Technical Field

The invention relates to the field of pasture planting, in particular to a drought-resistant matrix for cultivating alfalfa.

Background

The alfalfa is perennial leguminous forage widely cultivated in semiarid regions in China, has the characteristics of high yield, high quality and strong adaptability, is qualified as the king of the forage, however, as the alfalfa belongs to deep-rooted plants, has strong water consumption on soil, and commonly occurs in soil desiccation, the production of the alfalfa is gradually slowed down, the yield is continuously reduced, the grassland is degraded, the feed supply of the animal husbandry is obstructed, and the development of the grass industry and the animal husbandry is restricted.

Although screening of drought-resistant alfalfa varieties becomes an important way for improving drought resistance of alfalfa, developed root systems are often used as a main screening index for strong drought resistance of alfalfa. However, the developed root system will further enhance the water consumption of alfalfa, aggravate the soil drought and further cause the ecological environment problem of soil moisture. Therefore, from the point of view of long-term production of alfalfa and environmental sustainability, the matching research of the culture medium is carried out, and the method for improving the drought resistance of alfalfa by improving the microenvironment for growth of alfalfa, enhancing the water retention performance around the alfalfa rhizosphere and improving the drought resistance of alfalfa is bound to become a simple, efficient and sustainable approach.
