[0029] Synergist configuration 1000g

[0030] Get 50g carboxamide and dissolve in 924g deionized water to make nitrogen-containing solution; Add 5g nano-carbon black with a particle diameter of 40nm, 6g fatty acid salt and 10g sodium octylphenol polyoxyethylene ether sulfate in nitrogen-containing solution, and use high-speed Stir and mix it evenly with a shear mixer at 3000-4000 rpm; heat the mixed solution under stirring conditions, raise the temperature to 45°C, and stir for 20 minutes; cool the stirred solution to room temperature to obtain a semi-finished product of nanofluid; Add 5g of chitosan to the semi-finished product, and vibrate ultrasonically for 20 minutes to obtain the finished product—nano pesticide and fertilizer synergist, with a pH of 9. In the urea production process, the urea product added with the above-mentioned synergist can still achieve the effect of increasing the yield by 8% if the amount of the urea product is reduced by 30% and applied to wheat t...

[0032] Synergist configuration 1000g

[0033] Dissolve 210g of ammonium polyphosphate in 714g of deionized water to make a nitrogenous solution; add 5g of nano-carbon black with a particle size of 30nm, 20g of metal soap and 50g of alkyl glycosides to the nitrogenous solution, and use a high-speed shear mixer at 3600-4000 RPM to stir and mix it evenly; heat the mixed solution under stirring condition, raise the temperature to 45°C, and stir for 20 minutes; cool the stirred solution to room temperature to obtain a semi-finished product of nanofluid; add 1g of nitrogen to the semi-finished product Ketone, through ultrasonic vibration for 20 minutes to obtain the finished product—nano-pesticide and fertilizer synergist, with a pH value of 9. Adding 1% of this synergist when glyphosate is applied can increase the herbicidal effect by 40% (shortened in time).

[0035] Synergist configuration 1000g

[0036] Get 100g ammoniacal liquor and dissolve in 874g deionized water and make nitrogenous solution, add the nano-carbon black of 5g particle diameter 40nm in nitrogenous solution, 6g fatty acid salt and 10g sodium octylphenol polyoxyethylene ether sulfate, use high-speed shear Cut the mixer at 3000 to 4000 rpm to stir and mix it evenly; heat the mixed solution under stirring conditions, raise the temperature to 45°C, and stir for 20 minutes; cool the stirred solution to room temperature to obtain a semi-finished product of nanofluid; Add 5g of chitosan to the semi-finished product, and vibrate ultrasonically for 20 minutes to obtain the finished product—nano pesticide and fertilizer synergist, with a pH value of 9. In the process of compound fertilizer production, the compound fertilizer product after spraying the above-mentioned synergist can still achieve the effect of increasing rice yield by 13.7%.

Abstract

The invention provides a nano-fertilizer pesticide synergist. The nano-fertilizer pesticide synergist comprises the following ingredients, by weight, 5-21% of soluble nitrogen-containing substances, 0.5-5% of dispersants, 0.5-5% of surfactants, 0.1-1% of penetrants, and 0.05-0.5% of nano-carbon black, the balance being deionized water. The invention provides a preparation method for the nano-fertilizer pesticide synergist. Nanoparticles in the prepared nano-fluid are small in particle sizes, the distribution scope is narrow, the dispersity is good, there is no agglomeration, and therefore the stability of the obtained nano-fluid is good. The preparation method has characteristics of simple devices and technologies, mild conditions, high raw material utilization rate, low cost, easy industrialization and the like.

Description

technical field [0001] The invention belongs to the technical field of fertilizers, and in particular relates to a nanometer chemical fertilizer and pesticide synergist and a preparation method thereof. Background technique [0002] Fertilizer is an important means of production in agriculture and plays an irreplaceable role in ensuring food security, but at the same time, fertilizer is also a strategic material with high energy consumption and scarce resources. At present, the fertilizer loss rate is high and the economic loss is huge. The fertilizer effect period of fertilizer is short, it is difficult to meet the fertilizer requirements of crops throughout the growth period, and the loss rate of fertilizer is high. Moreover, a large amount of fertilization will cause serious environmental pollution. Due to the eutrophication of surface water, lake pollution, groundwater pollution and other problems caused by excessive fertilization, social health problems such as seriou...
