First of all, we need to raise seedlings for a period of time, which can be sown by sowing and strip sowing. Sowing is generally suitable for lazy people to plant, while strip sowing is convenient for seedling management. After sowing, you need to cover a layer of straw for heat preservation and moisturization. after the seedlings are unearthed, the straw should be opened in time so as not to affect the growth of the seedlings.

3. Transplanting and planting

When the seedlings grow to about six to ten centimeters, it is necessary to make a reasonable interseedling, but it is not possible to transplant at this time. Generally speaking, it is best to wait for the seedlings to grow to about 15 to 20 centimeters before transplanting. When planting, it is usually planted at an interval of 30 cm between rows and 20 cm between plants. When planting, each row of planting needs to be compacted with soil, so as not to affect the survival rate of transplantation.

4. Field management

The field management of Gentiana is relatively simple, so Gentiana is a very suitable planting project for lazy people. Generally, after planting, weeding is carried out for the first time, and regular watering is needed to maintain the soil moisture in the field. The second is to carry out reasonable fertilization, according to the growth of Gentiana, scientific use of fertilizer species, usually the most commonly used is feces and urine water and rotten cruller fertilizer. Then, in the process of growth, build a shade shed, and reasonably control the light in the field. The last is to do a good job in the prevention and control of diseases and insect pests, the most important disease is leaf spot disease, generally we can prevent through seed treatment when sowing, do a good job in field management in the later stage, and use mancozeb in the early stage of the disease.

We can know that Gentiana has indomitable vitality through its growth habits. At the same time, we also understand that its requirements for moisture, temperature and light intensity are very strict, so we need to fully grasp these key points in the process of planting. Today, the editor wants to take you to understand the planting method of Gentiana macrophylla. If you have any other questions, you can also leave a message for advice to the editor.
