Problems solved by technology

However, at present, the development of the under-forest economy mainly relies on the coniferous forests represented by pine and fir, and there is a lack of forest medicine compound management technology for native evergreen broad-leaved tree species in subtropical regions.

Embodiment 1

[0033] 25-year-old Duying Linxia Polygonatum planting (ED):

[0034] 1. Thinning and pruning. Firstly, thin the duying plantation with too high density, remove some trees (including the tree pockets, and fill the tree pits after removing the tree pockets), and try to remove the weak growth that cannot be done. trees, and then reduce the branches below 2 meters by pruning, so that the light transmittance of the stand can be maintained at about 69%.

[0035] 2. Apply the base fertilizer by using the organic-inorganic compound fertilizer application method. According to 1-1.5 tons of decomposed organic fertilizer and 50-5kg potassium sulfate compound fertilizer per mu, mix them evenly and spread them evenly on the ground.

[0036]3. Soil loosening and land preparation, use a small excavator or a cultivator to carry out strip-shaped land preparation, plow the forest land soil at a depth of 50-60 cm, remove large rocks and tree roots in the soil, and form ridges at a width of 120-1...

Embodiment 2

[0049] Root tuber (RT) and seedling (S) of Rhizoma Polygonatum were transplanted under the Du Ying forest, wherein the tuber was 2-year-old healthy Rhizoma Rhizoma Polygonatum tuber, and the seedling was 1-year-old robust Rhizoma Rhizoma Polygonatum seedling, and the remaining conditions were exactly the same as in Example 1.

[0050] Three years after transplanting, the seeds were harvested in autumn and then excavated and processed to compare the yield of root tuber transplanted and seedling transplanted Rhizoma Polygonatum and the dry product yield after processing. The test results are shown in Table 2:

[0051] Table 2 Comparison of Polygonatum Yield with Different Planting Materials

[0052] RT S Yield (ton / mu) 4.01±0.26b 2.37±0.45a Dry product yield (%) 27.93±0.27b 23.74±0.76a

[0053] Root tuber transplanted Polygonatum yield was significantly higher than that of seedling transplantation, and the yield of dry product 3 years after root t...

Abstract

The invention provides an artificial wild cultivation method of polygonatum and relates to the technical field of Chinese herbal medicine planting. The cultivation method comprises the steps of interplanting polygonatum under an evergreen broad-leaved forest in a subtropical region, wherein the evergreen broad-leaved forest comprises a Du Ying man-made forest at the age of 5-25 years old; appropriately carrying out intermediate cutting and pruning to adjust the illumination intensity under the forest, using plump root tubers or strong seedlings of polygonatum for planting, applying a proper amount of organic fertilizer for supplementing nutrients, covering the upper part of the mown ground with a sunshade net in winter for heat preservation, and meanwhile, preventing the seeds of elaeocarpus decipiens from sprouting after falling so that the occurrence of weeds and small saplings can be reduced. The method can promote the growth of polygonatum, reduce weeds, greatly increase the yieldof dried polygonatum products and realize high-quality, efficient and artificial wild cultivation of polygonatum. In the method, the yield of the dried polygonatum products is increased by more than 1%.

Description

technical field [0001] The invention belongs to the technical field of planting Chinese medicinal materials, and in particular relates to a method for imitating wild cultivation of Polygonatum. Background technique [0002] Polygonatum is a plant of the genus Polygonatum in the family Liliaceae. It is a homologous plant for medicine and food clearly stipulated by the Ministry of Health. It is rich in nutrients such as sugar, protein and vitamins. Polygonatum likes a cool and humid environment, and is often found in the undergrowth, bushes or shaded hillsides. Due to the improvement of people's economic level and living standard, people begin to pay more attention to health and health preservation, so the wild resources of medicinal plants such as sealwort are becoming more and more scarce. In order to effectively protect the wild resources of medicinal plants and meet people's demand for medicinal products, the artificial cultivation of medicinal plants has become an import...
