Problems solved by technology

But at present the cultivation technology of blue skyflower is to propagate with bulbs, and the bulbs only grow once a year, and only grow one leaf, and the growth time generally only has six months (from March to August of that year), and the bulbs are in a dormant state at other times. There is no literature report on how to promote the growth of leaf buds in the bulbs of the blue skyflower during the growth period

Embodiment 1

[0031] The Method of Promoting the Long Leaf Buds of the Corm

[0032] 1. The preliminary treatment of the bulb of blue skyflower

[0033] Dig out the bulbs of blue skyflower that are in a dormant state and have full bulbs without mold spots or black spots from the wild or the substrate of cultivated blue skyflower, wash off the sediment on the bulbs with tap water, dry them, and dry the skin of the bulbs slightly without water;

[0034] 2. Prepare a kinetin solution with a concentration of 10ppm

[0035] The preparation method is to take the kinetin powder stored at -20°C, accurately weigh 0.01g and pour it into a test tube, then add 2ml of ethanol with a volume concentration of 95% to dissolve, and after the kinetin is completely dissolved, prepare the concentration with distilled water or pure water. 10ppm kinetin solution;

[0036] 3. Bulb Soaking

[0037] Soak the blue skyflower bulbs treated in step 1 into the kinetin solution prepared in step 2. The kinetin solution ...

Embodiment 2

[0045] The method to promote the long leaf buds of the blue skyflower corm:

[0046] 1. The preliminary treatment of the bulb of blue skyflower

[0047] Same as step 1 of embodiment 1

[0048] 2. Prepare kinetin solutions with different concentrations

[0049] The preparation method is to take the kinetin powder stored at -20°C, accurately weigh 0.01g and pour it into a test tube, then add 2ml of ethanol with a volume concentration of 95% to dissolve, and after the kinetin is completely dissolved, prepare the concentration with distilled water or pure water. 10ppm kinetin solution, 20ppm, 40ppm and 80ppm kinetin solution concentrations were prepared according to this method;

[0050] 3. Bulb Soaking

[0051] Put the blue skyflower bulbs processed in step 1 into the kinetin solution prepared in step 2 and soak for 30 minutes. The kinetin solution needs to completely soak all the blue skyflower bulbs;

[0052] 4. Bulb culture

[0053] Put the bulbs soaked in step 3 into tra...

Embodiment 3

[0059]The method to promote the long leaf buds of the blue skyflower corm:

[0060] 1. The preliminary treatment of the bulb of blue skyflower

[0061] Same as step 1 of embodiment 1

[0062] 2. Prepare a kinetin solution with a concentration of 10ppm

[0063] Same as step 2 of embodiment 1

[0064] 3. Bulb Soaking

[0065] With embodiment 2 step 3

[0066] 4. Bulb culture

[0067] Same as Step 4 of Example 1, except that the temperature of the incubator is 18°C, 21°C, 25°C, 28°C and 31°C respectively

[0068] 5. Observation of the influence of culture temperature on the long leaf buds of the bulb

[0069] From the test results in Table 3, the growth rate of the long leaf buds of the blue skyflower corm is relatively slow at the culture temperature of 18°C ​​and 21°C, and the probability of long leaf buds after 20 days of cultivation at 21°C is 20%, while at 25°C, 28°C and The probabilities of growing leaf buds at 31°C for 20 days were 60%, 63% and 80% respectively. Th...

Abstract

The invention discloses a method for promoting nervilia fordii corms to grow more leaf buds. The method comprises the following steps: 1, carrying out earlier stage processing on the nervilia fordii corms; 2, preparing a hormone solution with a certain concentration; 3, immersing the corms; 4, cultivating the corms; 5, cutting off buds from the corms which only have one bud; 6, immersing the corms without the buds into the hormone solution; 7, cultivating the corms without the buds; and 8, transplanting. The method has the advantages that the method provided by the invention enables more than 84.8% of the nervilia fordii corms to annually grow two or more than two leaves from a previous condition of annually growing one leaf, so that the annual output and the yield of the unit area of nervilia fordii are improved; a technical support is provided for increasing the output of nervilia fordii medicinal materials and promoting the sustainable development.

Description

technical field [0001] The invention belongs to the fields of agronomy, biology and pharmacy. The invention relates to a method for promoting plant bulbs to grow leaf buds, in particular to a method for promoting blue skyflower bulbs to grow leaf buds. Background technique [0002] Green Skyflower is the dry leaf or bulbous leaf of Nervilia (Nervilia) Nervilia (Nervilia), a plant of the Orchidaceae family (Orchidaceae), which belongs to a small perennial herb. Distributed in Guangxi, Guangdong, Sichuan, Yunnan and other places. Cool in nature and sweet in taste, it has the functions of moistening the lungs and relieving cough, invigorating the spleen and eliminating stagnation, clearing heat and detoxifying, dissipating blood stasis and relieving pain, and mainly treating tuberculosis, cough and hemoptysis, scrofula, bronchitis and other diseases. Due to the large market demand and the fact that the blue skyflower itself reproduces by bulbs, the reproduction rate is extrem...
