Problems solved by technology

The above-mentioned drought-resistant seed coating agents are all of the compound type of medicine and fertilizer, the content of polymer water-absorbing agent is small, and the water-absorbing ability is weak.
In addition, the fungicides in the drought-resistant seed coating agent disclosed above are highly toxic pesticides such as carbofuran, methamidophos, and isofenphos-methyl. These pesticides pollute the environment and have been banned from being used on vegetables and fruit trees. control use
The polymer water-absorbing agents in the "plant drought-resistant agent composition" disclosed in CN1077771C are mainly PAM, PAA and SPA, the cost is relatively high, and the main components are water-absorbing agents and nutrients, the components are relatively single, and the effect is not ideal
The polymer water-absorbing agent disclosed in CN1426685A in the "preparation method of seed coating agent for dry farming" is obtained by the copolymerization and cross-linking reaction of two monomers, acrylamide and sodium acrylate, through ionizing radiation, and the processing cost is relatively high. The preparation process is more complicated
