How to Improve the Survival Rate of Bletilla striata Planting? Latest Methods Shared

Bletilla striata is a very commonly used medicinal herb, and its range of uses is extremely wide, so it is often used in our daily lives, but it generally does not appear in its most primitive state. Bletilla striata was formerly a wild plant, and it was only in recent years that large-scale artificial cultivation began, but many people say that the survival rate of Bletilla striata planting is not very high, so how can planting improve the survival rate of Bletilla striata? Let us learn about it together with Qinnong Network below.

1. Seedling Selection

The survival rate of Bletilla striata is to a large extent related to the quality of the seedlings. When selecting seedlings, we often overlook many details. We only know that seedlings should be selected with relatively thick tubers and effective buds, but our best method is to choose domesticated seedlings. The survival rate of this kind of seedling is as high as 80% to 95%. That is because domesticated seedlings also differ: one- to two-month domesticated seedlings have a survival rate of only 80%, while four- to five-month ones have a survival rate of 90%, and only nine- to ten-month ones can have a 95% survival rate. So it is best to choose the seedlings with the highest survival rate, at least so that aside from external factors, their survival rate is a bit higher.

2. Soil Selection

Considering the survival rate of Bletilla striata, the soil for planting Bletilla striata is best soil with relatively loose texture, such as sandy soil or soil with relatively little clay, etc. At the same time, the planting site must be relatively level and must not be full of pits and bumps, as this is not conducive to the survival of Bletilla striata. In particular, soil with relatively high clay content is the least suitable for planting Bletilla striata. Planting Bletilla striata in such soil makes it basically difficult to survive, and even if it survives, the yield of Bletilla striata is not high and the quality is not much better.

3. Seedling Treatment

In order to improve the survival rate of Bletilla striata planting, we can treat the seedlings accordingly before planting. We need to wipe off some poorly growing buds from the tubers of the purchased seedlings, then apply a layer of medicinal solution to prevent infection by pathogens. Next, put the whole tuber into clean water filled with plant ash and soak it. Of course, we can also directly coat the surface of Bletilla striata with a layer of plant ash or an agent that enhances immunity. If a medicinal agent is used, the concentration must not be too high, as this will affect the quality of Bletilla striata.

4. Temperature Management

The temperature suitable for the growth of Bletilla striata is best kept stable at around 20°C to 25°C. Most regions of our country have relatively distinct four seasons, and temperature changes are also relatively large. For example, the highest temperature in summer can reach more than 30°C, making it feel as if it is being roasted over fire, while in winter it can reach several degrees below zero, etc. So for Bletilla striata, it is very difficult to still adapt to such an environment, so we need to use artificial means for heat dissipation and insulation, and only in this way can we improve the survival rate of Bletilla striata.

5. Water Management

Although Bletilla striata is a relatively drought-tolerant plant, Bletilla striata has very strict water requirements in its early growth stage. If the water is not up to standard, whether too high or too low, it will affect the survival rate of Bletilla striata. Under normal circumstances, before planting we need to water the land once, then wait until the buds grow out, at about 10 cm, and then water again. The soil moisture level must be maintained, so that it will not die during the seedling growth process. Next, if there is a lot of rain, the rainwater should be drained in time, otherwise Bletilla striata is also very prone to disease, and the mortality rate is still very high, so attention must be paid. The water in the field is best kept at around 50% to 60%.
