1. When covering the sun shade network, the management of sunshade network should be strengthened according to the changing weather and different periods of celery growth. The celery should be covered all day before the seedling, after the seedling should be exposed to the light in the morning and evening, when the sun is strong on the cover. If you encounter a cloudy day, you can cover it all day long, but make sure to cover it in time before the rain falls.
2. The width of the shading network can be cut and spliced arbitrarily. The method of cutting is to use the heating wire to cut off, because of the high heat of the sun screen can be fused into a way, not loose. The method of splicing is to sew with nylon thread on sewing machine or by hand, avoid binding ligation with wire or aluminum wire, so as to avoid mechanical fracture, and affect the service life of sunshade net.
3. The floating surface covers the sunshade net directly on the ground or on the plant, usually after planting and planting.
4. small tunnel coverage The sun-shade net cover on the film of small tunnel arch, suitable for summer fall shading, cooling, ventilation, or early spring night, frost prevention, can also be used for the monsoon rain or winter and heat preservation at night.
5. The flat cover is covered with a plane or inclined bracket of 0.5 ~ 1.8m high on the finished ceiling, and covers the shading net on the bracket for shading and rainproof.
6. The canopy covers the covering of the large canopy, covering the network, covering the retina, covering the outer cover and covering the canopy. When the single net and the omentum are combined, the two sides of the canopy are suspended from the ground about 1 meter. The outside of the shed is covered and used for early spring night heat preservation. Canopy cover, generally 1 ~ 1.5 meters away from the ground.
7. The main purpose of covering after sowing is to keep the soil moisture and prevent the soil after rainstorm. Prevent insects and birds from harm. The method is usually directly covered on the ground, but after the seedling, the net should be exposed in time, so as not to hinder the growth of seedlings. 2. Plant after short-term cover, one is for summer and fall after engraftment of cabbage, cauliflower, Chinese cabbage, celery, lettuce, etc to coverage, until cover to survival, day night jie, can cover directly on the crops; The other is to protect the early spring from the early spring of the jacket, melon beans cover to prevent frost.
