Green greening 1.1 Ecological balance and a good living environment of the living environment within a specific range A green roof is a natural air conditioner: in recent years, the number of urban buildings has increased. The accumulation of buildings can also increase, coupled with the continuous sources of energy for home fuel, industry, and motor vehicles, which causes the energy of the urban climate, especially in the summer, compared with the areas without buildings, the city has no building. The inner temperature rises significantly. In the densely building urban area, due to the shortage of water shortage in the summer, it will have an unbearable high temperature. Due to the low reflection of the building to light, the cooling at night will be weakened. Negative effects, and green zones and green roofs can reduce natural radiation by about 80%through the moisture and growth plants of the soil to reduce the side effects of the building. In the experimental proof, compared with the roof without greening, the green roof can cool down. In the hot summer, when the temperature is 30 degrees, the ground without greening has reached 40-50 degrees that the green floor is unbearable. At 10cm, the temperature is comfortable 20 degrees. In winter, the green roof is like a warm cover to protect the building. 1.2 Protection of the architectural structure layer The flat roof building, the destruction of the roof structure is caused by the temperature stress of the roof waterproof layer, and a small part of it is caused by load -bearing objects. Causes the expansion and contraction of the roof structure, causing the building to crack, causing the penetration of rainwater. Formation. The "Administrative Measures for the Quality of Construction Engineering" clearly stipulates that the waterproof period of waterproofing of the roof of the building is only three years. In this way, the roof waterproof layer must be renovated. The temperature of the rapid change of air is particularly harmful to the building. For example, in winter, after a cold night, during the day, the temperature on the surface of the building suddenly rises in a short period of time. ; Summer, after cooling at night, the temperature on the surface of the building will soon rise significantly. Due to the changes in temperature, the building materials will receive a large load, the intensity will be reduced, and the life will be shortened. If the roof is green, it can not only adjust the extreme temperature of summer and winter, but also play a considerable role in protecting building components. Therefore, the roof garden can protect the building and even extend its life. 1.3 The greening of the roof can be stored through water storage, reducing the roof leakage, and reducing the pressure of the urban drainage system . When the urban construction is under construction, the surface water will form a closed layer due to the building and land on the surface of the building surface. The water will be led to the drainage ditch through the water drainage device, and then it is not transported to the clarification pool or directly transferred to a natural or artificial drainage facility. Continuously rising, the final result of this malignant cycle leads to severe exhaustion of groundwater resources. Compared with the ground without building a house, a large amount of precipitation cannot be excreted in a short period of time, which will definitely cause the flood in the city. The pressure of the drainage system can also significantly reduce the cost of processing sewage. In many cities and regions in modern times, roof water is not used as a very valuable natural resource, but mixes it with the water that is severely polluted as a wastewater treatment. The cost is quite expensive. It when many roofs are greened, the roof drainage can be reduced in large quantities. Experiments show that the green roof can reduce the precipitation strength by 70%(the Badelia Horticulture Station), which can undoubtedly be used as a basis for determining the water pipeline in the drainage project. 2. The type of crop planting 2.1 Jingtian wild vegetables Jingtian wild vegetables are also called Jingtian Sanqi, Fei Cai Jiangsu Sanqi Seven -saving Severed Caipan The hemostatic grass is a perennial wild meat -based herbaceous plant. Leaf can be processed into savior tea. It can be used as medicine for all grass, which is a wide -range high -efficiency herbal medicine commonly used by the people. Potted plants can be dotted in the balcony of the living room, or it can be embellished in the flower bed or garden green area, which has high practical value. The plant is 15-50cm, leafyanoids, 3 to 5 cm long, non-petiole, slightly serrated on the edges, thick and fleshy, green. In the summer of July to August, the stems are branched with yellow flowers, yellow flowers and green leaves, bright and eye-catching. Can be planted in large areas in the field. Urban residents can be planted on the roof platform, replacing the turf as the thermal insulation layer, improving the ecological environment of the roof, and cooling and dampness. Jingtian vegetables have long green period, and can be used as