The invention discloses a
polygonatum cyrtonema high-yield cultivation method based on dynamic
ridge expansion and ecological shading, and belongs to the technical field of traditional Chinese medicinal material cultivation. The method comprises the following steps: selecting high-quality seed stems; the seedlings are placed in ridges in a high-density single-row mode, and
bud heads face the two sides alternately during placement;
sowing high-stem crops at
ridge edges in the early growth stage and in furrows in the later growth stage so as to ecologically shade and improve the
soil structure; fine weeding is carried out by adopting a partitioning strategy; and a
dynamic management mode of'year-by-year
ridge expansion and fertilization 'is adopted. Compared with a traditional fixed ridge mode, the yield per mu can be remarkably increased by 27% or above, the occurrence rate of
plant diseases and
insect pests is reduced, meanwhile, the weeding labor cost is greatly reduced, and the
soil structure and
fertility are effectively improved. According to the method, the biological characteristics of the
polygonatum cyrtonema are accurately matched, the problems of low
utilization rate of fixed ridge cultivation
organic fertilizer, high weeding cost, later soil hardening, serious
root rot and high shading cost are effectively solved, the yield and commodity quality of the
polygonatum cyrtonema are remarkably improved, and the method is suitable for large-scale popularization and application.
