In the summer of 2013, the high temperature and high humidity in the early autumn led to the occurrence of soft rot in some plots around the demonstration site. Incidence occurs during the storage period of Chinese cabbage cabbage. At the early stage of the onset of cabbage, there was no abnormal appearance, but with the development of the disease, the symptoms became more obvious. Symptoms vary slightly depending on the diseased area and the environmental conditions. When the disease starts, the leaves wilted at noon and recovered sooner or later. Later in the fall, they collapsed to the ground, exposing the outer leaf margins to charring or the tops of the leaves rot, and sometimes the outer leaves rotted. . When the weather turns dry and dry, the decayed leaves quickly lose water and become thin paper.
Control measures: (1) Seed Sterilization: Soak Chinese cabbage seeds with 4% agricultural anti-120 (vegetable-specific) 200-fold liquid for 10 hours, and soak after drying. (2) Soil disinfection: Use 40% soil fungus net and fine soil in a ratio of 1:20 to mix medicinal soil, evenly spread on the well-cooked surface, and then sow. The 40% soil worm net has the effect of sterilizing, disinfestation and anti-double worming. (3) Control of crops during crop growth period: Spraying bactericides before spraying or spraying at the beginning of the disease. There are 72% agricultural streptomycin 3000 times liquid; neemectin 4000 times liquid; or “401†antibacterial 500 times liquid, 40% Bacteria 8000 times water can also be used to irrigate the rhizosphere soil of the diseased plants and the surrounding healthy plants. . When spraying, the petiole and stem base near the ground should be sprayed, and the plants that have already started the disease and the surrounding healthy plants should be sprayed. Sprays are usually sprayed 6-7 days in a row, spraying 3-4 times.
