Embodiment 1

[0034] A kind of pollution-free cultivation method of fruit type sweet potato is prepared by the following steps:

[0035] 1) Soil preparation and seedling cultivation: In a plastic greenhouse, tidy up the seedling pond, the depth of the living soil layer is more than 30cm, and the sandy soil with a pH value of 6-7, water enough water; soak the fruit-type sweet potatoes in warm water at 50°C for 15 minutes, and then treat them with Soak the seeds in the liquid for 10 minutes to obtain seed potatoes; place the seed potatoes flat, with the top flat and the bottom uneven, and the gap between the seed potatoes is sealed tightly with fine sand, covered with sawdust for 1-2 cm, covered with black plastic film, and the temperature is controlled at 16°C to grow seedlings;

[0036] 2) strong seedlings, seedling picking: select the strong seedlings with dark green leaves, no aerial roots, tall and firm seedlings, seedling length of 20-30cm, and seedling weight of 800-1050g / hundred plants...

Abstract

The invention discloses a pollution-free fruit sweet potato planting method. The method comprises the steps of soil preparation and seedling culturing, seedling toughening, seedling picking, seedling treatment, ridging and fertilizing, transplanting, top application and harvest. On the identical condition, compared with a traditional planting method, according to the pollution-free fruit sweet potato planting method, the yield is increased by 15-25% per mu (a Chinese area unit and is equal to 666.67 m<2>), and fruit sweet potatoes are good in quality, delicate and smooth in surface, even in size and high in content of starch, soluble sugar and vitamin C; according to the method, the sweet potato quality is remarkably improved, and the purpose of high yield of the high-quality sweet potatoes is achieved.

Description

technical field [0001] The invention relates to the technical field of crop cultivation, in particular to a pollution-free cultivation method of fruit-type sweet potatoes. Background technique [0002] In addition to conventional nutrients such as a large amount of starch, soluble sugar, dietary fiber, protein, fat, calcium, and iron, sweet potato tubers also contain functional nutrients such as multivitamins, glycoproteins, and dehydroepiandrosterone. It is a food that is rich in nutrition, complete, and has the functions of health care and disease prevention. According to the research of the National Cancer Prevention Institute of Japan, among the nine major anti-cancer plant products, sweet potatoes have the best anti-cancer effect, and their inhibition rates on cancer cells are: 98.7% for cooked sweet potatoes, 94.4% for raw sweet potatoes, and 93.7% for asparagus , cauliflower 92.8%, cabbage 91.4%, cauliflower 90.8%, parsley 83.7%, eggplant peel 74%, bell pepper 55.5%,...
