Seedling raising and transplanting of panax notoginseng should be scientific. How to transplant the seedlings of panax notoginseng?

It is very important to plant Panax notoginseng and raise seedlings. Poor seedling raising will affect the yield. When raising seedlings, it should be carried out 2~3 months ago. Before raising seedlings, the land must be turned over several times to make the soil finer. You can do it again before sowing, and then ditch in the field, with a height of 18 cm and a width of about one meter. After completion, you can put 3000~4000 kilograms of base fertilizer in it and mix it evenly with the soil inside to ensure the fertility of the soil.

Before this, the ground should be trimmed and leveled. According to 6×6, the depth of each cave is about 1.5 cm, and a seed can be put in it. After putting it away, cover it with soil and spread it with a layer of straw, which can effectively alleviate soil hardening and ensure a good seedling rate. Generally, we sow in winter, produce grain in March, and grow neatly in April. According to the yield of 6.5438 million grains per mu, it weighs 8.5 kilograms and can be transplanted in one year.

When transplanting, you should choose to raise seedlings after one year. Be sure to trim the field before. It is best to do it after heavy snow or during the winter solstice. It is necessary to dig out all the seed strips on the seedbed, then cut off the stems and leaves, put them in the hole, add some mixed fertilizer and cover them with a little fine soil. Trenching should be carried out according to 24×20 or 27×24, with a depth of 3 ~ 5cm. Pay attention to the angle between the seedlings and the bottom of the ditch when transplanting, which is 20~30 degrees. Panax notoginseng seedlings, usually 8 ~ 15 cm high, grow into shoots after one year and are used as seedlings. One-year-old Panax notoginseng seedlings are also called seven-year-old seedlings. The germination time of Panax notoginseng seed strips is from the middle and late June to the middle and late October of the following year 10, so the dormant buds of Panax notoginseng have not yet germinated. Notoginseng seedling method: annual Notoginseng can be dug from one side of the seedbed to the other with sharpened bamboo sticks or wooden sticks. After disinfection, rinse with water, dry and transplant. Cutting grass, pine leaves, crop straws, etc.

Matters needing attention after transplanting two-year-old Panax notoginseng: transplanting seedlings in June+February of 65438 every year is called two-year seven. Panax notoginseng is a biennial plant, which usually appears from March to April and spreads its leaves. In the middle and late May, flower buds, buds and bolting gradually appeared at the top of the stem. It blooms and bears fruit from August to September. Red seeds gradually mature in late June at 65438+1October, and can be harvested and sown from June165438+1October to February at 65438+February. After picking the red seeds, Panax notoginseng enters the dormant period, waiting for germination, and unfolds its leaves in February-March of the following year.
