Planting method of organic-selenium-rich pomegranates

Abstract

Provided is a planting method of organic-selenium-rich pomegranates. The content of selenium in pomegranates is 10-50 microgram / kg. The planting method includes the first step of soil improvement, the second step of seedling transplanting, the third step of shaping and pruning, the fourth step of fertilizing, and the fifth step of checking. For selenium-rich pomegranates produced with the method, selenium-rich fertilizer is applied 3 times in the growth cycle of pomegranates, so that the selenium absorption rate of pomegranates is increased, and the selenium-rich effect is good; besides, it is not needed to apply other chemical fertilizer any more; moreover, pomegranate trees grow vigorously, the fruit bearing rate is increased, pomegranates are plump, the pomegranate yield is increased, cost is reduced, and the planting method is suitable for large-scale production.

Description

technical field [0001] The invention belongs to agriculture—a method for planting pomegranates, in particular to a method for planting pomegranates rich in organic selenium. Background technique [0002] Pomegranate, Pomegranate family Pomegranate. Deciduous shrubs or small trees. The pomegranate tree is a rare berry native to Iran and its surrounding areas. Its fruit is colorful, its seeds are crystal clear, sweet and juicy, cool and refreshing, and has high nutritional value. The pomegranate tree is beautiful and its flowering period lasts for several months. In May and June, the flowers are in full bloom, as bright as clouds, and the flowers are red like fire, extraordinarily bright, leading the coquettish; the berries are nearly spherical, and the ripening period is in September and October. The nature is sweet, sour and warm, and has insecticidal and astringent , astringent intestines, anti-diarrhea and other effects. Pomegranate fruit is rich in nutrients, and its v...

Problems solved by technology

[0006] When adopting the first selenium-enriched fertilizer, due to the limited absorption rate of inorganic selenium by crops, most of the selenium sprayed is concentrated in the grape skin and cannot enter the grape flesh, and cannot cultivate real selenium-enriched fruits; The large amount of inorganic selenium residues caused by the conference will have a toxic effect on crops and human body. If the amount is too small, it will not achieve the effect of enriching selenium. Moreover, inorganic selenium will flow into rivers with rainwater and pollute water sources.

The second method is to plant crops in natural selenium-rich areas. This method is difficult to quantitatively control the selenium content, has geographical limitations, and is not conducive to large-scale standardized production.

When the third kind of selenium enrichment is adopted, although the absorption rate of selenium by crops can be improved, there are technical problems such as poor control of application amount, environmental pollution and high cost in one-time fertilization
