Problems solved by technology

The common disadvantages of both are: need to carry out selenium nutrition fortification many times, including inorganic selenium root application, spraying, etc., the operation is loaded down with trivial details, need to input larger labor costs; use a large amount of selenium in the production process, apples have a negative impact on selenium. Absorption and utilization are low, resulting in waste of selenium resources. A large amount of selenium flows into the farmland ecosystem, which is likely to cause selenium pollution; in the production process, there are steps of spraying inorganic selenium leaves. Plant leaves are not the main absorption organs, and the absorption capacity is limited. Inorganic selenium is highly toxic, and residual inorganic selenium poses a greater safety hazard

Embodiment 1～9

[0037] In a certain apple planting base, after apple pruning in winter, choose 70 apple trees, embodiment 1 is 1kg / mu according to the consumption of nano-selenium plant nutrient, every 10 trees are an experimental group, according to the row spacing conversion of apple trees to The amount of implementation per plant. After fully mixing the nano-selenium plant nutrient and calcium sulfate according to the mass ratio of 20:1, excavate a circular ditch 80-100 cm away from the root of the apple tree, with a width of 50 cm and a depth of 50 cm. Sprinkle the mixed nano-selenium plant nutrient and calcium sulfate into the ditch, cover with soil and bury it. After the apples were harvested, the selenium content in the apples of each group was detected.

[0038] Embodiment 2~7 other conditions are identical with embodiment 1, difference is the consumption of nano-selenium plant nutrition, the consumption of nano-selenium plant nutrition is successively 3,5,10,20,40, 50kg / mu.

Embodiment 8

[0040] In an apple planting base, after the apples were pruned in winter, 10 apple trees were selected, and the dosage of the nano-selenium plant nutrient was 10kg / mu, and the amount of implementation per plant was converted according to the row spacing of the apple trees. After fully mixing the nano-selenium plant nutrient and calcium sulfate according to the mass ratio of 20:2, excavate a ring-shaped ditch 80-100 cm away from the root of the apple tree, with a width of 50 cm and a depth of 50 cm. Sprinkle the mixed nano-selenium plant nutrient and calcium sulfate into the ditch, cover with soil and bury it. After the apples are harvested, the selenium content in the apples is detected.

Embodiment 9

[0042] In an apple planting base, after the apples were pruned in winter, 10 apple trees were selected, and the dosage of the nano-selenium plant nutrient was 10kg / mu, and the amount of implementation per plant was converted according to the row spacing of the apple trees. After fully mixing the nano-selenium plant nutrient and calcium sulfate according to the mass ratio of 20:5, excavate a circular ditch 80-100 cm away from the root of the apple tree, with a width of 50 cm and a depth of 50 cm. Sprinkle the mixed nano-selenium plant nutrient and calcium sulfate into the ditch, cover with soil and bury it. After the apples were harvested, the selenium content in the apples of each group was detected.

[0043] The detection results of Examples 1-9 are shown in Table 1.

Abstract

The invention discloses an apple rich in organic selenium and a cultivation method of the apple rich in organic selenium. The apple rich in organic selenium has the total selenium content of 10-500 mu g / kg and the ratio of organic selenium in the apple is not less than 70%. The method is realized by cultivating according to a normal apple planting method, and the method is characterized by also comprising the step of: applying a nano selenium plant nutritional agent at one or more stages of stage after winter pruning, state before blooming, blooming stage, fruiting stage and fruit swelling stage in the apple growth cycle. According to the apple rich in organic selenium obtained by the method disclosed by the invention, the state of selenium is safer and more effective, the selenium content achieves target content, and apple rich in organic selenium of different selenium-rich standards can be obtained by adjusting and control.

Description

technical field [0001] The invention relates to a method for producing selenium-enriched apples, belonging to the technical field of apple cultivation. technical background [0002] Selenium is an essential trace element for humans and animals. It has biological properties such as scavenging free radicals, anti-oxidation, anti-aging, anti-cancer, enhancing immunity, and antagonizing heavy metals. The data released by WHO also shows that more than 40 countries in the world belong to low selenium or selenium deficient areas. The source of selenium in the human body mainly depends on dietary intake. Selenium-enriched agricultural by-products are an effective way for the human body to supplement selenium. Therefore, selenium-enriched technology is a hot area of ​​research and development by scientists. [0003] The selenium content of crops is generally affected by factors such as crop species, soil selenium content, some physical and chemical indicators, and agronomic manageme...
