The invention discloses a special organic fertilizer for tea oil trees planted in south red soil regions and a preparation method thereof. Fresh dairy manure is taken as the main raw material, rice bran or mushroom residue is taken as the auxiliary material, and the fertilizer also comprises humic acid, a calcium magnesium phosphorous fertilizer, borax, zinc sulfate, ferrous sulfate, amino acids,and powdery fermentation bacteria. The preparation method comprises following steps: evenly mixing and stirring fresh dairy cow manure and urine to prepare a pasty mixture; then evenly mixing the mixture with the auxiliary material, carrying out fermentation; after fermentation, adding zinc sulfate, borax, ferrous sulfate, humic acid, and amino acids; and carrying out resonance vibration and finefiltering to obtain the finished product. The raw materials are simple and easily available, the technology is simple, the production cost is effectively reduced, the organic substance content of thefertilizer is high, and the fertilizer can continuously and effectively improve the soil for a long term, relieves soil hardening, and prevents diseases and pests.

The invention discloses wall facing mortar as well as a preparation method and a use method thereof, and belongs to the technical field of building wall decoration materials. The wall facing mortar comprises the following components in parts by weight: 10-30 parts of Portland cement, 10-50 parts of red soil and 30-70 parts of quartz sand. The wall facing mortar is 100% inorganic mortar, does not contain organic additives, is beneficial to energy conservation, emission reduction and voc control, is more natural and attractive in decoration effect, and avoids the situation of poor fire resistance caused by the organic additives. By utilizing the characteristics of the red soil,the compressive strength and breaking strength required by the mortar as a whole can be ensured, meanwhile, the high-temperature fire-resistant and alkali-efflorescence-resistant effects are also achieved, the national A1-level fireproof performance of decorative materials can be achieved, and the application range of the facing mortar in places with the building specification A1 requirements such as public buildings is widened. The invention solves the problem that at present, some anti-crack mortar and thermal insulation mortar cannot be directly used on an exposed facade, and the facing mortar is a 100% inorganic mortar product capable of directly exposing the facade.

The invention relates to a constant-speed identification system using transparent clamping grooves. The system comprises: a clamping groove conveying mechanism which has one end located in a planting area and the other end located in a packaging area, comprises a conveying motor and a plurality of parallel hinges are driven by the conveying motor and are buckled in pairs, and is used for conveying a plurality of transparent clamping grooves which are uniformly formed in the side-by-side hinges at intervals at a constant speed; and the multiple transparent clamping grooves, wherein a watermelon is fixed on each transparent clamping groove, and the transparent clamping grooves are used for conveying each watermelon from the planting area to the packaging area under the conveying of the clamping groove conveying mechanism. The constants-peed identification system applying the transparent clamping grooves is compact in design and reliable in logic. The customized identification system composed of the clamping groove conveying mechanism, the transparent clamping grooves, a double-camera-shooting mechanism, ultrasonic detection equipment and a linkage mechanism is introduced, so that whether the watermelons are in a red soil leakage rupture state or not can be determined based on the area size of the area defined by the red soil pixels, and defective products are prevented from flowing into the market.
