Flooded and pickled vegetables have suffered damage. When the damage is severe, seedlings may be completely destroyed. In cases of mild damage, diseases such as soft rot, blight, and viral infections tend to thrive under high temperature and humidity conditions. After a storm, it's crucial to drain water from the fields promptly and refill with well or deep river water to prevent rain from washing away the leaves. Following intensive farming practices—especially after watering, fertilizing, or heavy rain—it’s important to cultivate the soil regularly.
Drought can cause damage to crops like pumpkins, loofah, peppers, and eggplants, which are prone to "melon failure" (inability to set fruit). Legumes such as kidney beans and lentils are more likely to experience "phlegm" symptoms. To avoid these issues, provide shade and ensure consistent watering. Water every 2–3 days using furrow irrigation in the early morning or evening, but avoid flooding. Keep the irrigation depth no more than half the trench, and maintain moist soil. Pests like the cutworm and cabbage worm can cause serious damage, so they should be addressed quickly. High temperatures and drought can also hinder vegetable growth and tree development. After fruit set or when plants appear weak, apply fertilizer after each harvest—1–2 times—using decomposed manure or urea. Foliar sprays of 0.2%–0.3% potassium dihydrogen phosphate mixed with 0.5% urea can also help.
If seeds are damaged or lost, replanting should be done promptly. Early autumn Chinese cabbage can be sown between late July and early August, and there's no need to wait for specific market conditions. As long as the price is favorable, planting can begin about a month ahead. Summer radishes can be planted in July, though they are best suited for cooler regions. Due to frequent rainfall in lake areas, it's not recommended for radish cultivation. Carrots can be sown from early July to early August. Autumn beans should be sown from late July to early August, not too early. Autumn cowpeas can be directly seeded from July to early August. Autumn cabbages can be planted in shaded areas from early July to late July. Autumn cauliflower seedlings should be started mid-July to early August using early or mid-season varieties for better results. Autumn tomatoes and peppers can be sown in mid-July. After fall, tomato and late pepper seedlings can be sown from mid-July to early August, but due to less price advantage compared to Hainan peppers, it's not highly recommended. Autumn celery can be started from late June to early August, and seeds should be germinated in a cool, moist environment.
In August, you can broadcast live seeds for autumn cabbage, winter radish, garlic, zucchini, spinach, leeks, garland chrysanthemum, and alfalfa. For large-scale replanting, consider red pods, autumn lettuce, green onions, and autumn potatoes. Red radishes can be planted in late August and early September. Autumn lettuce should be sown during the middle and early stages of August. Onion seedlings can be sown at the end of August. Autumn potatoes should be germinated in mid-August and transplanted by late September. Small sweet potatoes are ideal for planting.
