Embodiment

[0024] 1. Land selection, soil preparation, base fertilizer application

[0025] 1. Site selection: In the Dongming area of ​​Shandong Province, the sandy soil with fertile soil, deep soil layer, and rich humus content is selected in this area, which is good for drainage.

[0026] 2. Apply base fertilizer: apply 500 kg of bio-organic fertilizer and 50 kg of compound fertilizer per mu. The bio-organic fertilizer was purchased from Yantai Zhongde Bio-organic Fertilizer; the compound fertilizer was purchased from Shima Brand Compound Fertilizer 12-12-17-2+TE;

[0027] 3. Soil preparation: Deeply plow the soil 25-40 cm before planting to provide a loose growth environment. Cover the surface with subsoil to reduce the growth of weeds, diseases and insect pests.

[0028] 2. Seed selection and planting

[0029] 1. Selection of improved varieties: Select plants with strong rhizomes, strong growth, high yield, no pests and diseases, and high content of active ingredients such as res...

Abstract

The invention relates to planting of polygonum cuspidatum, in particular to a planting method for improving the yield and quality of polygonum cuspidatum. The method comprises the following steps of firstly, preparing land, deeply ploughing the soil by 25-40cm, and then applying bio-organic fertilizer and compound fertilizer; secondly, selecting excellent plants for root division propagation; performing ridging again, dipping roots with humic acid water-soluble fertilizer, and performing transplanting and planting; then performing field management and weeding, spraying seaweed foliar fertilizer in the squaring stage (the first ten days and the middle ten days of June), topdressing quick-acting fertilizer in the flowering stage (the last ten days of July to the first ten days of August), performing watering thoroughly after application, and the enabling soil water content to be kept at 40%-50%; and finally harvesting roots and rhizomes in September of the third year of planting. The method is simple and easy to operate, can effectively prevent root rot and harm caused by continuous cropping planting, controls the heavy metal and pesticide residues to be lower than the national standard, improves the quality of polygonum cuspidatum, and increases the yield by about 10-20%.

Description

technical field [0001] The invention relates to the planting of Polygonum cuspidatum, in particular to a planting method for improving the yield and quality of Polygonum cuspidatum. Background technique [0002] Polygonum cuspidatum is a plant of Polygonaceae, a perennial herb whose roots and rhizomes are mainly used as medicine, and the fresh and tender stems and leaves of Polygonum cuspidatum are edible.
