The invention discloses a large-scale production method for Weining codonopsis pilosula. The large-scale production method includes a seedling raising method and a transplant method. Seedling raising is performed in a greenhouse, and transplant is performed under an open-air condition. The seedling raising method includes seed pretreatment, land selection, a seeding method, a fertilizing method and different mulch overshadowing measures, so that Weining codonopsis pilosula seedling raising in protected areas at different altitudes is achieved, emergence rate of Weining codonopsis pilosula seedlings is increased and growth period of the Weining codonopsis pilosula seedlings is shortened. The transplant method includes land arrangement; livestock (cattle or mule) furrowing during transplanting, wherein furrow depth is about 20cm, furrow surface inclination is 15 degrees, the codonopsis pilosula seedlings are placed in furrow surfaces according to the row spacing of 10cm, decomposed farm manure is applied to near roots of the codonopsis pilosula seedlings and soil dug out from next furrows covers the codonopsis pilosula seedlings finally; middle-term management, namely, using a hoe for hoeing weeds along gaps during weeding; during top application, spreading fertilizers at the near roots of the codonopsis pilosula before weeding, and covering by the soil shoveled by weeding. Small inclination during transplant is beneficial to codonopsis pilosula growth, so that growth of thick and large codonopsis pilosula is promoted and yield and quality are improved.

The invention relates to a culturing method for preventing and repairing citrus yellows. The method comprises the following steps: planting, cutting lateral roots, managing fertilization, remaining fruit quantitatively, and constructing a drainage and irrigation system, wherein the step of cutting the lateral roots is that a strip-shaped ditch is dug between plants or rows for cutting the lateral roots after the blossoms of citrus fell, and a root repair agent is sprayed and applied immediately after the lateral roots are cut; the step of managing the fertilization comprises fertilizing a post-blossom falling fertilizer heavily, spraying a leaf fertilizer, and applying an organic liquid fertilizer at a root, wherein the step of fertilizing the post-blossom falling fertilizer heavily is that 16 to 32 kilograms of self-made fertilizer is applied to each plant by combining deep plowing and soil improving after the lateral roots are cut; orchard wedding is combined when the fertilizer is applied, weeds, the fertilizer and soil are fully and uniformly mixed and then are backfilled into the strip-shaped ditch. The culturing method for preventing and repairing the citrus yellows provided by the invention has the advantages of simple method, high operability, good effects on preventing and repairing the citrus yellows and the like.

Disclosed in the invention is a solar lighting flowerpot. The flowerpot comprises a flowerpot body (1), a pedestal (2), and a main solar cell panel (3). A drive motor (4) is arranged on the pedestal (2), wherein a gear wheel is fixed on a rotating shaft of the drive motor. Teeth engaged with the gear wheel of the drive motor (4) are arranged at the outer side wall of the bottom of the flowerpot body (1). A water storage cavity is arranged at the bottom of the pedestal (2). A hollow pipe (5) is fixed at the center of the base plate of the flowerpot body (1) vertically and sleeves a bearing of the pedestal (2) vertically. The inner cavity of the flowerpot body (1) is connected with the hollow pipe (5). According to the invention, the flowerpot has advantages that the sunlight can be received at all directions and uniform lighting on flowers can be kept.
