How to carry out field management of Polygonatum? Detailed explanation of the technical key points

(1) Intertillage and weeding: After emergence, weeding should be carried out frequently, especially during the seedling stage of sown fields, where timely weeding is even more necessary to prevent large weeds from overwhelming the seedlings and affecting growth.

(2) Thinning and final thinning: When the seedlings are 5-8 cm tall, remove the overly dense small seedlings; before withering in autumn or after emergence the following year, carry out final thinning at a plant spacing of 8-10 cm. Take the thinned seedlings to a different location for transplanting.

(3) Drought prevention and drainage: Polygonatum prefers moist soil. In dry weather, water promptly to keep the soil moist; in the rainy season, ensure good drainage to avoid water accumulation in the field and prevent root rot.

(4) Topdressing: Each spring, apply 1500-2000 kg per mu of pen manure, or 50-80 kg per mu of fully decomposed cake fertilizer.

(5) Planting shade crops: When growing Polygonatum on farmland, plant corn beside the beds in spring to provide shade for the bed surface and keep the bed soil moist.
