Bletilla striata high-yield cultivation technique tutorial, latest planting method explained in detail
Bletilla striata is the rhizome of an orchid family plant, an important medicinal plant, and in traditional Chinese medicine it can treat many diseases. Therefore, artificial cultivation is widespread, and in the course of numerous cultivation efforts, a great deal of cultivation experience has also been accumulated. What follows is mainly to introduce to everyone the process of planting Bletilla striata and the details to pay attention to, as well as the specific techniques of cultivation management.
1. Planting land
The wild environment of Bletilla striata is among mountain forests, so it is generally a relatively shady environment, without receiving strong light exposure; the soil under the forest is not exposed to sunlight, the root system conserves water, so it is relatively tolerant of moisture and needs to grow in a humid environment; leaves fall all year round, accumulate and rot, forming rare humus soil, rich in nutrients, so it needs fertile land. But it also cannot have water accumulation or lack of light.
2. Preparing facilities
For land planting, generally flat land is used for planting, with no natural forest, so it is necessary to prepare some shade facilities to create a scattered-light environment. In the planting area, drip irrigation or seepage irrigation facilities must be installed, mainly for future irrigation and moisture retention in the planting area. It grows well.
3. Planting method
It mainly relies on the previously selected seed bulbs for planting. Before planting, clean them thoroughly, then soak the roots in rooting powder; do not soak the seed bulbs. Then dig trenches for planting, planting directly in rows; after planting, cover the roots with soil and spread them out, cover the seed bulbs with a shallow layer of soil, and also leave half of them above the soil surface. After planting, some decomposed sawdust can be spread over the surface to retain moisture. Watering is then sufficient.
4. Temperature and moisture
Maintain a cool ambient temperature; it should not be hot, nor cold. Keeping it at around 18 to 20 degrees is best; it can still grow if it does not exceed 25 degrees, but exceeding that will have some effect. It is mainly suitable for planting in temperate zones. It requires a humid soil environment, but there must be no water accumulation. Generally, maintaining 60% soil moisture content is sufficient, ensuring that the surface soil is moist.
5. Pest and disease control
The main disease is leaf spot and gray mold. After onset, it mainly harms the leaves. For control, remove diseased leaves at the early stage of onset and promptly spray chemicals. For mild onset, a 500-times solution of 50% carbendazim can be used for spraying; for severe onset, a 500-times solution of 65% zineb powder can be used for spraying. The main pest is the white grub, which mainly bites and feeds on the rhizome. It can be caught manually or trapped. A 90% trichlorfon solution can be used to drench the roots.
The main thing in Bletilla striata cultivation is to do a good job in planting and cultivation management, mainly to create a suitable growing environment and then maintain the growing environment well, so that Bletilla striata grows well.
