Based on experimental data and the same term meteoro- logical observation data, using the parallel observation method, the effect of temperature and ac- cumulated temperature above 10˚C and precipitation during the whole growth period of Cucumis metuliferus was analyzed. The results showed the lowest integrated temperature ≥ 10˚C for Cucu- mis metalliferous growth was 3300˚C∙d; the optimum temperature for seed germination, vegeta- tive growth and reproduction was 15˚C - 19˚C, 22˚C - 24˚C and 24˚C - 25˚C, respectively; the tem- perature below 20˚C was not suitable for the blossom. If the accumulated rainfall of 5 consecutive days was more than 50 mm and daily rainfall exceeded 5 mm for 4 consecutive days
