Soilless culture method of drought-resistant flowers in open-air roof

Abstract

The invention discloses a soilless culture method of drought-resistant flowers in an open-air roof. The method comprises the following steps of: manufacturing ridges with height of 12-20cm at intervals in the open-air roof by sawdust cement paste; filling a soilless culture matrix composed of 30-50% of residue after mushroom plantation, 30-50% of sawdust, 5-10% of perlite, 3-5% of plant ash and 3-5% of calcium-magnesium-phosphate fertilizer to the ridges; cultivating drought-resistant flower seedlings in the soilless culture matrix; spraying water and killing insects in a wet condition; using 0.1-0.3% of urea and 0.3-0.6% of composite fertilizer water solution to pour the seedlings during the growth period. Plants with strong drought resistance, such as portulaca grandiflora, maguey, ball cactus, cactus, calendula officinalis and sago cycas, are applied to form a roof garden, which remains green, has flowers throughout the year, is colorful and has various shapes, thus saving labor, preventing heatstroke and protecting the roof surface as well as improving ornamental value, economic value, and greening economic, ecological and social effects.

Description

technical field [0001] The invention relates to a method for cultivating flowers and plants, in particular to a method for cultivating drought-resistant flowers such as Scutellaria barbata in the open air on the roof without soil. Background technique [0002] The current status of inventions and research at home and abroad shows that: with the warming of the earth causing atmospheric anomalies and frequent natural disasters on the earth, people's protection and improvement of the ecological environment are increasing rapidly. Since my country's reform and opening up, the urbanization rate has increased greatly, and the urbanized population in the country has reached more than 52%. Due to the dense urban buildings, the population increase is constantly expanding, and the urban heat island effect is also expanding due to abnormal weather. Greening and improving the environment.

Problems solved by technology

Due to the dense urban buildings, the population increase is constantly expanding, and the urban heat island effect is also expanding due to abnormal weather. Greening and improving the environment. At present, domestic and foreign roof greening mainly carry out the following aspects of work: First, the load problem of building roof gardens is considered in the design of buildings, so roof gardens are often paved with the minimum required for planting plants. It requires a thick soil layer, and then plant flowers, trees, or vegetables on the soil layer; the second is to place flowers, trees, trees, or vegetables on the roof in the form of potted plants to achieve the effect of greening the roof; the third is to lay soilless Substrate cultivation, cultivation of sedum, sedum, weeping grass, Sedum chinensis and other plants, the soilless substrate of this kind of plants not only contains humus and peat, but also mixed with vermiculite, sawdust and mushroom substrate Residue and palm sugar and other substances grow well in the first year after cultivation, but due to the monotonous landscape and extensive management after one or two years of cultivation, it is difficult to attract people's attention. Plant degeneration, some due to the high content of peat and humus, when the rainy season in the south comes, it is easy to cause the root system to rot and die, which seriously affects the greening effect, and some all die within half a year
