High-efficiency production-increasing codonopsis pilosula cultivation method

The invention discloses a high-efficiency production-increasing codonopsis pilosula cultivation method which includes the following steps of land preparation before seedling cultivation, seed preparation, sowing and quick breeding seedling culture. The quick breeding seedling culture includes that a. first-generation tissue culture seedlings are adopted as a breeding material; b. when the seedlings on a seedbed grows to 25cm and stem tips and stems are formed, the stem tips and the stems of the seedlings are taken down, the wound portions of the stem tips and the stems are immersed into 500-ppm rooting powder solution to be processed, then the stem tips and the stems are directly planted on a greenhouse hot bed of an agricultural facility and starts to survive in soil of the hot bed, and the stems tips and the stems grow for 30 days under the temperature of 28-35 DEG C to form second-generation complete plants; and c. continuously taking the stems and the step tips of the plants to conduct planting and breeding in the greenhouse hot bed of the agricultural facility after the second-generation complete plants are formed, third-generation plant seedlings are formed after 30 days, and the seedlings can emerge in the 30-day period to be planted. Autumn transplanting is a better choice in autumn sowing, and ridge planting or rest-balk planting is adopted. By means of the method, the seeds are large in seedling forming number, consumed time is short, seed quality purity is high, the production increase effect is remarkable and the method is suitable for large-scale planting.

Slope crop seeding raising method

The invention relates to a novel crop seeding raising method, belonging to the field of crop seeding raising. The seedling raising method is characterized in that a seedling raising matrix or porous seeding raising hole trays filled with the seedling raising matrix is/are placed on a slope nursery bed, which has a certain inclination angle and covered or not by a barrier material on the surface, a water and fertilizer supplying facility is erected at the high end of the slope nursery bed, water and fertilizer are provided for the seedling raising matrix by utilizing the inclined guiding action of the slope to promote the crop seeds transplanted in the seedling raising matrix to germinate, root and grow, seeding raising management is carried out, and seedlings are lifted and transplanted when the seedlings achieve proper transplanting seedling age. By adopting the method, the water and fertilizer are agilely managed, the inland inundation or drought is prevented, the disease and pest are reduced, the seedling forming rate is high, and seedling domestication is carried out by inverting the seedling raising hole trays or the nursery bed, thus the strong seedlings are effectively cultured and the seedling recovering stage is shortened; and the cultured seedlings have the characteristics of flourishing root systems, strong and trim seedlings, strong viability, few or no disease plants, short seedling recovering stage, convenience for seedling taking and seedling transport for transplanting, simplicity in operation, labor saving, cost saving, high survival rate and the like.
