How to make vanilla blossom ahead of time? How to make vanilla blossom ahead of time

Vanilla flowers in winter and spring. In the process of growth, if the temperature is artificially controlled, it can bloom in advance. So, how to make vanilla blossom ahead of time? The following is the method that Uncle Gardener introduced to make Shetland blossom ahead of schedule. Disinfection of Shellfish 1 Seed Bulbs In early summer, the seed bulbs enter a dormant period, and after all the aboveground parts wither, the seed bulbs are dug out. Soak in chlorothalonil 2000 times solution for 30 minutes, sterilize, dry in the shade, and then store in 10. 2. High temperature treatment in summer, when the temperature is high, vanilla will enter the dormant period. If you want to blossom early, put the seed ball in a high temperature environment to break its dormancy period. It can be released by smoking or ethylene. Ceylon 3. When sowing deep-buried sawdust in spring, wet sawdust is used as medium, mixed with a small amount of soil, and seed balls are deeply buried in it. Spray water frequently to keep sawdust moist. Promote rooting and germination in the vernalization process, and blossom in the second year without too much treatment, and naturally bloom earlier. 4. Controlling temperature is the most direct and meticulous method. The cold storage process of seeds is also the differentiation process of flower buds. Therefore, the time and temperature of refrigeration should be strictly controlled. If it is required to bloom in June 1 1, it needs to be refrigerated in 10 for 40-50 days and planted in the middle and late September; If it blooms in June 5438+February, it needs to be refrigerated for 30 to 40 days; Flowers bloom on New Year's Day, only need to be refrigerated for 30 days, and planted in June165438+1October. After planting, the temperature before flowering should be controlled at 15. In fact, the shorter the storage days, the later the flowering time, but the range of refrigeration is 30~50 days. Beyond this range, the growth of plants will be inhibited, with little or no flowering. The results showed that the bulb of vanilla could promote rooting and germination in 13.5~ 15. Flower bud differentiation requires a low temperature of 8~ 13. The suitable temperature for flower bud development is 13~ 18. Under 18, flowering will be delayed and flower stems will be shortened. Higher temperature can promote early flowering, but plant growth is weak. Vanilla can promote flower bud differentiation in short sunlight. However, after flower bud differentiation, long sunshine will lead to early flowering. Bulbs are usually sown in September, and flower buds begin to differentiate at the beginning of 165438+ 10, and the differentiation is completed at the end of 165438+ 10. After May of the following year, the leaves gradually withered and the bulbs entered a natural dormancy period.
