Problems solved by technology

The above process takes a long time and the steps are cumbersome and complicated. It is necessary to spray the mixed solution of potassium dihydrogen phosphate and gibberellin from the flowering stage of the mother plant, otherwise the germination effect of directly using gibberellin EC to soak the seeds is not good
In addition, in the actual production process, Ainaxiang seeds are often purchased, and it is not possible to spray the mixed solution of potassium dihydrogen phosphate and gibberellin on the flowering stage of the mother plant in advance.

Embodiment 1

[0039] Ainaxiang seed treatment method

[0040] (1) Configure 1000mg / L GA3 aqueous solution;

[0041] (2) Heating the solution to 40°C and maintaining a constant temperature;

[0042] (3) Completely immerse the Ainaxiang seeds (1000 grains) stored in the refrigerator at 4°C in the above solution, and keep the temperature at 40°C for 6 hours;

[0043] (4) Lay filter paper on the test bench, place the Ainaxiang after soaking on the filter paper, and dry in the shade;

[0044] (5) Spread the above-treated seeds evenly in the field of the experimental base of Guangdong Institute of Traditional Chinese Medicine, and evenly cover with 0.5-1cm of fine yellow loam;

[0045] (6) Because the seeds are small, in order to prevent the seeds from being washed away by rainwater, a sunshade net is covered on the seedbed;

[0046] (7) Spray water once every morning and evening to keep the seedbed moist (relative humidity is about 80%);

[0047] (8) One week after sowing, the Aina seedlings...

Embodiment 2

[0050] The difference between this embodiment and embodiment 1 is that the concentration of the GA3 aqueous solution is 800 mg / L, and the others are consistent with embodiment 1.

Embodiment 3

[0052] The difference between this embodiment and embodiment 1 is that the concentration of the GA3 aqueous solution is 1200 mg / L, and the others are consistent with embodiment 1.

Abstract

The invention relates to a method for increasing the germination rate of blumea balsamifera seeds. The method comprises the following steps of soaking the blumea balsamifera seeds in a gibberellin aqueous solution, wherein the temperature of the gibberellin aqueous solution is 30-45 DEG C, and the concentration of the gibberellin aqueous solution ranges from 800 mg / L to 1200 mg / L. By means of themethod, dormancy of the blumea balsamifera seeds can be efficiently relieved, germination of the blumea balsamifera seeds is promoted, and the germination rate of the blumea balsamifera seeds is remarkably increased.

Description

technical field [0001] The invention relates to the field of agricultural technology, in particular to a method for improving the germination rate of Ainaxiang seeds. Background technique [0002] Ainaxiang is one of the important national medicines in my country. It is used as medicine with dried stems and leaves, and it is also one of the raw materials for extracting natural borneol. But, because the germination rate of Ainaxiang seed is extremely low (about 5%), therefore, the main mode of propagation is asexual reproduction at present. However, there are many difficult problems in the actual production of asexual reproduction, such as the low survival rate of transplanting and the easy carrying of viruses in meristems. Studies have shown that although the germination rate of Ainaxiang seeds is extremely low, some seeds can still germinate, which fully demonstrates the advantages and utilization value of the sexual generation. Therefore, how to improve the germination r...
