The Latest Planting Methods and Key Technical Points for Rabdosia rubescens

Rabdosia rubescens is a traditional Chinese medicinal herb mainly used to treat sore throat, tonsillitis, tracheitis and joint rheumatism, and it also has a certain moderating effect on breast cancer and intestinal cancer, possessing very good health-care effects in cancer prevention and anti-cancer. It is increasingly accepted in our daily lives, so how is Rabdosia rubescens planted? Let us learn its planting method together below.

1. Site selection and land preparation

The planting site for Rabdosia rubescens is generally fairly flat, and the soil structure should be relatively complete, sandy soil rich in humus and nutrients, with good drainage and permeability, but it must not be heavy sandy soil, as such soil tends to become compacted and is not suitable for the growth of Rabdosia rubescens. Land preparation is generally carried out in winter, plowing the land deeply to let it weather as much as possible, then fine plowing in the following spring, and spreading enough barnyard manure as base fertilizer, and finally raking it level and opening furrows about two meters wide to make beds.

2. Scientific planting

Seed sowing is generally at the end of March each year, when the soil temperature has generally slowly risen back to about 15 degrees, while rhizome planting can be carried out at the beginning of March or the end of February, when the soil temperature is about 10 degrees. Before planting, the seeds or rhizomes need to be treated. Seeds can generally be soaked in potassium permanganate, taken out after one day, rinsed clean of residual chemicals with clear water, drained of water and then sown, while rhizomes need to be soaked in carbendazim for about ten minutes, then taken out, drained of water and planted. After such treatment, seedlings emerge much faster, and the plants have stronger resistance.

3. Reasonable close planting

At the time of initial planting, the planting density of Rabdosia rubescens is about 25 cm between rows and about 20 cm between plants, and when Rabdosia rubescens has grown to a certain size we need to transplant it again, and when transplanting, it can be finally planted at a density of about 45 cm between rows and about 40 cm between plants.

4. Field management

After final planting, we should pay attention to checking the survival and growth of Rabdosia rubescens in the field. If dead seedlings, broken seedlings, weak seedlings or diseased seedlings appear in the field, they should be pulled out in time, especially diseased seedlings, so as not to affect the growth of other healthy plants, and after cleaning and disinfecting the soil, replanting should be carried out. At the same time, intertillage and weeding should be carried out according to the growth of weeds in the field, to stop losses in time and enhance soil permeability. In this month after planting, water management is crucial, and watering should be done promptly to maintain field moisture, but if water accumulates in the field or there is too much water in the field, it needs to be drained in time. Apart from the base fertilizer, Rabdosia rubescens generally only needs one topdressing, mainly with urea.

5. Pest and disease control

The most common disease of Rabdosia rubescens is leaf spot, which mainly occurs under high-temperature and rainy conditions in summer or high temperature with little rain. In the early stage of the disease, we can use carbendazim for control. Next, the main pest of Rabdosia rubescens is the beet armyworm, which we can trap and kill with black light lamps, or poison with phoxim, or strengthen field management and clean up weeds in the field in time.
