Embodiment 1
[0025] An alkaloid-containing humic acid insect-proof and antibacterial organic silicon fertilizer, comprising 100 parts of ammonium humate, 10 parts of sodium silicate, and 10 parts of coptis alkaloids, in parts by mass, the specific preparation method is as follows:
[0026] 1) Wash, dry and pulverize Coptis rhizome, add it to an ultrasonic mixer, and stir it with ethanol at a solid-to-liquid ratio of 1:15 for 30 minutes, then transfer the resulting mixed solution to the reflux device, and the reflux is not less than 4, and the reflux time for each time After not less than 1.5h, combine the reflux liquid, then concentrate the reflux liquid under reduced pressure, freeze-dry to obtain the crude alkaloid; 3:1 eluent of methanol and water was used to elute, the sample solution was collected and then dried, then dissolved in 90% methanol solution after drying, recrystallized, filtered and dried to obtain Coptis rhizome alkaloids;
[0027] 2) In terms of parts by mass, 100 parts ...
Embodiment 2
[0032] An alkaloid-containing humic acid insect-proof and antibacterial organic silicon fertilizer, comprising 100 parts of potassium humate, 15 parts of calcium silicate, and 5 parts of deer tail alkaloid, in terms of parts by mass, and its specific preparation method is as follows:
[0033] 1) Wash, dry, and pulverize clover grass, then add it to an ultrasonic mixer, and stir it with ethanol at a solid-to-liquid ratio of 1:10 for 30 minutes, transfer the resulting mixed solution to a reflux device, and reflux no less than 4 times, each The refluxing time is not less than 1.5h, the reflux liquid is combined, and then the reflux liquid is concentrated under reduced pressure, and the crude alkaloid can be obtained after freeze-drying; the crude alkaloid is dissolved in methanol solution and filtered, and the filtrate is subjected to silica gel column chromatography, and then used The eluent of methanol and water with a volume ratio of 3:1 is eluted, the sample liquid is collecte...
