What should I pay attention to when planting Bupleurum? Six principles of Bupleurum cultivation

Six principles of Bupleurum cultivation:

First, the selection of six principles of Bupleurum cultivation

The growth habit of Bupleurum is to be afraid of cold and drought, and it is reasonable to choose a deep, loose and fertile soil with good drainage. The fertilization should be based on farmyard manure and phosphorus and potassium fertilizer. Generally, 1,500 kg of farmyard manure is applied in one mu. 10-12 kg of diammonium phosphate is used as the base fertilizer.

Second, the four principles of Bupleurum planting

Turn the plot deeper by 25cm, carry out deep ploughing and fine work, and lay a good foundation for planting Bupleurum. The width between the field and the hoe should be 20cm and the depth should be 10cm. The width and width should be the same. The width of the flat surface is generally 0.6 meters. If you want to cover the film, it should be wide and wide according to the width of the Bupleurum. TIPS: The slopes are not allowed to be squatted, but they should be leveled and the drainage ditch should be opened at intervals of about 1.3 meters.

Third, the seed treatment of the six principles of Bupleurum cultivation

The seedling emergence rate of Bupleurum seeds is relatively low, so it is necessary to soak seeds with potassium permanganate solution to increase the emergence rate of Bupleurum. After soaking seeds, screening should be carried out to screen out bad seeds to ensure a better emergence rate of Bupleurum.

4. Seeding of the six principles of Bupleurum cultivation

The sowing time of Bupleurum must be mastered. It is usually planted in 3-4 months. The seeding of one mu of land should be controlled at 2kg. Before planting, the seeds and the ash should be mixed evenly into the ditch. The ratio is 1:1. And then covered with fine soil. TIPS: Covering cultivation can not fill the small ditch, so that the membrane and the groove surface are 1-2cm space, to prevent the Bupleurum from being burned by the film after emergence.

Five, Bupleurum planting six principles of moisturizing

After sowing, the Bupleurum should cover the wheat straw or the mulch film in time for heat preservation and heat preservation. TIPS: The spring sowing covered wheat straw does not need to cover the mulch film, and the winter should be covered to prevent the wind from being blown off.

6. Field management of six principles of Bupleurum cultivation

When the Bupleurum seedlings are 3.6cm high, weeding should be carried out. After weeding, we can apply 1500 kg of animal manure. When the seedling height is 5.6cm, the seedlings are planted, and the seedling height is 10cm. The seedlings should be fixed. After the seedlings are planted, timely fertilization should be carried out to keep up with the growth of Bupleurum.
