Embodiment 1

[0040] A greenhouse cultivation method for Polygonatum seedlings, comprising the steps of:

[0041] 1) In October-November every year, pick the ripe Polygonatum fruit;

[0042] 2) Spread the Polygonatum fruit obtained in step 1) on the dry ground, and dry it at room temperature until the pericarp of the Polygonatum fruit is wrinkled, and when the water content of the Polygonatum fruit is lower than 50%, use air permeability Put it in a good plastic bag, store it in a dry room with a temperature above 20°C, and store it for later use.

[0043] 3) Prepare humus, Bordeaux mixture or carbendazim solution, and spray and disinfect the humus according to the ratio of 1000kg humus, 20kg Bordeaux mixture or 20kg carbendazim solution; wherein, Bordeaux mixture is copper sulfate, quicklime and water According to the mass ratio of 1:3:300 to mix the mixed solution evenly, the carbendazim solution is 1200 times the carbendazim solution;

[0044] 4) by step 3) the humus after the disinfec...

Embodiment 2

[0053] Present embodiment is on the basis of embodiment 1, step 4) the phosphorus content of the phosphate fertilizer that adopts ≥ 38%, nitrogen, phosphorus, potassium three content ≥ 48% in the compound fertilizer, and potassium content ≥ 8% in the compound fertilizer, This setting ensures the nutritional requirements of the Polygonatum seedlings on nitrogen, phosphorus and potassium during the cultivation process in the greenhouse, and ensures the yield and quality of the Polygonatum seedlings.

Embodiment 3

[0055] In this embodiment, on the basis of embodiment 1 or embodiment 2, the film described in step 5) is a polyvinyl chloride plastic film, and the fermentation temperature is 15-25 ° C. This setting is conducive to the composition of humus soil, phosphate fertilizer and compound fertilizer The nutrient matrix contains less miscellaneous bacteria and insect eggs, which further reduces the damage of diseases and insect pests, and it is fermented at room temperature without destroying the nutrients in the nutrient matrix. The use of polyvinyl chloride plastic film is easy to obtain and low cost; thereby ensuring the protection of Polygonatum species The yield per mu of seedlings and reduce the cultivation cost of Polygonatum seedlings.

Abstract

The invention discloses a method for cultivating rhizoma polygonati seedlings in greenhouses. The method includes steps of 1), picking ripe rhizoma polygonati fruits; 2), drying the ripe rhizoma polygonati fruits; 3), disinfecting humus soil; 4), preparing mixed media; 5), preparing nutrient media; 6), carrying out cultivating and reproducing by the aid of nutrition cups; 7), planting the rhizoma polygonati fruits in the greenhouses at the internal temperatures of 22-25 DEG C under the control, keeping the greenhouses ventilated, illuminating the rhizoma polygonati fruits for the illumination time of 10-15 hours/day, regularly spraying disinfectant liquid, regularly spraying clear water after the rhizoma polygonati seedlings emerge and illuminating the rhizoma polygonati seedlings for the prolonged illumination time of 15-20 hours/day; 8), only reserving a strong rhizoma polygonati seedling in each nutrition cup when the rhizoma polygonati seedling grows and the height of the rhizoma polygonati seedling reaches 2.5-3.5 cm, and irrigating the roots of the rhizoma polygonati seedlings with potassium fertilizer water with the proportion of 80-150 times before the rhizoma polygonati seedlings are transplanted; 9), transplanting the rhizoma polygonati seedlings. The method for cultivating the rhizoma polygonati seedlings in the greenhouses has the advantages of high reproduction sprouting rate, high survival rate after emergency of the seedlings, few seedlings without rhizomes after emergency of the seedlings, few plant diseases and insect pests, high growth weights of rhizomes of individual plants, short growth cycle and convenience in transportation.

Description

technical field [0001] The invention belongs to the technical field of artificial planting of medicinal plants, and in particular relates to a method for cultivating Polygonatum seedlings in a greenhouse. Background technique [0002] Polygonatum sibiricum belongs to the genus Polygonatum sibiricum in Liliaceae, and it is mainly distributed in Hebei, Shanxi, Shaanxi, Inner Mongolia and other places in my country. Under normal conditions, its wild resources are mainly distributed in forests, shrubs or hillside shade, at an altitude of 800-2800 meters. [0003] In "Flora of China", there are 31 species of Polygonatum genus recorded in my country, with a wide geographical distribution, but only three species of Polygonatum, Polygonatum multiflora and Polygonatum yunnanensis are included in the 2015 Pharmacopoeia. Polygonatum rhizome is used as medicine, mainly containing niacin, quinones, starch and polysaccharides and other components. Polygonatum is flat in nature and sweet...
