Embodiment 1

[0013] A preparation method for orange fruit thinner, comprising the following steps:

[0014] 1) Preparation of oligomeric chitosan: Add 25 parts of chitosan and 180 parts of deionized water into the reaction vessel, slowly raise the temperature to 65°C within 30 minutes under stirring conditions, and then add 85 parts of mass to the reaction vessel dropwise The fraction is 30% hydrogen peroxide, stop heating after constant temperature reaction for 3 hours, pour the reaction liquid into a beaker, let stand overnight and then filter, the filtrate is precipitated with 80% ethanol solution of 6 times its volume, and then filtered. The cake is washed twice with ethanol with a volume fraction of 95%, dried under vacuum at 56°C, crushed and sieved to obtain chitosan oligosaccharides; the preparation method of chitosan oligosaccharides is simple and easy to control, and its molecular weight is between 2800-3100 Not only the preparation cost is low and the output is high, but also th...

Embodiment 2

[0017] A preparation method for orange fruit thinner, comprising the following steps:

[0018] 1) Add 28 parts of chitosan and 200 parts of deionized water into the reaction vessel, and slowly raise the temperature to 68°C within 40 minutes under stirring conditions. At this time, 88 parts of hydrogen peroxide with a mass fraction of 32% are added dropwise to the reaction vessel. After 3.5 hours of constant temperature reaction, stop heating, pour the reaction solution into a beaker, let it stand overnight and then filter. The filtrate is precipitated with an ethanol solution with a volume fraction of 7 times its volume and is 90% and then filtered. The filter cake is filtered with a volume fraction of 99%. washed with ethanol for 3 times, vacuum-dried at 58°C, and then crushed and sieved to obtain chitosan oligosaccharide; 1.50 parts of 80% naphthalene acetic acid powder, 1.3 parts of dinitroformazan, 0.3 parts of 1-aminocyclopropane hydroxy acid, 0.12 parts of branched chain...

Embodiment 3

[0020] A preparation method for orange fruit thinning agent, comprising: preparing chitosan oligosaccharide, preparing fruit thinning agent, specifically comprising the following steps:

[0021] Preparation of oligomeric chitosan: 26 parts of chitosan and 185 parts of deionized water were added to the reaction vessel, and the temperature was slowly raised to 66° C. within 35 minutes under stirring conditions. At this time, 86 parts of mass fraction was added dropwise to the reaction vessel. 30% hydrogen peroxide, stop heating after constant temperature reaction for 3 hours, pour the reaction solution into a beaker, let stand overnight and then filter, the filtrate is precipitated with 88% ethanol solution of 6 times its volume and then filtered, the filter cake is used The volume fraction of 98% ethanol was washed three times, vacuum dried at 57°C, crushed and sieved to obtain chitosan oligosaccharide; the preparation method of chitosan oligosaccharide was simple and easy to co...

Abstract

The invention discloses a preparation method of an orange fruit thinning agent. The method comprises: preparation of oligochitosan and preparation of a fruit thinning agent. The specific steps include: firstly subjecting chitosan and deionized water to mixed reaction, then adding hydrogen peroxide, conducting ethanol precipitation and ethanol washing to obtain oligochitosan, adding naphthylaceticacid powder, dinitrocresol, 1-aminocyclopropanehydroxyl acid, branched secondary alcohol polyoxyethylene ether, trichlorfon, naphthylacetic acid, 6-benzyladenine, and a blending agent to obtain a fruit thinning agent stock solution, and conducting dilution to obtain the orange fruit thinning agent. The invention has the beneficial effects that: after spraying the fruit thinning agent to orange branches, a layer of fruit thinning agent film can be formed on the orange branches, the film can effectively inhibit the transpiration of branches and reduce the water loss of branches, the orange fruitthinning agent has powerful blossom and fruit thinning effects, has an insecticidal function at the same time of blossom and fruit thinning, in addition, the fruit thinning agent also can increase the single fruit weight, enhance the fruit shape index, increase the flower quantity of next year, and reduce fruit rust, and also has no influence on the orange storage quality.

Description

technical field [0001] The invention relates to the field of orange planting, in particular to a preparation method of an orange fruit thinner. technical background [0002] Flower thinning and fruit thinning is an essential cultivation technique measure in the production of fine fruit. Its main purpose is to improve fruit quality, reduce tree damage, reduce nutrient consumption, and improve tree resistance by preventing excessive fruiting. For some tree species or varieties, it can also effectively prevent the number of flower bud differentiation or non-differentiation flower buds caused by excessive fruiting, improve the quality of flower bud differentiation, thereby reducing or overcoming the size of the year. The main methods of flower and fruit thinning include artificial flower and fruit thinning, mechanical flower and fruit thinning and chemical flower and fruit thinning. Artificial flower and fruit thinning method is simple and effective, and is currently the most w...
