The authors in the countryside surveyed planting overwintering squash squash in the greenhouse, because the temperature is still high during the daytime shed, many vegetable farmers are still using hormones to control the growth of the squash, resulting in slow growth of squash, and some even appear hormonal poisoning. Because now has entered the winter, the temperature difference between day and night in the shed is relatively large, the vegetable farmers can not use hormones, but through the temperature control can effectively control the length of the zucchini. Grass drapes have been installed on the current sheds. After the straw drapes were all put down at night, the minimum temperature in the sheds was 16°C and the night temperatures were high, which led to the growth of the zucchini. In this way, the farmers can not put down the straw curtain when they are in the shed. Instead, they can control the temperature by putting the straw curtain on the two thirds or the front face of the greenhouse. The straw curtain can also be put down, but the shed is ventilated. The mouth should be properly opened and the night temperature in the shed should be controlled at about 12°C to reduce the consumption of nutrients. During the day, if the temperature in the booth is higher than 22°C, the ventilation temperature must be reduced to a maximum of 25°C. This can not only inhibit the growth of squash, but also promote their reproductive growth, thus effectively controlling the growth of the squash. For zucchini, which has already begun to produce melons, the vegetable grower can control the daytime temperature in the shed at 20°C~22°C and the nighttime temperature at 15°C to promote fruit development.
