A shade arch shed was built in the field. The height of both sides of the arch shed should be higher than 25cm from the nursery bed and above 45cm in the middle. After covering the colorless plastic film, it is covered with about 65% sunshade net, and the edge is compacted to prevent air leakage and ventilation. When the temperature in the shed reaches or exceeds 40 ℃ during the day, remove the film at both ends or in the middle to reduce the temperature to prevent the seedlings from being burned by high temperature; do a good job of heat preservation and moisture preservation by compacting the edge of the shed in winter.
Strength description: please wear hiking shoes or travel shoes, do not wear leather shoes, high heels, backpacks, sunshade hats, the route is about 8 kilometers, rising and falling are about 400 meters. Enjoy the lace and play, have a picnic after enough, there is no danger in the route, just be careful, please listen to the arrangement of the team leader to ensure safety.
As we all know, temperature is the basic condition to ensure the normal growth of crops. Greenhouse is a thermal insulation agricultural facility for the normal and rapid growth of crops. Heat preservation is an important work in greenhouse agricultural production, so suitable covering materials must be selected. Generally speaking, glass greenhouse is better than glass greenhouse, glass greenhouse can play a decorative role in appearance, and the aging and damage problems of glass greenhouse can be relatively small compared with plastic greenhouse; in terms of performance, due to the complexity of the environment, glass greenhouse can resist various loads (wind load, snow load, etc.). Aluminum alloy (or stainless steel) + plexiglass, ordinary glass, low-cost bamboo ponds and plastic films with beautiful and durable, windproof, rainproof, sunscreen, heat preservation effect and cost, can also be equipped with sunshade and sprinkler system. Plants usually need plenty of light and better glass. Of course, the one-time investment cost of plastics is lower, but the later maintenance cost is also higher, and plastics are easy to age.
The heat preservation of the greenhouse is very high in summer, so all the vents around the vegetable greenhouse must be opened. If the temperature is too high, the top of the vegetable greenhouse can be covered with sunshade net to cool down. In the sunny day, the temperature in the shed should be measured in time. As soon as the temperature rises to more than 30 ℃, open the ventilation vents on both sides and adjust the vents to stabilize the temperature in the shed at 25 ℃-30 ℃ as far as possible. Take light enhancement measures to increase light intensity and prolong light time; select agricultural film with high light transmittance and wipe it frequently to ensure that the surface of agricultural film is clean; cover white plastic film; hang reflective curtain on the back wall; prune and pick leaves in time to enhance the light transmittance of the field.
PC sunlight board integrates daylighting, thermal insulation and sound insulation, which can be used for greenhouse, furniture canopy, office sound insulation, outdoor advertising light box and so on. In terms of greenhouse construction, there are greenhouses built with sunboards, gables and sidewalls using sunboards; in terms of greenhouse efficacy, there are production-based greenhouses, trade greenhouses dominated by flower trading centers, and greenhouses dominated by scientific research. Sunpanels are a widely used building material and can also be used in sunshades and canopies.

Try to go out when the sun is not strong during the day. If you want to go out, you can wear a sunshade for your baby. Suitable for the baby to wear in summer hat, not only to achieve effective sunshade, but also to cool and breathable. Try to choose a wide-brimmed hat and the brim should be as wide as possible to block out the sun. At the same time, we should pay attention to the style and material of the hat, which is easy to dissipate heat and absorb sweat. In the selection of hats, we must pay special attention to the design of the head, not too tight, it is best to choose towels and other sweat-absorbing materials of the hat. If the hat is easy to cover and sweat, it makes the baby feel hot and uncomfortable.
