preparation example Construction
[0055] The present invention also provides a preparation method of the slow-release medicinal fertilizer, comprising: A) mixing and granulating the pesticide composition, fertilizer, auxiliary agent, slow-release material and filler to obtain the slow-release medicinal fertilizer.
[0056] The present invention has no special limitation on the sources of all raw materials, which can be commercially available. Wherein, the pesticide composition, fertilizer, adjuvant, slow-release material and filler are all the same as above, and will not be repeated here.
[0057] According to the present invention, it is preferable to first mix and granulate part of the pesticide composition, fertilizer and auxiliary agent, more preferably first to mix and granulate the amino oligosaccharin, humic acid, part of thiamethoxam, fertilizer and auxiliary agent in the agricultural chemical composition . The mixing is preferably carried out in a disc granulator. After the above-mentioned raw materi...
Embodiment 1
[0064] Mix thiamethoxam, amino oligosaccharides and humic acid for an indoor joint independent test experiment, use the nitrogen base of thiamethoxam, amino oligosaccharides and humic acid as the control agent, and mix the pesticide composition according to the following ratio 1~pesticide composition 5:
[0065] Pesticide composition 1: thiamethoxam: oligosaccharin: humic acid = 1:5:10;
[0066] Pesticide composition 2: thiamethoxam: amino oligosaccharin: humic acid = 1:2:10;
[0067] Pesticide composition 3: thiamethoxam: amino oligosaccharin: humic acid = 1:1:5;
[0068] Pesticide composition 4: thiamethoxam: amino oligosaccharin: humic acid = 5:8:10;
[0069] Pesticide composition 5: thiamethoxam: amino oligosaccharin: humic acid = 1:1:3.
[0070] In the experiment, wheat aphids were used as the test insects, and a blank control was set up. The single agent of thiamethoxam, amino-oligosaccharin and humic acid, and the above five pesticide compositions were used to soak i...
Embodiment 2
[0076] Pesticide composition: thiamethoxam 0.02%, amino oligosaccharin 0.1%, humic acid 0.2%;
[0077] Fertilizer: nitrogen content 20%, phosphorus content 15%, potassium content 10%, calcium content 0.1%, magnesium content 0.3%, zinc content 0.01%, boron content 0.01%, molybdenum content 0.01%;
[0078] Additives: stearic acid 1%;
[0079] Sustained release material: polyvinyl alcohol 1.5%;
[0080] Filler: supplemented to 100%, the filler is a mixture of attapulgite, bentonite and gelatinized starch.
[0081] According to the above ratio, put the amino oligosaccharidins, humic acid, fertilizer and additives into a disc granulator to pulverize, mix evenly, and the obtained mixture is the granule intermediate; Spray the pre-prepared 40% thiamethoxam oil suspension solution in the middle of the granules, and sprinkle the slow-release materials and fillers in the middle of the granules while spraying. After the granulation is completed, roll in the disc for 20 minutes, dry, cool...
