In recent years, medicinal planting industry has developed rapidly in Zhejiang, Yunnan, Anhui and Guizhou. However, many farmers cannot accurately master the cultivation techniques of Dendrobium. Based on this, the microbial fertilizer expert Jinbao summed up the Shimao's standardized planting points to the majority of farmers' friends.
1. Dendrobium candidum planting seedbed management
There are two methods to treat the soil needed for land cultivation in greenhouses. One is the sun exposure and the use of pungent sulfuric acid as the insecticidal treatment to kill the residual pests or eggs in the soil; the other is the use of finished soil starters such as The golden babe base soil starter is used for the fermentation of the soil base. The first kind is very easy to produce sterilization is not complete and the pests affect the post-management, so the commercial starter is more appropriate. In the shed, brick or stone is used to build a seed bed 10 cm high and 1.5 m wide. Spread a layer of 10 cm thick gravel and other materials with good water permeability, and finally spread a thick, 6 cm fermentation substrate. A 40-cm wide walkway is reserved between the seedbed and the seedbed.
2. Dendrobium candidum planting, transplanting and planting management
Choose disease-free, robust seedlings for planting, in order to facilitate the management of seedlings, we must also choose uniform-sized seedlings. The treated seedlings were planted on the substrate at a spacing of 10 cm per cluster in 5 clusters. It is advisable to cover the root completely with the substrate when colonizing. Early planting light should be reduced, pay attention to shading, when the seedlings are still relatively weak, the light is too strong and easy to dehydration. The optimum temperature for the growth of Dendrobium is 20-32°C. During the high-temperature season, shading, ventilation and spraying are required to reduce the temperature in the greenhouse; in the low-temperature season, heating and heat preservation are required. In addition, when the growth is strong, it is best to keep the humidity of the air inside the planting environment at around 60%-90%. The principle of humidity control is that high temperatures require high humidity, low temperatures require low humidity but high temperatures and high humidity should be enhanced ventilation to prevent bacterial and fungal diseases.
3. Dendrobium candidum growth management
Due to the high temperature and high humidity environment, weeds and weeds often compete with nutrients on the substrate. Therefore, weeding must be done in time. In general, Dendrobium candidum is planted twice a year after planting, respectively in mid-April and early November. The weeds that grow in and around the Dendrobium candidum should be taken out to ensure ventilation. In the summer hot season, weeding should not be done so as not to affect the normal growth of Dendrobium candidum. In addition, Shiqi must pay attention to pruning. Before spring sprouting or harvesting, some old branches and dead branches as well as overgrown stems should be cut off to promote the growth of new shoots. In addition, five years after planting Dendrobium officinale, the plants sprouted, the substrate became moldy, and the plants grew poorly. Therefore, it is necessary to carry out the hoeing so as to remove the decayed old roots to promote the growth of the plants and increase the yield and income. You can also take this opportunity to replant new seedlings.
4. Dendrobium candidum harvesting and processing
Dendrobium candidum is usually harvested from late autumn to early spring. The new stems of Dendrobium candidum gradually matured in the fall, and the growth slowed down. At this time, the leaves yellowed and the plants gradually entered dormancy. Wait for the leaves to fall or occasionally leave 1-2 leaves at the tip of the shoot to harvest timely. When harvesting, cut the branches with scissors and cut them to the level to reduce the loss of nutrients and facilitate wound healing. In addition, the roots of the stems are left with 2-3 nutrients for the sprouting of sprouts in the coming year.
