How to plant gentian planting methods and matters needing attention

Gentian is a kind of herb with ornamental value. It likes the moist environment and has certain requirements for the soil. It uses acidic soil because it is colorful, so many people like it. But friends who want to plant do not know the method and what it needs to pay attention to. Let's introduce it below.

How to grow gentian

After the seeds send out seedlings, the unhealthy and small seedlings can be pulled out, leaving sturdy seedlings for cultivation. Weeding should be carried out frequently during the seedling period, which can be pulled out directly, so as not to let weeds absorb nutrients from the soil, resulting in nutrient loss of seedlings, let alone wait for the grass to grow up in weeding, so it is easy to hurt the roots of Gentiana.

If there are turtles or caking in the soil, the soil should be loosened in time. Loose soil should be careful, not too deep, otherwise it is easy to hurt the seedlings, at the same time will also take the seedlings out of the soil. Transplanting and planting can also be carried out when loosening the soil. Loosen the soil for 2 to 3 times after transplanting. After transplanting, a topdressing should be carried out, and the leaf surface can be sprayed and fertilized by spraying. A topdressing is carried out during budding and blooming and fruiting. In 3 to 4 years, the soil can be fertilized once, and the soil should be paved after fertilization.

Planting methods and matters needing attention of Gentian

1. Soil selection: choose relatively moist, sandy soil rich in organic matter.

2, the choice of environment: gentian grass likes abundant sunshine, so you can choose a place where the sun can shine directly.

3. Prepare before planting: the basic fertilizer should be sufficient, then flatten the surface of the soil and make ridges and furrows to plant gentian grass.

4. Flower thinning and bud picking: for fruiting plants, if the number of flowers is far from the number of fruit, it should be picked and cut in time so as not to consume unnecessary nutrients. If it is not picked and cut in time, the final fruit will fall before it is fully formed.

5. Precautions: attention should be paid to the prevention and control of quenching disease, spot blight and brown spot disease.

Propagation method of gentian

1. Seed propagation

The seeds of gentian are very small, and the seeds should germinate in places with good warm and wet conditions and good light conditions. Seeds can germinate in about 25 degrees in a week, and grow slowly in the seedling stage, so avoid strong light. In order to strengthen the management of the seedling stage and keep the seedling bed moist, Reed curtains can be used to block the light.

2. Split-root reproduction method

The underground root and rhizome can be dug out in autumn, do not hurt the winter buds. Cut the rhizome into three or more stem segments, bury it in the soil, cover the soil, and water to keep the basin soil moist.

3. Cutting propagation method

The adult plant branches should be cut off before flower bud differentiation, and the leaves in the lower part of the branches should be cut off to reduce evaporation. Cuttings should be watered and moist immediately after cutting on the seedling bed. When the temperature of the basin soil is between 18 and 28 degrees, it will take three weeks to take root.

How to make gentian New Year's Day blossom

1. Adjust the temperature

In general, temperature regulation is a better method, and it is more convenient to adjust, and it will not cause harm to plants than using drugs, so this is the first choice. First of all, if you want a plant to blossom, you can't continue to leave it outside.

Then, we have to judge how to regulate the temperature according to the specific situation. If you feel that it will blossom before New Year's Day arrives, then appropriately lower the temperature and delay the flowering date; if it is coming to New Year's Day soon and there is no sign of blooming, then it is necessary to raise the temperature appropriately to make its flowering earlier.

2. Regulation of water and fertilizer

The principle of this method is also easy to understand, which is the way to adjust the flowering period by adjusting the external environment (water and nutrients) for plants. If the plant will blossom before New Year's Day, then reduce the amount of watering and fertilization to delay flowering.

On the contrary, try to provide as much water and nutrients as possible. This method is also easier to implement, but the effect is not obvious compared with the first method. Therefore, we can consider matching with other methods.

It seems that the planting of gentian is not as difficult as we think. usually we usually use the method of sowing and planting, as long as we do a good job in the prevention and control of diseases and insect pests, but if you want to control the florescence of gentian, you still need to make some efforts, the adjustment of temperature and water and fertilizer is the key.
