Current main drought prevention opinions in crops

In areas with rivers, reservoirs, and mountain ponds that 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 in order to enhance their resilience to dry conditions. In severely drought-affected open rice fields, spraying should be done in the early morning and late evening to minimize leaf water loss and maintain root vitality, thus supporting plant growth and drought resistance. For dry corn and summer maize, timely watering, foliar 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 soil crust and prevent capillary action, which helps reduce moisture loss. Alternatively, straw mulching can be used. Additionally, applying drought-tolerant agents like "dry land dragons" can further improve crop resilience to dry conditions. Vegetable farms and large-scale growers should prioritize water-saving irrigation techniques such as drip and sprinkler systems. Proper field management, including timely plowing and shallow hoeing, not only improves soil aeration and root development but also breaks up soil capillaries, reducing moisture evaporation. Covering the soil with straw or organic mulch helps retain soil moisture, lower temperatures, and minimize water loss due to evaporation. For fruit orchards, tea gardens, and other crops, covering the ground is important to shield them from direct sunlight and reduce water evaporation. Timely harvesting of fruits such as peaches, plums, pears, and melons helps minimize economic losses. Pest control should be closely monitored—citrus growers should focus on managing rust mites and red spider mites, while tea growers need to effectively control small green leafhoppers to reduce production losses. After rainfall, quickly replant fast-growing vegetables like autumn corn, sweet potatoes, potatoes, radishes, and cabbages to prevent land abandonment and maximize yield potential. This proactive approach ensures that farmland remains productive and sustainable.