plant -shaped materials to make a variety of shapes. In research and measurement, every 100g of fresh food contains 2.1g of protein, carbohydrate 8g, fat 0.7g, crude fiber 1.5g, carotene 2.8mg, vitamin B1 0.05mg, vitamin B2 0.31mg, vitamin C95mg, smoke Acid 0.9mg, calcium 315mg, phosphorus 39mg, iron 3.2mg. Freshly vegetable soup soup is fresh, and the meat is delicious. It can be used for cooling, cooking, and making soup, which is loved by people. The wild vegetables contain drug components such as alkaloids, schunolic acid, glycol, flavonoids, Jingtian Gengtang, fructose and vitamins. These drugs components can prevent blood pressure, preventing stroke, anti -heart disease (such as coronary heart disease, upset heartbeat, arrhythmia, rheumatoid heart heart, rheumatoid heartbeat, rheumatic heart, rheumatoid heartbeat, rheumatism, rheumatism, rheumatic heart The effect of disease, etc.). 2.2 Scenic wild vegetables have the characteristics of easy to plant and can manage and reproduce quickly. Most of the Jingtian vegetables use cuttings, and the ranging rate of Jingtian cuisine is extremely high. A Jingtian cuisine can breed 1,000 a year. Jingtiancai is not strict with the soil, but it is best to be sandy loam, not afraid of strong light, not afraid of heavy rain. Generally, fertilization is not applied. It is mainly harvested (harvesting is similar to leeks, and the stems and leaves above the ground) must be applied once. In short, it is easier for Cai Cai to resist reverse resistance and strong vitality. Cutting seedlings and cultivation management are easier. 3. The conditions for planting ............ n 3.1 When selecting the planting substrate and plant, the weight of the material should be considered first. In addition to the planting medium, you can also use new planting substrates. The weight of the new substrate is relatively light and has good moisturizing and permeable. The roof garden is suitable for planting some low shrubs, flowers, and lawns. It is best to plant in a barrel or wooden box and other containers and place it on a load -bearing wall or load column. 3.2 although Jingtiancai is a perennial plant, it is best to cut or divide again after planting for one year, because the old plant grows poorly and it is easy to rot. Jingtian dishes are more cold-resistant and can resist the low temperature at -5 ° C for a short time, but low temperature will affect the growth of the second year. Therefore, when the exposure of the southern region is cultivated in the winter, when the temperature in winter is 0 ~ 5 ° C, it should be covered with a thin film or grass curtain to avoid frost and snow; the potted plants can be moved to the south eaves. The northern region should move into the greenhouse or greenhouse to overwinter. There are fewer pests in Jingtian cuisine, and the disease is mainly root rot. As long as the soil disinfection is made, and new soil and new seedlings are changed every year to prevent it. The pests are mainly sticky insects, leafyfes, land tigers, and snails. They should be used for artificial killing and try not to spray pesticides as much as possible. In severe cases, you can spray high -efficiency and low toxic pesticides, and it is necessary to prohibit fresh grass within half a month after spraying to avoid poisoning. The as a healthy vegetables, in order to extend the harvest period, keep it fresh and delicious. In summer, it should be cultivated with shading nets to control the temperature and light, and delay the fibrosis of the vegetable body. You can also refer to the method of cultivation of vegetables to be cultivated in a cool area in summer. The ecological habits of Jingtian wild vegetables are expensive and cold -resistant. Beijing can overwinter winter, expose light, drought resistance, not strict requirements on the soil, not afraid of strong light, not afraid of heavy rain. Cultivation management is simple, generally no pests. Mainly breeding with cuttings: Cut Fei Cai's tender branches for cuttings in the growth season, 8 to 10 cm long, 3 to 4 leaves on the upper end, and cutting depth of 1 to 2 cm. The cutting matrix should be used with good ventilation, both water preservation and well -drained materials, such as perlite, vermiculite, and river sand. Put the water, cover the film on the top, and place it in the semi -yin. Spray water at the leaf surface 1 or 2 times a day, keep the air humidity of about 90%, and the temperature is 25 ° C. Take root from 7 to 10 days, and can be planted in 20 to 30 days. The wild vegetables are not strict with soil. Fields that can grow dry crops can be planted. Sprinkle 3,000 kg of organic fertilizer per acre, and 50 kg of multi -element compound fertilizer. It deeply cultivates fine rakes, and it has been tied to 2 to 2.5 meters wide. Plant density, row distance 25 cm, acupoint distance 15 cm, 2 to 3 plants per hole. Cai Cai is cold -resistant and can grow overwinter in winter. It is suitable for large -scale production of open fields. Jingtiancai is consumed, medicinal, roof green, and ornamental. The family planted several bonsai Tiancai vegetables with practical value, but also beautified the environment and purified the air.
