Current main drought prevention opinions in crops

In areas where rivers, reservoirs, and mountain ponds have sufficient water resources for rice cultivation, it is essential to implement water-saving practices such as controlled irrigation and avoid excessive flooding. For rice fields that have recently experienced dehydration, if water is available, it's recommended to apply foliar fertilizers or drought-resistant agents to the seedlings, enhancing their resilience against dry conditions. In severely drought-affected open rice fields, spraying the seedlings during early morning and late evening can help reduce leaf water loss and maintain root vitality, thus supporting healthy growth and drought resistance. For dry corn and summer maize, timely watering, spraying, and drought management are crucial. During the early growth stages of early autumn corn, sweet potatoes, and autumn soybeans, soil should be tilled promptly to break up the capillary action, and grass should be mowed. Alternatively, straw mulching can be used. Applying drought-tolerant agents like "dry land dragon" can further improve crop resilience under dry conditions. Vegetable farms and large-scale growers should adopt water-saving irrigation techniques such as drip and sprinkler systems. Proper field management, including timely tilling and shallow weeding, not only improves soil aeration and root development but also breaks soil capillaries, reducing moisture loss. Covering the soil with straw or organic mulch helps retain soil moisture, lower temperatures, and minimize evaporation. Fruit orchards, tea plantations, and mountain gardens should be shaded to protect from direct sunlight and reduce water evaporation. Timely harvesting of fruits such as peaches, plums, pears, and melons can help prevent economic losses. Pest control is also important—citrus growers should focus on managing rust mites and red spider mites, while tea farmers should monitor and control small green leafhoppers to minimize production losses. After rainfall, replanting fast-growing vegetables such as autumn corn, sweet potatoes, potatoes, radishes, and cabbages promptly can prevent land from being left idle and ensure continuous productivity. These measures help optimize resource use, enhance crop resilience, and support sustainable agricultural practices in challenging weather conditions.
