| Abstract: |
| 【Objectives】Explore the effect of selenium on sweet buckwheat growth and improve the yield and quality of sweet buckwheat.【Methods】The effects of 5 different concentrations of sodium selenium on sweet buckwheat growth were studied by random group potted plant experiments.【Results】Appropriate application of selenium fertilizer can promote the growth of sweet buckwheat. When the concentration of selenium fertilizer was 0-10mg/kg, chlorophyll synthesis, transpiration rate, stomatal conductance, net photosynthetic rate and biomass of sweet buckwheat could be promoted, and inhibition would be produced if the concentration exceeded 10mg/kg. From the whole growth period of sweet buckwheat, selenium fertilizer had the most significant effect on sweet buckwheat in the blooming period. In addition, proper application of selenium fertilizer can also slow down the decline of chlorophyll, transpiration rate, stomatal conductance and net photosynthetic rate in the growth process of sweet buckwheat, and delay the aging of sweet buckwheat.【Conclusions】Proper application of sodium selenite can promote the growth of buckwheat and delay the aging process. Excessive application of selenium fertilizer can inhibit the growth of sweet buckwheat, but not affect the root growth of sweet buckwheat |
