[0001] This utility model relates to the field of watermelon pest and disease prevention cultivation, and in particular to a watermelon pest and disease prevention cultivation cover. Background Technology

[0002] Currently, Chinese patent CN221329701U discloses a seedling rack for watermelon cultivation greenhouses, including a seedling rack body. The seedling rack body is fixedly connected to a shelf by several connecting rods. Rollers are fixedly connected to the bottom of the shelf at the bottom. The seedling rack body is covered with an insect-proof cover. A door is opened on one side of the insect-proof cover. Several through holes are opened on both the insect-proof cover and the door. This utility model, by covering the seedling rack with an insect-proof cover, can not only prevent watermelon seedlings from being damaged by insects and reduce the amount of pesticides used for pest control, but also provide appropriate shading to avoid damage to the seedlings caused by direct sunlight, while not affecting ventilation.

[0003] Watermelon pest and disease prevention cultivation covers are protective facilities specifically designed for watermelon cultivation. These covers are placed above and around the watermelon plants, creating a relatively independent microenvironment. The aim is to effectively block external pests such as aphids, thrips, and fruit flies from harming the watermelon plants through physical isolation. However, most existing watermelon pest and disease prevention cultivation covers lack reinforced limiting structures, making them susceptible to damage from strong winds and other adverse weather conditions, significantly reducing their protective effect. Furthermore, their pest control methods are limited, leading to frequent outbreaks of pests and diseases, seriously threatening the health of the watermelon plants. Temperature and humidity are also difficult to control, and poor ventilation can result in excessively high or low temperatures and humidity, which is detrimental to watermelon growth and increases planting risks. In addition, they are not convenient for adjusting the space according to the watermelon's growth stage, restricting the plant's growth space and hindering its normal growth. Utility Model Content
