Overwintering summer cucurbit adaptability, daytime temperature at 20 ~ 22 °C, night at 10 ~ 12 °C to normal growth. The old greenhouses have poor insulation properties, and the low temperature stage in winter is very suitable for the temperature requirements of zucchini. New greenhouses in the daytime canopy temperature above 30 °C, usually at 18 °C or more at night, the temperature is too high and not conducive to the growth of summer squash, resulting in reduced yield. Choosing good winter squash varieties is the basis for high yield and high efficiency. France Tezier company's Ferrari, Caesar, winter jade and other varieties of comprehensive traits, simple management, general acre production capacity of 15,000 kilograms or more, significant benefits.

The temperature was controlled at 18~20°C during the day and the temperature was controlled at 8~10°C during the night. Before sitting on the melon spray Amisite 250 g / l azoxystrobin suspension (1500 times liquid) plus copper noble 27.12% basic copper sulfate suspension (600 times liquid) to prevent disease.
