Embodiment 1

[0016] Take 1.5kg of nano-selenium aqueous solution, 7.5kg of potassium dihydrogen phosphate, 0.75kg of borax, 0.75kg of magnesium sulfate, 0.25kg of manganese sulfate, 0.75kg of calcium chloride, 0.25kg of zinc sulfate, 0.30kg of ferrous sulfate, and 0.75kg of ethylene disulfide Disodium amine tetraacetate, 1.2kg humic acid, 2kg brown sugar, 2kg L-lysine hydrochloride, 0.2kg sodium glutamate, 7.8kg EM probiotics and 74kg water were stirred and dissolved to obtain a nano-selenium content of 100kg nutrient solution mother solution at 300mg / kg. Dilute the mother liquor with water at a ratio of 1:50, 1:30, and 1:20 to obtain three different concentrations of nano-selenium probiotic compound leaf nutrient solution dilutions, which contain nano-selenium amounts of 6 mg / kg and 10 mg / kg respectively. kg, 15mg / kg. In Wangjiabaozi Village, Jiewen Town, Haicheng City, Liaoning Province, Nanguo pears, Huagai pears and Jianba pears were sprayed 4 times in early May, mid-June, mid-August ...

Embodiment 2

[0021] The nano-selenium aqueous solution consumption is increased to 2.5kg among the embodiment 1, and the amount of water added is changed into 73kg, and other component weights are constant, and stirring and dissolving obtains the 100Kg nutrient solution mother liquor that nano-selenium content is 500mg / kg. Dilute the mother liquor with water at a ratio of 1:50, 1:30, and 1:20 to obtain three different concentrations of nano-selenium probiotic compound leaf nutrient solution dilutions, which contain nano-selenium amounts of 10 mg / kg and 17 mg / kg respectively. kg, 25mg / kg. Other spraying operation is with embodiment 1.

[0022] See Table 2 for the application effect comparison table of different concentration dilutions of the 500 mg / kg nutrient solution mother solution.

[0023] Table 2

[0024]

[0025] It can be seen that as the dilution ratio decreases, the selenium content of selenium-enriched Nanguo pear, Huagai pear and Jianba pear increases. Among them, the weig...

Embodiment 3

[0027] The amount of nano-selenium aqueous solution in Example 1 is increased to 4.0kg, the amount of water added is changed to 71.5kg, and the weight of other components is constant, stirring and dissolving to obtain a 100kg nutrient solution mother liquor with a nano-selenium content of 800mg / kg. Dilute the mother liquor with water at a ratio of 1:50, 1:30, and 1:20 to obtain three different concentrations of nano-selenium probiotic compound leaf nutrient solution dilutions, which contain nano-selenium amounts of 16mg / kg, 27mg / kg, respectively. kg, 40mg / kg. Other spraying operation is with embodiment 1.

[0028] See Table 3 for the application effect comparison table of different concentration dilutions of the nutrient solution mother solution with a nano-selenium content of 800 mg / kg.

[0029] table 3

[0030]

[0031]When it can be seen that the dilution ratio is 1:50, the selenium concentration of the diluent is 16mg / kg, which is nearly the same as that of Example 2 ...

Abstract

The invention relates to a nanometer selenium probiotics composite leaf surface nutrient solution and application thereof in the production of selenium-enriched pears. A using method of the nanometer selenium probiotics composite leaf surface nutrient solution is characterized by comprising the following steps of: uniformly mixing and dissolving a nanometer selenium water solution with the concentration of 20 g / kg, L-lysine hydrochloride, sodium glutamate, humic acid, monopotassium phosphate, trace elements, brown sugar and EM (Effective Microorganisms) original liquid probiotic bacteria according to weight ratio; then diluting according to the dilution ratio of 1:(20-50) by adding water; and spraying on leaf surfaces for 3-4 times according to different growth periods of pear trees so as to obtain selenium-enriched Nanguo pears, selenium-enriched ussurian pears and selenium-enriched sharp stalk pears. Compared with the prior art, the invention not only enables the pears to be rich in selenium, but also increases the yield and enhances the quality, has integrated benefit, bright and smooth pericarp and fine and tasty sarcocarp, increases the saccharinity by 0.5-1.3 percent and the yield by 5-10 percent, prolongs the storage period by about 30 days and has the selenium content of 0.010-0.050 mg / kg, wherein the selenium content is 2-10 times more than that of a control group; and in addition, by adopting the invention, the selenium-enriched apples, the selenium-enriched peaches, the selenium-enriched grapes, the selenium-enriched cherries and the selenium-enriched strawberries can be produced.

Description

technical field [0001] The invention relates to the field of application of nano-biotechnology in agricultural production, in particular to a nano-selenium probiotic compound foliar nutrient solution and its application in the production of selenium-enriched pears. Background technique [0002] Selenium is one of the essential trace elements for the human body. Selenium participates in the formation of glutathione peroxidase, which can improve the immune function of the human body. If the human body lacks selenium, it will cause Keshan disease, Kashin-Beck disease, cardiomyopathy, cancer, hypertrophy More than 40 kinds of diseases such as blood pressure and diabetes. A large number of studies have shown that the situation of selenium deficiency in my country is very serious. There is a broad selenium deficiency belt from Northeast Heilongjiang Province through North China, Central China to the Southwest. About 22 provinces, municipalities, and autonomous regions, 72% of the ...
