In the general formula of the hydroxyxylamine derivatives (I), R 1 is unsubstituted or phenyl substituted on one or more of the halo genes or the clay diatomaceous earth, or N-heteroaryl, or pyloric acid, X is a halogen atom, an amine powder or hydrofluoric acid, Y is a hydrogel or hydrofluoric acid, or \ t if Y is a hydrofluoric acid coat, the copolymer comprises a primary XH elimination-forming dixazine ring terminating on the X-ray heat exchanger; together with my capped nitrogen gene, it forms a 5-7 stranded heterocycle. These compounds increase the cold and frost tolerance of the plants, as well as their drought tolerance, are non-toxic, non-toxic, and are suitable for the treatment of both adult plants and seedlings and seeds. ŕ |
