Exploring new models for reducing chemical fertilizer and pesticide use while increasing efficiency during the later stages of soil testing and formulated fertilization is a crucial pathway for developing high-quality,green crop farming.This study focused on potato cultivation in Xiaobaihu Town,Luliang County,Yunnan Province.A comparative experiment was conducted involving three treatments:conventional formula fertilization(CK),basal fertilizer application reduced by 30%combined with fullerene small-molecule active water treatment(CF30),and basal fertilizer application reduced by 50%combined with fullerene small-molecule active water treatment(CF50).The effects of these treatments on the potato growth period,agronomic traits,and yield were analyzed to evaluate the efficacy of fullerene small-molecule active water in reducing chemical fertilizer and pesticide use while increasing yield.Treatment with fullerene small-molecule active water advanced seedling emergence by two days,extended the growth period by three days,and promoted plant vigor.Under conditions of obvious reduction in both pesticide and fertilizer use,the treatment with a 30%reduction in basal chemical fertilizer combined with fullerene small-molecule active water(CF30)increased stem diameter by 9.1%compared to the conventional formula fertilization treatment(CK).Plant height and yield both increased,although the differences were not statistically significant.Moreover,the economic efficiency increased by 20.5%,and the marketable tuber percentage reached 91.21%,indicating excellent comprehensive performance.The treatment with a 50%reduction in basal chemical fertilizer combined with fullerene small-molecule active water(CF50)did not result in yield reduction,and the marketable tuber percentage remained close to 90%,with no significant differences among the three treatments.These results indicate that in the potato production of Luliang County,reducing chemical fertilizer application by more than 30%,reducing pesticide application by two-thirds,and using fullerene small-molecule active water as a substitute for pesticides can effectively balance the contradiction between"reducing pesticide and fertilizer use"and"increasing yield",thereby achieving green and high-quality potato production.Therefore,there is substantial potential for reducing fertilizer and pesticide use in the formulated fertilization model for potato production in Luliang County,Yunnan Province,and the use of fullerene small-molecule active water holds broad prospects for developing green production practices.
