How to grow selenium-enriched mango

Abstract

The invention discloses a planting method of selenium-rich mangoes. The planting method is characterized by comprising steps as follows: land selection, seedling culture, field planting, pruning and trimming, nutrient and water management, orchard management and pest control. The planting method adopts a fertilizer technology such as selenium-rich bio-organic fertilizer, selenium-rich organic-liquid active fertilizer, organic fertilizer and the like, so that soil environment is effectively improved, the content of organic matters and selenium in soil is greatly increased, the selenium content of the planted mangoes is high, the mango yield is high, the detection indicates that the selenium content of the mango is 0.40-0.45 mg / kg, furthermore, according to the insecticide technology adopting botanical insecticides and botanical fungicides, the better insecticidal efficacy is realized while nutrition is guaranteed, and the economic benefit is very obvious.

Description

technical field [0001] The invention relates to a cultivation method of economic crops, in particular to a cultivation method of selenium-enriched mango. Background technique [0002] mango( Mangifera indica Linn ), mango is also called lemon fruit, mango fruit, boring fruit, honey hope, Wang fruit, ampolo fruit; it is the fruit of the mango plant of the paint family, an evergreen tree native to India. The appearance of mangoes is very interesting: some are egg-shaped, and some are round, kidney-shaped, and heart-shaped; there are various skin colors: light green, yellow, and deep red; Aroma, juicy with large pits. Mango combines the essence of tropical fruits and is known as the "king of tropical fruits". Mango fruit contains sugar, protein, and crude fiber. The precursor carotene of vitamin A contained in mango is particularly high, which is rare in all fruits. Secondly, the vitamin C content is not low. Furthermore, minerals, proteins, fats, sugars, etc. are also its...

Problems solved by technology

[0005] 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 sprinkle in the field, so just causes very big waste to field runoff water and soil; Again, often causes the residual amount of inorganic selenium to be large, and inorganic selenium has obvious poisonous effect to body, safety Low, cannot be used in the production of organic selenium-enriched agricultural products
