After the fall, the root rot, bacterial wilt, and epidemic diseases often occur after the peppers are transplanted, causing the plants to die, and measures should be taken to prevent and control them as soon as possible.
The main disease root rot usually occurs after planting until the fruit harvest. The diseased plants are wilted during the day and can be recovered sooner or later. The whole plant will die after repeated days. Bacterial wilt is a bacterial disease. The symptoms are not obvious at the seedling stage. After planting, it begins to die from the base of the main root, and the surface of the rhizome does not change color. The vascular bundle becomes dark brown in the vertical section. The roots and stems of the epidemic diseased plants were water-stained at the beginning and became dark brown later. They quickly rewound the stems one week later. They also harmed the branches of the stems and stems, and were generally brown or dark brown.
The prevention and control methods adhere to a reasonable rotation, and it is advisable to use cruciferous, leguminous and onion and garlic crops in the former crop to avoid continuous cropping with solanaceous and melon crops. Adjust the temperature and humidity in the greenhouse, promote small-water irrigation or drip irrigation under the membrane, and prevent the accumulation of water in the soil. Timely shallow cultivator to avoid soil compaction. Increase the use of organic fertilizers based on phosphorus and potassium fertilizers, promote the healthy growth of root leaves and enhance plant resistance. Once a diseased plant has occurred in the field, it must be removed in a timely manner, brought to a burned or buried area outside the shed, and sprayed with lime water or thiophanate-methyl, etc.
The function of Syringe set mainly contains sealing function, tunnel permeability, tensile strength, puncture performance, degree of coordination, particulate contamination, reducing substances, metal ions, ph, ethylene oxide residue, sterility, bacterial endotoxin, cytotoxicity, sensitization, intradermal reaction, hemolysis, acute systemic toxicity, etc.
A mixing system sterile Medicine Mixer (powder and liquid ) is a device that mixes powder and injection before injecting the drug into the patient.But traditional booster injection infusion dispensing still exist, need medicine soluble medicine, when dispensing, repeated shocks and mixed extraction liquid, in the process of repeated puncture easy to produce plastic particles, particles stopper is getting into the human body easily blocked blood vessels, granulation, some problems of inflammation, and the ward of bacteria, viruses, repeatedly extracting liquid easy to carry the virus in the air, infusion to the solution of the problem.
