Embodiment 1

[0031] A slow-release granule for preventing diseases and insect pests for citrus, which has a layered core-shell structure; includes a core layer, an isolation layer, an activated carbon layer and a gel layer from the inside to the outside; the core layer is filled with quicklime; the activated carbon layer It is filled with active carbon impregnated with EDTA; both the isolation layer and the gel layer are composed of hydrogel formed by chitosan cross-linking and polymerization.

[0032] The preparation method of the above-mentioned sustained-release granules is as follows:

[0033] 1) EDTA impregnation

[0034] After fully dissolving 5.2 parts of EDTA in excess deionized water, an EDTA-containing solution was obtained. Put 2 parts of activated carbon into the above solution and keep stirring at high speed for 15 minutes. After the stirring is completed, the water in the solution is evaporated under heating conditions. After the evaporation is complete, the activated carb...

Embodiment 2

[0042] A slow-release granule for preventing diseases and insect pests for citrus, which has a layered core-shell structure; includes a core layer, an isolation layer, an activated carbon layer and a gel layer from the inside to the outside; the core layer is filled with quicklime; the activated carbon layer It is filled with active carbon impregnated with EDTA; both the isolation layer and the gel layer are composed of hydrogel formed by chitosan cross-linking and polymerization.

[0043] The preparation method of the above-mentioned sustained-release granules is as follows:

[0044] 1) EDTA impregnation

[0045] After fully dissolving 5.7 parts of EDTA in excess deionized water, an EDTA-containing solution was obtained. Put 2.5 parts of activated carbon into the above solution and keep stirring at high speed for 18 minutes. After the stirring is completed, the water in the solution is evaporated under heating conditions. After the evaporation is complete, the activated ca...

Embodiment 3

[0053] A slow-release granule for preventing diseases and insect pests for citrus, which has a layered core-shell structure; includes a core layer, an activated carbon layer and a gel layer from the inside to the outside; the core layer is filled with quicklime; the activated carbon layer is filled with The activated carbon obtained by EDTA soaking treatment; the gel layer is composed of chitosan gel; a gel isolation layer is arranged between the core layer and the activated carbon layer; the gel isolation layer is composed of chitosan gel It is composed of glue; the gel layer is also wrapped with non-woven fabric.

[0054] The preparation method of the above-mentioned sustained-release granules is as follows:

[0055] 1) EDTA impregnation

[0056] After fully dissolving 5.2 parts of EDTA in excess deionized water, an EDTA-containing solution was obtained. Put 2 parts of activated carbon into the above solution and keep stirring at high speed for 15 minutes. After the stirr...

Abstract

The invention discloses a slow-release granule for preventing diseases and insect pests for citrus, which has a layered core-shell structure; has a layered core-shell structure; includes a core layer, an isolation layer, an activated carbon layer and a gel layer from the inside to the outside; the The core layer is filled with quicklime; the activated carbon layer is filled with activated carbon impregnated with EDTA; both the isolation layer and the gel layer are composed of hydrogel formed by chitosan cross-linking and polymerization. The slow-release granules designed through the core-shell structure not only effectively ensure the corresponding soil pest control effect of quicklime, but also significantly solve the problem of soil compaction caused by calcium ions and soil barrenness; the raw materials and their derivatives used are all It is non-toxic and harmless, and meets the requirements of green prevention and control of soil diseases and insect pests during citrus continuous cropping; the price of raw materials is low, it is convenient to use, and does not require post-treatment, and has significant economic benefits and promotion value.

Description

technical field [0001] The invention relates to the field of plant insect-repelling preparations, in particular to a slow-release granule for preventing diseases and insect pests for citrus. Background technique [0002] The history of citrus cultivation in my country has a history of more than 4,000 years, and after long-term cultivation and selection, citrus has become a precious fruit for human beings. As one of the important origins of citrus, my country has accumulated rich experience in the cultivation of citrus, and thus developed a set of mature citrus cultivation theory, and obtained a wide variety of high-quality citrus varieties. Continuous cropping, as a method of making full use of the climate and other natural resources of a place, and planting a large number of crops that are ecologically suitable and have high economic benefits, has become one of the important means of continuous cultivation of economic crops because of its full utilization of resources and s...
