How to Grow Largeleaf Gentian? A Detailed Guide to the Latest Planting Methods
Largeleaf gentian, also known as Qinjiao or big-leaf gentian, is a perennial herbaceous plant in the Gentianaceae family. It has extremely high medicinal value and is often used to treat rheumatic joint pain, tuberculosis, tidal fever and jaundice. Although we are not very familiar with largeleaf gentian, it is grown quite widely in our country, with especially high yields in Inner Mongolia, Ningxia, Hebei, Northeast China and other regions. So today the editor will mainly walk you through its planting methods. Let's take a look.
1. Site selection and soil preparation
Largeleaf gentian likes moisture and cool conditions, is cold-tolerant, fears waterlogging and cannot tolerate strong light. Wild largeleaf gentian generally grows in riverbanks, roadsides, ditch edges or sloping land. So when choosing a planting site, we need to select according to the growth habits of largeleaf gentian. It is best to choose a semi-sunny area far from polluted areas, with sufficient water, sufficient soil fertility and high humidity. The soil is best sandy loam or humus soil. Deeply plow the land, clear away grass roots, tree roots and other debris from the soil, apply sufficient decomposed farmyard manure and turn it in, finally break up the clods, level the ground and open drainage ditches.
2. Sowing and raising seedlings
Largeleaf gentian can generally be sown in spring and autumn. For autumn sowing, note that it is best done in early October, while spring sowing is best done in April. First we need to raise seedlings for a period, and sowing can be done by broadcasting or drilling. Broadcasting is generally suitable for lazy growers, while drilling makes seedling-stage management easier. After sowing, cover with a layer of rice straw to keep warm and moist. After the seedlings emerge, promptly uncover part of the straw so as not to affect seedling growth.
3. Transplanting and field planting
When the seedlings grow to about 6 to 10 cm, reasonable thinning is needed, but at this point they cannot yet be transplanted. Generally it is best to wait until the seedlings grow to about 15 to 20 cm before transplanting and field planting. When planting, they are usually set out at a row spacing of 30 cm and a plant spacing of 20 cm. When field planting, after planting each row you need to cover with soil and firm it down, so as not to affect the survival rate of transplanting.
4. Field management
Field management of largeleaf gentian is relatively simple, so largeleaf gentian is a very suitable planting project for lazy growers. Generally after field planting and survival, carry out the first hoeing and weeding, and water frequently to maintain soil moisture in the field. Next is reasonable fertilization: according to the growth of largeleaf gentian, use fertilizer types scientifically, most commonly manure and urine water and decomposed oil cake fertilizer. Then, during the growth process, build shade sheds and reasonably control the light conditions in the field. Finally, do a good job of pest and disease control. The main disease is leaf spot, which we can generally prevent at sowing time by treating the seeds, and in the later stage by doing good field management; in the early stage of disease onset, use mancozeb for control.
From the growth habits of largeleaf gentian we can see that it has tenacious vitality. At the same time, we also understand that its requirements for water, temperature and light intensity are very strict, so in the process of planting we need to fully grasp these key points.
