Problems solved by technology

But traditional cinnamon seed propagation has the following defects: (1) cinnamon seed resources are in short supply, expensive, and difficult to collect in batches; (2) the seed germination rate is low, generally only reaching about 80%; (3) the germination time is long, generally 20 -50 days
Cutting propagation is to take a part of the vegetative organs of the plant, insert it into loose and moist soil or fine sand, and use its regeneration ability to make it take root and branch to become a new plant. The existing problems are: (1) The survival rate of cutting propagation is low , the rooting time of cuttings is long; (2) cutting resources are in short supply, and it is difficult to reproduce in batches
At present, the problems in the propagation technology of cinnamon seedlings have seriously hindered the large-scale production of cinnamon, and thus cannot meet the market demand for cinnamon. It is necessary to establish a method that can reproduce cinnamon seedlings in large quantities and quickly.

Embodiment 1

[0034] 1. Raw material preparation:

[0035] Seedling-raising matrix is ​​prepared by the following specific methods:

[0036] S1. Activation pretreatment of EM bacteria: Peel the potatoes, slice them, dry them in the sun, and crush them. While adding potato flour to the conical flask, spray water from the inlet of the conical flask into the conical flask. The weight of potato flour and water The ratio is 1:10, then boiled in a boiling water bath for 3 hours, then filtered to get the filtrate, then the filtrate was centrifuged at 3000rpm for 2 minutes, the supernatant was taken, and then concentrated to a concentration of 30 ° of Pomi solution, and then pour the ethanol solution with a mass fraction of 75% into it while pouring and stirring, and then produce a large amount of flocculent precipitate, then freeze at a temperature of -2°C for 5 hours, then reduce the pressure to 120 Pa, and the temperature is at 26°C After drying for 10 hours, the potato polysaccharide can be ob...

Abstract

The invention belongs to the technical field of plantation, and especially relates to a method for improving the qualified seedling rate of Cinnamomum cassia Presl seedlings. The method concretely comprises the following steps: (1) seed screening; (2) seed sowing; (3) seedling growth management; and (4) coming out of a nursery: selection of seedlings having a height of 40-50 cm and a rhizome sizeof 0.05 cm or more, transplantation of the seedlings with the growth cycle of two years preferably in the last ten-day period of every March, and timely rooting water spraying after the transplantation. The method adopts seed propagation to increase the germination rate of Cinnamomum cassia Presl, a seedling cultivation substrate suitable for the growth of Cinnamomum cassia Presl is adopted to cultivate, and the seedling management improves the qualified seedling rate of Cinnamomum cassia Presl seedlings in order to achieve large-scale reproduction of the Cinnamomum cassia Presl seedlings.

Description

【Technical field】 [0001] The invention belongs to the technical field of planting, and in particular relates to a method for improving the emergence rate of cinnamon seedlings. 【Background technique】 [0002] Cinnamon (Cinnamomum cassia Presl.), an evergreen tree belonging to the family Lauraceae, also known as cinnamon bark, cinnamon bark, cinnamon bark, cinnamon osmanthus, Qibian laurel, osmanthus osmanthus, eucalyptus bark, tube laurel, and official laurel, is a commonly used traditional Chinese medicine in my country. species of wood. It is mainly produced in Guangdong, Guangxi, Yunnan, Hainan, Fujian, Zhejiang, Hunan, Jiangxi, Sichuan and other provinces and regions, among which Guangdong and Guangxi are the largest producing areas of cinnamon in my country, accounting for more than 95% of the country's output. Cinnamon is pungent and hot, and its bark, branches, flowers, fruits and roots can be used as medicine. Cinnamon bark has the functions of warming the kidney an...
