Embodiment 1

[0053] ① Configuration solution: dissolving sodium selenite in 75% ethanol solution to configure a sodium selenite solution with a mass fraction of 12.5%; weigh chitosan and dissolve it in distilled water to configure a mass fraction of 8% chitosan solution;

[0054] ② Take 50ml of chitosan solution and 40ml of sodium selenite solution prepared in step ①, mix the two, add 10mg of surfactant sodium dodecylsulfonate, and stir magnetically for 30min;

[0055] ③Pulse ultrasonication for 15min at room temperature to obtain a crosslinked and uniformly dispersed chitosan-selenium nanosphere suspension.

Embodiment 2

[0056] The experimental effect of embodiment 2 leaf spraying, root application reagent

[0057] Leaf spray: Foliar fertilization is an indispensable auxiliary measure in fruit fertilization, and it has been used as a routine measure in the production of high-quality fruit. The nutrient absorption of foliage spraying is faster than that of soil fertilization, which can quickly overcome the nutrient symptoms of fruit trees. The amount of nutrient absorption and utilization is high, and it is not affected by the nutrient absorption center. It can meet or adjust the urgent needs of trees in the critical period of fertilizer. Overcome the defect of slow root absorption of nutrients, increase yield and quality. There is no soil fixation of nutrients compared to soil fertilization resulting in reduced availability and loss to soil leaching.

[0058] Root fertilization: When fertilizing the roots, the edge of the crown projection and a little far away should be the main area, so that...

Embodiment 3

[0066] The regulation of embodiment 3 different concentration reagents to fruit growth

[0067] ① Use the method of spraying leaves with different concentrations of reagents and blanks as controls, and observe and record the final maturity as follows;

[0068] ② The method of spraying leaves is compared with different concentrations of reagents and blanks, and observations are made every week and recorded as follows;

[0069] Table 3. The method of spraying leaves with different concentrations of reagents and blanks as controls. Comparison after maturity

[0070]

[0071] Table 4 uses the method of blade spraying to compare different concentrations of reagents and blanks as controls

[0072]

[0073] Experimental conclusion: For the same fruit tree, the spraying of different concentrations of reagents has different effects on fruit growth regulation. It can be seen from Table 3 and Table 4 that the effect of concentration 2 is stronger.

Abstract

The invention relates to a preparation method of a nanometer chitosamine-selenium preparation. The method comprises the steps of: dissolving sodium selenite in an ethanol solution of which the mass fraction is 75% to prepare a sodium selenite solution of which the mass fraction is 12.5%; weighing chitosamine and dissolving in distilled water to prepare a chitosamine solution of which the mass fraction is 8%; mixing 50ml of chitosamine solution with 40ml of sodium selenite solution, adding 10mg of surfactant and magnetically stirring for 30minutes; and carrying out pulsed ultrasound for 15minutes at a room temperature to obtain a chitosamine-selenium nanometer microsphere turbid liquid which is subjected to crosslinking and uniformly dispersion. The preparation method of a plant growth regulator chitosamine-selenium nanometer trace-element nutrition regulator is simple to operate, low in cost, easy in reaction control and high in product quality, and has no pollution; and the prepared nanometer preparation can be used for regulation of agricultural plant growth.

Description

technical field [0001] The invention relates to a chitosan-selenium nano-trace element nutritional regulator and its preparation. Background technique [0002] Chitosan is called by scientists as the sixth vital element after protein, fat, sugar, minerals and vitamins. It is an important nutrient necessary to enhance human health. [0003] [0004] Chitosan (CHITOSAN), scientific name (1.4)-2-amino-2-deoxy-β-D-glucan, is a polysaccharide composed of glucosamine and acetylglucosamine polymers, and the unit molecular formula of chitosan is C 6 h 11 NO 4 , The unit molecular weight is 161. Chitosan can be obtained by partial deacetylation of chitin in the carapace, and also exists naturally in some microorganisms and yeasts. The term chitosan refers to a series of chitosan polymers with different molecular weight (50kDa-2000kDa), viscosity and degree of deacetylation (40%-98%). Chitosan is insoluble in neutral and alkaline solutions, but forms salts with inorganic and...
