Four patterns of temperature and light regimes were adopted in the experiment to study effect of temperature and light on yield and quality of cucumber in energy-saving solar greenhouse.Treatments included A（daily average temperature 16℃,daily average light intensity 504μmol·m^-2·s^-1）,B（daily average temperature 19℃,daily average light intensity 385μmol·m^-2·s^-1）,C（daily average temperature 19℃,daily average light intensity 504μmol·m^-2·s^-1）,D（daily average temperature 16℃,daily average light intensity 385μmol·m^-2·s^-1）.The results indicated that C was the best according to yield,the single melon weight,the fruits length,fruits diameter,the pericarp thickness,the melon put length,the soluble sugar,the soluble solids content.The melon number per plant and the branch number per plant was the least in C.The single melon weight,the melon put length,the melon number per plant,the branch number per plant of C was significantly different from other treatments.
