Example Embodiment

[0018] Example 1

[0019] The selenium-rich apple planting method of the present invention includes the following steps:

[0020] It includes the following steps:

[0021] (1) Plot selection: The planting land should be deep, fertile, loose soil, mountainous land, dry slope land and hilly land with good water conditions. The soil organic matter content is not less than 1.5%, and the soil pH is between 6 and 7.5. The height of apple seedlings is 1~1.5m, the planting pit is 0.8mX0.8mX0.8m before planting, the subsoil is separated from the topsoil, 1200~1500kg selenium-enriched compound fertilizer is applied per mu, and the topsoil is mixed and backfilled, and filled to 20cm from the ground. The spacing between seedlings is 1.5mX3m. The selenium-enriched compound fertilizer includes the following components by weight: 40 parts of urea, 28 parts of livestock and poultry manure, 9 parts of ammonium dihydrogen phosphate, 20 parts of potassium chloride, 4 parts of potassium selenite, 7 pa...

[0030] Example 3

[0031] Different from Example 1, the selenium-enriched compound fertilizer in step (1) includes the following components by weight: 45 parts of urea, 30 parts of livestock and poultry manure, 10 parts of ammonium dihydrogen phosphate, 25 parts of potassium chloride, and selenium 5 parts of potassium acid, 8 parts of humic acid, 1 part of paclobutrazol, 8 parts of sawdust, 0.8 parts of EDTA chelated zinc. Step (2) A selenium-enriched biological nutrient includes the following components by weight: 30 parts of sodium selenite, 5 parts of compound amino acid, 10 parts of urea, 3 parts of ferrous sulfate, 20 parts of potassium dihydrogen phosphate, EM fermentation 10 parts of bacteria.

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...
