers are not used. A plant leaching solution with insect killing effects, such as tripterygium wilfordii, tea seed dregs and ginkgoes, is used for soaking the seed potatoes to disinfect the seed potatoes, and at the same time, the components and the formula of the organic fertilizer are strictly controlled, so that the nutritional requirement of the sweet potatoes in the process of growth is ensured. The sweet potatoes planted by the technique disclosed by the invention have the advantages of good quality, greenness, no pollution and high yield.

Description

technical field [0001] The invention belongs to the technical field of organic agricultural planting, and in particular relates to a high-yield planting technology of organic sweet potatoes. Background technique [0002] Sweet potato (scientific name: Ipomoea batatas), also known as sweet potato and sweet potato, is the root of the annual plant of Convolvulaceae. , Alcohol production. The calorie content of sweet potatoes is very low, which is much lower than that of ordinary rice, so you don't have to worry about getting fat when eating sweet potatoes. On the contrary, eating sweet potatoes can play a role in losing weight. Sweet potatoes also contain a substance similar to estrogen, which has a certain effect on protecting human skin and delaying aging. In some developing countries, sweet potatoes are used as the staple food of residents, and are widely accepted and loved by people. Potatoes, represented by sweet potatoes in our country, are also recommended by the Chin...
