Problems solved by technology

[0004] At present, there are also planting techniques for selenium-enriched strawberries, but most of them use fertilizers containing selenium elements continuously during the whole growth process, such as the technical scheme disclosed in 201510720985.X, which uses sodium selenite as selenium fertilizer, which is highly toxic , rat oral median lethal dose (LD 50 ) is 4.5mg / kg. In addition, this program needs to be sprayed repeatedly, and the amount of selenium fertilizer is large, which is not accurate enough

example 1

[0024] Strawberry takes a routine method to plant selenium-containing concentrations of 1.5 μg / ml before harvesting the selenium concentration of 1.5 μg / ml before harvest, and then the concentration of 1.5 μg / ml of aqueous ammonium chloride is further injected, according to each strain. 150 μg of selenium (after the mixing) and 50 μg of ammonium chloride sprayed, selenium raspberry can be obtained after harvest.

[0025] Wash the strawberry with water, and then analyze the selenium content in the harvested strawberry by inductively coupled plasma mass spectrometry (ICP-MS).

[0026] The selenium content was 132.1 [mu] g / kg, which was higher than the white contrast of the blank contrast in the selenium fertilizer (5.2 μg / kg).

[0027] Further, the selenium is a solution of the ammonium chloride, and it is necessary to spray it, such as a one-time spraying after mixing, it will directly lead to a decrease in fatness. Comparative experiments showed that the selenium in aque...

[0029] Other Conditions Example 1, study selenium content in strawberries planting different selenium alcohols, as shown in Table 1:

[0030] Table 1 Different selenose effect test comparison table

[0031] Numbering Selenium Selenium content in strawberry (μg / kg) 1 Selenium Glucose (Example 1) 132.1 2 Selenium fruit sugar 133.4 3 Selenium sugar 112.5 4 Selenium maltose 104.2

[0032] The above results said that the effect of serial glucose with selenium and selenium is better. Even the selenium make a little better. However, considering that selenium fruit sugar is viscous liquid, product transport packaging and transfer is more difficult, or choose a selenium to glucose is the best selenium fertilizer. This substance can be made of dry powder for easy storage. Selenizose sugar, such as selenium sucrose and maltose, and poor effect.

[0034] Other Conditions Example 1, selenium content in strawberry planted in different selenium fertilizer spraying time, as shown in Table 1.

[0035] Table 2 Different selenium fertilizer spray time effect test comparison table

[0036] Numbering Spraying time (before harvest) Selenium content in strawberry (μg / kg) 1 48 hours 63.0 2 60 hours 98.6 3 72 hours (Example 1) 132.1 4 84 hours 125.2 5 96 hours 100.5

[0037] The above results will be described, and the inventive effect is optimal in the first 72 hours before harvest.

Abstract

The invention discloses a selenium-rich strawberry planting method, and belongs to the technical field of agriculture and horticulture. A selenium substitute sugar water solution and an ammonium chloride water solution are sequentially sprayed 48-96 hours before strawberry harvesting, the selenium-rich fertilizer reaches subacidity through ammonium chloride, the subacidity environment is most beneficial to selenium absorption, and the selenium absorption rate can be increased by three times or above compared with the selenium-rich fertilizer without ammonium chloride. The method is widely applicable to planting of various strawberries, such as Hongyan strawberries, milk strawberries (Xiangji), Fengxiang strawberries, Miaoxiang No.7 strawberries, white strawberries and the like. By the adoption of the method, the strawberries picked 48-96 hours after selenium-rich fertilizer is sprayed are the selenium-rich strawberries.

Description

Technical field [0001] The present invention belongs to the field of agriculture and horticultural technology. Background technique [0002] It has the advantages of cheap and easy, biological compatibility, and other benefits based on sugar. After a long-term study, a process for selenium, related techniques such as ZL201610899676.8, a method of synthesizing nano-selenium material disclosed in ZL2016, 99676.8, and selenium glycetose has achieved kilogram production ( Ind. ENG. Chem. RES. 2020 , 59, 10763) and is widely used as selenium-rich leaves (this year's trial area has reached 1000 mu, mainly used to plant selenium-enriched rice). Compared with other inorganic selenium compounds, selenium is more secure, for example, selenium glucose to the oral monocity of rats (LD) 50 246mg / kg ( CHIN. 2020 , 31, 3276), far less sodium selenate (LD 50 = 1.6 mg / kg) security. In addition, the selenium is also used as animal feed additives to improve animal health, and this part of the w...
