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.

Abstract

The invention discloses a disease and pest prevention slow release grain for an orange. The slow release grain is provided with a layered core-shell structure and comprises a core layer, an isolationlayer, an active carbon layer and a gel layer from inside out; the core layer is filled with quicklime; the active carbon layer is filled with active carbon immersed in EDTA; and the isolation layer and the gel layer are made of hydrogel prepared by cross-linking polymerization of chitosan. According to the slow release grain in a core-shell structure design, the quicklime effectively exerts a corresponding soil disease and pest control effect; the problem of soil hardening due to lack of calcium ions and soil depletion is significantly solved; raw materials used and derivatives of the raw materials are nontoxic and innocuous; the requirement of green soil disease and pest control during continuous orange cropping is met; the raw materials are low in price; and the grain is convenient to use, does not require post-treatment and has significant economic benefits and popularization 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...
