Netizens asked: why didn't eight or nine orchids blossom after three or four years? I see

Netizens left me a message on Baijia platform, saying that his more than ten pots of orchids had not bloomed after growing them for four years. First of all, rule out the possibility that the orchid is not mature and does not blossom. At the same time, it is impossible to pick so many orchids in the same place, so we also rule out the example that the farmer said before: Yinshan seedlings.

Netizens should have no problem with the preparation of plant materials, which is 75% pine bark, 15% humus soil, and 10% volcanic stone. With both hardware and software, Langen should also be well developed. So, why not blossom?

I think he should sort it out from these aspects:

First, from the photos he sent me, I can see that Lan Ye is a little under-fat, and his plant material has not been changed in three or four years. The nutrients in the plant have been exhausted in recent years, orchid flowering is very energy-consuming, if the nutrients in the plant can not keep up, it must be artificially replenished. It is suggested that some organic fertilizer or ternary compound fertilizer should be applied. If it is three or four years ago, the old plant material should be changed, when changing the plant material can be mixed with mature organic fertilizer, combined with foliar spraying nitrogen, phosphorus and potassium balanced foliar fertilizer.

Second, his plant material has a relative proportion of more than 75%. The advantage of this kind of plant material is that it is convenient to water, and this kind of plant material is commonly used in large orchid farms. Can often be served by heavy water, which will make the environment and basin soil humidity is very high, and too much humidity will also affect flower bud differentiation, will only always grow leaf buds, thus dispersing the energy needed for budding, flower bud germination will be suppressed.

Third, here comes the most important point, circle it with a pen (for the key Hong Kong Certificate of Education examination). Orchids can blossom only after a long period of vernalization of low temperature (between 2 and 10 degrees) and a temperature difference of more than 15 degrees between day and night. Without these climatic conditions, it is also possible to create a small environment. So good farmers often say: temperature and temperature difference are necessary conditions for orchids to blossom and produce good flowers.
