Planting method for selenium-rich mango

Abstract

The invention relates to the technical field of fruit planting, specifically to a planting method for selenium-rich mango. The planting method comprises the following steps: 1) soil preparation and field planting; 2) fertilizer application: a step of spraying a selenium-rich foliar fertilizer every 21 to 31 days from the beginning of fruiting to fruit harvesting of a mango tree, and additionally applying a fruit strengthening fertilizer to soil until fruits are harvested, wherein the selenium-rich foliar fertilizer is mainly prepared from raw materials like Cardamine, kudzuvine root, Banqiao Codonopsis pilosulc, marjoram, Purplu Basil, garlic, sundew, sodium selenite, selenium-rich edible fungus powder, paclobutrazol, ethylene and a microbial agent; and the fruit strengthening fertilizer is mainly prepared from raw materials like decomposed farmyard manure, potassium chloride, urea, a potassium-calcium-magnesium-phosphorus fertilizer, potassium dihydrogen phosphate, realgar, pannyroyalmint, rosemary and sage; and 3) orchard management. The planting method provided by the invention has the following advantages: the harm of the residual amount of a pesticide to the human body and the environment is effectively reduced; the yield per mu and the average selenium content of mango are improved; nutrients are rich; fruit pulp is fragrant, sweet and delicious; fruits are large; fruitpeel is thin; thus, economic benefits of the mango are increased.

Description

technical field [0001] The invention relates to the technical field of fruit planting, in particular to a method for planting selenium-enriched mangoes. Background technique [0002] Mango fruit contains sugar, protein, crude fiber, minerals, protein, fat, sugar and other nutrients. The precursor carotene of vitamin A contained in it is particularly high, which is rare in all fruits. Secondly, the content of vitamin C is also high. Not low. Mango has the effects of clearing the stomach, preventing constipation, arteriosclerosis, preventing high blood pressure, beautifying the skin, and anti-cancer. In addition, the extract of mango leaves can also inhibit pyogenic coccus, Escherichia coli, Pseudomonas aeruginosa, and has the effect of inhibiting influenza virus. In addition, selenium is an indispensable trace element in the human body. Selenium and vitamin E are both anti-peroxidation substances. It has also been proved that it has a therapeutic effect on malnourished chil...

Problems solved by technology

[0003] At present, in order to plant selenium-enriched mangoes, the method of foliar spraying inorganic selenium is adopted, and its disadvantages are very obvious. First, foliar spraying requires a relatively high content of selenium fertilizer, and high-concentration selenium fertilizer increases the cost of fertilizer use; secondly, because the leaves Surface spraying, selenium fertilizer is easy to spill into the field, which will cause a lot of waste of runoff water and soil in the field

During the process of planting mangoes, due to the extensive use of inorganic chemical fertilizers and the spraying of a variety of highly toxic and long-lasting pesticides, the residues of chemical fertilizers and pesticides in mango fruits have seriously exceeded the standard. , pesticides and heavy metals will remain in the human body, which will seriously endanger human life.
