Embodiment 1

[0031] In a certain loquat base, during the flowering or fruit-hanging period of the loquat, before light rain, at the root of the loquat, with the main root of the loquat as the center, at a radius of about 40-60 cm, dig a ring with a width of 10-15 cm and a depth of 15-30 cm. For the trench, evenly apply the nano-selenium plant nutrient (produced by Suzhou Selenium Valley Technology Co., Ltd., model XGP001A) into the dug trench at a dosage of 25g per plant (1kg / mu), and fill it with soil after fertilization. Combined with conventional water and fertilizer management. After each growing batch of loquats matured, the selenium content and organic selenium ratio in the mature loquat fruits were sampled and determined. The measurement results showed that the selenium content in loquat was up to 5 μg / kg, and the organic selenium content was about 4.75 μg / kg, accounting for 95% of the total selenium.

Embodiment 2

[0033] In a certain loquat base, during the flowering period of the loquat, dig a ring-shaped groove with a width of 10-15 cm and a depth of 15-30 cm at the root of the loquat before light rain, with the main root of the loquat as the center and a radius of about 40-60 cm. Apply nano-selenium plant nutrient (produced by Suzhou Selenium Valley Technology Co., Ltd., model XGP001A) evenly into the dug trenches, with an amount of 50g per plant (2kg / mu), and cover with soil to fill up after fertilization. Combined with conventional water and fertilizer management. After each growing batch of loquats matured, the selenium content and organic selenium ratio in the mature loquat fruits were sampled and determined. The measurement results showed that the selenium content in loquat was up to 10 μg / kg, and the organic selenium content was about 9.2 μg / kg, accounting for 92% of the total selenium.

Embodiment 3

[0035] In a certain loquat base, during the fruit-hanging period of the loquat, dig a ring-shaped groove with a width of 10-15 cm and a depth of 15-30 cm at the root of the loquat before light rain, centered on the main root of the loquat, with a radius of about 40-60 cm. Apply nano-selenium plant nutrient (produced by Suzhou Selenium Valley Technology Co., Ltd., model XGP001A) evenly into the dug trenches, with an amount of 75g per plant (3kg / mu), and cover with soil to fill up after fertilization. Combined with conventional water and fertilizer management. After each growing batch of loquats matured, the selenium content and organic selenium ratio in the mature loquat fruits were sampled and determined. The measurement results showed that the selenium content in loquat was up to 20 μg / kg, and the organic selenium content was about 18 μg / kg, accounting for 90% of the total selenium.

Abstract

The invention discloses organic selenium rich loquat and a production method thereof. The total selenium amount of the organic selenium rich loquat is 5 to 300mu g / kg, and the organic selenium is more than or equal to 70 percent of the total selenium. The method comprises a step of applying nano selenium plant nutrient in an amount of 1 to 10kg / mu for every plant of 25 to 250 grams to the soil in the flowering period or the fruiting period of the loquat. The loquat is rich in the selenium element, and has uniform integral content; and by the method, the proportion of the organic selenium is improved, the problem of selenium content stability in the loquats grown in different batches in the prior art is solved, the uniformity of the selenium content of the loquat is ensured, and standard large-scale production can be realized.

Description

technical field [0001] The invention relates to fruits, in particular to a loquat rich in organic selenium and a production method of the loquat rich in organic selenium, 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 seleniu...
