A wavelet domain Retinex image defogging method, the purpose is to improve the defogging effect of the Retinex algorithm and improve algorithm efficiency. The method includes the following steps: transform the image into HSV color space; perform wavelet transformation on the brightness component V to obtain the low-frequency sub-band where the fog component is located and the high-frequency sub-band where the noise and edge information are located; The sub-band is processed, and the high-frequency sub-band is processed by the wavelet threshold method; the wavelet inverse transform is performed to obtain the reconstructed brightness component; the saturation component S is adaptively adjusted according to the change of the brightness component V; according to each HSV after the change The color space component reconstructs the clear image after removing the fog. The dehazing algorithm designed by the invention can effectively improve the degeneration phenomenon of the image in foggy weather, improve the definition of the image, and significantly improve the processing efficiency.

The invention discloses an open-pit mine internal drainage stratum reconstruction method for rapid fertilization by increasing the soil moisture content. In the internal dump site, a soil layer, an aquifer, a water-repelling layer, and a conventional soil drainage layer are sequentially arranged from the surface downwards. A number of water collection channels are laid horizontally at intervals in the soil layer, and the top surface of the water collection channels is exposed to the surface. A plurality of water diversion blind alleys are horizontally laid at intervals in the soil layer. The water blind alley intersects with the water collection canal, and a water guide blind alley is divided into multiple sections by multiple water collection canals; the fertilization and water replenishment seepage pipe is laid inside the water collection canal, and the laying direction of the fertilization and water replenishment seepage pipe is the same as that of the water collection canal. Fertilization and water replenishment wells are arranged longitudinally in the initial section, and the fertilization and water replenishment wells are connected with the seepage pipes for fertilization and water replenishment. The invention reduces the evaporation of soil moisture, increases the rainfall infiltration, can realize rapid fertilization and water replenishment under the condition of weak ecological self-repair ability in the early reclamation stage of the inner dump site, saves reclamation cost and improves the survival rate of vegetation.

The present invention discloses a geranialdehyde nanoemulsion under an acidic condition and a preparation method thereof. The geranialdehyde nanoemulsion under the acidic condition consists of the following raw materials in weight percentages: 0.1-1.5% of geranialdehyde, 0.5-2.0% of emulsifier, 1.0-15.0% of oil phase and the balance being an acid buffer solution at a pH of 2.0-5.0. The present invention also provides a preparation method of the geranialdehyde nanoemulsion. Firstly the acid buffer solution at the pH of 2.0-5.0 is formulated and then the emulsifier and the buffer solution are mixed to obtain an aqueous phase component. The geranialdehyde and the oil phase are mixed to obtain an oil phase component. The aqueous phase component is added into the oil phase component to form a macroemulsion. The macroemulsion is then homogenized to obtain a geranialdehyde containing nanoemulsion which is uniform in particle size distribution. By a gas chromatographic analyzer test, after the prepared geranialdehyde nanoemulsion stored for two weeks, the geranialdehyde nanoemulsion still contains a large amount of geranialdehyde and less degradation products, indicating that the geranialdehyde nanoemulsion improves the stability of geranialdehyde in an acidic environment.
