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

A kind of planted roof presses down root water-loss reducer
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:
A kind of planted roof presses down root water-loss reducer, and comprise Triiodobenzoic acid (TIBA), mepiquat chloride (PIX), the mixed solution of cycocel (CCC) and water-loss reducer, in described mixed solution, the concentration of Triiodobenzoic acid is 1.0 × 10 -7-1.5 × 10 -5molL -1, the concentration of mepiquat chloride is 1.0 × 10 -4-1.0 × 10 -2molL -1, the concentration of cycocel is 5.0 × 10 -5-5.0 × 10 -3molL -1, the mass volume ratio of described water-loss reducer and mixed solution is 3.57-100 g L -1.
Be preferably: the concentration of Triiodobenzoic acid is 5.0 × 10 -6-1.5 × 10 -5molL -1, the concentration of mepiquat chloride is 5.0 × 10 -4-1.5 × 10 -3molL -1, the concentration of cycocel is 1.0 × 10 -4-9.0 × 10 -4molL -1, the mass volume ratio of described water-loss reducer and mixed solution is 4-20 gL -1.
Be more preferably:
The concentration of Triiodobenzoic acid is 1.0 × 10 -5molL -1, the concentration of mepiquat chloride is 1.0 × 10 -3molL -1, the concentration of cycocel is 9.0 × 10 -4molL -1, the mass volume ratio of described water-loss reducer and mixed solution is 5-10 gL -1; Or the concentration of Triiodobenzoic acid is 1.0 × 10 -5molL -1, the concentration of mepiquat chloride is 5.0 × 10 -4molL -1, the concentration of cycocel is 5.0 × 10 -4molL -1, the mass volume ratio of described water-loss reducer and mixed solution is 5-10 gL -1; Or the concentration of Triiodobenzoic acid is 1.0 × 10 -5molL -1, the concentration of mepiquat chloride is 1.5 × 10 -3molL -1, the concentration of cycocel is 1.0 × 10 -4molL -1, the mass volume ratio of described water-loss reducer and mixed solution is 5-10 gL -1.
Most preferably be: the concentration of Triiodobenzoic acid is 1.0 × 10 -5molL -1, the concentration of mepiquat chloride is 1.0 × 10 -3molL -1, the concentration of cycocel is 9.0 × 10 -4molL -1, the mass volume ratio of described water-loss reducer and mixed solution is 5-10 g/L.
Further, described water-loss reducer is preferably commercially available " section is vast by 98 " Type B water-loss reducer.
Beneficial effect of the present invention is:
But the root water-loss reducer that presses down of the present invention can be formed root water conservation separation layer, it can effectively suppress root system of plant to grow to house waterproofing course, plant upper grown is then mainly by the impact of upper strata Nutrition Soil, make plant lateral roots raised growth and slow down press down root agent on the impact of plant shoot, water-loss reducer can retain natural rain again simultaneously, thus can obviously reduce the number of times watered, can obviously extend the interval of watering, and it is longer to water water spacer, the possibility running into natural precipitation is also larger, further save with water, promote eucyclic formation, both water resource had been saved in a word, additionally reduce the expense of manual watering.
