A method for regulating the flowering period of bletilla striata
A Bletilla striata flower-promoting technology, which is applied in the field of plant cultivation, can solve the problems that there is no method for regulating the flowering period of Bletilla striata, and it is unfavorable for the promotion of Bletilla striata, and achieve the effects of promoting normal germination and growth, saving production costs and procedures, and simple control process

Embodiment 1
[0021] Embodiment 1: low temperature treatment temperature screening embodiment
[0022] Bletilla striata bulb selection: Select 400 bletilla striata bulbs with consistent growth and robust growth in the bletilla striata nursery, carefully subtract the roots, stems and leaves with scissors, clean them, dry them naturally and weigh them, and select 25-35g bletilla striata bulbs from them.
[0023] The bletilla striata bulb of selection is carried out to following low-temperature treatment:
[0024] Test method: Set the temperature at 0, 5, 8, and 10°C respectively, treat 100 bulbs at each temperature, and count the germination rate after one month of treatment.
[0025] Test results: As shown in Table 1, the germination rate of Bletilla striata was the highest at 5°C, reaching 86%, so it was concluded that the optimum temperature for Bletilla striata bulbs to be treated at low temperature was 5°C.

Embodiment 2
[0028] Embodiment 2: low temperature processing time screening embodiment
[0029] Bletilla striata bulb selection: Select 200 bletilla striata bulbs with consistent growth and robust growth in the bletilla striata nursery, carefully subtract the roots, stems and leaves with scissors, clean them, dry them naturally and weigh them, and select 25-35g bletilla striata bulbs from them.
[0030] The selected bletilla striata bulbs were subjected to the following low-temperature treatment.
[0031] Test method: Bletilla striata bulbs were moved into an artificial climate chamber for low-temperature treatment at a temperature of 5°C and a humidity of 70% in a dark environment for 15 days, 20 days, 30 days, 35 days, and 40 days, respectively. Bletilla striata without low-temperature treatment was used as a control. After the treatment, it was moved into another artificial climate box, and the seedling slowing treatment and flowering treatment were carried out successively, and the ger...
Embodiment 3
[0036] Example 3: Screening Example of Foliar Application of Fertilizers During Flower Urgent Treatment
[0037] 1. Digging seedlings: Select 200 bletilla striata in the bletilla striata nursery that grows consistently and grows robustly. Use scissors to carefully subtract the roots, stems and leaves, clean them, dry them naturally, and weigh them. Select 25-35g bletilla striata bulbs from them.
[0038] 2. Low temperature treatment: place the Bletilla striata bulbs selected in step 1 in an artificial climate box, set the temperature to 5°C, humidity to 75%, light intensity 0Lx, and dark treatment for 25 days.
[0039] 3. Planting: Evenly mix the garden soil and vermiculite at a ratio of 1:3, pour it into a seedling cup, the depth of the soil layer is about 5cm, and then bury the bulb buds upwards in the substrate, and finally water thoroughly.
[0040] 4. Slow seedling treatment: After planting, first undergo 10 days of slow seedling treatment, respectively set the daytime li...
