覆盖遮阳网时，应根据天气变化情况，芹菜生长的不同时期，加强遮阳网的管理。芹菜出苗前应全天盖网，出苗后应当早晚两头揭网见光，中午阳光强烈时盖上。遇到阴天可全天不盖，但暴雨来临前一定要及时盖网。
When covering the shading net, the management of the shading net should be strengthened according to weather changes and different stages of celery growth. Before celery sprouts, it should be covered with a net all day. After sprouting, the net should be lifted at both ends in the morning and evening to see light, and covered when the sunlight is strong at noon. It can be left uncovered all day in cloudy days, but the net must be covered in time before rainstorm.
二、遮阳网使用宽度可任意切割和拼接。切割的方法是用电热丝高热切断，因遮阳网高热切断后能熔结成道，不致松散。拼接的方法是用尼龙线在缝纫机上或用手工缝制，切忌用铁丝或铝丝捆绑结扎，以免造成机械断裂，而影响遮阳网的使用寿命。
2、 The width of the shading net can be cut and spliced arbitrarily. The cutting method is to use electric heating wire for high heat cutting, as the sunshade net can melt and form a path after high heat cutting, which will not loosen. The method of splicing is to use nylon thread on the sewing machine or sew by hand. It is important to avoid tying with iron or aluminum wire to avoid mechanical breakage and affecting the service life of the sunshade net.
三、浮面覆盖 将遮阳网直接盖在地面或植株上，一般在播种时、定植后。
3、 Floating surface covering directly covers the shading net on the ground or plants, usually during sowing and after planting.
四、小拱棚覆盖 将遮阳网覆盖在薄膜小拱棚的拱形支架上，适于夏秋季遮光、降温、透气或早春夜间防霜使用，也可用于雨季防雨或冬春夜间保温。
4、 The small arched shed covers the shading net on the arched support of the thin film small arched shed, which is suitable for shading, cooling, breathability in summer and autumn, or frost prevention in early spring and night. It can also be used for rain prevention in the rainy season or insulation in winter and spring at night.
五、平棚覆盖 在做好的棚面上搭成0.5～1.8米高的平面或倾斜的支架，把遮阳网盖在支架上，用于遮阴和防雨。
5、 The flat shed is covered with a 0.5 to 1.8 meter high flat or inclined support on the prepared shed surface, and the shading net is covered on the support for shading and rain prevention.
六、大棚覆盖 大棚覆盖又分单网覆盖、网膜结合覆盖、棚外四周覆盖及大棚内覆盖等。单网和网膜结合覆盖时，大棚两侧离地1米左右一般悬空不覆盖。棚外四周覆盖，多用于早春夜间保温。大棚内覆盖，一般离地1～1.5米不盖。
6、 Greenhouse coverage can be divided into single net coverage, net film combined coverage, outer and outer perimeter coverage, and inner greenhouse coverage. When a single net and a mesh are combined for coverage, the two sides of the greenhouse are generally suspended about 1 meter above the ground and not covered. Covering around the outside of the shed, it is often used for insulation in early spring and at night. Covering inside the greenhouse, usually 1-1.5 meters above the ground without covering.
