What are the precautions for planting Dictamnus dasycarpus
Dictamnus dasycarpus is the root bark of a plant in the Rutaceae family, with effects of clearing heat and drying dampness, dispelling wind and removing toxins, and fighting cancer. It is widely used in clinical practice and has high medicinal value. As people's awareness of health preservation strengthens, its market demand is increasing, and its price is gradually climbing. Artificial cultivation is highly effective, but there are many issues to pay attention to when planting. Let's take a look below at the precautions for planting Dictamnus dasycarpus.
1. Seed treatment
Dictamnus dasycarpus is mainly propagated by seeds. When planting, the seedlings need to be raised for one year before transplanting. However, its seeds have the characteristic of physiological after-ripening, so sowing in the same year can only play a role in promoting germination and cannot make them germinate. If you want them to germinate in the same year, they need to be treated. Stratifying the seeds can break seed dormancy. The specific method is to put the seeds in a container, pour in clean water and soak for 2 days, then remove and air-dry them, then mix the seeds with fine sand at a ratio of 3:1 for seed dressing. Choose a well-drained place and dig a pit, bury the seeds in it, make an overwintering trench, and dig them out in the spring of the second year so they can germinate normally.
2. Weed control
After the seedlings emerge, weeds should be removed in time, but deep cultivation is not suitable. Weeding can be done by pulling weeds by hand, or chemical agents can be used for weed control. The herbicide chlorotoluron can be sprayed, and after spraying, cover with a layer of plant ash to prevent the chemical from volatilizing. It can also be mixed with soil to make poisoned soil and spread on the ground, which can also achieve a good weeding effect. In addition, weeds should also be removed in time after transplanting, but during the growing period, the leaves of Dictamnus dasycarpus are toxic and irritating to human skin. Protective measures should be taken when weeding to avoid skin contact with the leaves, which can cause skin redness, swelling, and itching.
3. Fertilization
To achieve high yield of Dictamnus dasycarpus, fertilization is an important measure. From May to June each year, topdressing should be applied 2 times, with 750-1000 kg of farmyard manure per mu, or 10-12 kg of urea per mu. After the Start of Autumn, during the rapid growth period of the roots, a foliar fertilizer can also be sprayed once to promote vigorous leaf growth and increase yield.
4. Removing flowers and buds
May to June is the flowering period of Dictamnus dasycarpus. For plots not kept for seed production, in order not to cause high consumption of nutrients, concentrate nutrients on the root system, and promote root growth and development, the flower buds should be removed in time when the plant is budding, but care should be taken not to damage the stems and leaves.
