Embodiment 1

[0018] The selection of acidic solvent in the microemulsion of embodiment 1

[0019] Dissolve 10g of citric acid and 10g of boric acid in advance. Dissolve 11 parts of 4.5g chitosan in 10g of different acids or acid solutions, dissolve 0.05g of forchlorfenuron in 10g of ethanol, mix well with the chitosan solution, and then add polyoxyethylene alkyl aryl ether 10 g, the above mixture was stirred in a stirrer, and water was added to 100 g to obtain 4.55% chitosan·forchlorfenuron microemulsion, and the 11 preparations were respectively numbered as preparation 1-preparation 11.

[0020] (1) Dilute formulations 1-11 with 342 mg / L standard hard water, and observe the stability of the emulsion. A preparation that maintains a transparent state without oil suspension or solid precipitation is evaluated as stable.

[0021] (2) Select the stable preparation measured in the test (1), take the sample, seal it, refrigerate at 2-3°C for 24 hours, take it out, place it at room temperature,...

Embodiment 2

[0026] Example 2 4.55% chitosan forchlorfenuron microemulsion

[0027] Dissolve 4.5g of chitosan with 10g of lactic acid, fully dissolve 0.05g of forchlorfenuron with 10g of ethanol, mix the above solution, add 5g of polyoxyethylene oleyl ether, stir the mixture in a stirrer, and make up with water to 100g to obtain 4.55% chitosan·forchlorfenuron microemulsion.

Embodiment 3

[0028] Example 3 4% chitosan · forchlorfenuron aqueous solution

[0029] Dissolve 3.98 g of chitosan with 10 g of lactic acid, and dissolve 0.02 g of forchlorfenuron with 2 g of ethanol. After mixing the above solutions, add 2 g of polyoxyethylene oleyl ether, stir, and make up to 100 g with water to obtain 4% chitosan Sugar · forchlorfenuron aqueous solution.

Abstract

The invention belongs to the agricultural field, and relates to a composition containing chitosan and forchlorfenuron. The mass part ratio of the chitosan to the forchlorfenuron is 8:1-199:1, the composition further contains acidic substances and a surfactant and can be prepared into microemulsion, an aqueous solution, a suspending agent, emulsion in water, wettable powder and water dispersible granules, the composition is diluted by 500-5,000 times to be applied to spray or soak all parts or partial parts of crop plants, the crop setting percentage and the single fruit weight are increased, fresh keeping is achieved, and the quality is improved.

Description

technical field [0001] The invention relates to a plant growth regulating substance, in particular to a quality-stable composition containing chitosan and forchlorfenuron and its application. Background technique [0002] It is estimated that chitin (chitin, chitin, chitin) produced in nature is the biological polymer with the largest reserves next to cellulose, and it has more functional properties than cellulose cord. It is widely Found in fungal cell walls, nematode microfibrous sheaths, arthropod exoskeletons and the gut lining of many insects. In 1811, French scientists extracted a cellulose-like substance from mushrooms and named it chitin. Later, after heating chitin in NaOH, a new substance, chitosan, was obtained. . Chitosan (chitosan), chemical name (1,4)-2-amino-2-deoxy-β-D-glucan, is a water-soluble product of chitin deacetylated by concentrated alkaline water , the molecular weight is usually above 5000. Due to the poor solubility of chitin, its application ...
