Embodiment 1

[0035] In a certain navel orange base, during the flowering or fruit-bearing period of navel oranges, strip-shaped trenches are made between the rows of navel orange trees or between the trees before light rain, and the depth and width are 30 cm each. ) evenly into the dug trenches, with an amount of 20g per plant (1kg / mu), and fill it with soil after fertilization. Combined with conventional water and fertilizer management. After each growing batch of navel oranges matured, samples were taken to determine the selenium content and organic selenium ratio in the ripe navel oranges. The measurement results showed that the selenium content in navel oranges reached 5 μg / kg, and the organic selenium content was about 4.8 μg / kg, accounting for 96% of the total selenium.

Embodiment 2

[0037]In a navel orange base, during the navel orange flowering or fruit-bearing period, dig 4 to 6 radial grooves in the navel orange tree tray before light rain, with a width of about 30 cm. Fertilizer (produced by Suzhou Selenium Technology Co., Ltd., model XGP001A) is evenly applied in the dug trenches, the dosage is 40g per plant (2kg / mu), and the soil is filled after fertilization. Combined with conventional water and fertilizer management. After each growing batch of navel oranges matured, samples were taken to determine the selenium content and organic selenium ratio in the ripe navel oranges. The measurement results showed that the selenium content in navel oranges reached 10 μg / kg, and the organic selenium content was about 9.5 μg / kg, accounting for 95% of the total selenium.

Embodiment 3

[0039] In a certain navel orange base, during the flowering or fruit-bearing period of navel oranges, strip-shaped trenches are made between the rows of navel orange trees or between the plants before light rain, with a depth and width of 30 cm each, and nano-selenium plant nutrients (produced by Suzhou Selenium Valley Technology Co., Ltd., model XGP001A) is evenly applied in the dug trenches, the dosage is 80g per plant (4kg / mu), and the soil is filled after fertilization. Combined with conventional water and fertilizer management. After each growing batch of navel oranges matured, samples were taken to determine the selenium content and organic selenium ratio in the ripe navel oranges. The measurement results showed that the selenium content in navel oranges reached 20 μg / kg, and the organic selenium content was about 18.6 μg / kg, accounting for 93% of the total selenium.

Abstract

The invention discloses an organic selenium-enriched navel orange and a production method thereof. The total content of selenium in the organic selenium-enriched navel orange is between 5 and 300 mu g/kg, and the ratio of organic selenium to the total selenium is more than or equal to 70 percent. The method comprises the following step of: adding 25 to 300g of nano selenium plant nutrition agent into soil of each plant, namely 1 to 15 kg/mu in a flowering period or a fruiting period of the navel orange. The navel orange is rich in selenium elements, and the whole content is unified. By the method, the proportion of the organic selenium is improved, the problem of the stability of the content of the selenium in navel oranges which grow in different batches in the prior art is solved, the uniformity of the content of the selenium in the navel orange is ensured, and the standardized large-scale production can be realized.

Description

technical field [0001] The invention relates to fruits, in particular to an organic selenium-rich navel orange and a production method of the organic selenium-rich navel orange, belonging to the technical fields of agricultural fertilization and fruit gardening. Background technique [0002] Selenium, whose element symbol is Se, is an essential trace element for the human body. It has biological properties such as anti-cancer, anti-oxidation, anti-aging, improving human immunity, protecting cardiovascular system, and antagonizing heavy metals. Selenium deficiency can lead to the occurrence of Kashin-Beck disease and Keshan disease. According to the data released by the WHO, more than 40 countries in the world belong to low-selenium or selenium-deficient regions, and 2 / 3 of China's regions are selenium-deficient regions, and 1 / 3 of them are severely selenium-deficient regions. The Chinese Nutrition Society recommends a daily selenium intake of 50-250 μg. However, the daily ...
