The present application relates to the field of agricultural cultivation technology, and discloses a method for improving the mechanical properties of bamboo by directional nutrient fertilization, aiming at the problem of mechanical property degradation of bamboo caused by nutrient solidification in strongly acidic soil. The method divides fertilization sample plots in the bamboo forest, and applies silicon fertilizer to the rhizosphere soil of the bamboo in the sample plots by using hole-shaped fertilization method. The main component of the silicon fertilizer is sodium silicate, the application amount is controlled to be 180 kg / hm2, and the distribution density of the fertilization hole is 1 hole / m2. The present application improves the local acid-base microenvironment by using a specific dose of sodium silicate, releases the solidification state of phosphorus elements in the soil, and then directionally breeds bacterial communities participating in nitrogen cycle, significantly improves the total nitrogen content and catalase activity of the soil, and finally greatly enhances the grain compressive strength and bending strength of the bamboo stem from the micro-ecological bottom.

The utility model relates to the technical field of cup production, and discloses an intelligent paint spraying device for the surface of an antibacterial vacuum cup, the intelligent paint spraying device comprises a bottom plate, a placing mechanism is arranged on the upper surface of the bottom plate, and the placing mechanism comprises a workbench. According to the intelligent paint spraying equipment for the surface of the antibacterial vacuum cup, through the design of an automatic spraying mechanism, the automatic spraying mechanism comprises a lifting frame and a spraying pipe which are driven by an electric push rod, and a set of nozzles, simultaneous, uniform and efficient spraying of cup bodies of a plurality of vacuum cups is achieved, and through the design of a clamping mechanism, through the combination of a sliding rod, a spring, a cam and a clamping jaw, the spraying efficiency is improved; the cup body can be stably clamped under the condition that the cup body does not make contact with a paint surface, automatic transferring of the cup body after spraying and automatic feeding after spraying are achieved, the labor intensity of workers is greatly relieved, the negative effects of long-time repeated labor on the bodies and mental states of the workers are avoided, and the fan is arranged, so that the labor intensity of the workers is greatly reduced. And the curing process of paint can be accelerated after spraying is finished, and the production efficiency is improved.
