After the autumn season, it's crucial to focus on the management of greenhouse crops such as eggplants, tomatoes, peppers, and kidney beans. This includes proper uncovering of greenhouses, cold insulation, and dehumidification. To prevent diseases, apply 50% carbendazim WP diluted 800 times or 75% chlorothalonil wettable powder at 600 times every 7 to 10 days. It's also important to spray 2,4-D or anti-dropping agents during flowering. Once the fruits start setting, gradually increase the frequency and concentration of topdressing, combining foliar sprays with 0.1% urea and 0.1% potassium dihydrogen phosphate. For bacterial wilt in tomatoes and eggplants, use agricultural streptomycin. To manage virus diseases, apply cleaning agents like "Clean Virus" or "Virus A." For Verticillium wilt, use root drenches with products like Dithane or thiophanate-methyl.
For cucumbers, timely harvesting is essential, and any misshapen or curved fruits should be removed promptly. Ensure adequate moisture, especially during flowering. Apply fertilizer in three stages: early, middle, and late fruiting periods. To prevent downy mildew, use Kelu or Dasheng sprays, while powdery mildew can be controlled with Fuxing.
Cruciferous vegetables like cabbages, Chinese cabbages, rapeseed, and radishes require careful nutrient management during their growth stages. Radishes benefit from a heavy topdressing after the seedling stage and before the "break belly" phase. Regular harvesting and timely topdressing are vital. Strengthen pest and disease control, including diamondback moth, aphids, leaf miners, clubroot, and viral infections. Use insecticides like Acephate for Plutella xylostella, and apply Dagong Chen for aphids. For bacterial soft rot, use streptomycin or other appropriate pesticides.
In late October, leeks are shaded, and their roots are covered. They are typically harvested 4 to 5 weeks after planting. Cut the leeks just 1 cm above the base and ensure even cutting. After harvesting, they are watered and decomposed. During winter (mid-to-late November) and spring (late March to April), simple softening techniques can be applied using either a canopy cover, soil pressing, or a combination of both. After harvesting glutinous rice, transparent film can replace soil to grow barley, which is then softened after one month.
For mushroom cultivation in autumn, it's important to change the bag cultivation method, protect the buds, and manage the mushrooms carefully. After the initial growth phase, when white mycelium appears and forms a pellicle, adjust the environment by providing dry-wet cycles, temperature, and light stimulation to encourage reproductive growth. As temperatures drop, focus on moisture retention and insulation. Cover the mushrooms during the day to warm them and ventilate in the morning by lifting the cover and spraying water to cool down. This helps create the ideal temperature and humidity conditions. Harvest the first batch of mushrooms when they reach 7–8 cm in height to ensure optimal quality.
