The Privacy Smart Film can be controlled in two sections up and down, transparent, atomized, shutter, and one-button free switching. No matter what kind of louver effect the glass is transformed into, it is difficult to see the cutting marks on the edge of the louver with the naked eye to ensure the visual beauty. Realize the transparency or atomization of different areas of glass, and can be freely designed. Glass can be fully transparent, fully atomized and louver effect, corresponding to open, private and semi-private space state, one key to change the state, easily realize the switch of space function and use.
Dimming projection has more advantages in cost and energy saving. LED screens installed on popular buildings will block Windows and affect the use of space in the building itself, and it is expensive. Dimming projection on the cost will be much lower, only a projector with a projection display task can be completed. In addition, dimming projection in the use of energy saving characteristics, can be called a model of environmental protection.

According to the fertilizer requirement of pepper and the fertility of soil, the fertilization of greenhouse pepper is based on heavy application of fertilizer and topdressing. The specific principles of fertilization should be as follows:
1. Re-apply organic fertilizer. Apply some decomposed organic fertilizer (such as chicken manure). In the old greenhouse, some enzyme bio-organic fertilizers can be added. For the greenhouses with serious soil-borne diseases (especially dead trees), some Bacillus bio-organic fertilizers should be added.
2. Reasonable use of chemical fertilizers. When using fertilizer as a base fertilizer, try to use simple fertilizers such as urea, superphosphate, and potassium sulfate. When applying compound fertilizer, try to use nitrate-containing compound fertilizer. In the seedling, transplanting and planting period, the true roots are applied, the rooting is fast, and the roots are many, which can shorten the time of pepper slowing and increase the resistance of the seedlings to the bad environment. The ability of peppers to continuously sit fruit, less flowering, high yield, and improved quality.
3. Reasonably allocate the proportion of base fertilizer and top dressing. Under normal circumstances, organic fertilizer, micro-fertilizer, 80% of phosphate fertilizer, 50% of potassium fertilizer and 30% of nitrogen fertilizer are mixed to make base fertilizer, and the remaining 70% of nitrogen fertilizer, 20% of phosphate fertilizer and 50% of potassium fertilizer are used for top dressing. For some trace elements such as borax, it can be sprayed on the surface.
The pepper has a long growing period, but the root system is not developed, the root amount is small, the soil is shallow, the drought is not resistant to drought, and the fertilizer resistance is strong. Pepper is a type of vegetable with a large amount of fertilizer. For every 1000 kilograms produced, it requires about 5.19 kilograms of nitrogen, 1.07 kilograms of phosphorus pentoxide, and 6.46 kilograms of potassium oxide. In different growth stages, the amount of nutrients such as nitrogen, phosphorus and potassium absorbed is also different. From the emergence to the bud, the initial flowering stage, the flowering stage and the mature stage, the amount of fertilizer absorbed accounts for 5% of the total fertilizer requirement. 11%, 34% and 50%, the results from the initial flower to the full bloom are the period of vegetative growth and reproductive growth of pepper, and also the period of absorption of nutrients and nitrogen. From the flowering to the maturity, the vegetative growth of the plant is weak. Phosphorus and potassium are most needed; after harvesting of mature fruit, in order to promote the growth and development of branches and leaves in time, a large amount of nitrogen fertilizer is needed.
