Abstract
The invention discloses a root-inhibiting water retention agent for a planted roof. The root-inhibiting water retention agent contains a mixed solution of triiodobenzoic acid, mepiquat chloride and chlormequat chloride and a water retention agent, wherein in the mixed solution, the concentration of the triiodobenzoic acid is 1.0*10<-7> to 1.5*10<-5> mol/L, the concentration of the mepiquat chloride is 1.0*10<-4> to 1.0*10<-2> mol/L, the concentration of the chlormequat chloride is 5.0*10<-5> to 5.0*10<-3> mol/L, and the mass/volume ratio of the water retention agent to the mixed solution is 3.57g: 100L. According to the root-inhibiting water retention agent for the planted roof, roots of plants can be effectively inhibited from growing towards a waterproof layer of a building, and the growth of the upper parts of the plants is mainly affected by nutrient soil of an upper layer, so that lateral roots of the plants grow extensively, and the influence on the upper parts of the plants caused by a root inhibiting agent is retarded; meanwhile, due to the water retention agent, the number of times of watering can be obviously reduced, and the interval of watering is prolonged, so that water resources are saved, and the cost for manual watering is reduced.
Description
Technical field
The invention belongs to horticultural field, be specifically related to a kind of for planted roof press down root water-loss reducer.
Background technology
Green plants can releasing oxygen, manufacture organic matter and beautify the dwelling environment of the mankind.The world today, because the irrational utilization of the mankind to natural resource causes the continuous deterioration of global environment quality, people have recognized that green plants is directly connected to the existence of the mankind.
Urban green coverage rate can be improved in roof garden, and reducing " heat island " effect, is current and the trend of future city architectural development.But planted roof root system of plant puncture ability is strong on the one hand, very easily causes roof waterproof damage layer and makes building leakage; Roofing phytoremediation relative difficulty on the other hand.Therefore, for planted roof Problems existing, the present invention proposes to increase between planted roof plant nutrient soil and building waterproof layer to press down root water-loss reducer separation layer, as shown in Figure 1, presses down root water-loss reducer separation layer and root system of plant can be suppressed on the one hand to roof building structure puncture growth; Water-loss reducer can be utilized again to retain natural rain on the other hand, under the Nutrition Soil arid situation of upper strata, by water-loss reducer, the moisture of absorption slowly be supplied plant absorption by osmosis utilize, both saved water resource, and additionally reduced the expense of manual watering.
Summary of the invention
Root system of plant puncture roof membrane for current roof garden causes building leakage and roof plants to supply water difficulty two large obstacles, the invention provides a kind of for planted roof but root water-loss reducer.
The technical scheme that the present invention solves the problems of the technologies described above is:
