Problems solved by technology

The existing cultivation technology is not perfect, and there are widespread phenomena such as excessive fertilization and abuse of herbicides, which make the heavy metal content and pesticide residues of some Polygonatum medicinal materials exceed the standard, which in turn affects the output and quality of Polygonatum medicinal materials. It is difficult to obtain the recognition of the international market. Limit the application of Polygonatum

preparation example Construction

[0037] The preparation method of described mixed plant layer comprises the following steps:

[0038] A. First dry castor leaves, tripterygium leaves, waste tobacco leaves, and wolfberry leaves to a water content of 10-20%;

[0039] B. Then manually knead the raw materials that have been dried in step A for 5-10 minutes until they can be held together and the leaves are not broken;

[0040] C. Cut tripterygium twig bark and Nanshan rattan bark into 1-2cm sections, then mix them into the raw materials treated in step B, and dry them in the shade at a room temperature of 15-20°C for 8-14 hours.

[0041] The seedling-raising substrate described in the step (2) includes the following raw materials in parts by weight: 3-5 parts of humus, 1-2 parts of river sand, and 1-2 parts of coconut peat.

[0042] The preparation method of the farmyard manure described in the step (4) is to fully stir the cow dung and sheep dung evenly, and then pile up and ferment and decompose. The decomposin...

Embodiment 1

[0048] A method for imitating wild cultivation of Polygonatum, comprising the following steps:

[0049] 1) Site selection: Select a sandy loam forest land with convenient drainage and irrigation, deep soil layer, and planted with Yunnan pine. The shading degree of the forest land is 70%, and then the land under the forest is prepared, dead branches are removed, and the soil is deeply plowed , then leveled, steam sterilized, and then made a planting bed, the width of the planting bed is 1.2cm, and the length is determined according to the forest conditions;

[0050] 2) Seedling cultivation:

[0051] A. Seed collection and storage: Collect mature Polygonatum fruit in mid-October, take out the seeds and select Polygonatum seeds with high plumpness, no insects, no diseases and a diameter of 0.22cm; then mix the selected Polygonatum seeds with wet sand Evenly, the weight ratio of described Polygonatum seed and wet sand is 1:3, and described wet sand is held into a ball with the ha...

Abstract

The invention discloses a method for imitation wild cultivation of polygonatum. The method for imitation wild cultivation of polygonatum comprises the following steps: 1) land selection; 2) seedling cultivation; 3) seedling transplanting; and 4) field management. According to the method for imitation wild cultivation of polygonatum, a land parcel suitable for the growth of the polygonatum is selected for cultivation, and at the same time, the polygonatum obtained by the imitation wild cultivation under a forest has high yield and good quality, the cost is effective reduced, and the benefit isimproved. At the same time, the method also facilitates enlarged popularization and planting. According to the method for imitation wild cultivation, pesticides and chemical fertilizers are not used,and the quality of the polygonatum is effectively improved. Root irrigation is performed by plant extracts, so that the harm of pests such as grubs to polygonatum seedlings is greatly reduced, the transplanting survival rate is effectively improved, and pests and diseases are reduced further through the arrangement of an insecticidal lamp and a pest-sticking plate.

Description

technical field [0001] The invention belongs to the technical field of plant planting, and in particular relates to a wild imitation cultivation method of Polygonatum. Background technique [0002] Polygonatum, also known as Tiger Ginger and Chicken Head Polygonatum, is the dry rhizome of Polygonatum or Polygonatum, a perennial herb of the family Liliaceae. It has the effects of invigorating the spleen, nourishing the lungs, promoting body fluid, nourishing qi and nourishing yin, antibacterial, anti-aging, beautifying the face, and strengthening energy. It is mainly used for weak spleen and stomach, fatigue, dry mouth, lack of food, dryness of the lung, and insufficient blood. , Meat heat and diabetes, diabetes, high blood pressure embolism, topical sealwort extract can cure athlete's foot. Polygonatum is mainly distributed and cultivated in North China, East China, South China, Central China and other provinces. Yunnan Polygonatum Polygonatum, also known as Sweet Polygonat...
