Planting techniques of Bupleurum

Bupleurum is alias smoked, mountain vegetable, mushroom grass, firewood grass, is a commonly used table medicine, with the effect of relieving the surface, soothing the liver and rising yang, mainly used to treat cold and fever, cold and heat exchange, liver depression and qi stagnation, irregular menstruation and so on. So how to grow Bupleurum? Let's take a look.

1. Land selection and preparation

Bupleurum grows mainly under sandy grasslands, dune meadows and open forests on sunny slopes, so try to choose sandy soil instead of clay and low-lying land prone to stagnant water. Before planting, it is necessary to apply base fertilizer combined with soil preparation, which is mainly organic fertilizer, mixed with appropriate amount of phosphate fertilizer or compound fertilizer, sprinkle it evenly, and then plough and rake it evenly, so that it can be evenly mixed with the soil. Then make the border or ridging, the height of the border is 15-30 cm. The width is 1-1.3 meters.

2. Sowing and raising seedlings

The sowing method can be used by direct seeding, seedling raising and transplanting, and direct seeding is generally used in a large area, and the sowing time is carried out after thawing in winter or in spring. When sowing, pour enough water on the border surface, open a shallow trench according to the row spacing of 15-18 cm, and the ditch depth is 1.5-2 cm. Then spread the seeds evenly into the ditch and cover a layer of fine soil with a thickness of 0.7-1 cm. Seedlings can emerge within two weeks of sowing. The sowing time of seedling transplanting is generally from March to April, can be strip sowing or hole sowing, the row spacing of strip sowing is controlled at 10 cm, the seeds are evenly scattered into the ditch, water can be covered with soil, and can also be covered with straw or plastic film to keep warm and wet to facilitate seedling emergence. Hole sowing is a hole sowing on the border surface, which is more tedious and rarely used.

3. Transplanting

Using the method of seedling transplanting, when the seedlings grow to 7 cm, you can transplant to the field, pay attention to the row spacing when transplanting, the best row spacing is 15-20 cm, and the plant spacing is between 7-10 cm. Transplanting seedlings when watering once to facilitate the seedlings, and after transplanting should also be watered enough to help slow the seedlings and improve the survival rate of transplanting.

4. Field management

When transplanting survived, weeding should be started, and intermediate ploughing after weeding can loosen the soil, increase soil permeability and promote root growth and development. When the seedlings grow to 15-18 cm, you can top fertilizer once, mainly apply nitrogen fertilizer or urea, be sure to weed before fertilization, but do not damage the seedlings. After fertilization, it can be watered, dilute the fertilizer, reduce the concentration, make it infiltrate into the soil as soon as possible, and accelerate the absorption rate of the root system.
