The invention relates to a carrier for realizing long-acting controlled release of cinnamyl aldehyde based on synergism of bacterial cellulose and polylactic acid, a preparation method of the carrier and application of the carrier in fresh keeping of fruits and vegetables, and the preparation method comprises the following steps: firstly, placing the bacterial cellulose in a deep eutectic solvent system containing citric acid, glycerol and choline chloride, and heating for reaction to obtain CABC; then, the CABC is placed in an activation system containing the 1-ethyl-3-(3-dimethylaminopropyl) carbodiimide and the N-hydroxysuccinimide, and CABC-ONH2 is obtained; then, the CABC-ONH2 and cinnamyl aldehyde are subjected to an oximation reaction, and CABC / CIN is obtained; and finally, mixing CABC / CIN with polylactic acid to form a film, so as to obtain the bacterial cellulose / polylactic acid synergistic cinnamyl aldehyde long-acting controlled release carrier. Compared with the prior art, initial burst release of CIN in the degradable carrier is effectively reduced, and the release stability and activity retention rate in the middle and later periods are improved; the cooperative processing suitability with PLA is improved; the antibacterial and antioxidant effects are simultaneously realized in the fruit and vegetable fresh-keeping application.

The invention provides a spliced silicon rod processing method and a silicon wafer processing method, and the method comprises the steps: bonding at least two short round silicon rods in the axial direction of the short round silicon rods through a first glue layer, and forming a spliced round silicon rod; squaring the spliced round silicon rod to form a spliced silicon rod; and before the wire cutting process is carried out, at least part of the first adhesive layer in the spliced silicon rod is removed to form a spacer region. Before the wafer cutting procedure is carried out, at least part of the first adhesive layer in the spliced silicon rod is removed to form the interval area, the interval area can provide an expansion space for the first adhesive layer which absorbs water to expand due to cutting heat, wafer spalling caused by the fact that the first adhesive layer is heated and absorbs water to expand when the spliced silicon rod is cut is reduced, and the yield of wafer cutting is improved.

The invention discloses a screening treatment method of cigar tobacco leaves, which comprises the following steps: measuring the initial mould content of the cigar tobacco leaves, screening and grading according to the initial mould content, and marking the cigar tobacco leaves as normal raw materials when the initial mould content is 10-105 CFU / g; when the initial mould content is greater than 105 CFU / g, the cigar tobacco leaves are marked as high-risk raw materials; the normal raw materials or the high-risk raw materials are subjected to flexible moisture regaining treatment, the flexible moisture regaining treatment time is 20-25 min, 25-30 min, 30-40 min, 40-50 min or 50-60 min, and a flexible moisture regaining product is obtained; the temperature for carrying out the flexible moisture regaining treatment on the high-risk raw materials is 58-59 DEG C; the temperature for carrying out the flexible moisture regaining treatment on the normal raw materials is 62-65 DEG C; the flexible moisture regaining product is subjected to stacking fermentation treatment, the stacking fermentation treatment time is 10-35 days, the mold content in the stacking fermentation treatment process is lower than 10 < 6 > CFU / g, and a stacking fermentation product is obtained. And carrying out enhanced moisture regaining treatment on the stacked fermentation product to obtain an enhanced moisture regaining product. The purpose of reducing the mildew rate of finished cigarettes is achieved.

The application discloses a condenser and a clothes processing device. The condenser comprises a shell assembly and a pressure relief assembly. The shell assembly is provided with a liquid inlet cavity, a liquid outlet and a condensation channel. The liquid inlet cavity is communicated with the liquid outlet and the condensation channel. The condensate can enter the liquid inlet cavity and be sprayed into a water mist surface transversely across the condensation channel through the liquid outlet. The shell assembly is also provided with a pressure relief channel, two ends of which are communicated with the liquid inlet cavity and the outside of the liquid inlet cavity, respectively. At least part of the pressure relief assembly is arranged in the pressure relief channel and is used for selectively conducting or blocking the pressure relief channel. After the condenser of the application appears the problem of blockage at the liquid outlet, the pressure relief assembly can conduct the pressure relief channel, the condensate in the liquid inlet cavity is discharged through the pressure relief channel, and the pressure in the liquid inlet cavity can be released. Therefore, it is favorable to reduce the probability of the burst problem of the liquid supply pipeline communicated with the liquid inlet cavity, and further favorable to improve the reliability of the condenser.

The invention discloses a Chinese wolfberry fruit pest green prevention and control method based on functional plants. The invention discloses a green prevention and control method for Chinese wolfberry pests based on functional plants. The green prevention and control method comprises the following steps: 1) arranging functional plant planting belts on the edge of a Chinese wolfberry plantation or two sides of a working road; 2) selecting seeds of functional plants, and sowing the seeds on the functional plant planting belt to obtain a functional plant belt; the functional plant is selected from at least one of astragalus membranaceus, radices stellariae dichotomae and scutellaria baicalensis; 3) performing water and fertilizer integrated management on the functional plant zone and the wolfberry plantation; 4, a suspended sticky trap is arranged above the functional plant zone, the migratory flying amount of the winged aphids is monitored, the occurrence trend of the winged aphids on the Chinese wolfberry branches in the field is predicted on the basis of the winged aphid trapping amount, and accurate prevention and control of Chinese wolfberry pests are guided. The Chinese wolfberry aphid breeding and harm can be reduced, the plant type and ecological niche of Chinese wolfberry are complementary, the natural enemy diversity of Chinese wolfberry pests is improved, and the pests on the Chinese wolfberry are controlled.
