Chrysanthemums, except for seed propagation and grafting, are mostly used for cutting seedlings. However, because of the complex production process, the long production cycle and the large amount of management work, the survival rate of cutting seedlings is affected to varying degrees. In recent years, all-light spraying and soilless cutting methods have been adopted to reduce the management workload and the chance of pest infestation and ensure the appropriate temperature and humidity. The cuttings are rooted 5 to 7 days in advance, and the survival rate is above 98%. The specific measures are as follows. 1. The slotting machine is ready to be sheltered from the wind and the terrain is high. A cement pool with a height of 30 cm and a long and wide depending on the scale of production is used as a pool for slotting. Several drainage holes are left at the bottom of the pool to facilitate the timely discharge of accumulated water. The tank is filled with 25 cm thick ash as a bed matrix, and then on the insertion bed about 50 cm high, a number of agricultural sprayer nozzles are installed at an appropriate distance. So that it can spray and all cuttings. After spraying the spout, spray water once to make the matrix ready for use. 2. Selection and cutting of cuttings From late April to July, according to the different characteristics of the varieties and the need of plant modeling, cuttings of top branches were cut in batches. One or two days before the cutting, when the cuttings are still on the mother plant, first use a mixture of fungicides and insecticides to spray 1 time, the next morning to cut about 10 cm of strong twigs for litchi, avoid two sections Branches (without tip branches). Because the two branches are white flocculent hollow, perishable necrosis, not easy to survive. Then cut 1 inch at the base section with a blade, cut the two blades of the lower part of the cutting, retain all the upper leaves, and insert the cuttings into the matrix about 3 cm, then open the spray valve, adjust the spray angle, ensure that each A cutting can be sprayed into water. 3. Post-insertion management For the first 10 days, except for rainy days, spray continuously during the day, stop spraying at night, and gradually reduce the number of sprays after 10 days, and spray only a few hours before and after noon after half a month of spraying. Windy weather should be observed, and adjust the spray angle at any time to prevent cuttings from losing water and death. 4. Post-transplantation and post-planting care A large number of rootings survived after 20 days of insertion. The upper pots should be grasped and transplanted. Due to the lack of nutrients in the ash matrix, the root system was too late for aging. The basin soil must be well drained, and no fertilizer should be added. The mixture of honeycomb ash and garden soil can be evenly mixed. The seedlings of the upper pots should be cut to one leaf of the base, and the upper leaves should also be cut off by one third to reduce the evaporation area and to facilitate survival. After planting in the arbours, it is sprayed several times a day, and after 10 days, sunshine can be increased as appropriate, and then it gradually transitions to normal management.
Disposable Endo Retrieval Bag
A disposable specimen recovery bag is a single-use bag designed to collect and transport biological or medical specimens from one location to another. These bags are typically made of durable, leak-proof materials and feature a secure closure mechanism to prevent spills or contamination. Disposable specimen recovery bags are commonly used in hospitals, clinics, and laboratories to transport samples of blood, urine, tissue, or other bodily fluids for diagnostic testing or research purposes. Once the bag is used, it is disposed of in accordance with biohazard waste regulations to prevent the spread of infectious diseases.
1. Hygienic: Disposable specimen return bags are a very hygienic option because they are used once and then discarded. This helps prevent the spread of infection and cross-contamination.
2. Convenience: These bags are very convenient to use because they can be easily disposed of after use. This eliminates the need for cleaning and disinfection, which can be time-consuming and expensive.
3. Safe: Disposable specimen return bags are a safe choice as they are made of tear and puncture resistant material. This helps prevent accidental release of hazardous substances.
