Problems solved by technology

Due to the difficulty in collecting the seeds of Rhizoma Polygonatum, the germination rate is low, and the growth cycle of seedlings is long, which increases the cost of production and planting, which is not conducive to the promotion of planting in large areas.
The method of rhizome propagation has a low reproduction coefficient, and the large amount of rhizomes used is not economical, but also limits the scale of production and planting. The problem of seedlings has become a bottleneck restricting the large-scale artificial planting of Rhizoma Polygonatum.
At present, the field intensive planting technology for Polygonatum yunnanensis is not perfect, and most of them are planted in small quantities by growers, with a low degree of intensification

Embodiment 1

[0076] A method for intensive planting of Polygonatum yunnanensis in the field, comprising two steps of seedling raising and intensive planting, the seedling raising method adopts seed seedling raising, and the method for seed seedling raising includes the following steps:

[0077] S1. Seed selection and treatment: From late September to late October, collect the reddish and ripe fruits of Rhizoma Polygonatum, spread them on the bamboo fence, and place them in a cool and well-ventilated place for 10-20 days; wait until the surface of the berries is dehydrated shrunken, soaked in water, removed the pulp, took out the seeds, soaked in 1% to 2% carbendazim solution for 2 to 2.5 hours, took out the seeds and drained until the surface was dry, then spread them on the sand bed for germination. Cover the river sand with a thickness of about 1cm to keep the river sand moist;

[0078] S2, the preparation of seedling-raising substrate: fully mix the decomposed farmyard manure, peat, cak...

Embodiment 2

[0120] The same steps of this embodiment and embodiment 1 will not be repeated, and the different steps are:

[0121] The gibberellin spraying concentration of 0.5%~1.5% before sowing in the nursery in the present embodiment, the spraying density is 100ml / m 2 , and then spray the concentration of 0.5% to 1.5% of naphthalene acetic acid, and the spraying density is 100ml / m 2 .

[0122] The step (7) of the field intensive planting method in the present embodiment is to install the device for releasing water and fertilizing:

[0123] Install a row of water release and fertilization devices on each furrow surface. In the same row, two adjacent water release and fertilization devices are connected with water pipes, with an interval of 0.8 to 1.2m;

[0124] (8) Field management

[0125] Water management: After transplanting, pour 2000-3000ml of irrigation water into each water release and fertilization device every 10-15 days to keep the soil moist, and prepare for clearing ditch...

Embodiment 3

[0129] From late September to late October, select mature and plump seeds for immediate sand storage: 1 part of seed and 3 parts of sand are mixed evenly; store in a 30 cm deep pit in the shade and keep it moist; wait until late March of the next year to sieve After the seeds are produced, spread them evenly in the shallow ditch on the furrow surface with a row spacing of 12-15 cm, cover with soil about 1.5 cm, water after a little pressure, and cover with a layer of grass to keep moisture; remove the cover grass before emergence, and the height of the seedlings is 6-9 cm When it is too dense, the seedlings can be thinned appropriately, and transplanted after 1 year.

[0130] The soil preparation was carried out according to the conventional method, the seedlings obtained in this example were transplanted into the planting site according to the conventional method, and the field management was carried out according to the conventional method.

[0131] The various parameters of...

Abstract

The invention discloses a field intensive planting method of Polygonatum kingianum Coll.et Hemsl. The field intensive planting method comprises two steps of seedling-raising and intensive planting, wherein the seedling-raising method adopts seed seedling-raising or rhizome seedling-raising, and the method of seed seedling-raising comprises the following steps: S1, seed selection and treatment; S2,preparation of a seedling-raising substrate; S3, nursery design; S4, nursery disinfection; S5, sowing; and S6, nursery management. In the field intensive planting method, the seedling-raising substrate is combined with a plant growth regulator, a seedling-raising cycle of Polygonatum kingianum Coll.et Hemsl is greatly shortened, and the field intensive planting method realizes large-scale planting of Polygonatum kingianum Coll.et Hemsl, and reduces the labor cost of large-scale planting of Polygonatum kingianum Coll.et Hemsl.

Description

technical field [0001] The invention relates to the technical field of planting medicinal plants, in particular to a field-intensive planting method of Polygonatum yunnanensis. Background technique [0002] Polygonatum kingianum Coll. et Hemsl is a herbaceous plant of Polygonatum kingianum Coll. et Hemsl, whose rhizome is nearly cylindrical or nearly bead-shaped, and the nodules are sometimes irregularly diamond-shaped and hypertrophic. Berries red, 1-1.5 cm in diameter, with 7-12 seeds. The flowering period is March-May, and the fruiting period is September-October. According to the "Chinese Pharmacopoeia" 2015 edition, the traditional Chinese medicine Polygonatum Polygonatum is the dried rhizome of Polygonatum Polygonatum, Polygonatum Polygonatum or Polygonatum Polyflora. Polygonatum Polygonatum is one of the basic varieties of Polygonatum, its rhizome is relatively thick, and it is one of the best quality varieties of Polygonatum medicinal materials. Dian Huang Jing is...
