Description
Technical Field
The invention relates to an ecological nano suspension capable of promoting crop yield increase and improving the value of crops, which can be widely applied to the field of crop planting of vegetables, fruits and the like.
Technical Field
Nanotechnology has been rapidly developed in recent years, and nanoparticles have unique characteristics such as small size effect and surface effect, so that the nanoparticles exhibit many excellent properties and completely new functions. Nanotechnology, including the technology of suspending nanoparticles in solution for a long time, has been the focus of research at home and abroad. There are still some problems with current nanotechnology, especially nanoparticle suspension technology: (1) most of the nano suspending agents use organic solvents during preparation, the final nano water suspending agent also contains organic solvents, and some organic solvents cause pollution to the environment during use; (2) some nano suspending agents have high energy consumption, high cost and high difficulty in preparation, cannot realize industrial production, and bring difficulty to the application of nano water suspending agents. (3) The time for suspending the nanoparticles in the nanoparticle suspension is not long, and some nanoparticles in the suspension begin to settle after a few minutes.
Nevertheless, the scholars at home and abroad still do in-depth screening and trial, and the commonly tried nanoparticle suspending agents include sodium dodecyl sulfate, sodium alkyl sulfonate, polyacrylic acid (PAA), polyvinyl alcohol (PVA), carboxymethyl cellulose (CMC), sodium carboxymethyl cellulose, chitosan and the like, which can effectively prevent the aggregation and sedimentation of nanoparticles in a short time, but the nanoparticle sedimentation phenomenon occurs after a long time (even after a few minutes). Patent CN105854847A discloses a preparation method and application of a starch modified nano zero-valent iron suspension material, wherein sodium carboxymethyl starch is used as a dispersing agent, although the sodium carboxymethyl starch has a certain dispersing effect, the durability is poor, and nano iron is easy to deposit in water. Patent CN 1389520A discloses a multifunctional nano zinc oxide suspension and a preparation method thereof, which uses polymer (polyacrylate, polyvinyl alcohol, silicone oil) as a dispersed phase to suspend in organic solvent, and has a good dispersing effect, but also has a problem of short suspension time of nanoparticles. Patent CN105001433B discloses a preparation method and application of chitosan nanoparticle suspension, the preparation method comprises the steps of firstly dissolving chitosan in glacial acetic acid aqueous solution to prepare chitosan acetic acid aqueous solution, then dropwise adding sodium tripolyphosphate aqueous solution under the stirring condition to obtain chitosan nanometer coarse suspension, filtering the chitosan nanometer coarse suspension, and then carrying out high-pressure homogenization treatment to obtain the nanometer chitosan suspension with uniform particle size distribution. The patent technology uses an organic solvent, not only is the preparation method complicated, but also the time for suspending the nano particles in the organic solvent is limited.
Disclosure of Invention
The suspension containing the three nano-particles of iron, titanium and selenium is convenient to use and has important significance in promoting healthy and strong growth of plants, improving the value and quality of agricultural products and the like. The invention discloses an ecological nano suspension which can promote the crop yield increase (for example, the rice yield increase is more than 15 percent, and the cabbage yield increase is more than 16 percent) and improve the value of the ecological nano suspension. The suspension is non-toxic and harmless, does not contain organic solvent, can stably suspend all nano particles for more than 20 days, has simple preparation process and low cost, is green and environment-friendly in the whole preparation process, and does not generate three wastes.
