Background
Lycium barbarum L is an important medicinal and edible functional genuine medicinal material in the western part of China and is planted in 13 provinces and municipalities in China. The current standardized planting mode is as follows: the row spacing of the plants is 1m multiplied by 3m, the number of the planted plants is 222/667 m2The method is suitable for large-area centralized planting and mechanized operation, the soil between 3m rows is clear ploughed, and the problems of small plant coverage, poor sand prevention and fixation ecological effect, single biodiversity, poor disease and pest resistance, low land utilization rate and the like exist.
Stellaria dichotoma var. lancelata is a perennial herb plant in Stellaria of Caryophyllaceae, and the dried root of the Stellaria dichotoma is a traditional Chinese medicine in China, and is recorded in Bencao compendium and Chinese pharmacopoeia of the calendar edition. The starwort roots are mainly distributed in arid sandy and rainless grassland areas in Ningxia, inner Mongolia, Shaanxi, Xinjiang and other provinces, wild plants grow in desert or semi-desert areas with the elevation of 1200-1500 m, and mostly grow in fixed or semi-fixed sand dunes and dry grassland. As the bupleurum medicinal material in the market is mainly derived from wild resources, excessive mining and disorderly mining cause the wild resources of bupleurum to be seriously deficient, and the ever-increasing market requirements at home and abroad are difficult to meet. The artificial planting of Stellaria dichotoma is a necessary solution for ensuring the sustainable utilization of resources.
Therefore, the method for intercropping the Chinese wolfberry and the starwort root is developed, the land utilization rate of the Chinese wolfberry field can be improved, the plant coverage is increased, sand is prevented and fixed, the planting area of the starwort root can be increased, and the planting benefit is improved.
