Embodiment 1

[0054] DPPA is used to prepare Huaguoling wettable powder, a plant growth regulator that promotes the production of melons and fruits.

[0055] A) Take ferrous sulfate: 8 parts, boric acid: 4 parts, magnesium sulfate: 15.75 parts, Baypure CX100: 5 parts, EDTA: 2 parts, stir evenly, and make chelated trace elements;

[0056] B) The rest, paclobutrazol: 7.5 parts, uniconazole: 3.75 parts, ethephon: 12.5 parts, penetrating adhesive type A: 2 parts, powder azone: 2 parts, YFK diffusing agent: 5 parts, DPPA: 2.5 parts, White carbon black: 30 parts, mixed evenly;

[0057] C) Mix A) and B) evenly.

[0058] The fractions of each component are weight fractions.

[0059] Apply the above-mentioned Guaguoling wettable powder product to actual agricultural production, and dilute it with water 600 times to form a suspension and spray it on the leaves and fruit surfaces. Increase production by 15-25%.

Embodiment 2

[0061] DPPA is used in the preparation of a plant growth promoter that promotes balanced growth - swelling and fast wettable powder.

[0062] A) Take zinc sulfate: 5 parts, boric acid: 5 parts, magnesium sulfate: 30 parts, Baypure CX 100: 1 part, EDTA: 1 part, stir evenly, and make chelated trace elements;

[0063] B) The rest, sodium 5-nitroguaiacol: 0.15 parts, sodium o-nitrophenolate: 0.3 parts, sodium p-nitrophenolate: 0.45 parts, fenfenzuron: 0.1 parts, sodium naphthalene acetate: 0.4 parts, ind Sodium indolebutyrate: 0.2 parts, adhesive union: 1 part, YFK diffusing agent: 8 parts, DPPA: 2 parts, white carbon black: 45.4 parts, mix well;

[0064] C) Mix A) and B) evenly.

[0065] The fractions of each component are weight fractions.

[0066] Apply the above-mentioned swollen and fast wettable powder product in actual agricultural production, dilute it with water 600 times to form a suspension and spray it on the leaf surface and fruit surface, which can overcome the sho...

Embodiment 3

[0069] DPPA, emulsifier and water are prepared together into an emulsion containing 10% DPPA, and 5 pieces of citrus leaves are directly soaked in the liquid. After 1 minute, the leaves are dull and the surface is rough.

Abstract

The invention provides the application of diphenyl phosphoryl azide (DPPA) in the aspect of treating the wax coat on the leaf surfaces of plants and the surface of fruit. The invention provides a new use of the DPPA; when the DPPA is used for treating the wax coat on the leaf surfaces of plants and the surface of fruit, the speed is rapid, and the effect is good; the leaves and the fruit are not damaged by the DPPA within a wider concentration range, and the wax coat on the leaf surfaces of plants and the surface of fruit can be effectively destroyed by the DPPA, so that the obstruction function of the wax coat on the leaf surfaces of plants and the surface of fruit for fertilization and other effective components can be greatly reduced, the absorption is improved, and the fertilizer and other effective components are better absorbed and utilized. Furthermore, a new raw material capable of bringing a remarkable effect is provided for the design of formula of a leaf fertilizer and a plant growth regulator used for the leaf surfaces. Furthermore, based on the research of the invention, a new processing reagent and an effective processing method are provided for smoothly, rapidly and completely removing the wax coat on the leaf surfaces when a leaf artwork is made.

Description

technical field [0001] The invention relates to a new application of DPPA (diphenylphosphoryl azide), in particular to the application of DPPA in treating waxy layers on plant leaves and fruit surfaces. Background technique [0002] There is a layer of wax on the plant leaves (including the front and back sides) and the fruit surface, which protects the leaves and fruits. But from the point of view of fertilization, this layer of wax plays a hindering role, reducing the utilization rate of fertilizer and affecting the efficiency of fertilizer. In terms of leaf stickers, leaf art paintings, leaf flower arrangements, etc., it is necessary to treat or remove the wax on the leaf surface in many occasions to facilitate subsequent processing such as coloring or gold-plating and silver-plating. [0003] Whether it is from the perspective of fertilization or the production of leaf artwork, a product that can quickly treat the wax on the surface of the leaf and fruit is required, an...
