How to Improve the Survival Rate of Bletilla striata Planting? Master These Methods
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 only in recent years did large-scale artificial cultivation begin, but many people say that the survival rate of Bletilla striata planting is not very high, so how can we plant it to improve the survival rate of Bletilla striata? Let's learn about it together with Qinnongwang 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 the seedlings should be selected with relatively thick tubers and effective sprouts, but our best method is to choose domesticated seedlings. The survival rate of this kind of seedling is as high as 80 to 95 percent. That is because domesticated seedlings also differ: one- to two-month-old domesticated seedlings have a survival rate of only 80 percent, while four- to five-month-old ones have a survival rate of 90 percent, and only nine-month-old ones can have a survival rate of 95 percent. So it is best to choose the seedlings with the highest survival rate, at least so that apart from external factors, their survival rate is a bit higher.
2. Soil Selection
Considering the issue of the survival rate of Bletilla striata, the soil for planting Bletilla striata should preferably be relatively loose in texture, such as sandy soil or soil with relatively little clay, and so on. 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 viscosity is the least suitable for planting Bletilla striata. Planting Bletilla striata in such soil basically makes it difficult to survive, and even the Bletilla striata that does survive will not have high yield, and its quality will not be much better either.
3. Seedling Treatment
In order to improve the survival rate of Bletilla striata planting, we can carry out corresponding treatment on the seedlings before planting. We need to wipe off some poorly growing sprouts on the tubers of the seedlings we bought back, then apply a layer of liquid medicine to prevent infection by pathogens. Next, soak the entire tuber in clean water filled with plant ash. 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 chemical 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 to 25 degrees Celsius. Most regions in 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 degrees Celsius, making it feel as if it is being roasted over fire, while in winter it can drop to minus a few degrees Celsius, and so on. So for Bletilla striata, it is very difficult to still adapt to such an environment. Therefore, we need to use artificial means for heat dissipation and heat preservation. 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 does not meet the standard, whether too high or too low, it will affect the survival rate of Bletilla striata. Generally, before planting, we need to water the land once, and then after the sprouts grow out, when they are about 10 cm, water again, and keep the soil moist, so that it will not die during the process of growing seedlings. Next, if there is relatively 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 also very high, so be sure to pay attention. The water in the field is best kept at around 50 to 60 percent.
