Planting method of selenium-enriched apples

Abstract

The invention relates to the technical field of agricultural planting, and in particular relates to a planting method of selenium-enriched apples. The planting method of the selenium-enriched apples comprises the following steps: selecting a land parcel; preparing a selenium-enriched biological nutrient; carrying out root system fertilization; carrying out foliar fertilization; spraying and fertilizing the selenium-enriched biological nutrient to apple leaf surfaces at a flower dropping period, a young fruit period and a medium fruit period of the apples respectively; erecting a bracket and shaping; carrying out vertical frame cultivation on dwarf and close planted apple trees, and pruning tree shapes into a free fusiform shape or a thin and long fusiform shape; harvesting at proper time. According to the planting method of the selenium-enriched apples, provided by the invention, the yield of the apples and the content of selenium can be increased. The selenium-enriched biological nutrient with different concentrations are applied at a flowering phase and a fruit phase respectively, and the utilization rate of fertilizer is improved; the selenium-enriched effect of the apples is more obvious by adopting a manner of combining fruit tree spraying and soil application. The content of the selenium in pulp of ripe apples is 35mu g / kg to 50mu g / kg; the state-specified sanitary standards of the selenium content of selenium limited fruits are met.

Description

technical field [0001] The invention relates to the technical field of agricultural planting, in particular to a selenium-enriched apple planting method. Background technique [0002] Selenium is one of the essential trace elements for the human body. Selenium participates in the formation of glutathione peroxidase, which can improve the immune function of the human body. Selenium deficiency in the human body can cause more than 40 diseases such as Keshan disease, Kaschin-Beck disease, cardiomyopathy, cancer, high blood pressure, and diabetes, so the human body can improve its health by supplementing selenium to prevent diseases. The best way is to scientifically supplement selenium-enriched agricultural and sideline products, among which selenium-enriched fruits are an indispensable member of the dietary structure, and apples, as people's favorite fruit, are an indispensable part of selenium-enriched fruits. Spraying selenium preparations on the foliage of fruit trees is a...

Problems solved by technology

Spraying selenium preparations on the foliage of fruit trees is a common way to produce selenium-enriched fruits. However, most selenium preparations on the market use inorganic selenium, such as sodium selenite, selenium dioxide, etc. Although inorganic selenium is cheap, it is safe to use The range between the toxic amount and the toxic amount is very small, and poisoning is easy to occur. In addition, the bioavailability of sodium selenite is low, and it does not increase production and improve fruit quality.
