Embodiment 1

[0027] Take 1.5kg of hawthorn nucleus, jujube nucleus and walnut shell respectively, add it to the retort at a mass ratio of 1:1:1, heat to 140~145℃, keep for 1 hour, continue to heat to 240~245℃, keep for 2 hours, then The temperature rose to 300-360°C for 1 hour. Collect the dry distillate in each period, mix and stir for 30 minutes, transfer to a separatory funnel and let stand for 12 hours, and separate the supernatant. The supernatant was added to the distillation pot, distilled at 100-105°C for 2 hours, and the distillate was collected. Add 10wt% activated carbon to the distillate, stir and heat to 95°C, maintain for 45 minutes, filter, and collect the filtrate. The filtrate is the plant growth regulator of the present invention, and can also be referred to as plant dry distillate, the same below.

Embodiment 2

[0029] Take the hawthorn nucleus, jujube nucleus and walnut shell total 1.5kg, the mass ratio is 6:2:3 into the dry distillation kettle, heat to 140~145℃, keep for 1 hour, continue to heat to 240~245℃, keep for 2 hours, then temperature Raise to 300~360℃ for 1 hour. Collect the dry distillate in each period, mix and stir for 30 minutes, transfer to a separatory funnel and let stand for 12 hours, and separate the supernatant. The supernatant was added to the distillation kettle, distilled at 100-105°C for 2 hours, and the distilled liquid was collected. Add 10wt% activated carbon to the distillate, stir and heat to 95°C, maintain for 45 minutes, filter, and collect the filtrate. The filtrate is the plant growth regulator of the present invention.

Embodiment 3

[0031] Take the hawthorn nucleus, jujube nucleus and walnut shell totaling 1.5kg, the mass ratio is 11:2:2 into the retort, heat to 140~145℃, keep for 1 hour, continue to heat to 240~245℃, keep for 2 hours, then temperature Raise to 300~360℃ for 1 hour. Collect the dry distillate in each period, mix and stir for 30 minutes, transfer to a separatory funnel and let stand for 12 hours, and separate the supernatant. The supernatant was added to the distillation kettle, distilled at 100-105°C for 2 hours, and the distilled liquid was collected. Add 10wt% activated carbon to the distillate, stir and heat to 95°C, maintain for 45 minutes, filter, and collect the filtrate. The filtrate is the plant growth regulator of the present invention.

Abstract

The invention discloses a method for promoting the germination of Astragalus seeds. The steps are: before the seeds germinate, the Astragalus seeds are pretreated with a plant growth regulator, and the plant growth regulator has a mass ratio of 1-13:1- 2:1-3 The dry distillation solution obtained by dry distillation of hawthorn core, wild jujube core and walnut shell. The invention adopts plant retort liquid as a plant growth regulator to pretreat astragalus seeds. The pretreatment method is simple, easy to operate, and pollution-free, can significantly increase the germination rate of astragalus seeds, and has high economic benefits. In addition, the plant dry distillation liquid used is the dry distillation liquid obtained by dry distillation of the cores and shells of three plants: hawthorn core, walnut shell, and wild jujube core. The preparation method is simple, concise, fast, and easy to implement. The waste is fully utilized, the waste is turned into wealth, the cost is low, and the industrial production is convenient.

Description

Technical field [0001] The invention relates to a method for promoting the germination of Astragalus seeds, in particular to a method for promoting the germination of Astragalus seeds by using dry distillate extracted from plants, and belongs to the technical field of seed treatment. Background technique [0002] With the emergence of the "return to nature" trend, traditional natural botanicals are becoming more and more popular. Astragalus is derived from the dry roots of legumes Astragalus membranaceus (Fisch.) Bge.Var.Mongholicus (Bge.) Hsiao or Astragalus membranaceus (Fisch.) Bge. It has the functions of diuresis, swelling, soreness and muscle growth, etc., which are commonly used in my country. At present, with the increasing demand for Astragalus medicinal materials in the domestic and foreign markets, it has triggered over-excavation of wild resources. Wild Astragalus can no longer meet the market demand, and artificial cultivation of Astragalus has been paid more attenti...
