Detailed Explanation of Rabdosia rubescens Planting Methods and Cultivation Techniques
Rabdosia rubescens is a medicinal herb mainly used to treat sore throat, tonsillitis, tracheitis and rheumatic joint diseases, and it also has a certain moderating effect on breast cancer and intestinal cancer. It has a very good health-care effect in preventing and fighting cancer, and is increasingly accepted by everyone in our lives. So how is Rabdosia rubescens planted? Below let us learn its planting methods together.
1. Site Selection and Land Preparation
The planting site for Rabdosia rubescens is generally relatively flat, and the soil structure should be relatively complete and be sandy soil rich in humus and nutrients. The soil drainage and permeability should both be relatively good, but it must not be heavy sandy soil, as such soil easily becomes 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 waiting until the following spring to carry out fine cultivation, 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 carried out 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 in early March or at the end of February, when the soil temperature is about 10 degrees. Before planting, the seeds or rhizomes both need to be treated. Seeds can generally be soaked in potassium permanganate, then taken out after one day, rinsed with clean water to remove residual chemicals, drained of water, and then sown, while rhizomes need to be soaked in carbendazim for about ten minutes, then taken out and drained of water before planting. After such treatment, the 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 generally 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. 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 the month after planting, water management is crucial. Watering should be carried out in time to maintain field humidity, but if water accumulates in the field or there is too much field moisture, it needs to be drained in time. Apart from base fertilizer, Rabdosia rubescens generally only needs one topdressing, mainly with urea.
5. Pest and Disease Control
The most common disease and pest of Rabdosia rubescens include leaf spot disease, which mainly occurs under conditions of high temperature and much rain or high temperature and little rain in summer. In the early stage of the disease, we can use carbendazim for control. Next, the main pest of Rabdosia rubescens is the beet armyworm. We can use black light lamps to trap and kill it, and we can also use phoxim for poisoning control, or strengthen field management work and clean up weeds in the field in time.
