- 摘要：
Agents to influence plant growth contg reactive tensides, opt. other active components useful in the cultivation of crops and/or inert carriers or diluents. The tensides are prepd. in known ways using named amines: ethylene- or propylene-diamines and tri-amines, guanidine, dicyanodiamide, imidazole or substd. imidazolines; opt. together with urea. They are reacted with formaldehyde, acetaldehyde, or propionaldehyde and/or dihaloalkanes (2-6)C. The pref. water-sol. condensn. prods. have mol. wts. 15,000 and are completely- or partially alkylated with chains (1-12)C contg alkyl- or alkylcarboxylic acid amide end-gps. or complete- or partial salts with acids. The agents improve plant growth by increasing photosynthesis assimilation and nucleic acid content of plants. They act synergistically, are none-phytotixic and increase growth and yield of crops. The agents increase- and store water in the soil, improve its crumbly structure and the activity of soil bacteria.
