When covering the sunshade net, the management of the sunshade net should be strengthened according to weather changes and different stages of celery growth.

They have the characteristics of strong tensile strength, aging resistance, corrosion resistance, radiation resistance, and lightweight.

At noon, the humidity increase is the highest, generally reaching 13-17%. With high humidity, soil evaporation decreases, increasing soil moisture.

After covering the sunshade net, due to its cooling and windproof effect, the communication speed between the covered area and the outside world is reduced, which significantly further increases the relative humidity of the air.

Mainly used for the protective cultivation of vegetables, fragrant mushrooms, flowers, edible fungi, seedlings, medicinal herbs, ginseng, Ganoderma lucidum and other crops, as well as aquaculture and poultry farming, it has a significant effect on increasing yield.

Sunshade net, also known as shading net, is a new type of protective covering material specifically designed for agriculture, fishing, animal husbandry, windproof, and soil covering.

Another method is to cover the eggplants, melons, and legumes planted in early spring at night to prevent frost.

Short term coverage after planting, one is to cover cabbage, cauliflower, Chinese cabbage, celery, lettuce, etc. planted in summer and autumn until they survive, covering them day and night, and directly covering the crops;

The method is usually to cover it directly on the ground, but the net should be removed in a timely manner after emergence to avoid hindering the growth of seedlings.

The main purpose of covering after sowing is to maintain soil moisture and prevent soil hardening after rainstorm.

Covered inside the greenhouse, usually not covered at a height of 1-1.5 meters from the ground.

Covering around the perimeter of the shed, commonly used for insulation at night in early spring.

Celery should be covered with a net all day before emergence, and after emergence, the net should be opened at both ends in the morning and evening to see light.

When the sunlight is strong at noon, the net should be covered. It can be left uncovered all day in cloudy days, but the net must be covered in time before rainstorm.

When single mesh and mesh are combined for coverage, the sides of the greenhouse are generally suspended about 1 meter above the ground and not covered.

Greenhouse cover, which can be divided into single net cover, mesh combined cover, outer perimeter cover, and inner greenhouse cover.

It belongs to a new type of weed control method that replaces the original manual and herbicide weed control.

The principle of weed control is to block the photosynthesis of weeds through shading, thus achieving the purpose of weed control.
