Problems solved by technology

However, there are very few researches on the cultivation techniques of yacon, and there are two viewpoints in fertilization: no fertilization and only organic fertilizer application. Neither of these two fertilization methods can achieve the purpose of high-yield and high-quality yacon production.

Abstract

The invention discloses a fertilization method for yacon. The total nutrient amount of fertilizer applied per mu is: N: 20-25kg, P: 12-18kg, K: 20-25kg, and the total nutrient amount is 40%-60% of N nutrition Provided by organic fertilizers, the rest of N nutrition is provided by chemical fertilizers, and the rest is supplemented by chemical fertilizers to the total nutrient content except for the phosphorus and potassium nutrients contained in organic fertilizers; as base fertilizer application: fully irrigate the soil, after 2-3 days of irrigation, apply the Organic fertilizers and chemical fertilizers are evenly applied to the soil at one time, and then plowed and ridged; 1000-1300 yacon trees are planted per mu. Organic fertilizers and chemical fertilizers are all used as base fertilizers, which can effectively prevent the aboveground parts of the yacon fruit from growing excessively in the later stage of growth, and increase the yield; at the same time, the quality of the yacon fruit is improved, the disease resistance of the yacon fruit is improved, and the economic benefits are increased.

Description

technical field [0001] The invention relates to a method for fertilizing yacon. Background technique [0002] Yacon is a perennial dicotyledonous herbaceous plant of the Asteraceae Sunflower genus. It is resistant to strong light and medium and low temperature. It is native to the Andes in South America. It is mainly eaten raw as a fruit, and has the effects of cooling and annealing, clearing away heat and detoxifying. With the increasing demand for functional foods in society, yacon is getting more and more attention because of its special functional properties and good medicinal value. Yacon tubers contain a large amount of fructooligosaccharides, which can not only be used as high-grade fruits, but also can be developed into a new type of health food; the leaves of yacon contain a variety of phenolic acids, which have significant antioxidant effects and are useful for the treatment of diabetes and Gastrointestinal disorders have a positive impact. Therefore, yacon can ...
