The whole herb can be used as medicine, with the effect of clearing heat and detoxification, promoting blood circulation and hemostasis. it is often used for high fever, lung carbuncle, swollen throat, toothache, hemorrhoids, poisonous snake bites and so on. So how do you plant the mackerel? Let's take a look.

1. Land selection and preparation

It can be planted on hillside, riverside, farmland, acidic and barren soil before and after the house, but it grows slowly, and its flowering quantity and fruit number are also relatively small, which affects the ornamental value and medicinal value. Therefore, it is appropriate to choose high-lying, deep soil, loose soil, rich in organic matter loam planting, in early spring is the beginning of soil preparation, the soil will be scattered, rake fine leveling, ridging, make a good drainage ditch.

2. Methods of reproduction

Artificial cultivation generally chooses ramet propagation, which can be transplanted after early spring rain, and the survival rate is very high, but the survival rate is low in summer high temperature or autumn and winter dry season. Seeds can also be obtained from wild resources for reproduction, but in different growth environments, the seeds of wild resources will be affected by external conditions, and the growth situation will be different. therefore, we should try to choose varieties with fast growth, large flowering quantity and large fruit to avoid low planting efficiency.

3. Cultivation and management

Because of its cold tolerance and barren tolerance, it does not need too much management after transplanting, but the growth rate is slow. Attention should be paid to weeding in the seedling stage or after transplanting, so as to avoid weeds affecting its growth. When it covers the surface, weeds are extremely difficult to invade, so weeds need to be weeded. Because of its own wild plants, it has strong adaptability and resistance to diseases and insect pests, and no diseases and insect pests have been seen in artificial cultivation, so there is no need for chemical control.

4. Fertilizer and water management

In addition to fertilizer consumption during soil preparation, 400-500 kg of nitrogen, phosphorus and potassium fertilizer can be applied per mu, with an appropriate amount of micro-fertilizer. After one month of planting, according to the growth of the plant, 100 kg of dilute dung and urine water or urea solution can be irrigated per mu. Appropriate amount of phosphorus and potassium fertilizer and boron fertilizer can be applied during flowering, budding and fruiting, which can increase the flowering quantity and seed setting rate. The demand for water is not high. When planting in the south, drainage measures should be taken in the rainy season to avoid rotting roots, but appropriate watering should be done in times of drought to avoid low seed setting rate, fruit cracking and so on.
