Continuous rainfall and high temperature are important factors restricting the normal growth and development of Chinese herbal medicines in summer. Problems such as poor planting, grass shortages, serious diseases and insect pests, and even large areas of dead seedlings occur. Therefore, it is necessary to make timely plans and formulate practical and feasible field management techniques for Chinese medicinal materials to ensure the high-quality production increase and sustainability of the Chinese medicinal materials industry. 1. Pay close attention to the weather information released by the weather stations in various places, make early warnings before the arrival of heavy rains, and dig drainage ditches in advance to ensure smooth drainage. Medicinal materials that have matured or are close to maturity should be harvested and processed in time to minimize the impact of rainfall. 2. After heavy rainfall, the ditch should be cleared and drained in time to ensure unblocked drainage to reduce possible waterlogging damage. Do a good job of cleaning the flooded leaves when draining, so as to promote the recovery of roots and plants of Chinese medicinal materials as soon as possible. Especially in areas where there are many varieties of roots and rhizomes of Chinese medicinal materials, and the cultivation area is large, long-term accumulation of water can easily cause root rot, reduced production or even no harvest. 3. It is necessary to cultivate and weed in time, which is another important measure for rainy season management. Summer is a period of rapid growth of Chinese medicinal materials. Some medicinal materials are in a period of simultaneous reproductive growth and vegetative growth. It is a key period for roots to absorb soil nutrients and leaves to produce organic nutrients through photosynthesis. It is also a period for rapid growth of weeds in summer. Therefore, timely cultivation after rain can not only improve soil aeration, break moisture and promote root vitality, but also help improve plant permeability, improve leaf photosynthesis, and reduce nutritional competition between weeds and medicinal materials.
