Embodiment 1

[0029] A special nano-fertilizer for preventing sugarcane pests, the weight of each raw material: urea 13kg, monoammonium phosphate 8kg, potassium sulfate 9kg, commercially available nano-calcium carbonate 9kg, nano-carbon 8kg, nano-coating agent 1.2kg, zinc sulfate 3kg, manganese sulfate 3kg, chelated boron 3kg, Bacillus subtilis preparation 0.5kg, 22% fipronil granule 0.1kg, humic acid 42.2kg.

[0030] The nano-coating agent is made by mixing nano-bentonite and nano-carbon according to the mass ratio of 2:1, wherein the nano-bentonite is commercially available.

Embodiment 2

[0032] A nano-fertilizer specially used to control sugarcane pests. The weight of each raw material: 13 kg of urea, 8 kg of monoammonium phosphate, 9 kg of potassium sulfate, 9 kg of nano-calcium carbonate, 8 kg of nano-carbon, 1.2 kg of nano-coating agent, and 3 kg of zinc sulfate , manganese sulfate 3 kg, chelated boron 3 kg, Bacillus subtilis preparation 0.5 kg, 22% fipronil granules 0.1 kg, humic acid 42.2 kg.

[0033] The preparation method of nano calcium carbonate is as follows:

[0034] (1) Calcining calcium carbonate mineral powder at 1300°C for 2 hours to obtain white powder, cooling to room temperature, adding water to dissolve, obtaining calcium hydroxide suspension, injecting excess CO into the sealed tank 2 , to ensure the nucleation rate of calcium carbonate crystal nuclei, to obtain a homogenate; (2) add sodium polystyrene sulfonate with a mass of 2.0% of the homogenate to control the growth rate of each crystal plane, and carbonize the homogenate to a pH of 8....

Abstract

The invention discloses a special nano fertilizer for preventing and controlling sugarcane pests and a preparation method. The special nano fertilizer comprises the following components in percentageby mass: 24-35% of macro-element inorganic compound fertilizer, 8-10% of nano calcium carbonate, 4-10% of nano carbon, 1-3% of nano membrane envelope agent, 1-6% of zinc sulfate, 1-6% of manganese sulfate, 1-6% of chelated boron, 0.2-2% of bacillus subtilis preparation, 0.022-0.66% of fipronil and the balance of humic acid, wherein the total percentage is 100%. The nano carbon and nano calcium carbonate are added into the fertilizer at the same time; a dose of the nano membrane envelope agent is controlled; and due to a synergistic effect of the nano carbon, nano calcium carbonate and the nanomembrane envelope agent, the purposes of fast-acting, medium-acting and long-acting graded release of active ingredients of the medical fertilizer can be achieved.

Description

technical field [0001] The invention relates to the technical field of fertilizers, in particular to a nano-fertilizer specially used for preventing and controlling sugarcane pests and a preparation method. Background technique [0002] In recent years, sugarcane borers, thrips, cotton aphids, scale insects, sugarcane tortoises, termites and other pests have become important obstacles to sugarcane production, causing certain losses to sugarcane yield and quality, and the damage area of ​​ratoon cane is as high as 80%. Therefore, , sugarcane farmers will invest a lot of manpower and material resources every year to prevent and control. At present, highly toxic pesticides such as carbofuran, phorate, isofenphos-methyl and terbuthion are commonly used in production to control insect pests. Due to the long-term use of a single variety of pesticides, sugarcane pests in some areas have developed varying degrees of resistance to some pesticides. Drug properties. At present, the co...
