Embodiment 1

[0034] This embodiment includes the following steps:

[0035] The first step, seedbed selection:

[0036] Choose shady hills at an altitude of 100 meters, choose soil with medium fertility and above (refer to NY / T391-2000 for soil fertility standards), deep soil layer (soil plow layer 35cm), loam soil with a soil pH value of 6-7.5, and the previous stubble The crops are not sweet potatoes, lilies and other crops with underground fleshy roots;

[0037] Seedbeds have good pastoral facilities, excellent irrigation and drainage systems;

[0038] The second step, the production of non-woven planting medium:

[0039] Fully plow the seedbed once in early August, and use glyphosate potassium salt (Monsanto, USA, trade name Damai) once before plowing. According to the number of weeds, use 130ml per mu each time, add 15kg of water and then apply to fully weed. After plowing, apply 100kg of lime per mu, and open drainage ditches to ensure that the soil will not be flooded after plowin...

Embodiment 2

[0056] This embodiment includes the following steps:

[0057] The first step, seedbed selection:

[0058] Choose shady hills at an altitude of 1200 meters, choose soil with medium fertility (refer to NY / T391-2000 for soil fertility standards), deep soil layer (soil plow layer 35cm), and sandy soil with a soil pH value of 6-7.5. Crops with underground fleshy rhizomes such as sweet potatoes and lilies;

[0059] Seedbeds have good pastoral facilities, excellent irrigation and drainage systems;

[0060] The second step, the production of non-woven planting medium:

[0061] Fully plow the seedbed once at the beginning of August, and use glyphosate potassium salt (Monsanto Company of the United States, trade name Damai) twice before plowing. According to the number of weeds, use 200ml per mu each time, and apply after adding 16kg of water to fully weed. After plowing, apply 150kg of lime per mu, and open drainage ditches to ensure that the soil will not be flooded after plowing, ...

Embodiment 3

[0078] In August 2013, the Polygonatum Polygonatum planting technology verification began in the medicinal material base of Shiwu Village, Longtian Town, Ningxiang County. Embed on the spot after planting bagged soil, other conditions are with embodiment 1. A comparative test of conventional planting methods was set up in the same mound field, and planting and field management were carried out according to the traditional planting methods of local farmers. In 2013, large tractors and excavators were used to prepare the land, the seeds were treated on November 12, and the seeds were sown the next day.

[0079] Through verification, it is found that the number of field weeds in the field using the technology of the present invention in 2014 is reduced by more than 50% compared with the conventional planting field. Carry out artificial weeding 7 times altogether on the anniversary of conventional planting, and carry out weeding 3 times altogether on the anniversary of the techno...

Abstract

The invention provides a concentrated seedling culture method for polygonatum odoratum. The concentrated seedling culture method comprises the following steps: step 1, selecting a seedling bed; step 2, manufacturing a non-woven fabric planting culture medium; step 3, selecting seeds and coating seed stems; step 4, sowing the polygonatum odoratum; step 5, carrying out field management of the polygonatum odoratum seedling bed; step 6, preventing and treating diseases and insect pests of the polygonatum odoratum; step 7, transplanting adult seedlings. With the adoption of the concentrated seedling culture method, the cost can be reduced; the resistance capability of the polygonatum odoratum of the first year is enhanced through utilizing the population effect of the polygonatum odoratum, and technical supports are providing for large-scale popularization and planting of the polygonatum odoratum.

Description

technical field [0001] The invention relates to a method for intensive seedling cultivation and planting of Polygonatum odoratum. Background technique [0002] Polygonatum odoratum [Polygonatum odoratum (Mill.) Druce] , Liliaceae Polygonatum is a perennial herb with horizontal rhizomes, yellowish-white flesh, and densely grown fibrous roots. Green leaves, gray below. Flowers axillary, usually in clusters of 1-3. It is cold-resistant and shade-tolerant, and likes a humid environment. It is suitable for growing in loose soil rich in humus. The rhizome of the plant can be used for medicine, and the name of the traditional Chinese medicine is Polygonatum odoratum, which is excavated in autumn. The main cultivated species in Hunan is Xiangyu bamboo, which is mainly produced in Shaodong, Shaoyang, Leiyang, Ningxiang and other places in Hunan. [0003] The traditional production cycle of Polygonatum odoratum is as long as 3.5 years. Usually, the planting field of Polygonatum o...
