1.Good UV protection effect of PVC fast roller shutter door
The UV-proof door curtain of PVC fast rolling door, as the screen of the welding welding area, can filter harmful UV rays through the scenery, which is convenient for viewing the working situation, and prevents the flying and diffusion of sparks, smoke, debris, etc., to protect the safety of personnel. prevent fire.
Sound insulation effect PVC fast roller shutter door curtain can reduce noise decibels, prevent noise diffusion, reduce noise pollution, and be used as a machine compartment screen to improve the sound insulation effect of operations.
2. Good cold resistance effect of PVC fast roller shutter door
In the case of low temperature, the PVC fast rolling shutter can still maintain a high degree of softness, making it convenient for people and vehicles to enter and exit, and has a good isolation effect. It can prevent the loss of air conditioning and heating to a greater extent and save energy.
3. Good airtight performance of PVC fast roller shutter doors
A sealing strip with better sealing performance is installed in the track of the fast roller shutter door. With the weight of the door curtain itself, it will not bend and affect the normal operation under the wind speed of the harsh weather.
4. Good thermal insulation and energy saving effect of PVC fast roller shutter doors
PVC fast rolling shutter not only consumes no electricity, has no noise, no moving components, improves freezing efficiency, but also reduces the number of revolutions of the freezer, saving up to 50% of electricity.
5. Good anti-static effect of PVC fast roller shutter door
The curtain of the PVC fast rolling door does not produce static electricity after friction, which is suitable for the factory effect where static electricity is strictly prohibited.
Widely used in office buildings, public buildings, hotels, hospitals, supermarkets and factories in Asia, Eastern Europe and Africa. The specific requirements of an effective door system in different situations (eg clean room, operating room) may vary in different parts of the world.

2. Cucumber fertilization technology to produce 1,000 kilograms of cucumber requires 2.6 kilograms of pure nitrogen, 1.5 kilograms of phosphorus pentoxide, 3.5 kilograms of potassium oxide, 4,000 kilograms of cucumber, 4000 kilograms of pure nitrogen, 10.4 to 13 kilograms of pure nitrogen, 6 to 15 kilograms of phosphorus pentoxide, and potassium oxide. 14 to 15.7 kilograms. In the early stage of fruiting, the first time dressing was applied. Mushi pure nitrogen was 3 to 4 kg and potassium oxide was 4 to 6 kg. In the early stage of the harvest, the first time, the topdressing melon was applied with 3 to 4 kg of pure nitrogen and 5 to 6 kg of potassium oxide. In the middle of the melon period, the third top-dressing, Mushi pure nitrogen 3 ~ 4 kg, potassium oxide 5 ~ 6 kg. Before planting, 5000 kg of organic fertilizer was applied to Mushi and 40-50 kg of phosphate fertilizer was applied.
3. Radish fertilization technology to produce 1,000 kilograms of radish requires 2.0 kilograms of pure nitrogen, 0.7 kilograms of phosphorus pentoxide and 2.9 kilograms of potassium oxide. 5000 kg of radish per mu requires 10 kg of pure nitrogen, 3.5 kg of phosphorus pentoxide, and 14.5 kg of potassium oxide. Before planting the radish, 2500 kilograms of organic manure and 25 kilograms of phosphorus fertilizer were planted. Into the rosette period, the first time dressing, Mushi pure nitrogen 5 kg, potassium oxide 7 kg. The first time the fleshy root was growing, the second fertilizer was applied, and 5 kg of pure nitrogen and 7 kg of potassium oxide were used.
4. Carrot fertilization technology to produce 1000 kilograms of carrots requires 2.4 kg of pure nitrogen, 0.8 kg of phosphorus pentoxide and 5.7 kg of potassium oxide. The production of carrots from 3000 to 4000 kg per mu requires 7.2 to 9.6 kg of pure nitrogen, 2.4 to 3.2 kg of phosphorus pentoxide, and 17.1 to 22.8 kg of potassium oxide. Before planting carrots, 2500 kilograms of organic manure and 25-30 kilograms of phosphate fertilizer were planted. Into the rosette period, the first time dressing, Mushi pure nitrogen 3 ~ 4 kg, potassium oxide 8 ~ 10 kg. During the root growth stage of the fleshy root, the second top dressing was applied. Mushi pure nitrogen was 4 to 5 kg and potassium oxide was 8 to 12 kg.
Main vegetable fertilization technology
1. Cabbage Fertilization Technology Production of 1,000 kilograms of cabbage requires 2.0 kg of pure nitrogen, 0.72 kg of phosphorus pentoxide, 2.2 kg of potassium oxide, 3,000 to 5,000 kg of cabbage per mu, and 6 to 10 kg of pure nitrogen and 2.2 to 3.6 kg of phosphorus pentoxide. Potassium oxide 6.6 to 11 kg. Before the planting of cabbage, 2500 kilograms of organic manure and 20-25 kilograms of phosphorus fertilizer were applied. Cabbage into the lotus stage for the first time dressing, Mushi pure nitrogen 36 kg, potassium oxide 3.3 to 5.5 kg. Into the cabbage ball stage, the second top dressing, Mushi pure nitrogen 3 ~ 6 kg, potassium oxide 3.3 ~ 5.5 kg.
