Problems solved by technology

Existing rhizome propagation is adopted, the variety update speed is slow, and it is susceptible to viral diseases, and the variety degrades seriously after multi-generation breeding; at the same time, the amount of species used is large, and a large amount of wild sealwort needs to be excavated, which seriously damages the source of provenance and the environment; while the existing Adopt seed propagation, there is growth period long, the problem such as seed germination, seedling rate is low, therefore provide a kind of can improve the seed germination rate and the seedling rate of Rhizoma Polygonatum, shorten the cultivation method of Rhizoma Polygonatum seedling of whole seedling cycle is very necessary

preparation example Construction

[0024] The preparation method of described mixed plant layer comprises the following steps:

[0025] A. First dry castor leaves, tripterygium leaves, waste tobacco leaves, and wolfberry leaves to a water content of 10-20%;

[0026] 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;

[0027] C. Cut the bark of Tripterygium wilfordii and Nanshan rattan 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.

[0028] The seedling raising substrate described in step (3) 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.

Embodiment 1

[0030] A method for cultivating Polygonatum seedlings, comprising the following steps:

[0031] 1) Seed collection and storage: Collect mature Polygonatum fruits in mid-October, take out the seeds and select Polygonatum seeds with high plumpness, no insects, no diseases, and a diameter of 0.22 cm; 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 hand, touches and is promptly scattered as degree, then digs a pit at the outdoor leeward place, and the sealwort seed and wet sand The mixture can be buried;

[0032] The pit depth of described digging pit is 30cm, and there is isolation layer at the bottom of described pit; Described isolation layer comprises the vermiculite layer of the lowest 2cm, is laid on the sand bed that thickness is 3cm above the vermiculite layer, and lays A layer of mixed vegetation with a thickness of 4 cm above the sand lay...

Abstract

The invention discloses a method for cultivating rhizoma polygonati seedlings. The method for cultivating the rhizoma polygonati seedlings includes the step (1) of seed collection and storage; the step (2) of seed germination, and the step (3) seedling cultivation. The method for cultivating the seedlings is high in seed germination rate and seedling rate, effectively shortens the entire seedlingculture period, reduces cost, has high benefit, and is convenient for expansion and promotion. Rhizoma polygonati seeds are mixed with sand for storage, and water absorption obstacles of the rhizoma polygonati seeds are alleviated, thereby effectively breaking the dormancy. Further, during outdoor storage, first an isolation layer is arranged, so that certain wettability can be maintained while the accumulation of water in the storage position is effectively prevented, and the dormancy breaking efficiency is greatly improved. An arranged mixed plant layer does not rot easily after being driedand rubbed. Under the immersion of rainwater and the like, on the one hand, plant-derived materials released can repel pests in the soil, and on the other hand, the plant-derived materials released can avoid seed mildew to a certain extent.

Description

technical field [0001] The invention belongs to the technical field of plant planting, and in particular relates to a method for cultivating Polygonatum seedlings. Background technique [0002] Polygonatum, also known as: Chicken Head Polygonatum, Yellow Chicken Vegetable, and Chicken Claw Ginseng; it is a plant of the genus Polygonatum, which has the effects of nourishing the spleen, nourishing the lungs, promoting body fluid, nourishing qi and nourishing yin, antibacterial, anti-aging, beautiful appearance, and strong energy. For weak spleen and stomach, fatigue, fatigue, dry mouth, lack of food, insufficient blood, high blood pressure and other diseases, external use of 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 Polygonatum, is famous both at home and abroad for its good taste, quality and curative ...
