Problems solved by technology

The main propagation method of Boluohui is seed propagation, but the biggest problem in seed propagation is that the germination rate of Boluohui seeds is not high under natural conditions, between 20% and 35%, and it is difficult to carry out large-scale artificial cultivation

Embodiment 1

[0036] (1) The collected Boluohui seeds are washed with warm water, and the mature seeds with full particles are selected and rinsed with clear water after being treated with concentrated hydrochloric acid for 25 minutes;

[0037] (2) soak the Boluo seeds that step (1) has processed with 2.0mg / L cytokinin 6-BA for 3h;

[0038] (3) Rinse the Boluo seed water that has been processed in step (2) for 30min, soak the seeds with 500mg / L gibberellin and 50mg / L polyethylene glycol mixed solution for 24h, and then take out the moisture on the surface of the dried seeds; then Boluohui seeds and river sand are mixed evenly at a ratio of 1:4, then put into a mesh bag, and the mesh bag is covered with river sand by 4.5cm for sand storage for 20 days;

[0039] (4) In the middle of March of the second year, the Boluohui seeds after the sand storage treatment were cultivated and germinated in the light incubator (24° C. of temperature, 60% humidity), and the growth rate of the Boluohui seeds ...

Embodiment 2

[0041](1) The collected Boluohui seeds are washed with warm water, and the mature seeds with full particles are selected and rinsed with clear water after being treated with concentrated hydrochloric acid for 15 minutes;

[0042] (2) soak the Boluo seeds that have been processed in step (1) with 2.0mg / L cytokinin 6-BA for 1.5h;

[0043] (3) Rinse the Boluo seed water that has been processed in step (2) for 20min, soak the seeds with 300mg / L gibberellin and 40mg / L polyethylene glycol mixed solution for 36h, and then take out the moisture on the surface of the dried seeds; then Boluohui seeds and river sand are mixed evenly at a ratio of 1:4 and put into a mesh bag, and the mesh bag is covered with river sand by 2.5cm for sand storage for 30 days;

Abstract

The invention provides a method for improving the germination rate of macleaya cordata seeds. The method comprises the following steps: treating the macleaya cordata seeds with an exogenous reagent, and carrying out cultivation and germination on a cultivation medium after stratification and lamination, wherein the exogenous reagent is a mixed solution of concentrated hydrochloric acid, cytokinin,gibberellin and polyethylene glycol in sequence. The method provided by the invention can remarkably promote germination of the macleaya cordata seeds, the germination rate is improved to 75-80% andis improved by nearly 3 times, artificial cultivation of the macleaya cordata seeds is facilitated, and the cultivation cost is greatly saved.

Description

technical field [0001] The invention relates to the technical field of cultivation of Chinese medicinal materials, in particular to a method for improving the germination rate of Boluohui seeds. Background technique [0002] Macleaya cordata is a perennial erect herbaceous plant belonging to the Papaveraceae plant. The whole column is highly poisonous. The whole plant can be used as medicine, but it cannot be taken internally. It is often used to treat rheumatic bone disease, bruises and swelling, mosquito bites, Skin itching and acne, etc., the curative effect is remarkable. At present, in clinical medical treatment and pesticide production, there is a great demand for Boluohui. Boluohui mainly grows in hills, forests, grass and shrubs at 150-830 meters. It likes a warm and humid growth environment. It is cold-resistant and drought-tolerant. It does not have high requirements for soil, but it has a better planting effect in fertile soil. The main propagation method of Bol...
