Description
Technical field
The invention belongs to agricultural fertilizer technical fields, specifically provide a kind of edible cassava for selenium-enriched food production
Selenium-enriched foliage fertilizer and preparation method thereof.
Background technology
Selenium-rich fertilizer is divided into base by method of application and applies selenium-rich fertilizer and blade face selenium-rich fertilizer.Many selenium-enriched fertilizers currently on the market are more
For tea tree, rice, fruit tree etc., and it is not especially desirable that much selenium fertilizer in the market, which apply rear effect,.Inventor Qin Ke is bright（Application
Number be 201710035059.8）, Li Qi etc.（Application No. is 201610618397.x）A kind of " selenium-enriched sweet potato fertilizer has been invented respectively
And preparation method thereof ", the selenium-enriched fertilizer of " a kind of selenium-enriched foliage fertilizer ", however selenium-rich fertilizer of its invention make it is complicated, it is inconvenient.
Up to now there has been no the selenium-enriched fertilizers efficient, convenient for making for edible cassava.
Invention content
The purpose of the present invention is overcoming drawbacks described above, provide it is a kind of efficient and easy to make, for the design of edible cassava
Selenium-enriched foliage fertilizer.
Technical scheme of the present invention：A kind of edible cassava selenium-enriched foliage fertilizer, including nutrient solution, chelating agent and surface-active
Agent, the nutrient composition include：160 parts of potassium dihydrogen phosphate, 5.5-6.5 parts of sodium selenite, 1.0 parts of boron fertilizer, water-soluble nitrogenous fertilizer
3.5 parts, 2.5 parts of organic matter.
The above-mentioned nutrient composition and proportioning of the present invention is to be designed for edible cassava, and selenium element absorption efficiency is more preferable, fertilizer
Effect is more preferable.
Further, the chelating agent includes 12.8 parts of compound amino acid, 27 parts of disodium salt disodium salt.
Disodium salt disodium salt is better compared with other chelant ties such as citric acid, humic acid.Compound ammonia
The combination of base acid and disodium salt disodium salt can further promote the absorption of selenium-rich fertilizer, can simultaneously serve as nutrients
Matter is eaten cassava absorption.
Further, the compound amino acid using dregs of beans as raw material protein hydrolysate after be made.
Further, the surfactant is twen-80.
The invention also discloses the preparation methods of above-mentioned edible cassava selenium-enriched foliage fertilizer, include the following steps：
Step S1：It is prepared by compound amino acid
Prepare 100 parts of dregs of beans as compound amino acid is made after raw material protein hydrolysate；
Step S2：It is prepared by chelating agent
12.8 parts of the compound amino acid prepared is taken, 27 parts of disodium salt disodium salt is dissolved in water, is stirred after mixing
Mix dissolving；
Step S3：It is prepared by nutrient solution
Take 160 parts of heating of potassium dihydrogen phosphate, 60 DEG C of -80 DEG C of dissolvings, 5.5-6.5 parts of sodium selenite, 1.0 parts of boron fertilizer, water-soluble nitrogenous fertilizer
3.5 parts, 2.5 parts of organic matter sequentially adds stirring and dissolving in water and obtains nutrient solution；
Step S4：Liquid is chelated to prepare
Nutrient solution with chelating agent is mixed, pH value is adjusted between 6.5-7.0, chelating is stirred at a temperature of 60 DEG C 40 minutes；
Step S5：Add in surfactant
1 part of twen-80 is added in liquid is chelated, and is settled to 600 ml.
Further, in the step S1, the concentrated sulfuric acid of the dregs of beans by the use of a concentration of 30% as protolysate, 90 DEG C-
9 hours are hydrolyzed at normal temperatures in the ratio of 4.6ml/1g dregs of beans at a temperature of 100 DEG C, and are neutralized with calcium hydroxide, so
After carry out removal filtration, later be concentrated and dried obtain compound amino acid.
The number of more than ingredient is calculated by weight.
Compared with prior art, beneficial effects of the present invention are：
1st, conducive to absorption of the edible cassava to selenium.
2nd, the chelating agent that the present invention selects, chelate effect is good, easily absorbs.
3rd, selenium-enriched foliage fertilizer production method of the present invention is simple, at low cost.
4th, the edible cassava that selenium-enriched foliage fertilizer of the invention sprays can make edible cassava fresh sweet potato root tuber reach selenium-rich standard.
Specific embodiment
With reference to specific embodiment, the present invention is further explained.
Embodiment 1
Cassava is handled with 3 kinds of different selenium fertilizer.
Processing 1 uses Se content as 25.00 mg/l Organic Selenium liquid fertilizers, and processing 2 uses Se content as 500.00 mg/
The inorganic selenium soil fertilization of kg, processing 3 is using the edible cassava selenium-enriched foliage fertilizer of the present invention.It is specific as follows：
Processing 1 sprays 25.00 mg/l Organic Selenium liquid fertilizers of selenium content, and 500 times of liquid spray；
The inorganic selenium soil of processing 2 is sodium selenite 1.5g, potassium sulphate fertilizer（K2O content 51%）350g, calcium magnesium phosphate（P）110 g,
480 g of organic fertilizer；750 kg/hm2It spreads manuer in holes；
Processing 3 uses selenium-enriched foliage fertilizer of the present invention, with 5.5 g of sodium selenite, 160 g of potassium dihydrogen phosphate, 1.0 g of boron fertilizer, nitrogenous fertilizer
3.5 g, 2.5 g of organic matter, 12.8 g compound amino acids, 27 g of disodium salt disodium salt, 1 g twen-80s are settled to 600
Milliliter is mother liquor.100 times of dilution sprays (41.86 mg/l).
Edible Cassava Cultivars SC9, ST-1 are administered respectively, Contrast on effect such as following table：
From the data in table 1, it can be seen that the edible cassava that 3 selenium-rich fertilizer of the present invention of processing spray reaches fresh sweet potato selenium-rich standard, effect stability
It is and optimal.
Embodiment 2
On the basis of embodiment 1, the selenium-rich fertilizer of the present invention and processing 3 that separately make two parts of different ratios are compared.
Processing 4 is with 6.0 g of sodium selenite, 160.0 g of potassium dihydrogen phosphate, 1.0 g of boron fertilizer, 3.5 g of nitrogenous fertilizer, organic matter 2.5
G, 12.8 g compound amino acids, 27 g of disodium salt disodium salt, 1 g twen-80s are settled to 600 milliliters as mother liquor.100 times
Liquid sprays (45.66 mg/l).
Processing 5 is with 6.6 g of sodium selenite, 160.0 g of potassium dihydrogen phosphate, 1.0 g of boron fertilizer, 3.5 g of nitrogenous fertilizer, organic matter 2.5
G, 12.8 g compound amino acids, 27 g of disodium salt disodium salt, 1 g twen-80s are settled to 600 milliliters as mother liquor.100 times
Liquid sprays (50.23 mg/l).
It is below processing 3, processing 4, handles the Contrast on effect after 5 implementations：
From table 2 it can be seen that processing 4 is good compared with 3 effects of processing, material is saved in the relatively processing 5 of processing 4（Selenium）, cost is lower, therefore,
It is optimal to handle 4 resultant effects.
It should be understood that these embodiments are only illustrative of the invention and is not intended to limit the scope of the invention.In addition, it should also be understood that,
After reading the content taught by the present invention, those skilled in the art can various modifications may be made or change to the present invention, these
Equivalent form is also fallen within the scope of the appended claims of the present application.
