遮阳网覆盖蔬菜栽培的方式
The method of vegetable cultivation covered with shading net
1、温室遮阳网覆盖夏季在温室的玻璃屋面上覆盖遮阳网，如为连栋式温室，可在室内平挂遮阳网，多用于夏菜的延后栽培。例如，在温室中栽培的茄果类、瓜类、豆类蔬菜、在高温来临时覆盖黑色或银灰色遮阳网可防止植株早衰，延长开花结果期，提高产量，增进果实品质。甘蓝、菜花、芹菜、莴营、芥菜等秋菜需夏播育苗时，利用遮阳网覆盖，可以提高成苗率和秧苗素质。
1. Greenhouse shading net covering: In summer, the glass roof of the greenhouse is covered with a shading net. If it is a multi-span greenhouse, the shading net can be hung horizontally indoors, and is often used for delayed cultivation of summer vegetables. For example, eggplants, melons, and legumes cultivated in greenhouses, covered with black or silver gray shading nets during high temperatures, can prevent premature plant senescence, prolong the flowering and fruiting period, increase yield, and improve fruit quality. When autumn vegetables such as cabbage, cauliflower, celery, lettuce, and mustard need to be sown and raised in summer, using shading nets to cover them can improve the seedling rate and quality.
2、塑料大棚遮阳网覆盖夏季利用塑料大棚骨架或在塑料棚膜上覆盖遮阳网，网两边要离开地面1.6~1.8米，以利通风。棚膜与遮阳网并用，降温、防暴雨效果较好。还可以将遮阳网悬挂在大棚内距地面1.2~1.4米处，既有利通风，又不必每天揭盖，可用于大棚夏菜的延后栽培及秋菜育苗，也可用于夏伏天小白菜、菜心、伏莴笋、伏萝卜、伏芹菜、伏黄瓜、夏大白菜、生菜等的生产。
2. Plastic greenhouse shading net covering: In summer, use the plastic greenhouse skeleton or cover the shading net on the plastic greenhouse film. The two sides of the net should be 1.6-1.8 meters above the ground to facilitate ventilation. The greenhouse film and the sunshade net are used together, and the effect of cooling and rainstorm prevention is better. The shading net can also be hung in the greenhouse at a distance of 1.2-1.4 meters from the ground, which is conducive to ventilation and does not need to be uncovered every day. It can be used for delayed cultivation of summer vegetables in the greenhouse and seedling cultivation of autumn vegetables. It can also be used for the production of summer and summer Chinese cabbage, cauliflower, lettuce, radish, celery, cucumber, cabbage, lettuce, etc.
3、中、小拱棚遮阳网覆盖早春在塑料薄膜中、小棚上加盖遮阳网，可提早定植夏菜。夏秋季节利用中、小拱棚骨架作支架覆盖遮阳网，可以培育秋菜苗、栽培绿叶菜或在棚内提前定植秋菜。
3. Covering early spring with shading nets in plastic films or small arched sheds can help to plant summer vegetables in advance. During the summer and autumn seasons, using medium and small arched shed skeletons as supports to cover shading nets can cultivate autumn vegetable seedlings, cultivate green leafy vegetables, or plant autumn vegetables in advance in the shed.
4、小平棚遮阳网覆盖利用竹竿、木棍、铁丝等材料，在硅面上搭成平面或倾斜的棚架，棚架上面盖遮阳网。棚架宽约1.6米，高0.5~1.8米。低棚便于揭盖遮阳网;高棚便于在棚内操作;倾斜棚则兼有两者的优点。主要用于夏季绿叶菜栽培。
4. The small flat shed is covered with a sunshade net, which uses materials such as bamboo poles, wooden sticks, and iron wire to form a flat or inclined shed frame on a silicon surface. The shed frame is covered with a sunshade net. The scaffolding is approximately 1.6 meters wide and 0.5-1.8 meters high. The low shed is easy to uncover the shading net; High shed for easy operation within the shed; The sloping shed has both advantages. Mainly used for summer leafy vegetable cultivation.
5、遮阳网浮面覆盖又叫直接覆盖，飘浮覆盖，或哇面覆盖，是将遮阳网直接覆盖在哇面或植株上面的栽培方式。浮面覆盖可以在露地、中小棚或大棚中进行。
5. Sunshade net floating cover, also known as direct cover, floating cover, or Wamian cover, is a cultivation method that directly covers Wamian or plants with a sunshade net. Floating surface coverage can be carried out in open fields, small and medium-sized sheds, or greenhouses.
主要用于蔬菜出苗期覆盖。如夏季栽培绿叶菜，播种后用遮阳网覆盖畦面，隔一定距离将网压住，以防风吹，可遮光、降温、保湿，为种子发芽和出苗创造有利条件。出苗后将遮阳网揭除，就地用竹片搭成小拱棚或小平棚，将遮阳网移到棚架上型槽模具 一次性止血带 保定水处理设备 一次性止血带 保定空压机 北京真空泵。此外，在越冬蔬菜越冬期间及春甘蓝、春花椰菜、春大白菜等春季定植后一段时间，采用遮阳网浮面覆盖有保温效果。
Mainly used for covering vegetable seedlings during their emergence period. For example, when cultivating green leafy vegetables in summer, cover the border surface with a shading net after sowing, and press the net down at a certain distance to prevent wind blowing. It can block light, cool down, and moisturize, creating favorable conditions for seed germination and emergence. After emergence, remove the shading net and build a small arched or flat shed with bamboo sheets on site. Move the shading net to the shed frame. In addition, during the overwintering period of overwintering vegetables and for a period of time after spring planting, such as spring cabbage, spring cauliflower, and spring Chinese cabbage, using a shading net floating surface cover has a thermal insulation effect.
