On the one hand, the selection of shade-tolerant and moisture-tolerant pea varieties with strong stress resistance can reduce the decline in pod setting rate from the source; on the other hand, supporting scientific cultivation management such as reasonable dense planting, perfect drainage, and timely plant protection can minimize the losses caused by continuous rain. In production practice, both are indispensable. It is difficult to achieve ideal results if there are only stress-resistant varieties but poor management, or only relying on management to make up for the weakness of the varieties themselves. This study once again confirmed the importance of integrated disaster prevention technology through a systematic analysis of varieties, physiology and management. For example, the case of Qiubei, Yunnan shows that the use of shade-tolerant varieties and strengthening field management can still achieve good harvests in years of continuous rain; while the fields without supporting measures suffered heavy losses. It can be seen that in order to bring out the potential of disaster-resistant varieties, it must be supported by sophisticated cultivation technology. Especially in the current climate change, "disaster-resistant varieties + emergency management" should be considered and promoted as a whole. The government and scientific research and promotion institutions should strengthen technical training for farmers so that advanced disaster prevention concepts and measures can be deeply rooted in the hearts of the people. At the same time, through policy guidance, we encourage planting cooperatives and large households to adopt new varieties and technologies, set up demonstration models, and achieve point-to-surface. Only when the selection of suitable varieties and scientific management are truly combined with production practice can we effectively improve the pea production system's ability to resist disasters such as continuous rain and ensure stable agricultural production and increase. In the face of extreme weather events that may become more frequent in the future, research and countermeasures on the impact of continuous rain on peas and other grain and bean crops need to be further deepened. For example, my country's edible bean industry has seen a decline in export advantages and an increase in import shocks, and it is necessary to learn from international experience to enhance the risk resistance of local production. In the context of climate change, frequent extreme weather has become a challenge that agriculture must face. In the future, we should respond to this challenge with more open ideas and more sophisticated technical means, and work together in genetic improvement, cultivation management, and agricultural meteorological services. In terms of genetic improvement, we should strengthen the study of the genetic mechanism of peas' resistance to stress traits such as low light and moisture tolerance, discover related functional genes, and use molecular breeding methods to cultivate new varieties that are both high-yielding and resistant to continuous rain. In terms of cultivation technology, more innovative measures can be explored to alleviate the harm caused by continuous rain, such as developing low-cost rain shelter and covering facilities, establishing intelligent monitoring and emergency lighting and moisture removal systems, etc. In terms of agricultural meteorological services, it is necessary to establish a forecasting and early warning model for continuous rain disasters and a disaster reduction countermeasure library. Once it is predicted that continuous rain will occur, early warnings can be issued and professional technical guidance can be organized to minimize losses. In short, the impact of continuous rain on the pod setting rate of peas is a complex agricultural issue that requires coordinated response from scientific research, promotion and production entities. Only by continuously strengthening variety resistance and improving agronomic measures, and enhancing the adaptability of the production system, can we ensure that important crops such as peas can be produced stably under various weather conditions and contribute to maintaining food security and sustainable agricultural development.
